    Replacement crankset for Shimano-M570 (4bolt)

    I am working on a Diamondback X6 (circa 2000) with worn and bent middle and inner front chain rings.

    The current crankset is Deore LX M570 (22-32-44, 175mm) and I am having trouble finding replacement chainrings or a full crankset online stores or ebay. It must be ancient ?!

    Can anyone recommend an alternative crankset/chainrings I could buy & install?

    Thanks

    I am 99,9% certain that any 104/64 4 arm chainrings will fit.

    Shimano M442 Square Taper Chainset


    or

    Shimano Deore Chainset 9sp M590

    Often you can find entire cranksets for less than the price of all 3 chainrings.
    Duct tape iz like teh Force. It has a Lite side and a Dark side and it holdz the Universe together.

    If it's a 4 bolt chainring then it is likely 104/64 and just about any replacement ring will work.

    If there is a community bike building/repair centre like Bike Again (Bike Again | Ecology Action Centre) here in Halifax, I'd go there first to find some used parts.

    Otherwise a good LBS should be able to order rings of all different BCD and tooth counts.

    Lastly, Jenson Shimano Deore-Lx M570/M571 Chainring > Components | Jenson USA Online Bike Shop has a replacement for your middle ring so if you just want to replace that, that might be a good option.

    Odd, that Jenson page seems to indicate it's a 5 bolt ring, but your title says it's a 4 bolt.

    Thanks for the response folks! @Slash9 I have seen the M570 offered in both 4 and 5bolt patterns, my version is the 4 bolt.

    I will take apart my chainrings this weekend and see if I can get replacements from my LBS, if not Jenson is next.

    Cheers
