Anyone with experience with both cantis and V-brakes? Converting the 'cross bike to a townie bike with flat handlebars, and was pondering brake choices. I have flat-bar levers for both cantis and linear-pull brakes, and cheapo cantis already mounted. I really dislike the cantis, but was wondering if switching to V-brakes will make much of a difference in stopping power, ease of set-up etc? Any other choices that mount on canti mounting pegs?
