I have been searching past threads on this, and all I seem to find is the levers are not compatible. So my ? is. Is it worth the time and effort to go from cantilever brakes to V brakes. Is there really that big of a difference in stopping power? Just to add, the bike I am thinking about doing the upgrade on is a 96 Fisher with Alivio cantilevers and replace them with newer Tekpro V's or is it just a matter of having good pads?
