Rotor PF4630 (BBright) to BB30 Steel Bottom Bracket Info
Rotor has had a long partnership with Cervélo. They were the first company to provide a crank that worked with the Cervélo-designed BBright standard. It only makes sense that you can find the necessary bottom bracket from Rotor. This is the PF4630 Steel Bottom Bracket.
This is for the BBright Press Fit Standard. BBright refers to a bottom bracket shell 79mm in width, with an inner diameter of 46mm. The inner diameter of the bearings is 30mm, which matches up with the exterior diameter of 30mm thru-axle cranks.
In terms of cranks that fit in the bottom bracket, it is Rotor’s 3D30 and 3D30+. It also fits BB386 EVO cranks.
The kit consists of two cups with bearings pressed in and a sleeve. Press in one side, then the other. The bearings are steel balls rolling in steel races. Weight is 102g
The Rotor PF4630 Bottom Bracket with Steel Bearings allows you to mount Rotor 30mm and BB386 EVO cranks to Cervélos and other bikes with the BBright standard.
