Since bottom bracket "standards" seem to change from day to day, SRAM offers just about every option on the planet. This is their GXP Pressfit MTB Bottom Bracket system. It is comprised of two sets of steel bearings, each in a nylon cup with a lip that sits against the edge of the bottom bracket shell. You press each portion into the respective side of a BB92 (mountain) bottom bracket shell. Then, you take any SRAM 24mm through-axle crankset and boom(!) you just made your non-standard bottom bracket shell compatible with SRAM's whole range of great Truvativ cranksets. The SRAM GXP PressFit MTB Bottom Bracket works with pressfit specific bikes only, like the Yeti AS-R Carbon.
