All MTB Power Meters

Additional All MTB Power Meters Info:

All these mountain bike power meters are accurate to within 1.0 – 2.0% and are made to handle the rigors of off-road retain. Some measure left leg power while others measure both legs. On every power meter’s product page, you can find this information and much more. Here is a quick overview of each brand’s MTB power meters:

4iiii

4iiii makes crank arm power meters for Shimano cranksets. Therefore, they currently offer left-side crank arms for Shimano XT 8100/8200, XTR 9000 and XTR 9100. The power meters are affordable, easy to install and feature a 3-year warranty. However, most only measure power from the left leg (compared to some other power meters that measure both legs).

Garmin

Garmin makes power meter pedals. For MTB, they have the Rally XC pedal which uses Shimano SPD cleats. The Rally XC200 is a dual-sided power meter whereas the XC100 is a single-sided version. These pedals are a bit on the larger side for an MTB pedal, but they were built to handle tough off-road terrain.

power2max

power2max makes power meter spiders. These power meters bolt to your crank arm and you then attach a chainring to the power meter. They measure power from both legs, are accurate and reliable. They offer mountain bike power meter spiders for SRAM, Race Face, Praxis, Cannondale, ROTOR, Shimano and e*thirteen cranksets.

Quarq

Quarq’s MTB power meter is the Quarq XX1 Eagle DUB Power Meter. It is usually sold as a complete crankset – power meter spider, crank arms and chainring. It measures power from both legs and features carbon crank arms. This power meter requires a SRAM DUB bottom bracket.

ROTOR

ROTOR makes crankset power meters. This means you replace your existing crankset with the new power equipped version. For MTB, ROTOR has the 2INpower MTB Power meter and the INpower MTB Power Meter. The main difference is the 2INpower measures power from both legs, whereas the INpower measures left leg power only. These are great, solid units, however the 2INpower is a bit on the pricey side. They also offer the INspider which is a spider based power meter that bolts to ROTOR KAPIC Carbon crank arms.

SRM

SRM also makes crankset power meters. They offer the Origin MTB Power meter which measures power from both legs. One thing that is nice about the SRM is they are highly configurable. You can order it with different crank arms (several versions of carbon as well as aluminum) and different spindle sizes. SRM power meters are the most expensive options, however the company enjoys a solid reputation, as they have the most experience of any power meter manufacturer.

Stages

Stages makes crank arm power meters, however unlike 4iiii, they offer MTB power meter crank arms for a range of MTB cranksets. This includes power meters for SRAM, Race Face, Cannondale and Shimano. They also offer entire cranksets for Shimano XT 8120 and XTR 9120.

Velocomp

Velocomp makes handlebar-mounted power meters. These don’t have the accuracy of a direct force power meter (like the ones above). However, they are affordable, can be used on any bike and can be moved between bikes, which are some big advantages most other power meters can’t claim.
