The BBs are different between XT and X1, but the spacing should be the same. Some SRAM crank sets use additional washers to space out the cranks which XT doesn't.

Daffy - just noticed your comment re BB. I have a GXP SRAM crankset, I thought that fitted a standard hollowtech BB?

No. GXP use different bb as the. Non drive side floats in the bearing alot easier to fit than shimano just need 1 8mm hex key. Also if bb 73mm wide no spacers required.

Am I right in thinking you will need an 11-speed freewheel to the replace the 9-speed?
