Truvativ GXP Blackbox Ceramic Bearing Bottom Bracket

SRAM’s new Ceramic BB Bearings surpasses the performance over steel bottom bracket bearings. Lighter in weight, ceramic bearings require over 70% less energy to spin than steel bb's making them extremely efficient and fast.

Ceramic bearings also hold up better to dirt, dust, and water thus have a longer life than traditional BB's.

Truvativ's BlackBox products are the highest performing in the industry developed with guidance from the worlds fastes riders.
