Garmin Power Meters

Image of Garmin logo

Garmin is on the third version of its popular power meter pedal, the Garmin Vector 3. The Vector 3 comes in two versions: a dual-sided version (Vector 3) and a single-sided version (Vector 3S). With both versions, you get both a left and right pedal. However, the V3 has a power sensor in each pedal and can therefore measure both left and right leg power. The V3S has a senor in just the left pedal and measures left leg power only. Garmin power meters feature an ultra-slim pedal body, Bluetooth SMART, easy set-up and Garmin’s Cycling Dynamics pedaling metrics.

Additional Information:

Installation

When it comes to installation, it doesn’t get much easier. Both the Vector 3 and 3S install just like a normal pedal – no torque settings or special tools required. Installation can be done in a matter of minutes. This also allows them to be moved between bikes quickly and easily.

Weight

The Garmin power meters weigh 155 grams per pedal. This is within a few grams of many of the other popular pedal-based power meters.

Power Measurement

As previously discussed, the Garmin Vector 3 measures both legs and also measures independent left/right leg power. The Vector 3S measures left leg power and doubles it to approximate total power. This is how all single-side 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 a LR44/SR44 battery. This battery is similar to, but not exactly the same, as the CR2032 battery used by other power meters. Battery life is 120-150 hours, 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.
