This suits all GXP format SRAM & Truvativ Cranksets, including the SRAM Omnium.
The Blackbox Ceramic Bearing GXP bottom bracket is a high performance, external bearing bottom bracket. The GXP system captures the left side bearing between the spindle and the left crankarm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment.
The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry-free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long-lasting ride and SRAM’s gutter seal technology drastically improves sealing against the elements while reducing seal drag.
