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.
Both Stiffys are available with Standard Spacers to fit most cantilever brakes or V Spacers for use with Shimano V-Brakes.
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.
