CX/Gravel Power Meters

Additional CX/Gravel Power Meters Info:

SRM X-Power MTB Power Meter Pedals

The SRM X-Power is one of only two power meter pedals designed for off-road use. Using a standard Shimano SPD cleat, you can use this pedal for cyclocross or gravel. It is available in either a dual- or single-sided version. In addition, because it’s a pedal-based power meter, it is compatible with any bike and can easily be moved between bikes.

Pros: Fits any bike, single- or dual-sided power options
Cons: Dual-sided version is pricey

Garmin Rally XC200 and XC100 MTB Power Meter Pedals

Garmin is the other brand that makes power meter pedals for offroad use. Like the SRM above, the Garmin Rally XC uses a Shimano SPD cleat and is a great cyclocross or gravel power meter. The XC200 is a dual-sided system (measures power in each pedal), whereas the XC100 measures power in the left pedal only. In addition, the Rally features a cool transferable spindle system, which allows you to use the power meter on a road bike as well (conversion kit sold separately).

Pros: Fits any bike, single- or dual-sided power options
Cons: Dual-sided version is pricey

4iiii and Stages Left Crank Arm GRX RX810 Power Meters

These 4iiii and Stages GRX gravel power meters are compatible with all Shimano GRX cranksets including GRX RX600. They replace your left side crank arm and measure left leg power. They are some of our best-selling gravel power meters because they are affordable and easy to install.

4iiii Right Crank Arm GRX RX810 Power Meter

4iiii also makes a right side GRX crank arm power meter. This power meter can serve two purposes: if you have a 4iiii GRX left side crank arm power meter, it allows you to upgrade to a dual-sided crankset. Or, some bike frames cannot fit a left side power meter due to clearance issues with the chainstay. In these situations, this 4iiii right side power meter is a great solution.
