Chain Slipping.

Hi all,

Popped my bike in the LBS for a service, they also ended up replacing the chain - since then my chain seems to slip all over the place. I mentioned this to them today, they explained the cassette is still in good condition and the slipping issue will sort itself out after around 60/70 miles - basically when the chain stretches and fits better to my cassette. Is this correct?

    seems odd advice. Have you tried adjusting the barrel adjuster on the rear mech to see if that makes it any better?

    It's hard to tell if it's worn just by looking at the cassette. If it's actually jumping forwards on the sprocket teeth then that suggests the cassette is worn. I replace my chains frequently and take the view that the cassette will need changing when a new chain starts skipping. 4 chains so far and still no skipping.

    I have replaced chains on both of our kid's mountain bikes (read frequent drivetrain abuse / little maintenance) and in each case had then to replace the cassette too because the new chain was skipping. New Cassette sorted it out.

    If you run your new chain on a worn cassette you'll wear the chain a lot faster, and when you inevitably replace it the new one will skip again.

    Try a new cassette.

    The alternative is to run worn chain and cassette together until one of them breaks. However, by then you'll also have worn out one or more of your chainrings, so it might not be the cheapest strategy in the long run.

    Mine did the same after replacing a broken chain, needed a new cassette.

    LBS advice if rubbish. If you end up with a chain replacement, chances are your cassette has had it. I now cycle my chains round and as above, and the cassette has last 2 chains and on 3rd
