Afternoon all,

I'm after a bit of advice... I bought a Kona Fire Mountain about 2 months ago, and while giving it a good degrease last night, I noticed that my chainset has lost a few teeth.

They haven't completely snapped, but some are significantly shorter than the others, and have lost their sharp point. Some are pretty much half the length of others.

Is it normal for them to wear down? Or should they be a bit more robust than this?

Cheers in advance for any help. :D [/list][/code]

    Assuming they're on the outer ring it's most likely intentional, to help the chain shift, don't worry about it.
  • Sorry, I should have mentioned....

    It's happend on a couple of teeth on both the outer and middle chainring.

    yes teeth are different shapes. does it repeat around the cog? have a look in the FAQs for an example.
