Cassette lock ring

MB Lacey

I bought a bike last night without wheels, so was given the cassette separately.
I've just noticed there's no lock ring plate in front of the 12t ring.
Do I need this before I fit wheels?
It's a 2007 bike with ultegra components.
I've googled images of 2007 cassettes and they all have a lock ring.

I've attached image
Thanks

Have you even got the full 10 speed Cassette there? I can't count 10 cogs but it could be the picture And yes the lockring comes with the cassette and you will need to get one to fit the Cassette to the Freehub.

Thanks, that's what I thought.
Yes deffo 10 cogs, I've just cleaned black grime off all of them.
Photo wasn't great sorry.


It's an unusual cassette with 3 black spacers, 18t is attached to 19t and 21t is attached to 25t, which is why I thought there might be a slim chance there was no lock ring and that was ok.

Ok, I will have to hope the guy has the lock ring and meet up with him again.
Thanks.

Actually I have an old lock ring in the shed from a shimano 8 speed.

Can I use that or do I have to have a 10 speed lockring for a 10 speed cassette?

Should there be more than three spacers? The last cassette I fitted (2013 105 10 speed) had one between each cog, apart from the first three or four which were rivetted together? I think seven spacers in all

You're right, there's 4 black spacers and a metal one between 18/19 and 21/23 (just counted the teeth on the last cog and there's only a 23, not 25).

Bollix.

It was sold as an 11/25, turns out it's a 12/23.

You should have one spacer between the large cog and the freewheel base at the hub. This cog should have two smaller cogs joined as a three piece unit. Then there are a series of back spacers between the next 4 cogs, descending in size - then the smallest three have a sort of lip/ spacer built in. Finally, there is a spacer and lock ring to fit with the cassette tool.

Only ordered the cassette / chain yesterday afternoon from Swim Cycle Run, 24 hours later, free postage, delivered to my workplace, with lockring:

They had sold out of 10 speed Tiagra / 105 chains, so I had to buy the Ultegra.

:rolleyes:
