Hi All,
I have a SRAM XO chainset with a X2 spider. It has 38 and 24t rings on but I want to reduce the diameter a little to a 22t inner and probably a 36t outer. They are 104 bcd.
What are my options? Can i just fit any manufacturers rings as long as they are 104bcd or do they need to be specific to SRAM.
I have never bought outside the SRAM or Shimano options when I have bought new rings before so would appreciate some advice.
Cheers

Has no one changed a chain ring?
I doubt if the inner is 104.Probably 64.
jfb,
Yep, the outer is 104, not sure what the inner is.
99% of rings with the right BCD will fit, some have little tabs that catch but any good aftermarket ones should be fine.
Are your bolt holes regularly spaced ?
Some newer cransets seem to have weird distribution around the circle
