We are very pleased with the Joint Venture. The 26 inch wheels have held up well, and really is a no-tools job to change a tire. I can't imagine not having independent cranking, nor can I imagine not having disk brakes (we do have some serious up and down in places in Ohio).

It is a pleasure to ride and work on a well-built machine. if you know anyone who needs confirmation that the investment is a good one, send 'em my direction.

We purchased our Da Vinci from Acme Bicycle last November. We now have 2,600 miles on our tandem in less then a year and love it! We have taken it with us to do the 3-State 3-Mountain Challenge and the Copper Triangle. It is much easier to travel with. While the Da Vinci was in the shop for a tune up we tried to ride our old Santana. It was not fun. We really enjoy the Da Vinci.

Hi,

My Wife and I are in our early 60’s and my wife never has rode a bike by herself. I got interested in riding a couple years ago watching Lance. I could never get my wife to ride a bike by herself. One day riding by myself I saw a couple ride by on a Tandem, I stopped called my wife on my cell and asked her to find the nearest Bicycle shop that sold Tandems. We had a Tandem that day!

We have been riding together ever since!

We began with just any Tandem. It was a road bike and had 18 speeds BUT! We found it had many difficulties because it was NOT a Davinci Tandem. My wife would be trying to get her feet locked in the pedals while I was trying to get the Bike moving forward (not good), and at 60 plus 18 speeds just would not get us up many of the bigger hills.

I began doing some serious research on Tandem bikes and (thank you Lord)! Found the Davinci Website! We just cannot say enough good things about our Davinci Tandem. AND It looks GREAT!

Guys, I wanted to personally thank you for your work on my new bike (the purple In2ition). I haven't been this excited for years. Here's a note I sent to friends and family earlier this morning.

My new bike arrived! Because of rain and time constraints we've still got less than 20 miles on it. Bethany is wearing new shoes, socks, and gloves, and her feet are attached to new pedals. There are two trip computers, one each, although hers is the nicer of the two. Acme gave us matching jerseys, but we're out for a quick ride in these pictures and aren't wearing them. This weekend we'll pick up matching helmets. They custom make and paint these, and I'm told they'd never done that color combination before, so it's the only one of its kind in the world. Her name is Annabelle.

Todd & Brian,

We just got back from our second tandem trip. We went to New Zealand for three weeks in January, 2006 and off to Holland from June 30 to July 9, 2006 . We really appreciate the 26" wheels! Packing the bike is much easier than it would be with 27" wheels.

I have included a picture that was taken in Holland. This is on the dike built in the early 1930's that separates the Waddenzee (North Sea) from the Ijssel Meer (the lake that was created by cutting off the North Sea). I sent the full-sized picture in case you want to use it. If this is too large to handle easily with your software, just hit reply and I will send the email version.

One funny story. When we were in New Zealand, one of the tandem guys referred to my bike as the "funny bike". I resisted laughing when we passed him on the 10-16% grades in the mountains. Oh...he never commented again after we passed him.

Todd,
Just wanted to let you know that I returned from my two week 818 mile trip in the Alps of France and that I was very pleased with the bike!
Thanks,
Mark G.

My wife and I have about 500 miles on our new 10th Anniversary edition Joint Venture and I just wanted to write and thank you for building such a wonderful machine. I have not had tandems before but we test rode quite a few before buying. This bike just rides like a dream. I can not believe how comfortable it is in all aspects. I don't know if its the rims, the tires, the frame, or just the whole combo but it's just really fun to ride. I have a Merlin Extralight for my single and I think the da Vinci is way more comfortable. So anyway, I just wanted to say thanks.

Bob in SoCal

Brian--

I love all my bikes, but only one is a marriage machine. We have had some great times on that thing, from the MS150’s, to 2 weeks in Italy, to Sunday morning cruises to the coffee shop. It may be one of the more expensive bikes made, but it was a great investment in the most important relationship in our family or any other.

Keep up the great work,

Todd & Brian,

Vicki and I have now ridden the initial 100 miles on our Joint Venture this Montana November. What a joy to ride it has been! The level of workmanship and functionality is remarkable. A friend who has over 100,000 miles on his tandem is now seriously considering a da Vinci Designs tandem after examining our new ride.

Lionel

Hi guys, just wanted to let you know our bike came, and we love it! I'm really impressed with this whole experience of buying a tandem from your company.You helped us choose the perfect bike and it turn out exactly that way.The high quality and workmanship shines through this bike, and we can feel it while riding down the road. Turns alot of heads too. You guys even take your packing serious, that's the best packing job I've seen. thanks for such a beautiful bike, Bonnie and Chuck ps...maybe we'll see you in Tucson this nov.

We’re in our 3rd season on our global joint venture. It had its maiden global venture this spring – 2 weeks in Italy. I had worried a bit about flying with it in these days of heightened security – how much unpacking would they do? — but it was no problem. Among other places, we spent 4 days in Pistoia and saw the finish of a stage of the Giro D’Italia there. We rode part of the race course as well as exploring the steep olive groves and vineyards on other roads high above the town. The bike was just fantastic on the long climbs and steep technical descents. I’m very glad we got the rear disc brake. And the steel frame ride was almost buttery over the narrow cobblestone city streets. It got almost as many admiring looks and close inspections from the bicycle-loving Italians as my wife. The bike remains our most prized possession and possibly the best “marriage machine” ever made.
J.C.

Tamara and I thoroughly enjoy our Joint Adventure tandem. We are 100% certain that the Independent Drive was the correct choice. On a long ride it is very convenient to stand off the seat to rest your bottom while the other rider pedals. We have also been trying to improve our climbing by getting the pedals 90 degrees out of synch on the steeper hills and it does seem to help the perceived pedal effort.

Again, thanks for the great bike. We have received a lot of complements on the bike and on the quality of the bike components from other riders.

Mike R.

Todd & Brian:

I'm sure you hear this all the time, but thank you for building my beautiful bike. It's more than I imagined. I appreciate your great attention to detail and insistance on perfection.

Andrea

I have a da Vinci Joint Venture that I bought from it's previous owner. He had the bike for a year and liked it so much that he had another one built for him and his wife with a few custom alterations. I wasn't able to take it out of the box for a year because I was mobilized on military duty. Anyway, I'm back home and I have been riding it for the last three months and I love it!

Thank you,
Patrick K.

We bought a tandem in November and think it's a wonderful bike... This tandem is a GREAT design and we simply challenge anyone who has ridden a conventional tandem (as we had) to try the Da Vinci and not be blown away by the many advantages and comfort.

I ride the tandem all the time around town, with either my wife or daughter on the back. It's so easy to maneuver compared to a conventional tandem.

We also rode 540 miles in six days down the coast of Florida, from around Jacksonville to Miami, in December. We were loaded with about 70 pounds of gear...and this tandem rode just great! Had we been really touring I have no doubt the tandem could have been completely loaded up and perform great.

We used fatter than average tires which the 26 inch wheel makes easy, and enjoyed a very smooth ride. Halfway down the Florida coast, we hit a thick four-inch nail that went through the rear Contiental 1.75 Top Touring tire we had in the rear, and shot out at the edge of your great, no-tools-required-to-change-the-tire/tube-36-spoke, V-22 rim. (Or the nail when in at the side of the tire/rim, and shot out the top...who knows!) The nail caused an instant lost of tire pressure, which we really enjoyed as we bounced off a large concrete curb with a competely flat rear tire, effectively riding the rim. The nail also cut a small gouge into the aluminium of the rim sidewall. While I should probably replace that rim in the near future, the wheel itself remained completely true, and the trip continued on without any problems!

I have lots of pictures of the ride, and I've attached two to this email...one shows what all long rides need, especially in the middle of the day: a Coke, and a German Hefe-Weiss!...

Further to our conversation at interbike… here’s some pictures that you might be interested in…. Our holliday was awesome and the bike worked flawlessly…. The bike is a marvelous piece of equipment, we want to thank you for making such memories possible for Austin (the Auz) and I…

We are extremely happy. We talk up da Vinci tandems like parents talk about their first born child. We tell every couple we see how this is the only way to ride. We tell single men that owning a da Vinci tandem would be a great indicator to single women that they are not afraid of making a commitment to a quality relationship. We laugh at tandem teams that have a frowning stoker, or the captain stooped over in a grimace. Heck I could go on and on but you get the idea.
Alan H.

One of the ego-boosting games that we play with the daVinci is called "hunting roadies".

The necessary ingredients are tall gears, a long gradual downslope and young, unsuspecting, single bike wannabe road racers. We have a favorite place on the US Air Force Academy especially suited for the sport - about four miles of nearly constant grade that drops almost 500 feet from start to finish. It's a great way to end a training ride when you can make it happen...

The scenario: Two older, somewhat chunky riders on a 26 inch wheeled tandem, sitting quite upright because of the captain's moustache bars and stoker's upswept MTB bars, clad in nondescript unmatching t-shirts and faded cycling shorts, leisurely approach the beginning of the kill zone, waiting patiently for an overtaking road bike rider. As the roadie passes, the tandem offers a friendly greeting. If the greeting's returned, the victim goes free. But if all you get for your greeting is a disdainful glance, the hunt is on. Slow acceleration (this is a tandem, after all) puts you on the victim's wheel in no time, where you linger long enough so that the poor soul feels the pressure and accelerates to drop you. Thus the gauntlet is thrown down. Now it's time for the captain to drop down into the aero bars that sit atop the moustache bars, and the stoker drops her elbows onto the tops of her MTB bars with her arms extending forward around the captain's hips (some may recognize this as the Pam Blalock Tuck). Now aerodynamically configured, the stealthy tandem pops up into the 60/11 big gear and starts to crank, popping out of the draft to pass while politely offering the hapless roadie a tow if they want one. The competitive roadies will hop on your wheel, intending to suck wheel for a moment so they can blast past to humiliate this insolent tandem pretender, but the speed keeps increasing. And the roadie's cadence keeps increasing. And the speed keeps increasing. And there's not much draft behind this aero tandem. And the tandem's still spinning as we go past 35 miles per hour (remember, this is still slightly, deceptively, downhill). And the roadie's REALLY spinning. And almost none of them can hold the wheel, simply because they've spun out their top gear... So you continue to push hard so that you can rationalize your spiteful performance as merely the end of a hard training ride, and soon the roadie's out of sight (older tandemists have bad eyesight, you know).

