    Used Chainrings?

    Buying used chain rings a good or bad idea? How do you tell with the amount of life left in a chainring?

    For single speed rings, if the teeth look shark-finned, then the teeth are worn. A fresh chainring will have symmetrical teeth. Chain rings meant for multi-geared bikes have weirdly shaped teeth to assist in changing gears, making it much harder to judge wear.

    There are lots of good used chain rings for sale....a lot of people change their gear ratios before wearing out the chainring. It's very hard to wear out a quality track chainring. I have 20000 miles on my sugino zen and it's still in good shape.

    Because new chainrings just turn into used chainrings, so you're saving time when you buy used.

    OP, as long as it's not bent, there's no damage to the teeth, and there's no visible wear on the teeth, you should be fine.

    Well I'll be fooked. I thought it was a rather silly question. It appears I'm wrong (happens too darned often dammit)

    As for mihlbach's comment about geared chain rings. Even brand new ones look utterly knackered.
    I had a good bike ... so I FIXED it

    Yup, and if you ever see any for sale from be, definitely buy them, they'll be barely used. I'm constantly tweaking my fixed and SS bikes' ratios, and as a result it seems I now 'collect' chainrings.

    Actually, I'll never sell for fear of more future tweaking, but plenty flip them often. A great source is a swap meet at the local velodrome.

    How do you tell what a worn chainring looks like? I'd tell you to ask your mom, but she doesn't know either.
    HEYOOOO.

    That's a throwback.
    Phil Schwartz an ha?


    OP. check for bent/chipped teeth, and shark finning. Looks exactly what it sounds like.

    Don't worry about it.

    The process of shark finning takes a very very very very very long time assuming you change your chain when its worn out and said chain is of the correct pitch.
