lock ring

[patn]

I need to buy another lock ring, but I have no idea what to ask for in the shop and I don't have one on me to show them... Are there different sizes/types? Its for my track bike...thanks!!

Unless you have some obsecure type of hubs (French, certain Campag, etc) then you will just require a standard track lockring. If you just ask for a track locking you will be fine.

You'll probably need an ISO/English threaded lockring. This is what every bike shop gives you by default if you do not specify the threading. It's 1.29" x 24 TPI.

If you have high quality hubs like Campagnolo, Phil Wood or Miche, they use Italian thread. 1.32" x 24 TPI. I have a sneking suspicion that my Suntour Superbe Pro hubs also have an Italian threaded lockring. After all, they do use Italian threaded sprockets... I would not call any of these brands obscure though. French track hubs are closer to being classified as obscure, but I have to say that every French track hub I have seen (Normandy, Maillard) actually used ISO threaded lockrings, not French ones. Maybe I'm not quite old enough.

My Lollipops disk wheel uses ISO sprockets, but the lockring is a mystery. No-one has yet been able to identify the thread size. It's a good half a cm smaller in diameter than any other lcokring known, so it remains lockring-less. I will allow that one to be classified in the obscure category.

Al might have one in his shop at Hurlestone Park, the only issue is he will have to find it amongst all the other stuff.
