This SRAM Power Meter Crankset combines advanced aluminum engineering with accessible, high-performance power measurement. The lightweight and accurate spindle-based DUB-PWR unit is neatly integrated within the DUB spindle, providing a clean look while measuring left-side power to calculate total watts. This design adds less than 40g to a standard crankset, ensuring your data collection doesn't come at the cost of significant weight.

Built for durability and ease of use, the unit features a user-replaceable AAA lithium battery with a lifespan of over 400 hours—enough to power a full season of riding. The crankset utilizes SRAM's X-SYNC wide-tooth, narrow-tooth chainring technology for maximum chain control and is rated IPX7 waterproof, allowing for reliable performance in the toughest conditions.
