The SRAM DUB Road bottom bracket is designed to accommodate wider cranks on BB30 gravel frames with a 68mm over locknut dimension. With strategically placed spacers, it creates ample room for the crank axle, expanding the chain line and facilitating the installation of electronically controlled AXS front derailleurs in 2x12-speed drive trains. This adjustment enables the use of wider tyres, ideal for gravel applications. Leveraging DUB technology, this bottom bracket strikes the perfect balance between large bearings and axle stiffness, ensuring optimal performance and reliability.
