SRAM Bottom Brackets | GXP Blackbox Cups w/ Ceramic English MTB Road 73/68

This is an SRAM BlackBox GXP Ceramic Road or Mountain Bottom Bracket. The Blackbox 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 bottom bracket. 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.
