CeramicSpeed Ceramic Race Bottom Bracket - PF30 to GXP (SRAM) Info
The CeramicSpeed Ceramic Race Bottom Bracket PF30 to GXP exists for one reason: to put the least possible friction between your legs and your drivetrain. Designed to mate a PF30 shell with a GXP crankset — the SRAM-specific spindle standard with a 24mm drive-side and 22.5mm non-drive-side diameter — it uses Grade 3 Silicon Nitride ceramic ball bearings pressed into hardened steel races for a measurable reduction in rolling resistance over conventional steel bearings.
The aluminum cups and sleeves are machined by Rotor in Spain, then the bearings are pressed into place at CeramicSpeed's facility in Denmark. The PF30 format uses a 46mm shell diameter — wider than BB30 — which allows the cups to press directly into the frame without snap rings, keeping the assembly clean and serviceable. Lower friction and longer service intervals are the practical result of the ceramic bearing design, which is why this standard has found its way into professional racing at the highest levels.
