SRAM Dub BSA Bottom Bracket

Model: SRAM   |   Asin: B07BRVHM6Z

SRAM's new DUB BSA Bottom Bracket takes away the guessing, the stress, and the downright frustration of bottom bracket standards. The DUB BSA loads you up with a bottom bracket that threads into a standard English Threaded shell and pairs with any SRAM DUB crankset, so you won't need to mess with finicky adapters, or resort to the crank you weren't craving just to run a clean setup. 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 bracket itself to transcend one shell to another. This is achieved by using a standard inner 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. This particular model threads into your English style bottom bracket shell just like any other standard English bottom bracket would, but supplies you with a larger bearing diameter, so you can ride with the power you want, and a virtually future-proof setup.

Features

  • Material: [cups] aluminum, [bearings] steel
  • Shell Type: BSA
  • Shell Width: 68/73mm
