Jeff:

You may have a part incompatibility issue there.

Campagnolo's lockring threads are 1.32" x 24 tpi.

Most other (non-French) ones are 1.29" x 24 tpi.

A non-Campagnolo lockring may be too tight to fit properly on a Campagnolo hub.

I would suggest getting a proper Campagnolo lockring, just to be safe.

Fwiw, I've never seen a left-hand 1.32" x 24 die, and it would be tough to chase those threads even if you had one, as they are smaller than the cog threads, and the shoulder of those would stop the die at some point.

This is why it matters when the lockring is missing from a used Campagnolo rear track hub....

does anyone know a source for italian threaded lockrings? i have some low flange campy hubs that i just laced up, i tried to thread a phil wood lockring on them and it gets really tough to turn after about 1/2-3/4 of a revolution. there are a few spots where it looks like the threads were dinged. i cleaned them up a bit with a small file but still feels exactly the same.

right now i have what seems like two options. 1. get the file back out and very meticulously file the area of threads were i think the friction is coming from then grease the threads up and force the lockring on, lol. i'd rather not.

2. find the 1.32 x 24 left hand die so i can chase the threads. i'd rather do this. does anyone have this die? would you loan it out? i'll pay shipping both ways.

is this die more common than i'm thinking and could it maybe even be found in a shop? or better yet, in the nice campy tool kit at the local bike co-op????
