I'm looking at rebuilding an older Cervelo R3 which had a Campy Record setup. Most of the gear is pretty old now and probably needs replacing, and I have a set of race wheels which are set up for Shimano 10 speed (these are also interchangeable with my Merida that I use for commuting hence why I have them)... I was planning on fitting out the Cervelo with new (ish) full shimano components, then read somewhere that cranksets are pretty much interchangeable...
SO, to save money - Even though I'd be committing a cardinal sin - can I use my old Campy Crankset + BB (which I know fits the bike), to work with a shimano Front Derallieur, Shimano Chain and Shimano RD + Shifters?
Any help appreciated thank you!
