Rear sprocket movement.

[JonGeorge]

Hi,

I have a bit of movement in my rear sprocket, am I right in thing its the cushdrive rubber? It also coincides with poor gear changes.

[muzikill]

Movement as in loose which direction?

[JonGeorge]

I can move it slighty towards me and back towards the hub again.

You mean in-out? Check to make sure your spacers are in properly (or missing).

Should check axle and sprocket bolts are tight. Rubbers do not do anything in this axis.

Has back end been disassembled recently?

[JonGeorge]

Ok will do, and no, the rear hasn't been touched at all?

Is this a pointy or a curvy?

Check everything is there that should be there per these diagrams

And check your rear axle nut and rear sprocket nuts are torqued correctly (60nm and 100nm).

And it should go without saying but don't ride it until you've sussed this as some of these possibilities have significant chance of causing damage to bike and/or falling off.

That means you falling off, not just bits from the bike.

Id say if the there was a spacer worn or missing and the sprocket hub/carrier was loose then the wheel would have play in it. If not then the sprocket mounting nuts must be loose?

Absolutely, the OP might not notice that with the bike on the ground though.

[Bigmitch]

Poss the wheel bearings gone? Have you recently had the rear wheel in or out?

[Bibio]

if the whole wheel moves then i would suspect that the inner spacer is missing and if so then its knackered the carrier bearing.

axle nut loose.

if just the sprocket carrier is moving then i would suspect the carrier bearing is shot.

very unlikely that 5 nuts have come loose unless some numpty has fitted a chain and sprocket kit then forgot to tighten the nuts.

[Sid Squid]

As Bibio says; most likely carrier bearing.