The end of ride kiss for your stoker somehow tastes just a little sweeter, and she has this silly grin on her face... Competitive? No way!...

Jon and Ann M.

And if the roadie rejoins you later at the end of the ride in the parking lot where most riders congregate, they're always talkative, but usually just want to have a closer look at the tandem, not the tandem crew...

I would echo and agree with Kurt Anderson's comments on the S&S daVinci. We did find the independent coasting feature to be an important point in our decision to buy it. We tend to spin rather than climb out of the saddle, and find that climbing out of phase on long climbs works well for us. It it very simple, as Kurt mentioned, to get back in phase . There is a learning curve, but not a difficult transition, we found.It seems to combine the best features of tandeming with the "feel" of a single bike. It handles very well, is comfortable to ride, and the slight extra weight of the drivetrain is cancelled out by the 26" wheels and frame design, I believe. We are a 375# team and have had no problems at all with pinch flats or spoke breakage like we did on the 700cc-wheeled Trek. Wide choice/availability of tires, 32 real usable gears and etc etc. The "large/small" frame fits us both (6'5 me & 5'7 Cheri, and her 9 year old daughter can also stoke with the seat lowered and using crank shorteners.) We've flown with it 3 times so far, it is relatively easy to take apart and reassemble, and goes well into the 2 hard cases we bought. It takes us about an hour to take it apart and about that long to reassemble it. ( I have a Bike Friday single so perhaps was less intimidated by taking apart an expensive bike and putting it into a suitcase) No airline hassles at all, so far! We have "upgraded" to the campy veloce system on our In2uition, and also have the deep-V rims/White hubs. Both are good choices, particularly the wheels which are fitted for a disc brake should you want one.Do try to ride one...Cheri refused to go back to the other bike once we rode the daVinci.

Wanted to let you know how much we love our new Da Vinci Joint Venture. We have had it out on the road a half dozen times up to 25 miiles. We're still in the process of doing minor adjustments to seats and handlebars. Over all we are very pleased with how quickly we adapted to a tamdem ride. The independent coasting is superb and the gear range is wonderful. We are doing well as a team and enjoying the experience.
Thanks for a super machine.

If you have a potential customer in our area who would like to see a Da Vinci feel free to give them our name and phone #. We would be happy to show it. Terry & Linda K.

Todd, just a short note of thanks for the great job you did on my bike. I noticed it on the internet and must say it is a work of art. I have been riding bikes since I was knee-high to a grasshopper and untill recently never had the money to buy the bike of my dreams. Well as life turned out I came into a position to get my dream bike. As you are well aware I had some definite thoughts on what this bike should be. Through my constant conversations with you ; where I would have a strong preference for a component (the handlebar stem for example), you would enlighten me as to the pros and cons of the part in question. I was also made aware of other concerns that come into play when a custom bike is being created. Through this process where I would request to you a thought or Idea as to what I wanted you would turn that thought or Idea into reality. The end result of this process was a creation of something more than mere machinery. To glide thru your environment on something so smooth that you feel no concerns has to be a touch of true freedom. Ride On

We hit the first 500 miles on the new bike it is great! We really like it. We did a ride last week with some good hills and the gearing is fantastic. We have meant to let you know sooner how pleased we have been, but our schedules have been hectic and our first priority has been to get our rides in. Next week we head to the Hotter Than Hell. We will hook up with Richard and will be glad to chat with anyone interested. I think my boss is going to want to get the samething we did, when his life finally slows down. He was impressed with how we out performed he and his wife (and I don't think we are that tough a team!) We will also be hanging around at the time trials the have at Moriarity over Labor Day Weekend.
Let us know what we can do to help promote this product:)

After years of dreaming and planning we left our home in Vancouver, Washington on September 10, 2000, and pointed our da Vinci Global Venture west along the Columbia River to the Pacific coast at Astoria, Oregon. Nearly a year later on September 1, 2001, we returned. Along the way we rode 15,000 miles around the perimeter of the USA, with side trips to Mexico, the western Caribbean and the Canadian Maritimes. The total distance including travel on trains, busses, autos and a cruise ship was a little over 20,000 miles.

Our plan to be self-supported the entire trip, sometimes hundreds of miles from the nearest bike shop, or for that matter, the nearest anything, meant the right bike would be critical. We test rode many makes and models, eventually choosing the S&S Coupled da Vinci.

Our tour was a 100% success. We went everywhere and did everything we planned. We were exactly on schedule all the way. We had zero sick or injury days, and thanks to the dependability of the da Vinci, mechanical issues were so minor that our total "breakdown time" for the entire year was less than 3 hours, and we were NEVER stranded alongside the road.

One issue we spent many hours on was what to bring on such a long tour. We had to balance weight and volume while trying to make our bike "home" for a full year. Ultimately creature comforts won out. We loaded four panniers, trunk, handlebar bag and packed the Bob trailer a little over it's seventy pound Max weight limit, which included a lightweight folding "loveseat" ( gotta allow some considerations for the stoker)! And no, we did not send a bunch of gear home after the first climb.

