The GX Eagle Transmission DUB crankset gives no-nonsense riders a no-compromise balance of form and function. It’s the crankset where pure performance and measurement meet optimal value. Its two independently removable composite bashguards add durability and allows riders to manage scuffs and scrapes that come with the territory. The power meter provides riders with accurate, live power data, and is integrated through what SRAM call "DUB-PWR" - a unique design that elegantly houses Quarq power measurement inside the DUB crank spindle itself. Measuring left-side power to calculate total Watts, it’s subtle, lightweight, compatible with any chainring setup, and boasts unbeatable battery. No-compromise, no-fuss data delivery with robustness in mind.
The SRAM GX Eagle Transmission DUB crankset power meter is built for riders who want serious performance data without unnecessary complexity. Designed around SRAM's latest T-Type ecosystem, it delivers a tough, dependable crankset with clean integration and excellent value. The Quarq power measurement is housed neatly inside the DUB spindle using SRAM's DUB-PWR design, keeping the system subtle, lightweight and well protected, while the independently removable composite bashguards help defend against trail damage and keep the crankset looking fresher for longer.
