Bottom brackets DUB™

The new axles are a smidge under 29mm (28.99mm, to be precise) in diameter, increasing stiffness over previous 24mm spindles. In order to ensure compatibility there's also a range of bottom brackets that allow the cranks to fit in any current frame, whether that be BSA threaded, PF92, BB30 or whatever. The bottom brackets have a new sealing system that, SRAM says, is more durable than before.
