Im not a big fan of some of the cannodale propriety stuff. I like the fact That I bought a bike that was equiped with off the shelf SRAM, Avid, and Rock Shox gear, stuff which came with its own manual and would be easy to replace if i needed to. When Buying a frame I look for something that is of a quality Where i wouldn't mind upgrade components on. I have used shimano and sram stuff and Have ever had a major problem with either that wasn't my own fault
