    Brand new and busted

    Is this normal?

    I just bought this on ebay and that's probably my first mistake. X9 crankset. Is it normal for the teeth to be chipped and uneven fresh out the box?

    And I guess more importantly, will it affect the ride? I still have the option to return these but wanted to get some opinions first. This is my first crank purchase.

    Does anyone ride with worn teeth worse than this without problems or should I return these and buy from my LBS?

    I don't think it is busted at all. I believe the teeth are that way to aid in shifting performance.

    Not to worry. Those all support shifting.

    That said, rmember when you remove the rings that you orient them in the same way when you put them back.

    I wondered the same thing when I first inspected my chain rings.

    The cut and sculpted teeth make it easier for the chain to dis-engage and switch to the other chainring.

    The key to solving any problem is to understand and address the underlying cause.

    Yes - its normal for the teeth to be different lengths (as others have mentioned

    Yes - it will affect your ride. It should vastly improve it to have smoother shifting gears

    thanks for all the replies. I found a video and link to Sram's chainring design.
