The bottom bracket with DUB axle, the only unifying component between the cranks, protects the fluidity of the power to the transmission.
The central SRAM DUB has a simple task: connect the cranks and protect the fluid and lasting application of power to transmission.
To allow this unique objective, SRAM designed the DUB pin so that it is the only unifying component.
An oversized pin to work with all the specifications of the central movement.
For better compatibility with cranks. For better protection from atmospheric agents. For longer performance. To be stronger, smoother, easier.
A single oversized pin to work with all the specifications of the central movement
Gutter Seal Technology protects against weather
Notably lighter than the GXP system
Sealed cushions available in both stainless and ceramic versions
DUB
The relationship between the pivot of the central movement and the bearing is the heart of DUB technology. It is the point where rigidity meets durability, to better integrate the relationship between crown, pedivella, pivot and central movement. This comprehensive system development approach is a guarantee of better transmission performance.
