I need a washer or "spacer" about a 1mm or less thick that will fit around a Italian thread fixed cup. I'm trying to fine tune the chainline on my track bike where the old 151 Pista arm is tightening up a hair too far inboard. I'd rather not respace the rear hub. I think bringing the cup out a little will cure things. As it is the inside chain side plates are just catching a bit on the chainring and it's very noisy. Thanks in advance if anybody has something that will work or can point me in the right direction.
Cheers, Jon Williams
