Up Your Game

Ride stronger, smarter, connected with the Vector 3S pedal-based power meter. As you strive to beat your personal best on your next race or Gran Fondo, power is the most reliable way to gauge your performance on any given day, at any given time. Unlike other power meters, Vector 3S has a sensor housed in the left pedal, so it delivers reliable, accurate data on every training session.

Take It to the Next Level

Vector 3S is an affordable way for you to receive power data and take your training to the next level. As a single-sensing system, it uses the forces detected on the left pedal to measure cadence and approximate total power, and it’s easy to upgrade later to the dual-sensing system.

Easy to Install, Transfer and Use

With Vector 3S, there are no complex drivetrain or wheel tradeoffs and no external sensors to install. There are also no pods, so Vector 3S installs like any other pedal — and it’s easy to transfer from 1 bike to another without bike shop assistance. Plus, its sleek design and improved stack height provide greater cornering clearance and smarter ergonomics, and its precision stainless-steel spindle and composite pedal body have been engineered and tested to withstand years of use. It offers battery life up to 120 hours.

Get the most from your training by seamlessly pairing your Vector 3S 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.
