I got it all off and cleaned it up. What I found is that the bike has everything Campagnolo except the cassette which is brandless and the chain which is shimano. I played around with the rear derailleur but could not get it to shift perfectly (makes alot of noise on certain levels). I'm guessing there is something to do with that the chain is shimano and the cassette which is not campagnolo. am I right or am I missing something?
