A GXP bottom bracket will not work on a BB30 frame or any incompatible parts. “GXP” stands for “Giga X Pipe,” while “BB30” is short for “Bottom Bracket.” The “30” indicates the 30-millimeter diameter of the bottom bracket and spindle. SRAM Apex and Red BB are also compatible with this system.

How long should a GXP bottom bracket last?
It probably won’t make much difference though, as I’ve dismantled a couple of ronnied Truvativ BBs and have found that the bearings cosmetcially look fine, so it’s not rust that’s causing the problems in my particular case. Oh and nine months for a GXP BB used only in dry weather is about the best you can expect.

The wavy washer sets the bearing preload for cranks that don’t have a preload adjuster. Since this is an adapter, there is no adjuster, so you should use a wavy washer. as I said, normal gxp threaded BB’s and their associated cranks have no pre-load adjustment either, and no wave washer.
