SRAM s Rival AXS E1 DUB Power Meter Direct Mount Crankset brings integrated power measurement to a robust, lightweight, and efficient design. It combines aluminium arms, direct mount chainrings, and a spindle-based power meter to deliver accurate data without compromising shifting or ride quality. With wide compatibility, long battery life, and weather-sealed reliability, it delivers dependable performance for data-driven training.Key Features and Benefits:Spindle-based power meter that measures left-side output: This design calculates total power based on one side, reducing complexity while still providing reliable watt data. It offers a cost-effective way to track training loads and performance improvements.Integrated AAA lithium battery with 400+ hour runtime: The long-lasting, user-replaceable battery ensures minimal maintenance and consistent operation. This means fewer interruptions and more time spent training.Lightweight design, adding less than 40g to standard crankset: By limiting the weight increase, the system maintains a responsive and efficient ride feel. This preserves bike handling and climbing performance.DUB bottom bracket compatibility: The DUB interface simplifies setup while improving bearing durability. This results in a smooth, low-maintenance ride with longer service intervals.IPX7 waterproof rating (1m for 30 minutes): The power meter is sealed against water intrusion, protecting internal components. This enhances reliability across all weather conditions.Direct mount aluminium chainrings with X-Range gearing: Integrated rings provide crisp, consistent front shifts while supporting wide gear coverage. This improves cadence control and overall efficiency.Cyclists seeking consistent and accessible power data will benefit most from this crankset. The spindle-based sensor offers a smart balance of accuracy, simplicity, and value. SRAM s one-piece chainring structure maintains drivetrain stiffness and precise shifting, while the long-life battery and waterproof design ensure it performs across a season of varied conditions. It s made to fit seamlessly into modern 12-speed road setups using DUB bottom brackets.Equip your training and racing setup with a crankset that delivers essential data without trade-offs in weight, shift quality, or durability. It's built for performance you can trust every ride.Specification:Speeds 12BB Compatibility All SRAM Road DUB BBsChainring Size 46/33T, 48/35TCrank arm length 160mm, 165mm, 170mm, 172.5mm, 175mmChainline 45.0mmBB Spindle Interface DUBChainring material AluminiumGuard No GuardBolt Circle Diameter (BCD) Direct Mount (DM)Crank arm material AluminiumColour (Crank arm) BlackPower meter YesPower Meter Type Spindle