Speaking of climbs -- we made them all. Total walking miles for the trip -- zero! The wide range of gears and the IPS on the da Vinci got us up the long, high climbs in the West and over the 13% grades of the Northeast. IPS allows us to quickly change from in-phase to out-of-phase pedaling, depending on conditions. Also, we change pedal positions slightly, allowing the stoker to either lead or follow the captain's pedal stroke a few degrees, changing the load-share. Contrary to what most tandem teams believe, IPS is not a "beginner's" item that simply allows easier starts. It does allow easier starts, but taking full advantage of IPS adds another dimension to the da Vinci.

Handling the da Vinci fully loaded was a lot easier than it looked. At nearly 14 feet in length and covered with panniers, we were asked time after time if a commercial operators licensee was required. Low speed handling is solid and eventually we learned to do brief "track stands" for stop signs. On the other end of the spectrum, our top speed was 58 MPH on Highway 101 coming down the long grade south of Willits, California. We rode on every type of surface imaginable, including several brief stints on gravel/dirt. The chrom-moly frame gives just the right amount of relief from road shock, but doesn't flex when we both stand for steep climbs. Yes, that is correct, the handling of the da Vinci allows us both to stand, even when fully loaded and towing a trailer.

Our only disappointment for the entire trip was that it ended. The good news is that we are already well under way with plans for our next tour!

I got a da Vinci tandem so my teenage daughter and I could bike together. I watched friends lose touch with their kids as the kids struggled through their teen years and was determined not to let it happen to us. The tandem is ten times better than a therapy couch, and probably a lot cheaper in the long run. We may start out silent, but over the course of a 30-mile ride we always talk. We talk about school, boys, parties, health, college plans. We even talk about my job, my frustrations, what it was like when I was a teen. Sometimes we ride longer than we planned because we want to keep talking. Riding the tandem and talking is much better than sitting face-to-face and talking. On the tandem we’re a team. We’re working together to get somewhere. We are not adversaries, and we know that we need each other to get home. Do we have our struggles? Of course. But our da Vinci tandem is a great way to bring the two of us together.

Dear All,

Judy and I have been a tandem team for several seasons, and looked forward to this season with great anticipation. Our first tandem, a KHS Tandemania Roma was better than we'd expected, and got us hooked on the sport. It was replaced last year by our light and oh-so-portable Bike Friday XL - we'd planned on doing a few trips this year.

But as they say, life is what happens while you're busy making other plans. Judy, who wasn't overweight ate right, never smoked, never drank, good family history, etc was an unlikely candidate for health problems.
Ironically, early this spring something (probably a virus) attacked her heart and created a very severe, and potentially permanent, problem. As one consequence, while she's advised to get 30 minutes of light exercise every day, hard efforts must be avoided, and she has to stop at the first hint of fatigue or shortness of breath. To make the long story short, we decided to acquire a DaVinci because independent coasting would allow her to stop pedaling entirely and rest as needed. So two months ago I called Todd Shusterman and ordered an aluminum DaVinci "Joint Venture" road tandem.

I did so with some trepidation. Pros and cons about in or out-of-phase pedaling and independent coasting are common on this news group. One recent contributor wondered if a turn with the wrong pedal down might even
precipitate result in a crash. But circumstances rendered the arguments moot. Basically, independent coasting was mandatory if we were to keep riding.

The bike (since dubbed "Sophie" because she is one "sophisticated lady") arrived a few weeks ago. As expected in a bike at this level, the quality is impeccable from welds to components and paint. After a short assembly
process, the bike was pretty much dialed-in. I invited Judy to go on a quick shakedown cruise around the block. No bike shorts, jerseys or cycling shoes; just helmets, gloves, street clothes and sneakers.

Down the driveway and out of our cul-de-sac we went. I then checked for traffic and executed a quick right turn onto the nearby cross street. A few seconds after the turn, a startled "Oh!" emanated from my stoker, followed
by a laugh and an explanation; "When we got to that corner, I stopped pedaling, but you didn't!" I hadn't even noticed. I just did what is normal for me, which is to keep spinning, and Judy had done what felt normal for
her, which is to coast through the corner.

We pedaled around the neighborhood for another ten minutes checking things out and made a quick game out of "Hey, can you tell when I do 'this'?" Truth is, the independent coasting system was all but invisible. We both
started and stopped pedaling whenever we wished. It was smooth, stable and required no getting used to.

Next day we went on our first 20+ miler of the year. It included a relatively easy 2-mile hill; up which I spun. Yes, when Judy stopped pedaling I noticed that the hill got a tiny bit steeper. And if she took some air time to shake her bootie, I'd feel it, just as I would on any tandem - but I could keep right on pedaling. With the stoker out of sight, I pretty much forgot about the independent coasting, and just got on with riding. And hey, *I* could stop pedaling without upsetting the apple cart either. Veeeery nice.

