FAQs
Yes — it’s widely considered the most accurate and durable MTB SPD power meter for XC, gravel, and cyclocross riders.
It maintains ±1% accuracy even on rough terrain thanks to IAV Power technology.
MX-2 is dual-sided; MX-1 is single-sided. MX-2 gives more detailed data for training.
Yes — crank power meters often fail on bumpy terrain. Pedal-based sensors are more consistent off-road.
Yes — they work with Shimano SPD cleats like SH51 and SH56.
160 hours per charge — ideal for adventure rides and races.
Yes. The PRO MX-2 is designed specifically for off-road disciplines like gravel racing, XC, marathon MTB, and cyclocross. Its SPD platform and rugged pedal body make it one of the most versatile SPD power meter pedals for mixed-terrain riding.
Riders often find the MX-2 more durable in muddy conditions and more accurate at low cadences on steep climbs. Garmin XC200 offers more ecosystem features, but the MX-2 wins in value, off-road durability, and long-term accuracy according to many rider reviews.
Yes. Unlike many crank-based power meters, the MX-2’s IAV (Instant Angular Velocity) system maintains ±1% power accuracy even with oval chainrings, which is a major advantage for MTB riders who prefer oval rings for climbing and traction.
It’s recommended but not mandatory. A quick zero-offset calibration ensures the most accurate power readings—especially if the temperature has changed or if you’ve recently switched the pedals to a different bike.
