Bottom Bracket Dub BB30 68/73mm Sram

Product details

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 for the use of wider tyres, e.g. in gravel applications. The DUB technology offers you the perfect compromise between large bearings and axle stiffness.
