CENTRAL MOVEMENT CERAMICSPEED ALPHA BSA SRAM DUB ROAD

The CeramicSpeed ALPHA SRAM DUB BSA is a threaded bottom bracket designed for bicycles with a 68 mm BSA shell and compatible SRAM DUB cranksets. It combines ceramic bearings, hardened stainless steel races, and 7075 aluminum cups to deliver smoothness, protection, and durability.

Hand-assembled in Denmark, the ALPHA bottom bracket uses grade 3 silicon nitride balls and a dedicated sealing system to limit the ingress of moisture and debris. A solution for those who wish to optimize the drivetrain efficiency of their road bike.

Ceramic bearings to reduce friction

CeramicSpeed Standard bearings combine silicon nitride ceramic balls with hardened stainless steel races. The precision of the components is engineered to reduce friction and promote smooth rotation of the crankset.

Dedicated seals and precision dust covers

The custom seals work together with the high-precision dust covers to protect the bearings from moisture and debris. The sealing system helps preserve the operation of the bottom bracket during use on the road and in the most demanding conditions.

7075 aluminum cups

The 7075 aluminum alloy body combines strength and low weight. With a stated weight of 87 g, the CeramicSpeed ALPHA BSA DUB integrates into performance-oriented setups.
