GXP BB86 Bottom Bracket

Since the idea of a bottom bracket "standard" is in flux these days, SRAM offers just about every option on the planet. This is their GXP Road Pressfit bottom bracket system. This is comprised of two sets of steel bearings, each in a nylon cup with a lip. You press each set into a side of a BB86 (road) bottom bracket shell. Then, you take any SRAM 24mm through-axle crankset and boom(!) you just got your non-standard bottom bracket to work with a whole bunch of Truvativ cranksets.

The SRAM GXP Road PressFit bottom bracket works with pressfit specific bikes only, like the Scott Addict R1 and CR1 SL. The claimed weight of the SRAM GXP Road Pressfit bottom bracket is 91g.