We've put on a few hundred miles since then. In some out-of-phase situations, particularly high rpm, we notice a very slight wobbling-bobbling sensation. Whether this is an integral characteristic of out of phase pedaling, a function of pedaling style, or a combination I cannot say. But such instances have been rare and short-lived. Getting back in phase is effortless for us. In fact, we seem to ride in-phase (or roughly so) more often than not without conscious effort.

A good friend, who frequents this list, found that independent coasting didn't work well for his team. In particular, his stoker reported missing the feedback and communication through the pedals. Our experience is the
opposite. Surprisingly, we feel *more* in-sync. I hypothesize that our communication is more body-english related, which perhaps explains why falling into phase seems natural.

We haven't tried out-of-saddle climbing yet - there's been little call, and Judy always preferred seated climbing in any event and I'd made that accommodation early on in our tandem experience. But we've tackled several
fairly hard hills - one at 8-10% for a half mile or so. Judy was, as hoped, able to stop pedaling. Due in no small part to the DaVinci's incredibly wide gearing I was able to tow us up without difficulty. Slow? You betcha.
But a lot faster than sitting at the bottom. The hardest part is that Judy doesn't like just sitting there while I do all the work (or so she says :-)

As an aside, we ordered the DaVinci with the optional Thudbuster post. Judy *loves* it - reporting it to be *much* better than the vertical compression post it replaced. It's so much better I don't even bother calling out any but the largest bumps and ruts anymore. Big kudos.

Bottom line: if you're in the market for a high-end bike, do yourself a favor and test-ride a DaVinci. It has the look, feel, low weight, and responsiveness expected of a bike in this price range. Independent coasting
may not work for everyone. Just don't be surprised if it makes you feel even more "in-synch" than having your pedals locked together.

Best,

Chris Rutkowski

We just acquired our second DaVinci--an aluminum  Joint Adventure--and everything
you say about it is true. (The first is a coupled Global Adventure.)

The independent coasting solved a lot of problems Tony and I had had on our
conventional tandem, and the ride quality and handling are wonderful. I especially
like the 26" wheels and tires, which along with the Thudbuster absorb so much road
shock but are so light. The gearing and shifting are a dream, though as stoker, I
don't do much beyond lightening up my stroke to facilitate a shift under load now
and then.

I agree. Throw away all your preconceptions and give a DaVinci a chance. If you're
not sure after a few minutes (we knew we wanted one within about two), give it
more of a chance. I daresay we couldn't go back to a conventional tandem now.

Sarah

P.S. It's also a great conversation piece, especially if you encounter someone who
knows tandems and spots your drivetrain.

Todd- Hats off to you from the guys at Ti Cycles (and myself!). That is one sweet, fast bike! After breaking a few speed limits on the 200k last weekend I have to say that I am a very happy customer! The bike handles well, goes like a bat out of hell (especially when someone tries to slide by us on the flats or better yet on a slight downhill). I have slipped into the 64x12 and taken off a number of times and since we greased up the squeak in the beam we slip right by the rest of the pack on those occasions. I call it my stealth gear!

Cheers!
Linda

Subject: WOW!

We picked up the new Global Venture from Gateway Bicycles yesterday. It is beautiful! Exactly as ordered. We were impressed that all the equipment was just what we asked for. Jonathan and Mike were very helpful all the way through the process. Even though their shop was a "zoo" yesterday first really beautiful spring Saturday this season), they made sure we were set up and ready when we left. This is the second tandem someone in our family has purchased at Gateway, and won't be the last.

We took a short spin around the neighborhood as soon as we got the bike home yesterday afternoon and ran into an immediate problem -- we got stopped every couple of blocks by someone that wanted to look at the bike! Lots of great comments about how cool it looks! Hopefully, this won't happen too much on our 20,000 mile tour of the USA, Canada and Mexico that starts September 9th. We have allowed ample time for the tour, but showing off the bike was not a factor we though we would have to allow for!

Great job on the bike and thanks again for all your help and advice,

George and Sharon Miner

Ps: We'll keep you posted as we get closer to the start of "Free as the Wind," our unsupported 20,000 mile tour around the perimeter of the USA and include you on our email list for updates as the ride progresses.

We recently ended a nearly 2-year long search for the perfect tandem for us and chose the daVinci Symbiosis XC.  Along the way we had the opportunity to test ride a number of tandems.  IMO buying what feels good to you after a
short test ride is not the way to go.  Talk to experienced tandem riders about what is important and start from there.  We were in the Bay area last year and had a great opportunity to talk to folks and test ride a number of different tandems incl. Santana, Co-Motion, Burley, Cannondale, and daVinci. Breakaway Bicycles in Dublin, CA let us have a C'dale tandem for a weekend. Never having owned a tandem before, this was an important experience for us. We needed to know if the kind of riding we thought we wanted to do could be accomplished on the kind of tandem we thought we wanted.  It couldn't.  The tandem we finally decided upon was completely different.  The extended test ride made the difference.

Our conclusions at the end of all of this test riding:
1) The geometry of Santana frames makes their bikes very stable.  To novice tandemists taking the bike out on a 20 minute test ride with the driver getting used to the long wheel base and the shifting, and the guy/gal-in-back ("GIB") feeling out of control, Santanas feel good and give you confidence.  However, after the experience acquired from riding over 100 miles together, the stable ride begins to feel like you are driving a truck. You long for something with quicker handling.
2) Santana charges a premium price.
3) The component package does not measure up to the premium price.
4) Santana does not offer a feature we found to be very important - an independent coasting system.

