Vector™ 3

Up Your Game

Power is the most reliable way to gauge your performance on any given day, at any given time. Unlike other power meters, Vector 3 has the sensors housed right in the pedals, so it delivers reliable, accurate data on every training session.

Take It to the Next Level

Vector 3 measures total power, cadence and left/right balance as well as advanced cycling dynamics, which helps you tailor your training around your specific weaknesses and strengths to improve your form.

It tracks seating/standing position to determine when and how long you were in each. So, you can gauge position effectiveness, power phase to show how you’re currently producing power in a pedal stroke and platform center offset to show where power is applied on the pedal so you can ensure proper cleat position.

Easy to Install, Transfer and Use

With Vector 3, there are no complex drivetrain or wheel tradeoffs and no external sensors to install.

There are also no pods, so Vector 3 installs like any other pedal — and it’s easy to transfer from 1 bike to another without bike shop assistance.

It offers battery life up to 120 hours.

Easy to Install, Transfer and Use

It tracks seating/standing position to determine when and how long you were in each. So, you can gauge position effectiveness, power phase to show how you’re currently producing power in a pedal stroke and platform center offset to show where power is applied on the pedal so you can ensure proper cleat position.

Seated/Standing Position

You likely have a unique preference for position on the bike during climbs and sprints. Vector can detect and flag riding position (seated or standing) during a ride by comparing forces applied to the pedals. Your compatible Edge cycling computer will then display current position, summaries of how often and how long you have been in the position and power data, all in real time.

After your ride, you can upload your data to Garmin Connect™ online fitness community. There you can view each position, associated cadence and speed, and you can compare time spent seated vs. standing. Even learn how a certain position affects your power output, and analyze climbs and sprints. This detailed data gives you a dialed-in look at your ride and can be useful when determining position effectiveness and identifying tendencies to move positions during particular moments of a ride.

Power Phase (PP)

Power phase provides a valuable description of how you’re currently producing power in a pedal stroke. Vector detects where the leg is generating positive torque in a pedal stroke and where the greatest concentration of positive torque occurs. It also senses the angle at which these forces begin and end and where your concentration of power is produced. If you’re using the dual-sensing Vector power meter, you get to take your analysis one step further and see if there are differences between the left and right leg.

Power phase is measured as a combination of degrees and arc length, with 0 degrees representing the 12 o’clock position and 180 degrees representing the 6 o’clock position. The length of the power phase is measured by the difference between the starting and end angles. For example, a power phase starting angle of 5 degrees and a power phase end angle of 220 degrees would represent a power phase arc length of 215 degrees. With dual-sensing pedals, this information is provided for both your left and right legs. Then you can view where the majority of power is produced using the peak power phase metric (PPP). The default setting is for peak power phase to represent 50% of the power output, but this can be adjusted up or down depending on your preference.

You can view power phase metrics displayed graphically on Edge devices and on Garmin Connect. This makes it easier for you to visualize your pedal stroke.

Platform Center Offset (PCO)

The PCO measurement is calculated by identifying how force is distributed across the pedal platform during the pedal stroke. That means you can view and evaluate where force is applied relative to the center of the pedal platform and what the PCO distribution is over a given period of time. Analyzing this data can help you determine proper bike fit and cleat position. It may also be helpful in preventing injury and rehabilitation.

PCO is measured in millimeters. Positive values (e.g., +6 mm) indicate increased force toward the outside of the pedal, while negative values (e.g., -4 mm) indicate increased force toward the inside of the pedal. You can view this information in graph form on your Edge device. The red line indicates the current 10-second average value and the blue line represents the average for the previous 30 seconds.

Right/Left Balance

The dual-sensing Vector pedals are not only able to measure your combined power output, they can also separate left-leg from right-leg power to let you know if 1 leg is producing more power than the other. In other words, how symmetrically are you pedaling?

Studies show that a large imbalance between the left and right leg force production can cause premature fatigue and even put you at increased risk for injury. That’s why it’s good to know if there’s significant asymmetry, so you can work on improving it. Symmetry means both legs are working equally hard, giving you better efficiency.

Part of Your Connected Bike

Get the most from your training by seamlessly pairing your Vector 3 with compatible Edge cycling computers, ANT+ or Bluetooth-enabled fitness devices¹ — including compatible Forerunner® and fēnix® devices — and Garmin Connect Mobile app. Plus, you can easily update software with any of these devices.

You can also integrate post-ride analysis, data sharing, mapping, route planning and more with Garmin Connect™, Strava and TrainingPeaks.

Use ANT+ connectivity to get stronger by pairing Vector 3 with TrainerRoad. With the TrainerRoad app, you’ll get personally scaled indoor workouts based on power from Vector 3. The indoor training system also has training plans that tell you exactly what to do to achieve your unique fitness and race goals. It’s structured training in its most sophisticated and guided form. Sign up with TrainerRoad to get faster, and train for your first 30 days risk-free.
