    Surly Chainring Not Wearing

    I've got a Surly stainless chainring. I've had it about a year now, and while it does a good job of keeping the chain, it has never lost the chain suck.

    Even with a severely worn chain, I'm still experience chain suck.

    Any advice?

    replace your chain (and cassette) and try a thinner chainring.

    All the 4 bolt designs are designed to work with 3/32 chain (ie: 5-8 speed chain). If, by chance, you are using otherwise, it will bind/suck, as you described.

    More information on your drivetrain would definitely go a long way towards trouble shooting your issue.

    I'm using a 9 speed cassette and chain.

    Surly says that it will wear over time and chain suck will decrease. I had a few months where it seemed to be "loosening up", but lately it seems to be getting worse.

    It should eventually wear. The problem you are having is that the chainring is durable (theoretically, something that would make it worth having!).

    Wear on chainrings happens significantly slower, being that much more of the chain's load is spread out over the face of the ring.

    I had a 8spd cassette and chain laying around, put them on, and it works pretty well.

    8spd cassettes sure are heavy though!

    Had a similarly weird situation with an all new drive-line using an 8-spd KMC chain, Surly cog & SS ring.
    After switching things around, it turned out to be a small burr on the new cog.
    So, if the problem continues you may wish to try de-burring the ring with a fine-toothed file.
    The best is the one you want to ride most often..
