PF4624 (Pressfit 30) to 24mm Ceramic Bottom Bracket

Part$120

Rotor's PF4624 adapts 24mm spindle cranks to PF30 frames without compromise. CNC-machined 7075-T6 aluminum cups pair with hybrid ceramic bearings—steel races, ceramic balls—that roll rounder and harder than steel for lower drag and extended service intervals.
