SRAM DUB BB30 (Road or MTB) 68/73mm Bottom Bracket
The SRAM DUB BB30 (Road or MTB) 68/73mm Bottom Bracket mixes the durability benefits of 24mm systems with the lighter weight offered by 30mm spindles when using SRAM DUB compatible cranksets, whilst also allowing space for the bearings to be properly sealed against the elements. The aluminium cups are precision machined for a creak-free fit, and the bottom bracket still manages to achieve an impressively low claimed weight of just 82 grams.
