The DUB BB30 73 mm Road Wide bottom bracket by SRAM combines your Cannondale with gravel-friendly components

This SRAM DUB Road bottom bracket for 73 mm case width is your choice if you want to combine your BB30 Cannondale frame with wider cranks. It is asymmetrical and specially developed for Cannondale bikes. The spacers create space for the crank axle and thus enlarge the chain line. This places electronically controlled AXS front derailleurs in 2x12-speed drives further outwards, which in turn allows the use of wider tyres, e.g. in gravel applications. The DUB technology offers you the perfect compromise between large bearings and axle stiffness.
