Rear cassette

[ScotiaLass]

Okay, I have replaced the chain on the MTB but now it's skipping all over the place!
I've been told I should have replaced the rear cassette as well. What should I replace it with?

The bike has a 'Sunrace 9 speed 11-34' on it.
I want something a bit better. Suggestions please?

You should be able to replace it with any Shimano compatible cassette. Shimano (obviously) or SRAM would be my choice and both companies do 11-34 9 speeds in various grades of quality depending on how much you want to spend.

Assuming you wish to keep the same range of gear ratios I would go for a SRAM PG-950 11-34T

Not cheap and I'm not sure whether the quality is any better than Sunrace or not? Maybe someone else can advise on that.

Take yer pick! My personal preference is SRAM or Shimano. You might want to match brand with your new chain, but it's not essential. Worn cassettes with new chains doesn't work, as you found out. Neither do new cassettes with worn chains. How are your chain-rings? (They last a lot longer than chains/cassettes).

Edit .... I would go with @sittingbull 's SRAM PG950 at that discounted price.

I have a Shimano SLX on one of my bikes - the £20 one in Brandane's link.

Hard to see how it's worth spending any more, but if you fancy something dearer either the £30 Shimano XT or the £30 SRAM will almost certainly be quality pieces of kit.

I was just looking at that one...seems a good price.
Of course to fit myself I'm going to need the tools...does it ever end

Chain whip & lockring tool

The lockring tool shown above with the central locating spindle is preferred by some, including myself.

It never ends, but the tools will pay for themselves

Might need to replace your front chainrings too...

Gawd.....

Are they sized like the rear (11-34) or a standard fit?

 

[ScotiaLass]

How do I know if either/both need replacing? Would a photo help?

 

[sittingbull]

I'd be surprised if your chainrings needed replacement yet (unless it's an old bike with previous wear).

I've got over 15000 miles on mine on a road bike. If you're constantly riding on gritty/gravelly trails then they may show signs of wear.

EDIT: cross-chaining (big/big or small/small wears them prematurely).

Yeah...gravel towpaths etc
