Hey all,
Anyone know if the 1980 6 speed campy alloy freewheels had interchangeable cogs for the 5th and 6th position.
I know campy made A cogs for 6th position and B cogs for 5th, but they also made AB cogs to fit both.
I guess my question is , are the A &B cogs interchangeable from 5th to 6th, the A cogs have a groove and the B's don't.
Who's the campy freewheel expert here?
Thanks
