Hopefully a quick Q.. but is there any difference for the cranks between a BB30 press fit BB and a regular one. I have an X1 chainset that came with a BB30 bottom bracket that I want to fit to a bike with a regular threaded 73mm bb shell – can I just buy a threaded GXP BB or will it require different cranks? I suspect it’ll be OK.
Difference between cranks is BB30 is a 30mm axle and std shimano is 24mm (GXP crankset are 24mm tapering to 22mm?). Off-hand I’m unaware of any BB that will fit a BB30 crankset to std threaded BB shell, it’s normally the other way round that ppl want to do it.
