I picked up a really nice bianchi nuovo racing 12v. I say its from 1984 but I think it has a unique set of parts. Its a red frame with N.R campy derailleurs and a beautiful campy 175 strada crankset. Black Modolo "speedy" brakes are sorta cool but less functional..Overall its in good condition and o yea its got campy record hubs and mavic SUP reflex rims. Dura ace freewheel and a nice suede bianchi seat. Im stoked! But I was thinking that maybe the derailleurs and crankset are just too nice to ride. I have cheaper suntour superbe cranks and a replacement shimano derailleur I count use.. Would riding these Campy parts be as rewarding as they are worth? How much does their value diminish after use? and how long do they even last?
