My chain snapped at the weekend. Yesterday the missus nipped into the LBS for me. She came back with a SRAM chain which I fitted last night (following the instructions and using the old chain to determine the chain length). Seemed to run lovely on the commute in to work, which is mainly flat / downhill. No problems shifting gears. But on the way back it was slipping a lot – mainly when I got out of the saddle for some hills. The rest of the drive chain is shimano – but surely a standard SRAM chain should be compatible? The cogs aren’t particularly worn. I’m at a loss to explain it or know what to do to remedy it. Any ideas, bike doctors?

Most likely that the cassette is worn

New cassette needed.

You should’ve gone to Cycle Surgery.

Yes… I had exactly the same….. New cassette time

new cassette or old chain and powerlink

How much wear had the old chain?

And if you don’t know…, you need to change the chain at a maximum of .75 and then you’ll get 3 chains to a cassette.

As above, or sticky link on new chain which I had once.

Thanks all. Looks like a new cassette is needed. But the old one doesn’t look that worn. Probably got 2000 miles in it.

Wrightyson. What did you do about the sticky link? How did you know which link it was?

It’s almost impossible to tell how worn a cassette is by looking at it.
Either put the old chain back on with a power link or get a new cassette.

Why couldn’t you have reused the old chain? Ok you’d probably have shorten it by a link or two, but unless you’re on a SS that should be ok.
