SRAM Dub BB30 MTB Bottom Bracket

Description

The Sram Dub BB30 MTB bottom bracket has been developed following the Sram Dub cranksets. The Sram Dub BB30 MTB bottom bracket bearings have an inside diameter of 29mm and have to build a bridge between 24mm and 30mm axles. Because Sram can now entirely focus on this new standard, rigidity and durability are significantly improved. In this way, an even better ratio between the front blades, cranksets, crankshafts and axles is achieved.
