About 5 years ago, I put drop bars, bar ends and appropriate shifters on a Cannondale Caad2 MTB. Kept the Avid cantilever brakes. While the front brake was perfect the rear was mushy in the extreme. I used aero brake levers (Shimanos?) designed for this but was less than impressed with the results in the rear. Need to have better mechanical advantage at the lever or change the brakes. Anyone else do something similar or have suggestions on how to get a decent back brake out of this set-up?
