The SRAM Quarq Rival Power-Upgrade AXS WIDE is a spider-based power meter designed to seamlessly integrate with SRAM’s Rival AXS WIDE cranksets. Built around Quarq’s proven measurement technology, it delivers reliable, dual-sided power data by capturing total output at the crank spider, giving you consistent readings regardless of which leg is doing more work. This makes it an ideal upgrade for riders who want to move from riding by feel to training with accurate, repeatable numbers that help guide intervals, pacing, and long-term progress.
Engineered for modern road, gravel, and all-road bikes using SRAM’s WIDE standard, this power upgrade maintains the clean look and shifting performance of your existing drivetrain. It communicates wirelessly with popular bike computers and training apps via standard protocols, so pairing and recording your rides is straightforward. With a durable, weather-resistant design and long battery life, the SRAM Quarq Rival Power-Upgrade AXS WIDE is built to handle everyday training, racing, and adventure riding while giving you the data you need to ride smarter and faster.
