DUBble up for your fat bike.

Breaking through standards, SRAM is ready to take the bottom bracket industry by storm with the DUB BB121 Pressfit Bottom Bracket for Fat Bikes. This bottom bracket revolutionizes the way cranks and bottom brackets pair up by offering a standard spindle diameter that pairs up with their DUB bottom brackets, which come in an array of sizes to fit virtually every bottom bracket standard currently on the market. This means that regardless of what your current or future bike may be, there's a SRAM DUB bottom bracket that will play nicely, allowing you keep your upgrade moving, and preventing parts from becoming obsolete with changing standards.

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.
