Bit of help with choosing 9 speed cassette.

Not sure so thought I would see if anyone has any advice.

Current cassette is an Shimano HG50- 9 30t.
Have been looking at Sram PG950 cassette.

Thing is does it matter if I get the 28, 32 or the 34?

This is for the 9 speed.
Thanks.

Regarding the rear mech, it will probably cope ok with the 34 but you might need to tweak the b screw. Regarding the chain, if you are keeping the existing chain I would think the 28 or 32 would be fine, the 34 might need a few links adding if you have any spares, or just buy a new sram chain to match the cassette

Just make sure that the chain is long enough to do the big-big combo. Otherwise the unobtainable gear can stuff the rear mech right through the back wheel. At best, that's expensive, at worst dangerous.

I have ordered a 32t cassette.
My chain isn't that old, there's no problem but my boys bike needs a cassette.
So I was getting the new cassette for mine and fitting the old one to his bike.
He might need a chain but LBS cheap one will be ok.
He only uses it to get to the train station and back now.
Unfortunately he is no longer into bikes.

Just fitted the new cassette, strangely enough it is a tiny bit away from going onto the small cog, it's trying.
Thought it would have been the biggest 32t cog not the 11t cog.
Job for tomorrow at some point.
