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 Whether your frame uses a threaded bottom bracket, Press Fit BB30 or PF30.
When was DUB announced? we could already do this. imagine eye roll from the mountain bike community seeing the changing standards that apparently are imposed 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 bearing life compared to 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 hard pedaling and reliability in all twelve gears.
See you! DUB Cranks do not require major component repairs to operate , this is not so similar to the recently introduced standard how much sooner to 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 tried to fit all the main bottom brackets available in mountain bike frames, there are two types that are not compatible including those equipped with Super Boost rear axles, as well as those which use Cannondale BB30 Ai bottom brackets.
Except for DUB standard GX Eagle DUB cranks are perfect for the everyday racer which requires 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 a much lower cost than carbon offerings such as XO1 and XX1. This particular version works with the proven 12 x 142 mm rear axle distance which can be found on highway and universal machines.
