    DUB BSA Bottom Bracket

    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.

    • Simplify bottom bracket standards with this handy BB
    • Threads into English BB shells to use with DUB cranks
    • Wide 28.99mm bearing diameter increases stiffness
    • Steel bearings are smooth rolling and durable


    • Familiarity: I've put it through the wringer
    • Fit: True to size

    It works the way it supposed to, easy installation. Bought it to complete a full Sram GX Eagle group set.


    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    It looks cool on my bike. No issues. Bought it for the GX groupset.

    Will the BB work with a NX group set?

    New standard will be the new benchmark

    • Familiarity: I've put it through the wringer

    more protection against grime, balance of durability and crank spindle stiffness. the new DUB standard is going to be on a lot of bikes. At competitive cyclist we are even spec'ing our closeout package builds with dub BB's so that customers are getting the best performing and newest stand from a leading components company.

    So Far So Good

    • Familiarity: I've used it once or twice and have initial impressions

    For compatibility reasons I ended up with this BB but installation is easy, seems to come with the right spacers and so far seems pretty solid. I have yet to get enough mileage in to see how the bearings hold up but guessing they will be similar to past SRAM BB’s I have used.
    Solid product at a solid price point so I am happy so far. Cranks are rolling smoothly.

    Seems pretty good so far

    • Familiarity: I've used it several times

    While I haven't been able to test the long term durability of this BB, it seems like it should be just as durable as previous sram BB's, which is pretty good in my experience. The DUB standard is pretty simple and the spacers are easy to sort out as well with included instructions.
