Thm - BBright PressFit Bottom Bracket PF46-79-30
BBright is an asymmetrical Press Fit bottom bracket standard (e.g. CERÉVLO frames) which provides a great combination of performance and reliability. On the non-driveside the bracket outwardly shifts 11mm, the position of the crank arm or the height of the camp remains unchanged. Thus filling in the dead space and providing better axle support but without affecting pedal stance width.
The BBright PressFit bottom bracket cups need a case diameter of 46mm and a width of 79mm.
