What do I need to make it play nicely with Campagnolo parts?
easiest, Use all Campagnolo parts , sell all the other components , strip the frame to bare , and start over.
selling the wheels and all that will subsidize the change over, somewhat.
Campagnolo also sells cantilever brakes , for cyclocross racing .. they're nicely polished, too. (or Black)
