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 bottom 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.
- Take the guessing game out of compatibility with this BB
- Wide 28.99mm bearing diameter increases stiffness
- Steel bearings are smooth rolling and durable
