Sram BB30 Pressfit Bottom Bracket 68/92

Sram BB30 Pressfit Bottom Bracket 68/73

To achieve a better bottom bracket pressure fit system, all the best of BB30 and Pressfit have been combined into a single bottom bracket.

The key difference with the Pressfit 30 is the way the bearings are housed within the bottom bracket shell. The bearings are located inside nylon cups that are pressed into the bottom bracket shell of the frame. This type of bottom bracket is only compatible with 30mm axle cranks.

Compatible frames must have a 46mm inner diameter in the case.

The Pressfit 30 for road requires 68mm and the same for mountain bike requires 73mm.
