Hi all,

I have just fitted a SRAM GXP bottom bracket with a Sram Omnium crankset. Installation of the bottom bracket goes fine until I try to tighten the cranks down.

Somewhere around 50 in. lbs of torque the cranks go stiff and won't spin. I have tried with and without the spacers and the problem persists.

Any ideas appreicated

Any ideas appreicated

1) Spacer(s) and seal(s) installed correctly? Possibly dragging on the crank?
2) New or repainted frame? BB shell faced?
3) Cups installed to proper torque? Shell threads good or need refacing?
4) DS crankset + axle inserted fully? How much axle is protruding out of the NDS?

I have tried with and without the spacers
The axle is fully inserted.
One issue is that the central dust cover is too wide for my frame, when both cups are inserted the threads hang out of the frame.
So using the original dust cover from old crankset which fits fine
