If you have changed, i am curious to know why and how it is working for you. I am thinking of doing it as I have a set of IRD canti's that are soooo easy to setup and brake really nice. Current v-brakes are cheapies and hate the clanky adjustments. Buying a nice set does not seem practical if I have these canti's to use. Plus can also use my old school Tech-lite brake levers. Could be a nice setup since cash is tight. What would you guys do? Or is this too backwards?
