For road but should be not different?
So std road shell - 68mm
Have SRAM Apex cranks
Fitted Hope road BB with GXP conversion (admittedly in a rush) before work this morning.
All assembled with no spacers - tightened and bearings overloaded.
Stupidly removed and fitted 2 1mm spacers and the same - now at work.
My thoughts on what went wrong? - Took up the slack but didn't back off and then reload? Thinking about it and viewing the Hope video me thinks that the GXP spacers were not butting the axle and thus overloading the bearings (too tight to turn).
So - Go home later - remove cranks and cups - remove all spacers - reassemble - take up slack, loosen and then load to proper torque - Does that sound reasonable?
