EDCO Racer Hubs

I have had a set of wheels built using these NOS EDCO Racer Hubs:

I want to fit a Campagnolo Veloce 10 speed cassette.

The cassette fits fine on the freehub splines, but the lockring supplied with the cassette does not fit on the freehub. If anything, I would say the diameter of the lockring is too large.

Please advise.

11 and 12-up Campag Cassettes have different lockrings, could be that?

Have you already checked that edco didn't supply their own lockring with the hubs?

What diameter is your current lockring?

I bought the hubs as NOS (from Mercian), and they didn't come with a lock ring.

I have e-mailed EDCO but as yet have not had a response.

Couldn't find my vernier calipers yesterday, but I have the morning off tomorrow, so will have a good look and get measuring.

Just had a quick measure.

I reckon the internal diameter of these hubs, where the lockring will screw into is 25.55mm.

By comparison, I took the same measurement from a 10 speed Campagnolo Hub, it is 26.7mm.

That's why the Campagnolo lockring won't fit.

Any ideas?

Campagnolo have changed their lock ring thread sizes repeatedly. I know @jambon had trouble with this.

Basically you need to find the right size, so probably worth a visit to Condor, maybe asking a true Campag expert like Rohan Dubash (http://doctord.co.uk/) if he knows where to get stock, etc.

Cheers.

I am on hold to an EDCO distributor, might pop over to Edwardes before lunch.

He's very active on facebook too

EDCO distributor is being thick.

I think your best chance is to find a bike shop that has a spare. Time consuming though.

Condor might be worth a shout?

I will go to Condor one day next week.

Thank you all, for your help.

After much fucking about, and many visits to inferior bike shops, I've just been to Condor.

Sorted within moments.
