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.

When is the best not good enough?
Even though we offer a wider range of gears than any other bicycle in the industry, we occasionally have a need for gearing a little lower. The Campagnolo rear derailleurs we have been using for years do not work well with rear cogs larger than 29 tooth. We do not want to give up the reliability, rebuildabilty, comfort and front derailleur trim that only Campy Ergo shifters offer, but ten speed chains are proving to be too finicky and not very durable. Keeping to our Credo of "Drawing outside the chalkboard" we modified SRAM X9 Long cage and Medium cage derailleurs to work with Campy shifters. Now you can use any Campagnolo ten speed Ergo shifter and SRAM or Shimano compatible 9 speed cassette together. The CNC machined aluminum cable guide replaces the plastic one on the back of every X9 or X7 derailleur.

Available models:
C0-9
Campagnolo 10 Speed Shifters and Shimano/SRAM 9 speed Cassette.
C0-0 Campagnolo 10 Speed Shifters and Shimano/SRAM 10 speed Cassette.
S0-9 Shimano 10 Speed Shifter and Shimano/SRAM 9 speed Cassette.

Long Cage - Max rear cog 34 tooth - Chain wrap 45 tooth
Medium Cage - Max rear cog 34 tooth - Chain wrap 37 tooth.
