If you have ever spent time on a tandem, perhaps you, too, thought the ability to coast independently would significantly improve
your ride. It is an idea whose time has long been coming. That's why da
Vinci Designs is excited to offer quality handbuilt tandems that showcase
the Independent Drive, an intermediate shaft that allows the captain and stoker
the freedom to coast independently of each other.
Our Guarantee - If
you do not feel the independent coasting is the best thing you have ever
experienced on a tandem, we will lock it out. You will still get all the
other benefits of the Independent Drive - wider range of gears, improved
front shifting, and higher ground clearance, and you can switch it back in the future.
To date, we have had one customer take us up on this offer.
“The design fixes all inherent problems with tandems.” The response of everyone who rode the Independent Drive™
tandem was unanimous -
“This will change the way tandems are made forever.”
Richard Cunningham - Mountain Bike Action “I wouldn't buy a tandem without it, having ridden
this.” Mark Langton - Mountain Biking “You've answered a question people should have
been asking. Very clean... Can we ride it some more?” Greg Shepherd
- Tandem Magazine “Wow! I could get used to this... intriguing.”
Rob Templin - Burley - RAAM Record
Independent Coasting... The ability to coast independently makes riding a tandem
far more natural and enjoyable for both the new enthusiast and the veteran
cyclist.
Wider Range of Gears... It is not uncommon to spin out even the highest gears
on a tandem, but you need those lower gears for climbing! Problem solved
- the Independent Drive mechanism doubles the range of the front chainrings
which gives even the most aggressive tandem duo all the gears they need.
With four front gears and eight in the back, you have a total of 32 possible
combinations.
Improved Front Shifting... The smooth transition of a narrow six tooth gap of the
four Hyperglide front driving gears found equipped on da Vinci tandems
eliminates the clumsy front shifting on conventional tandems with a minimum
twelve tooth gap.
Higher Ground Clearance... The raised location of the intermediate shaft and smaller
driving gears greatly reduces the risk of snapping the cross-over chain
or bending chainrings. So go ahead and take the da Vinci tandem anywhere!
No Hassle Child Adapter... The Independent Drive allows the use of a child adapter
without the heavy, complicated layout of additional cranks, chainrings, and chain.
Simple and Efficient Design... For years of trouble-free riding.
da Vinci Designs - Drawing outside the chalkboard... With a commitment to design function over normality,
we take a "drawing outside the chalkboard" approach to designing and specing
our tandems. The end result is a bike that is stiff, light, comfortable,
responsive, shifts like a single bike, has a range of gears all tandem
teams dream of, and you can each coast when you please.
Using proven geometry and the highest quality hand picked
tubes, we are confident that our frames rate with the best high end tandems
in the industry. We have hand selected every component on the bike for
strength, function, and weight.
