Garmin Vector 3S Power Meter Road Keo single-sided system


Free UK Delivery on orders over £100

This single-sided system measures the power output from just one pedal, and is the most economical way to get into the Vector system. An upgrade kit is available should you wish to add dual-sided measurement at a later date.

No More Pods!

The previous generation of Vector pedals have long been one of our favourite ways to measure power output. But they were admittedly a bit fiddly to install, with the separate "pods" complicating the process and requiring a very precise torque.

For us, one of the headline features of the Vector 3 is no more pods - the pedals are a fully integrated unit, making installation (and swapping between bikes) a breeze.

The pedals themselves have been slimmed down, providing better clearance when cornering, and lower stack height to get your foot closer to the centre for improved ergonomics.

With accuracy of +/- 1% these really are one of the easiest, most effective ways to gather precise power data.

Precise, Versatile, Useful

We're fans of pedal-based power measurement, not least because it makes it so easy to swap between bikes. Far superior to hub-based systems which limit you to one (expensive) wheelset.

Now you can easily measure power not just on race day, but during training, and even when on the indoors trainer (they work particularly well with our favourite, the Wahoo Kickr).

This is even more true with these latest Vector 3 models, which no longer rely on fiddly "pods" and can be quickly and easily swapped with a simple spanner, no need for pro mechanic involvement!

Build quality is fantastic, with a strong, durable stainless steel axle and composite body. Based on the classic, widely available KEO pedal system they'll work with any standard three-bolt road cycling shoes (a set of cleats are included, but if you already use KEO they'll be fine with your existing cleats too).

Power measurement is the most reliable, consistent way to measure your performance on any given day - opt for the Vectors and you can be sure you'll always have supremely accurate power data available.

Why choose the Vector?

With the Vector 3 dual-sensing system, you get the valuable ability to see right and left leg power independently. 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 centre offset to show where power is applied on the pedal so you can ensure proper cleat position. Each metric can be viewed on compatible Edge® cycling computers and the Garmin Connect™ Mobile app.
