Eliminate battery dead zones and mid-race power blackouts across grueling multi-day training camps and full-distance triathlons. The ArcRayo ARS Pro Max is custom-engineered for ultra-endurance triathletes and Gran Fondo specialists who require non-stop telemetry. Doubling the power cell capacity to an astonishing 600 hours of active riding time, this spider power meter delivers uninterrupted precision from pre-season volume blocks to the championship finish line.
Despite packing industry-leading battery longevity, the ARS Pro Max maintains a razor-thin chassis in the mid-80-gram range—adding practically negligible weight while unlocking unprecedented endurance. Integrated real-time temperature compensation neutralizes sudden coastal microclimate drops and baking tarmac headwinds, ensuring your target wattage numbers remain rock-solid when fatigue sets in.
With comprehensive cycling dynamics—including real-time power, cadence, left/right pedaling balance, and pedal smoothness—the ARS Pro Max feeds essential pacing data to your Garmin, Wahoo, or TT aero cockpit display via ANT+ and Bluetooth. Complete with IP68 stormproof sealing and a 30-month factory warranty, it is the definitive power management anchor for long-course athletes.
