Truvativ GXP BB for Specialized OS 84.5

Specialized had stiffness in mind when they started designing bike frames with a proprietary, 84.5 mm shell size. And the Truvativ GXP BB for Specialized OS 84.5 complements that nicely. Sealed cartridge bearings spin smoothly and SRAM's Gutter Seal technology keeps water and debris out of the equation to make your bearings last longer. The Truvativ GXP BB for Specialized OS 84.5 is NOT compatible with traditional BB30, PF30, or GXP frames.

•  Only compatible with Specialized OS 84.5 mm BB shells
•  Smooth rolling cartridge bearings
•  Gutter Seal technology protects your bearings
