  • JUST THE FACTS:

    The BBInfinite PF30A 83mm bottom bracket works with both SRAM DUB Wide 1X and SRAM DUB Ai road crank sets. If you are running DUB in a SuperSix EVO SE/CX frome this is the bottom bracket for you. The DUB SL and DUB Wide 2X cranks are not compatible with the frame. All of our 83mm BB modules ship with the special press tools and retaining compounds you'll need. All you need to install is a press for this gravel and road bike bottom bracket.

    MORE THAN EXTREME SPEED AND SILENCE:

    BBInfinite bottom brackets for SRAM DUB crank sets maintain optimal chain-lines for crisp, consistent shifting and drivetrain performance while dishing out trouble-free mile after trouble-free mile. From the gorgeous, high-luster of our TypeII MilSpec hard anodized finish to the sculpted lines of our One-Piece design that unitizes the bottom bracket structure to eliminate all potential creaks before they start, every aspect of our arcitecture fuses beauty with durability and performnace.

     

    Our SRAM DUB optimized design is set to the widest stance the crank set allows while ensuring that interfaces between crank arm splines and spindle splines have maximum engagement and Q-factor is set as narrow as possible.

    POWER METER FRIENDLY

    All BBInfinite bottom brackets for SRAM DUB crank sets are 100% compatible with all crank-based power meters. Our flange-less drive-side arcitecture ensures zero interference with protruding power-meter back plates such as those found on Quarqs and SRMs.

    WHY DO BBINFINITE BOTTOM BRACKETS SPIN LIKE CRAZY?:

    Bicycle frame bottom bracket shells are notoriously misaligned, inconsistent, and out of round, and so it’s inadvisable to use the bike frame as the primary aligning member for bottom bracket bearings. Yet, that’s what our multi-piece bottom bracket competition does, and this explains why their systems frequently fail prematurely and creak.

    A BBInfinite OPD (One-Piece-Design) bottom bracket module is a CNC precision-machined hub---like the front wheel hub on your bike---that you press into your frame. And just like your trouble-free wheel hub, BBInfinite OPD bottom brackets have perfectly aligned bearings regardless of your frame’s BB shell alignment and tolerances. Perfectly aligned bearings are essential for thousands of miles of trouble-free use and extreme spin performance.

    WHAT KEEPS BBINFINITE BOTTOM BRACKETS FROM CREAKING?

    BBInfinite OPD is the answer for creaking bottom bracket problems as well. Pedaling forces conspire to lever, and rock, and eventually work multi-piece systems loose. The unitized nature of BBInfinite OPD cancels these forces out entirely, which means creaking has no place to start in the first place. It really is that simple.

    INSTALLATION IS A SNAP WITH BBINFINITE:

    Every BBInfinite 83mm BB module ships with the special press tools, hardware, instructions, and the retaining compound you need to get the job done correctly with ease and confidence. All you need is the press for this road bike bottom bracket. If you need a press, check out our Master Tool Press.
