New Chain jumping.
-
I’ve put a new SRAM 9Spd chain on my 2008 Specialized Rock Hopper bike. It now jumps on the rear cassette. I’ve tried adjusting the chain but no good. Any suggestions?
-
It could be that the cassette is worn. Have a close look to see if any of the teeth are “hooked”. If you have had the chain on for a long time and it has stretched, it will accelerate the wear of the chain rings.

Hi,
As above, if the rear cassette teeth are worn dont ride it or it will soon bugger up your new chain in a very short space of time.

The normal thing when buying a new chain is purchase a new cassette???…
-
unless you leave it for a seriously long tome, generally every 2 chains I would buy a cassette
-
yeah i agree with changing the cassette…
just wondering, you got the old chain?
why not chuck it back on and see if it still jumps, then you’ll atleast no if it doesnt your in need of a new cassette

You are all right I put a new cassette on. Back on the road again. Many thanks to all of you. Keep on riding.
