Chain slipping?

Hi All,
I've had my bike ( a Tricross triple) since Christmas and I do about 100km a week.

This week I noticed that when on the smallest 3 cogs on the rear cassette and the middle chain ring the chain seems to 'slip', especially when I push harder on the pedals. Could this be due to the chain stretching? If so, what's the best remedy, please? Could it be something else? The chain is a Shimano HG73, and is generally kept quite clean!

Thanks in advance,

  • Slip or jump ? Measure chain should be exactly 12 inches centre pin to centre pin . Replace Chain and cassette .

    Definitely replace the chain, then give it a try and see if it solves your problem. If not, you'll need a new casette as well.

    It's best to change your chain quite regularly, before it gets a chance to mess your casette up with it when it has worn. It becomes a lot more expensive then.

    Before you spend any money make sure that your gears are indexed properly. What you describe is consistent with gears that are slightly misadjusted. Worth checking before you splash out £20 on a chain and £40 on a cassette. IMO if your cassette has only done around 4500km then it shouldn't need replacing.
    More problems but still living....

    Thanks, chaps.
    I will get the gears looked at (I'm technically inept but luckily I admit it) before I spend any money. The chain and cassette both look OK to me though.
