American Classic Campy hub - Chain rub on dropout

[[email protected]]

So I built a new set of training wheels tonight with 2005 American
Classic Road Hubs, Open Pro rims, and Sapin CX Ray spokes. This is a
nice strong and light set of hoops. However, I mounted my Record 12-25
cassette on it and put it in my Trek 5200 and the damn chain rubs
against the dropout in the 12 cog. I don't have this problem with and
of the other 5 wheelset that I own. The chain has zero clearance with
this hub and all the other hubs give the chain about 1.5mm of
clearance. Has anyone had this issue before?

Thanks,

Ron

I have the same problem on my American Classic 420s running an American
Classic shimano to campy 10s conversion cassette. As a quick fix, I just
stuck a washer on the outside of the axle against the dropout and it
works just fine.

How much are these hubs? Shouldn't happen, poor design. Adding washers
to make this work is unacceptable, IMO.
