Chainring bolt diameter what is 104pcd?

konaben82 · Sep 7, 2013

I should know this bit I don't... Can anyone tell me if 104pcd will fit a standard modern shimano/raceface 4 bolt crankset? Or is it bigger? :facepalm:

This is the chainring I have in mind

Yep 104 is the standard for 4 bolt mtb middle and outer chainrings so will fit Shimano and Raceface. Some older XTR chainsets use a different bcd but that's the only one I know of.

Really modern at the moment is 120pcd I think. Probably wont be that though.
