V brakes on old Cannondale - Will it kill the frame?
I picked up an early ninties Cannondale hybrid for my wife today. I'd like to replace the cantis with some v brakes from my parts stash. Will the higher mechanical force of v's cause the frame undue stress?
V-brakes don't actually provide more force at the pads than do cantilever brakes. What you are thinking of is the higher mechanical advantage of the arms themselves. To compensate for the increased mechanical advantage of the brake, the mechanical advantage of the lever is decreased.
Long story short, there isn't any brake out there that can really break your frame. Magura Hydraulic cantilevers might crush a rim, but that's as close as you can get.
Rather than replace my levers when switching from cantilevers to V-brakes, I first tried Problem Solvers Travel Agents. Don't--they are terrible. A pain to install, they kink the cable, and give terrible feel.
