SRAM BlackBox GXP Ceramic Bottom Bracket

The SRAM BlackBox GXP ceramic bottom bracket exceeds the standards of even the most demanding rider. The SRAM Blackbox GXP bottom bracket's ceramic bearings are 10% lighter than standard steel bearings and require an astonishing 78% less energy to turn the bottom bracket than its closest competitors.

Ceramic bearings are more resistant to dirt, moisture, and are more resilient against wear and tear. Ceramic bearings are cut much more round than their steel contour parts which aids in reducing mechanical drag, which is the primary loss of power next to aerodynamic drag.
