It's an invisible technology that adds minimal weight and helps you get to your destination faster. It means any eTap AXS bike can be retrofitted with power. DUB technologyThe crankshaft and bottom bracket assembly is at the heart of DUB technology. This is where stiffness meets durability. SRAM has gone a step further and made everything even simpler and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drivetrain performance.
