    24T Chainring for XX Crank

    I've been looking for a 24T chainring as an option for my XX 2x10 set up. Currently running a 39/26T front chainrings. Anyone know of aftermarket suppliers that fit the XX BCD pattern? Thanks!

    PS For that matter, I can't seem to find exactly what the BCD is for the XX small ring. NOT LISTED anywhere on SRAM/TruVativ website...

    The BCD is 120/80.

    I believe 26T is as small as will fit.

    The trouble with common sense is it is no longer common

    Same issue. Can I change the spider from 120/80 to 104/64 and keep the azle and crankarms or do I need a new crank to get to 38/24?

    Try posting in the drivetrain forum too. You might get more responses there.

    Unfortunately, you can not change the spider on XX cranks.

    I think you have to go to XO to get the smaller chainring options.
