for the record, it’s SRAM xx1 crank
i tried fitting a Hope BB tonight with a GXP adapter fitted, and i have a bit of a problem… the bearing on the non drive side (the side with the adapter fitted) doesn’t spin…. so when i install the crank arms to correct torque setting the crank will barely move.
so i took the cup out and installed it on the crank out of the bike and sure enough, the cup is one solid mass along with the crank. this rules out any issue with the frame/spacers etc
i plan to give Hope a ring in the morning and failing that a trip to the LBS, just wondered if anyone could offer any advice?
