backstory: I'm building up a late '90s Bianchi Trofeo (I think) frameset for a co-worker to use on the Aids Ride.
I told her I had a nice pair of wheels with Campy hubs and the 8-S cassette to go on the rear (this would come off a rear with a tubular rim that has no tire and so is a spare).
So...I find the wheels. Nice indeed with Mavic OpenPro rims and Chorus hubs...pull the cassette off the other Chorus hub and slide the cogs on the new hub. Now just screw that lockring on and...no...it will... not... fit...
The old Chorus body uses a lockring with a 29 MM threaded OD, the new one looks like it takes a 26mm OD.
What gives?
Didn't Campy standardize these things?!? (and I thought Shimano was bad!)
help me out, I can't find the info in the catalogs, don't even know the exact years of the hubs involved...what lockring do I need to make this work?
