Garmin is on the third version of its power meter pedal, the Garmin Vector 3. The Vector 3 measures left and right leg power whereas the Vector 3S measures left leg power only. Garmin power meters feature an ultra-slim pedal body, Bluetooth SMART, easy installation and Garmin’s Cycling Dynamics pedaling metrics.
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. This also allows them to be moved between bikes quickly and easily.
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.
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. It is consistent with how all, left-side power meters operate.
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, longer than any other pedal.
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.
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.
Like most power meters, the Garmin power meters use an accelerometer, housed inside the pedal body, to measure cadence. This means you don’t have to worry about attaching a magnet to your frame.
Garmin power meters come with a two-year manufacturer’s warranty.
