I've been lucky enough to get my hands on a NOS one of these but I need your help... It's missing the bottom bearing race, so it looks like I'm going to have to make one. I've found a good picture of what I'm looking for (below) but can you tell me;

a. what it's made from?
b. any chance you could take some measurements?

Greatly appreciated :D

a Chris King race should work proper. They can be had on line easily for under $20. What diameter? 1 1/4 or 1 1/8?

Excellent advice! I have a CK on my Surly, so I'll break that down this afternoon and check. I'll keep you posted.

I should have one and will send it pro bono if I do. Need to check diameter.

Thanks Jason. :D

I tried my CK headset and it runs okay but as you can see there's a huge gap at the bottom and you can still see the bearing. The CK website lists something called "1-1/8" +5mm Baseplate" but there's no picture or drawing so I've no idea it that would work.

I see. Def needs a flange to keep the bearings clean.

The +5mm baseplate is just 5mm taller than a regular one. Imagine the standard baseplate with a 5mm spacer underneath it if that makes sense.
