Does it fit ok? I have a little problem:

When i completely tighten the crankarm on the axle with a plastic nut the sranks almost stop spinning (lots of sticktion - if i untighten cranks a little they spin fine) - do i tighten them too much or there should be some kind of spacers between crank arms and the BB bearings?

Didn`t experience this problem this XT BB...

Mega EXO is a double bearing design, it is wider then the XT it will not work together.

omg! thats a real pity

but the size of the cups is the same as XT was - i suppose the double bearings design has wide DH bottom bracket - not BB-9000 though
