Product Details

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.

I bought this to run Shimano cranks on my boardman frame. Great fit and runs smooth, highly recommended

Ric,

Was a good solution for fitting Shimao groupset to a Connondale Super Six Evo. There are many adapter to use 24mm cranks with a PF30 BB. Or to fit a 24mm BB into a PF30 frame. But this is a proper 24mm BB whcih fits directly into the frame. Had it fitted by my LBS and have had absolutely no problems. Works perfectly. Seemed nice and light to me.

  1. Boardman Elite Aero 9.2 has an 86mm BB, 46mm shell opening and 30mm FSA crank axle. Currently the bike has FSA PF30 BB which has been changed a couple of times, so I want to replace it with something decent. Will this fit please?

    Asked by Formerly BB30 (Sandhurst) —

    1. Sorry... 68mm shell width not 86 which is the same as a Tarmac SL4 to which I fitted one of these recently

  2. Hi although this is advertised as MTD no issues with road - what's the difference? For use with a Hollowtech II R8000 crankset in press fit 30 cups with a shell diameter of 46 mm and width of 68 mm
