SRAM BB30 Pressfit 30 68/92mm Bottom Bracket

The SRAM BB30 Pressfit 30 68/92mm Bottom Bracket features an integrated seal, pre-assembled into the cups, to further prolong bearing life, but the key difference is how the bearings are fitted into the frame. The bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. This bottom bracket is designed for 30mm spindle cranksets.

Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell.

Advantages weight savings, a narrow Q-factor, increased ankle clearance, improved bearing durability, stiffer/stronger crank construction, and ease of installation are all advantages. Increases frame stiffness by allowing larger diameter frame tubes.
