Bottom bracket standards might as well be a four-letter-word in the bike industry. Always changing, never cross compatible, and constantly causing headaches as we fumble through adapter cups and aftermarket pieces to try to carry your crankset from bike to bike. Designers at SRAM must have been fed up with the confusion, too, which we suspect has something to do with their design of the DUB PF30 Bottom Bracket. This bottom bracket doesn't introduce new standards when it comes to your bike's bottom bracket shell, fitting snugly into your PF30 frame just like any other PF30 bottom bracket, but where it differs is in the spindle. This new bottom bracket is designed to flawlessly fit SRAM's new DUB cranksets, with a 28. 99mm spindle across the board, allowing you to upgrade your crank, while future-proofing it. We're fans of SRAM's new take on bottom brackets, straying away from the never ending dilemma of shell standard compatibility, and instead looking to the crank itself to transcend one bottom bracket to another. This is achieved by using a standard inner bottom bracket bearing diameter of 28. 99-millimeters for stiff power when paired with a SRAM DUB Crank, but placing the bearings in a variety of bottom bracket sleeves to pair with any current bottom bracket standard on the market. This means there's no more stressing between whether a PF30 and GXP crank will work for you -- instead, you can rest assured that there's a DUB bottom bracket out there for your current bike, and your future bikes, so you can keep your dream crankset running with you for years to come.
