I have a couple bikes running 10 speed campagnolo and am considering going 11 speed to take advantage of wider gearing. So, sticking with mechanical shifting I can go 105 (getting worried Campag won't be about in a while) and would need the chain, shifters and front/rear derailleurs. Will a Campag cassette run with the 11 speed set? I can get a 12-32 11 speed Campagnolo cassette but am I just better changing everything? Was trying to see what was the least I could get away with
