The project bike is a 2010 Cannondale Quick CX Ultra, which has a 9 speed Shimano Deore rear derailleur. Is the cable pull compatible with a SRAM Rival shifter?
If not, I guess I'll put a new x7 or x9 on there. But I'm trying to build this as cheap as possible, and I already will need to convert to mechanical discs, I think. It has pretty basic Shimano hydraulics, probably replacing with Avid BB7.
