Assioma PRO MX-1 is the ultimate pedal-based SPD power meter for MTB and gravel with power sensor on the left pedal only. These MTB power meter pedals offer full SPD compatibility and fit any crank arm, oval or round chainrings, and crank boots. The Favero Assioma PRO MX-1 power meter pedals can be installed and swapped between bikes like any other pedal, easily and without special tools. Pair it with your bike computer or smartphone via Bluetooth and ANT+. There is no risk of battery-related power dropouts as all the electronic components and the integrated rechargeable battery are safely stored within an extremely compact and resistant spindle. The aluminum 6061-T6 pedal body is extremely robust and light, ready for all types of terrain. The SPD-compatible clipless system features a surface hardness of up to 800 HV, ensuring that the power meter pedal is as resistant to shocks as never seen before. Assioma PRO MX-1's special IAV Power System fully exploits an integrated three-axis gyroscope to take into account every pedaling variation and factor this into every power calculation, delivering +/-1% accuracy and consistent power data every single time. Recharge your pedals simultaneously with our magnetic system and enjoy more than 60 operational hours with a single charge.
