Description
Performance & Use Case
The Rotor PressFit 46mm Bottom Bracket is the platform for any frameset using a 46mm internal PressFit shell - BB386EVO, BBright, OSBB and PF30 framesets. Rotor's bombproof reputation is built on durability under load, and this bottom bracket family delivers reliable drivetrain performance for road and gravel bikes.
Construction & Materials
The cups are 100% CNC machined from 7075 aluminium alloy - light, strong and dimensionally accurate. Steel cartridge bearings are standard across the range; a ceramic-bearing variant is offered for Shimano 24mm cranks. Each variant includes the spacer kit needed to fine-tune the fit across the supported shell width range.
Compatibility
Fits any frameset with a PressFit 46mm shell. Variant options cover the major crankset standards: SRAM DUB (28.99mm, steel bearings), Shimano Hollowtech II (24mm, steel or ceramic), and Rotor/FSA (30mm, steel). The Shimano and Rotor 30mm variants are converters - they step the 46mm bore down to a smaller spindle - while the SRAM DUB and Rotor 30mm variants are native fits. Select the variant that matches your crankset and bearing preference.
