Quarq reliability at Rival price

Quarq has been the power meter of choice for WorldTour teams for years — the brand's reputation for accurate, durable crank-based power measurement is well established. The Rival AXS Power Meter brings that same technology to the Rival groupset tier, removing the price barrier that previously kept quality crank power meters out of entry and mid-level builds.

Fit and compatibility

Designed for compatible SRAM Rival AXS cranksets — confirm crank model and compatibility before ordering. Pairs with ANT+ and Bluetooth head units. Tune Cycles can install and calibrate as part of a drivetrain or upgrade service.
