Note, There are 2 types of SRAM/GXP BB Bearings - this is one, and the part ref MR22237-2RSV-B is the other.  It's difficult to determine which Bearings will be required without having removed the old one (note, this bearing on the non-drive side only, the other bearing is usually MR2437 or MR2437H8).  Check description of the other part ref as it is a slightly different configuration and generally used on the latest SRAM/GXP Bottom Brackets.
