Here's the situation: my '92 Ritchey P-22 comes with Deore XT 3x7 brake-shift levers and XT cantis. I don't like the performance of the cantis, so I'd like to switch to XT v-brakes. Now I know that the brake levers won't be compatible anymore. What should I do? In a perfect world, I'd like to change for parts of the same weight or lighter.
