Outer Chainring choices?
I'm looking for a replacement chainring after crashing and bending the current outer ring. I have Rotor 3DF cranks, with the inner ring a NoQ 39t of a 53/39 setup.
Would any 53t chainring work? Assuming I go with same specs (130mm BCD, N10, 5 Bolt, B-Type)?
Also, I see that the Ultegra chainrings don't look like they have the visible bolt holes that other rings have... are Shimano rings off the table?