Some thoughts on what tandem buyers should consider:
1) Stoker comfort!!!  We went with the Thud-buster suspension seatpost, steel frame and independent coasting driveline.  No matter how much you pay for your tandem, if your stoker is not comfortable, the bike will sit unused.
2) Front suspension/bigger tires - Even if you plan on road riding exclusively, let's face it, life on the shoulder can be hazardous.  On a tandem, you have much less opportunity to avoid potholes, glass, gravel and your occasional construction zone.
3) Gear range - with experience you will find you want as wide a range as possible.
4) Handling - stability gets boring after a while.
5) At least the capability of doing double-track off-road.  We consider ourselves "Roadies" but when the road comes to an end, we can still explore.
6) 26" wheels for strength and wide variety of tires.
7) Frame size and design that can accommodate a wider range of driver height.  GIB should have opportunity to drive sometimes and driver should be able to discover the joys of stoking.  As the guy who usually drives, I find it to be a nice change of pace to have my girlfriend drive so that I can relax and enjoy the scenery.  She prefers stoking, but occasionally likes to experience the advantages of driving.
8) Independent coasting driveline - we find this a great help!  It eliminates 80% of what we find uncomfortable about tandeming.
a) No more communication like, "My butt is getting sore, can we coast for awhile so I can stand?"  Either one of you can coast at any time.
b) No shock to the knees if the other stops pedaling unexpectedly.
c) In-phase/out-of-phase - you can change on the fly.
d) Momentum can be maintained even when one of you has to stop pedaling.
e) When clearing curbs, logs, or other obstacles, sometimes the driver has to stop pedaling for clearance.  The GIB can still power you over the obstacle.  Then when the GIB has to clear, the driver can be pedaling.
f) Starting made easier.  The GIB can power the bike while driver is clipping in.
g) Driver has much better control during stopping and close maneuvering.
h) We have a 32-speed driveline with the equivalent of a 60-11 high-end and a 24-30 low-end.

We found that for us daVinci Designs has the superior product.  Your own extensive test riding and research may find a bike that better fits your needs.

Our dream bike is finally here!

Background:
Last spring, I helped my friend David's parents buy him a wedding  present: an S&S Softride bike from CoMotion.  This was nearly the same bike as the stock SkyCapp they now sell, with a few upgrades.  Naturally, I was jealous, and resolved that Amy and I also would have such a bike ASAP! When I got some money around Christmas time, I knew we could buy.
I've heard from enough people with beams to gather that beams have rivals, but no equals, for a smooth ride.  In January, I noticed that Todd Shusterman from DaVinci had been asking for comparisons between beams and parallelogram suspension seatposts.  I correctly surmised he was toying with the idea of building a beamed bike. As I have always been intrigued by his drive system, I talked him into making a beamed Joint Venture for us.

The bike:
This bike has DaVinci's top-flight component set, on a frame Todd designed specifically for the beam (and, in our case, our *wildly* different heights; the rear top tube is about parallel with the lateral tube).  You can see the stock version at DaVinci's website. Our rear seatpost tube is functional if you remove the beam, which can allow very small riders on the back.  Perhaps larger ones, too -- Todd  mentioned he did the test rides with a seatpost in.  DaVinci made a plug for the seatpost tube when it's not in use. I didn't know DaVinci does this, but I was pleased to see that they ovalized the boom tube up to the coupler.  Also, the small size in back dictated (at least to Todd's perfectionist mind) a monostay.  The beam rests on a straight tube, rather than the angled tubes on beamed CoMotions and Burleys.  Overall, the frame design is very trick. To help make up for our height difference, we got 160mm crank arms in back, and 175mm in front.  I added BeBop pedals, and am trying to buy a rack to fit the bike from Bob Beckman's Needleworks company.

Riding:
This bike rides beautifully for us.  We've spent some time on a stock Burley that totally didn't fit us, and my friend Dave's beamed CoMotion, which doesn't really fit us.  The Burley was awful, and the CoMotion was pretty good, but not like our DaVinci.  On our first ride, I hadn't checked the tire pressure, so I thought the bike felt so solid because the tires were low.  But after overinflating them by 30psi, the bike felt just as solid.  Amy has told me several times now to stop calling out bumps,
and I've had pretty instant confidence in low- and high-speed manoeuvres. Shifting and braking both feel perfect. Of course the main unusual feature of this bike is the independent coasting system (ICS).  We haven't spent a lot of hours on tandems, and I
purposely wanted to have the ICS from the beginning, in order to acclimate to it without prejudice.  We like it quite a bit.  For relative beginners, it makes starting much easier.  At the beginning of each ride, I find myself  having to remind Amy to get in sync, but after that she seems to have little trouble syncing up when she needs to. The ICS allows an extremely wide gear range, which we haven't yet exhausted on either end, despite doing some very steep hills.  Usually, of  course, you don't notice the ICS, though at times even the 175-160mm  crank-length difference was too small to keep me from outspinning Amy.

