    bent teeth on cogs... help!

    I managed to bend the teeth on my third cog today.. If you look a it closely, you can see that the teeth on the third cog is closer to 4th cog than on the 2nd..

    It causes my chain jump everytime..

    What might have caused this? bad shifting? or just leg power ?

    is this repairable or is it time to buy new cogs??

    BTW the cogs are less than 2 months old..

    pic is below,

    thanks!

    Well you can try to remove the individual cog and hammer it back out. However yes bad shifting under load can certainly do that.

    I love that no UN avatar Hunter.

    Dex max, You musta really been crankin hard while shifting dude! You might want to try taking some cogs from a retired cassette but flatening them with a soft hammer might do it. Use a brass hammer with an oak board under the cog to try and gently tap it back straight.
    Basher of trees and going downhill in distress.

    Take a better photo and send it to the maker, explain what happened and how dissapointed you are, not to mention the inconvenience it has caused.
