    FSA afterburner 386 front chainring

    I have a cannondale 29er that comes with this crankset. I am using a single front chainring and the 39 tooth is a little large and would like to use a 36, 37, or a 38. Does anyone have any idea where to get these, if at all? thank you for any help you can give.

    You're probably gonna have to go to your LBS and have them order you one direct from FSA.

    FSA doesn't show anything lower than 39 on their site.


    In fact they show a 40 as one of 3 options on the cranks but don't show it available as a replacement?

    I didn't see anything listed by Blackspire either.

    This Shimano LX FC-M582 Crankset at

    plus this Salsa 4 Bolt Middle Chainring at

    Gives you a 36t and a whole new crank, bb etc for $125

    Sell the FSA and ring set from the shimano and you may break even. You also then have a crank that you can get just about any ring for. Good luck.

    These rings are a real PITA to find. For instance, some mailorder companies sell the cranks but will not sell the rings, even special order. I had Price Point tell me to try Universal Cycles!

    Anyway, FSA says they have tons of the 27 & 42 tooth, and they go for $50 each direct or have your LBS call Kyle (FSA) 425-320-3079

    Specify 9 or 10 speed...And, I learned that they make different rings for SRAM or Shimano shifting too. Is this really a succesful design plan?? At least mine shifts nicely with gripshift X/O.
