Apex and Force compatability
I asked this in the bike mechanics section and got no response, so I'll try here too.
I have a Nashbar bike with Force components and I bought a 2011 Specialized Roubaix Elite with Apex today. I know the compact chain rings are interchangable so I plan on swapping the BB and crankset. The shifters are interchangable so I will do that too.
My question has to do with the RD. For the RD I know I need the longer cage for the 11/32 cassette, but can I just use the medium cage from the Apex RD and put it on the Force RD?
