About Sram Dub BB30 Road Wide 68mm Bottom Bracket
The DUB BB30 68 mm Road Wide bottom bracket by SRAM brings gravel-friendly cranks to your frame.
This SRAM DUB Road bottom bracket allows you to add a wider crank to your BB30 gravel frame with a 68 mm over locknut dimension. 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.
