Hi, I am building a new old stock Cannondale R800 CAAD5 frame with Campy record 10spd. It seems like there is no room for the chain between the rear dropout/chainstay and the cassette.

When I first installed the rear wheel (campy record hub) the cassette would not freewheel properly. I found this was due to the screws that hold the replaceable derailleur hanger in place. After a minute or so with a file the wheel fit and the cassette spun properly.

I went to intall the chain I bought (10spd wipperman) and just draping over the cassette and chain rings, it seems as if there is not enough clearance for the chain to run without touching the frame.

Can a 10spd system be run on this frame? Anyone have any thoughts on this?
