This is the 1st commuter/ hybrid/MB bike i have so im not sure about many things. For example, the flat bar campy brifters so far i saw are 10 sp, now, the rear hub in this kind of bikes is 135 mms so no way to put a campy wheel in there that i know of. What I tought is to put shimano - campagnolo conversion cassette in there. Since the bike is 8 sp probably I wont be able to do it but change the hub is an easy step anyways, 2 hours tops! Probably that conversion casste can help you also, I have one in my road bike and works awesome.
The shimano drive train works fine? I mean... I can understand that the crank set works fine but the RD does work fine also? The other thing I read is that the Campy FB brifters are in two models, one for cantilever and one for regular brakes, wonder whats the difference because besides pulling a freaking cable i dont know what else it could be happening when pressing the levers.
Thans again for your response...