Glitches:
This being DaVinci's first beamed bike, they didn't know about quick-releases for the beam.  The folks at Softride were quite unhelpful to Todd.  Softride suggested that he have his customers bring a hammer with them on trips, to detach the beam by pushing the pin!  CoMotion was good enough to send me their clevis pin arrangement, and after drilling the quirky 4.4mm
hole to 3/16ths, I had a quick-release beam. The bike is very small in back, so the rear triangle doesn't fit anything inside.  The beam is very long, so you have to take the seat off of  it to shorten it.  All this makes it a little harder to pack in the S&S
backpack case, but you can do it.  On last week's visit to NYC, though, something heavy put a ding in our rear rim where it touched one of the tubes, and I'll probably have to replace it after the summer.  (Also, the rear derailer's mounting screw came out, and I had to use Vise-Grips to rotate it back in position.  I'll put a nut on there next time if I can.) Rare is the shoe that doesn't need to be trimmed when you use BeBop pedals.  We like the pedals, but I spent a lot of time prepping our shoes for
them with a utility knife.

Kudos:
Although not as pretty as CoMotion's famous paint jobs, DaVinci's powder coats are exceptionally tough -- especially important for a bike on an airplane.  I missed protecting some friction points on our NYC trip, but the rubbing didn't penetrate the paint. Also very handy for S&S bikes are DaVinci's cable splitters and easily removed cranks.  The cranksets are especially round, which makes for a nice tight timing chain (it also doesn't hurt that DaVinci's drive uses two shorter timing chains rather than one long one).  Cable housing and stops are  intelligently set up.  Because I don't have to adjust brakes, derailers or
eccentrics when I assemble the bike, it goes very quickly.  Todd passed on a good idea, BTW, for protecting the S&S coupler teeth on the airplane -- cut an "X" in old tennis balls and place them over the tube ends.

Recommendations:
I really like the ICS.  With that, couplers, and a beam, the bike is flawless.  Even without ICS it would be our bike of choice.  But if *you* don't want ICS, you'll be buying from some other manufacturer. I'm probably the only one on the mailing list who has bought two high-end bikes like this in the last year, and judging from my experiences with CoMotion, they would be an excellent choice as well.  Both CoMotion and  DaVinci were remarkably professional, friendly and responsive.  When
questions came up, or choices needed to be made, both called right away, and  took the time to explore the issues with me.  In general, of course, I think the whole tandem-building industry is like this -- I've had very friendly and  informative conversations with Green Gear and Santana as well. DaVinci's base bike is slightly nicer.  When I ordered my friend
David's bike from CoMotion, I ordered 175/160 DaVinci cranks and cable splitters, which made up most of the difference.  I would not want to do without cable splitters on a coupled bike! Neither of these bikes was cheap, and they're not in everybody's  price range.  Other manufacturers make beamed bikes, or S&S bikes, or bikes with both -- consider Bilenky, Burley, Erickson, Green Gear, Santana, and any of the other dedicated makers on the list.  I don't think you'll be able to
get bikes like these from Cannondale and their ilk, but I could be wrong. Based on my research, you tend to get what you pay for, in the sense that upgrading a bike from any given manufacturer to the rough equivalent of a bike from somebody else will cost you about the price of the hardware involved.  Nobody's getting rich off this stuff.  We are very happy with the
value of our DaVinci -- it's precisely the bike we want.

Bike On!

Well our new full suspension Symbiosis arrived Monday from daVinci.  What an incredible piece of machinery!  Top shelf goodies all around, like Hope hubs and disk brakes, Control Tech posts and stems, Fox shox in the back and a ravine eating Hanebrink fork in the front.  The fit and finish of the frame, cable guides, the daVinci cranks, paint, ect. would have made
Leonardo himself blush.  I am speechless.  The independent coasting driveline is a definite must for offroad work, allowing the tandem to clear things that would hang most bikes.  If you would like to view the finished masterpiece in all of its glory, I have enclosed an address which has a picture of our actual cycle.  http://teamspirit.net/sy.html

Dealing with Todd Shusterman and Eric Short has been a delight.  Todd's project management skills in pulling together the numerous suppliers and communicating with the client was impressive (and I do project management for a living!).  One of the factors that made the custom tandem experience so enjoyable was Todd and Eric's high level of customer service.  Any time
I had a question or suggestion Todd and Eric were very responsive, in most cases within several hours.  Both of these gentlemen understand the meaning of "Partnering" with the customer and every tandem that these guys build
has that custom tailored look and feel.  I would recommend daVinci to anyone.  Honestly, I told Todd that I would never by another mass produced cycle after seeing how well he fit me (at 6'7") and my wife (at 5'7").

If your in the market for a new tandem or if your looking to upgrade your components, give Todd a call.  He is an incredible craftsman and an outstanding resource for unbiased information.

Todd,
I wanted to share this little email exchange with you.  We have a local tandem club called TROL (Tandem Riders Of Longview) and we're planning a two day tandem trip here in East Texas in September.  The two people coordinating the
trip are Reggie Bowers and Michelle Callaway at where I work.  I really want to go on this trip but my stoker is unable to make a weekend trip.  It's hard when you and you're stoker are married, but not to each other as is our case.

