Stress Analysis Designed Brake Stiffener – Use Your Energy to Stop – Not to Flex Your Frame
Improves your braking
Reduced “mushy” feeling at your brake levers
Reduce brake squeal

• We spent several tedious months on the design of these brake boosters. Trial and error with sophisticated stress analysis software — shaving a few grams here, adding a few grams there, until we came up with the ultimate design of stiffness and light weight.
• Brake stud spacing range 70 to 92mm (2-3/4″ to 3-5/8″)
• Big Stiffy (62 grams) for tires over 1.4″. The stiffest big tire brake booster we have experienced. It’s not the lightest, but are you looking for a piece of jewelry for your bike or something to improve your braking?
• Small Stiffy (47 grams) for tires up to 1.4″. The Stiffest & Lightest brake booster around. If you are running skinny tires, there is no other choice.

Retail Price $32  *** We are out of the stand-off hardware, but still have the braces in the photo above. If you would like to use your own hardware, we are selling the braces for 50% ***

Easy-Split Replacement Hardware
It is a good idea to replace your set screws when you replace the cables, or with the 2nd time you replace the cables. Only use a good sharp 2mm Allen wrench (Hex key) to reduce your chances of rounding out the set screw.
