Garmin Vector 3S Single-Sensing Power Meter
Single-sensing Pedal-based Power Meter
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.
The Vector 3S features an easy install like any other pedal and quickly transfers between bikes, reports cadence and total power, fully integrates with Garmin cycling ecosystem for data analysis, and allows for easy updates via compatible Edge® cycling computers, ANT+® connectivity, or Bluetooth®-enabled fitness devices¹ and Garmin Connect™ Mobile app.

Garmin Vector 3S Features
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 a battery life of up to 120 hours.
