SRAM Force E1 Dub Left Crank With Power Meter

The SRAM Force AXS E1 DUB Left Crank with Power Meter integrates a spindle-based power meter into a hollow carbon fiber left crank arm. Designed to measure left-leg wattage for data-driven training, it doubles the reading to estimate total power while maintaining a lightweight, stiff, and durable profile. Built for road and gravel, the carbon crank delivers efficient power transfer, while the DUB spindle provides a compact, robust sensor solution that protects electronics from the elements. With a long-lasting battery and an IPX7 waterproof rating, it is prepared for training and racing in varied conditions. This upgrade helps riders pace efforts, execute structured workouts, and track fitness gains without adding unnecessary weight or complexity to the existing force AXS setup.
