TRUVATIV PressFit 30 bottom bracket

At SRAM we saw an opportunity to develop a better PressFit system that would combine all the benefits of BB30 and PressFit bottom brackets in one fantastic package.

The PressFit 30 features a pre-installed seal in the cups to further extend bearing life.

With PressFit 30, the main difference is the way the bearings are fitted into the frame. These are located in nylon shells that are pressed into the bottom bracket shell of the frame. This bottom bracket was designed for 30mm bottom bracket shafts.

The frame bottom bracket must have an inner diameter of 46mm to use this system. PressFit 30 for racing bikes requires a 68 mm wide housing, while PressFit 30 for MTB requires a 73 mm wide housing.
