Does anyone know if these are available, and if so who supplies them? I am currently running SRAM Force with 53/39 and the BCD is 130mm. However, I want to fit compact rings but all the adverts suggest they are 110 mm.

Any advice welcome. Thanks

    I think the diameter of a 34 tooth chainring is too small to fit on a 130mm PCD.

    38T is the smallest you'll get on a 130 BCD crank unfortunately so its either a new crank or a wider range cassette at the back if you want lower gears.
    Compact chainsets use 110 BCD and got to 34T

    Someone will also be along in a minute to say you just need to MTFU and ride up hills in gears that may make your knees explode.

    Thanks for the replies. You've confirmed what I thought. Looks like I'll be spending some money.....and saving my knees!
    Cheers

    yep, you need a 110mm BCD crank. This goes down to 33t minumum.
