WTB: Shimano 105/Ultegra 11sp Cassette Lockring

Recently bought a second hand bike that came with a free 205 11sp cassette (bonus), but that cassette has no lockring.

If you have either of the above, either spare or from an old worn cassette, I'm happy to pay for it. SJS are asking for £12+PP which seems extortionate to me.

Thanks!

I think I've got one at home. I'll check but won't be there until 6. I'll have to post it though.

That's cool, would really appreciate it.

I'm sorry but it's an 11t HG lockring not 11s. You can try it if you like. Google is inconclusive on the difference. Seems to imply that is more to do with the tooth size than the amount of gears...
I'll post it to you if you want to give it a go.

any 11T shimano threaded lockring will work, I've just tried an old 8 speed job and it fits the freehub on my Shimano variant Campag Bora's.
if you want something flashy, sigma Sport sell a nice Token one for £4 plus postage.

@Heitzman I'd love to. Pm me your PayPal address and I'll cover postage.
@Mr_Bump Brilliant, good to know! Will stop off at a couple of bike shops on the way home to ask around.
