Garmin Power Meters

Garmin has been making power meter pedals for nearly a decade now. Their current pedal, the Garmin Rally, was released in 2021. Redesigned from the ground up, the Rally has proven to be nice improvement over the previous version (Garmin Vector) is now one of our best-selling power meters.  The Rally comes in three versions: RK (LOOK Keo cleat), RS (Shimano SPD-SL cleat) and XC (Shimano SPD cleat). All three models feature a dual-sided version as well as a single-sided version. Garmin power meters are accurate to +/- 1.0%, use an ultra-slim pedal body and Bluetooth SMART. They also feature Garmin’s Cycling Dynamics pedaling metrics.

Additional Information:

Installation

When it comes to installation, it doesn’t get much easier. The Rally installs just like a normal pedal – no torque settings or special tools required. Installation can be done in a matter of minutes. This also means you can move them between bikes quickly and easily.

Weight

The Garmin Rally RS and RK power meters weigh 160 and 163 grams per pedal, respectively. This is within a few grams of many of the other popular pedal-based power meters. The Garmin Rally XC is built to withstand the rigors of off-road riding, so it’s understandable more robust. It weighs 222 grams per pedal.

Power Measurement

As previously discussed, all three models feature a dual-sided version (200) and a single-sided version (100). With all versions, you get both a left and right pedal. However, the dual-sided versions have a power sensor in each pedal. Therefore, they can measure both legs as well as independent left/right leg power. The single-sided versions have a senor in just the left pedal and measure left leg power. The power meter doubles left leg power to approximate your total power. This is how all single-sided power meters work.

Special Features

In addition to possessing all of the benefits of a pedal-based system (easy installation, compatible with all bikes, etc.), the Garmin power meters have a few unique features. It’s indeed the slimmest of all power meter pedals, much resembling a standard road pedal. In addition, it provides access to Garmin’s suite of advanced cycling dynamics data.

Batteries

These power meters use LR44/SR44 (x4) or CR1/3N (x2) batteries. This battery is similar to, but not exactly the same, as the CR2032 battery used by other power meters. Battery life is up to 120, which we note is longer than any other pedal.

Communication Protocol

Like most power meters that are available today, Garmin power meters are compatible with both ANT+ and Bluetooth SMART devices. This allows you to use the power meter with virtually any headunit, including smart phones. It also allows them to easily pair with training apps like Zwift.

Accuracy

These units are accurate to within +/- 1.0%. This is on par (to slightly better) than the majority of other power meters on the market.

Cadence Detection

Like most power meters, the Garmin power meters use an accelerometer, housed inside the pedal body, to measure cadence. This ensures accurate cadence measurement. It also means you don’t have to worry about attaching a magnet to your frame.

Warranty

Garmin power meters come with a two-year manufacturer’s warranty.
