    Replace the chain.

    Possibly you are not maintaining the chain well (degreasing and re-lubing) but alternatively it is possible you are not replacing them often enough.

    How did it break? There was a bad batch of chains that had fractures in the side plates (affected Shimano, SRAM and KMC) but that was a long time ago.

    If the same chain has broken twice in 12 months, I would replace it. As blorg says, it may be faulty. If it breaks again when you are giving it some beans, the consequences could be nasty - not worth the risk.

    Are you shifting under load? If so, this places a lot of lateral stress on the chain, especially when shifting between front chainrings. By all means, keep the cranks turning at the same speed when you are shifting but momentarily back off on the torque you're applying. That way, you will "thread" the chain nicely from one ring to another, instead of ripping it off one ring and mashing it on to the other. If you have been shifting under load, it would also be a good idea to check the condition of the teeth on your chainrings and cassette, as they may have suffered too.

    Thanks lads
    seem to have lost the pin in the link where it snapped.I"d say a bit more cleaning and lubing would be no harm ;).
