Worn cassette?

Hi All,

Just noticed a few of the teeth on my 12 cog look really worn - or are they designed like that?

One looks like a sharks fin and a few look "bent / leaning over".

All are dead straight when viewed from above.

Thanks,

Pat...

    I *think* they are designed like that, and those teeth are used as the shift points.

    Quite normal. They are made that way as aoeu says.

    On each sprocket you should find a number of differently profiled teeth to aid shifting - they are generally all aligned on the cassette too. If one sprocket doesn't match all the others, then you may have some damaged teeth - but it is unlikely in normal use
    Make mine an Italian, with Campagnolo on the side..
