What does Durable Unified Bottom Bracket, or DUB for short, mean? the latest step forward in SRAM crank technology combines all major bottom bracket standards with a new 28 spindle diameter 99 mm compared to previous 30 and 24 mm diameter spindles used by SRAM. . Ultimately this means that the GX Eagle DUB crankset is compatible with almost any mountain bike regardless of whether your frame uses a threaded bottom bracket press fit, BB30 or PF30.

When DUB was first announced we could already imagine how the mountain bike community would roll their eyes seeing how standards change every year. However, just hear us out. before you leave. SRAM is fully focused on increasing bearing life and DUB sealing , and then designed the spindle diameter to meet these requirements what does it mean that it is ready to ride in wet and poor conditions. SRAM was able to develop a new crankset as light and stiff as cranks with 30mm spindles but providing increased wear resistance of bearings like 24mm spindles. It's a really simple concept which takes SRAM Eagle DUB cranks to the top of the market thanks to the optimal combination of lightness efficiency rigidity and reliability in all twelve gears.

Since DUB Cranks do not require major component overhauls to operate this does not look like the recently introduced standard but rather the next step in SRAM's ever-evolving line of drivetrain components. Certainly for this crank to work you will have to purchase a new bottom bracket specifically for the DUB but really it's a small compromise given the perfect combination of lightness performance and bearing life. Although SRAM has tried its best to meet all major bottom bracket standards , there were two types that were not compatible including frames with Super
Boost rear ends, as well as frames using the Cannondale BB30 Ai standard.

Beyond the DUB standard, the GX Eagle DUB cranks are ideal for the everyday racer who require reliability and efficient pedaling but who is not too concerned with counting every last gram. It is made of 7000 series aluminum which provides an optimal strength-to-weight ratio and lower cost than carbon offerings such as XO1 and XX1. This particular version runs exclusively with the BOOST 12 x 148mm rear axle spacing and pairs nicely with SRAM's Eagle 12-speed drivetrain components.
