The SRAM Rival XPLR AXS E1 Power Meter is engineered for riders who measure performance not just in watts, but in the miles of discovery those watts make possible. Designed specifically for the mixed-surface demands of gravel, all-road, and endurance exploration, it brings precision power measurement, rugged reliability, and wireless simplicity to the heart of SRAM’s XPLR ecosystem. From high-tempo training to multi-day adventures, the Rival XPLR Power Meter transforms how riders understand and refine their effort — one accurate, data-driven ride at a time.

Built on the proven Quarq D-Zero power platform, the Rival XPLR AXS E1 measures total output from both legs via integrated spider-based strain gauges. This placement ensures consistent, dual-sided accuracy — ±1.5 % in all conditions — without interference from pedal balance or drivetrain friction. The temperature-compensated system maintains precision whether you’re climbing through alpine cold or hammering across sun-baked gravel. Encased within a fully sealed housing, it’s built to handle mud, rain, dust, and vibration with IPX7 waterproof certification. Every watt recorded is true to your effort, free from drift, lag, or compromise.

The direct-mount design eliminates unnecessary interfaces, reducing weight while improving stiffness and alignment between chainring and crank spider. The system pairs with 1× XPLR drivetrains, optimized for chainrings between 38 T and 46 T, offering a gearing range ideal for gravel speed and climbing efficiency. The narrow-wide tooth profile enhances chain security over rough surfaces, while the precisely machined tooth geometry ensures silent, friction-free engagement. Each power meter unit comes pre-calibrated from SRAM’s Colorado facility, ensuring laboratory-grade accuracy the moment it’s installed.

At the heart of its simplicity lies the AXS wireless platform. Setup is instant — pair through the SRAM AXS app, perform zero-offset calibration, and connect seamlessly to any ANT+ or Bluetooth-enabled head unit. The app provides firmware updates, battery status, and ride analytics integration for Strava, TrainingPeaks, and other performance software. The system runs on a standard CR2032 coin cell battery, delivering over 200 hours of ride time and tool-free replacement in seconds. SRAM’s refined electronics ensure consistent transmission even in remote terrain, eliminating dropouts and latency for uninterrupted data tracking.

The crankarms themselves are constructed from forged aluminum, providing a perfect balance of stiffness, strength, and cost-efficient performance. The wide Q-factor and DUB spindle interface ensure compatibility across road, gravel, and adventure frames. The satin-finished arms mirror the minimal design language of the Force and Red series, with understated graphics that complement any modern build. Despite its focus on durability, the Rival XPLR AXS E1 remains impressively light, adding only a marginal increase over the non-meter version — a testament to SRAM’s integrated engineering philosophy.

Every structural element of the Rival XPLR AXS E1 Power Meter reflects SRAM’s gravel-first approach: a unit that can handle corrugated washboard climbs, high-torque accelerations, and endless vibration without calibration drift. The wide temperature range and sealed construction make it ideal for multi-climate expeditions and everyday training alike. Riders can rely on consistent data from one season to the next — a true “install and forget” component built to withstand the rigors of exploration.

On the road — or far off it — the Rival XPLR AXS E1 Power Meter enhances your ride without demanding attention. The Quarq measurement system disappears into the crankset’s design, adding virtually no noise or mechanical interference. Its integration with the AXS platform means shift data, gear selection, and power metrics can be viewed together in real time, creating a complete performance ecosystem tailored to how you ride. The result is a cleaner cockpit, simpler setup, and precise insight into how effort translates into speed and efficiency over every mile.

SRAM designed the Rival XPLR AXS E1 to democratize power measurement for gravel and endurance cyclists — to bring professional-grade technology to real-world conditions. It combines the precision of a lab instrument with the toughness of a backcountry tool. Whether used to pace a century ride, fine-tune endurance training zones, or simply understand how terrain shapes effort, it turns feedback into foresight — data that fuels better decisions, smoother pacing, and ultimately, faster, more confident rides.

Lightweight, connected, and built to endure the chaos of gravel, the SRAM Rival XPLR AXS E1 Power Meter represents the new standard for performance measurement off the beaten path. It’s not just a tool for training — it’s the gateway to understanding your ride on a deeper level. Every climb, sprint, and steady-state grind becomes part of a clear, reliable picture of your performance. When precision meets exploration, insight becomes the most powerful advantage of all.