My Joint Venture is performing great. It gets a lot of attention at races and we came in first again in a race this past Saturday.  I'm three for three on the Joint Venture.

Anyway, here is the office email that has my solution to participating in the tandem weekend getaway which follows Reggie's response.

Take care,

Bill K.

Todd:
        Cathy made it down to Portland today, hitched a ride to Gateway Bicycle and rode the medium-size Joint Venture with a great guy from the store staff....good weather meant they got to spend a lot of time on the bike....
    Well, she's sold, and then some!  She left me a phone message this afternoon and I talked to her "live" tonight on the phone from her hotel...she was still buzzing about the bike, the ride, and the shifting/gears....

Todd,

Thanks for your help and craftsmanship on building the "Purple Tiger" (It is very purple).  Your wheels are awesome.  I think you should put them on your Symbiosis.  Thanks again.

Hey y'all, Sound the trumpets!  Strike up the band!  It's official!  K.R. is now a CENTURION!  She completed 100 miles on the tandem with me today.  She really didn't need me, though. She could have done it easily by herself.  Our previous longest ride was 93 miles, but that was back in February.  She had knee surgery shortly after that ride so our previous long ride was 63 miles in Mt. Pleasant two weeks ago.  By the way, today was 6 weeks since her knee surgery.

We rode the new 1998 Rubicon century route today on the fantabulous DaVinci Joint Venture tandem.  What a machine.  It's wonderful.  I've noticed it gets considerable attention from other tandemists at rides.  Rightly so. It's a dream machine.

etc... Century recap

Hi Todd

Elizabeth and I took our new bike out on a 50 mile inaugural ride yesterday.  We were impressed with the bike and enjoyed the ride greatly.

It took us a little while to get used to the independent coasting - we found riding out of phase quite uncomfortable. Fortunately we found it quite easy to get into phase - you don't even have to look or count, it just feels "right" to start peddaling at one point in the other rider's cycle.  Once we had this mastered the ride was far more comfortable, and we could appreciate the benefits of independent coasting - more control when riding slowly alongside traffic, no lost momentum when the
pedaling stops for the captain to get into clipless pedals/into toe-clips, random breathers etc. etc.

The bike feels more like a single than other tandems I have riden and we ended up pushing up the steeper hills rather harder and faster than we would have done in the past - the net effect was that we were more tired at the end of the ride than we expected.  The bike may be the best hill-climber we've ridden but I think we'll need to be fitter to get the full benefit!

I am fascinated with bicycle technology.  I tried your road bike and like it very much.  I have a whole raft of tandems including a custom Serotta titanium, but I prefer the da Vinci on most all rides on which I use the upright.  I have ordered a recumbent Screamer from Kelvin at Angletech and am going to have the da Vinci IC system installed - try to talk Kelvin into using your cranks - I find them very nice.

One thing that I have had to do is raise the stem - because of back pain.  This is not a problem of the bike - only the rider.  I added a stem extender (Zoom 50mm).  Would it be possible to manufacture another fork with the appropriate height so that I would not have to use the extender?  I would be happy to exchange the one I have and include any costs you thought were appropriate.

Everything you say about IC is true.  My wife and I find it very easy to manipulate the pedal angle to suit our riding needs.  I find that the bike climbs very well.  One thing that your system provides is an outstanding range of gearing.  I find that I can smoothly transition to an appropriate gear ratio without having to drop too low or go too high.  For a recumbent this will be a very powerful tool.  Everybody I have shown it to around here including Eastern Tandem rally and GEAR is very impressed.

My friends think you must be a aircraft engineer by the way you designed the clearance of the pedals!!

Mark,
Your note asking for info about the DaVinci Joint Venture was forwarded to me from a friend.

I own a DaVinci Joint Venture and love it!  I ordered mine last October from Todd Shusterman at DaVinci (he builds them) and had it customized for me. It's a dream to ride. It has a ton of gears....four chainrings and 8 in the rear cluster for a total of 32 gears.  My biggest chainring is a 64 (actually a 32 on the DaVinci but is the same as a 64).  I have thought about putting a
68 on the Joint Venture because I occasionally run out of gear on the high end.  I have ridden the heck out of it since I got it and have had no problems whatsoever.  The only problem I had, and it's minor, is that it came with Richey Tom Slick tires and I was flatting very often. I changed to Contintental Grand Prix tires and have not had a single flat since (oops, I shouldn't say that!).

The independent coasting is fantastic. I ride with multiple stokers and most have said they would never ride with me without the independent coasting feature.  Riding in synch or out of synch is not a problem.  We tend to ride in synch on flats and downhills but my stokers will pedal 90 degrees off so their power stroke is on my weak stroke when climbing hills.

I can't say enough about the DaVinci.  I like the 26-inch wheels and I think they make better sense for a tandem.  Todd is always available for questions either on the phone or via email. They have a great website which I'm sure you've visited.

I'll be happy to answer any questions you have about the Joint Venture.  I love mine. It's a highly crafted tandem and total fun to ride for the captain or stoker.

Bill
