Sram DUB
$70.00 CAD
Take The DUB
Simplify your drivetrain without compromising on performance. The Sram DUB (Durable Unified Bottom Bracket) system was engineered to solve the industry-wide headache of conflicting spindle standards. By unifying the spindle diameter to a single 28.99mm spec, Sram has created a platform that offers the stiffness of a 30mm spindle with the superior sealing and longevity of a 24mm system.
Whether you are building up a new Winspace or refreshing your favorite ride at Alegro Cycles, the DUB system is the "set it and forget it" solution. Its redesigned Gutter Seal Technology significantly improves protection against the elements, ensuring that your bearings spin smooth and silent whether you're mid-sprint at Midweek Crit or grinding through a rainy winter commute.
-
Universal Spindle Standard: One crankset now fits every frame interface; from threaded BSA to PressFit 86 and BB30. Simply by choosing the correct DUB bottom bracket.
-
Gutter Seal Technology: Features high-grade internal seals that drastically improve weather resistance and bearing life compared to previous designs.
-
Engineered for Longevity: Better integration between the crank, spindle, and bearings results in a stiffer, more durable interface that resists creaking.
-
Lightweight Efficiency: Significantly lighter than previous bottom bracket systems while offering improved power transfer for every watt you put into the pedals.
-
Consistent Performance: Designed for easy installation and removal, making routine maintenance at the shop or in your home garage a breeze.
Technical Note: Sram DUB bottom brackets are interface-specific. Please ensure you select the correct model for your frame (e.g., BSA, PF92, BB30, or PF30) to match your Sram DUB crankset.
