The Garmin Vector 3S Single Sensing Power Meter provides single sided power metering from a high-quality, aero power meter pedal. The new Vector 3S pedal is a redesigned, honed and cost effective means of equipping you with an accurate and precise representation of your performance in training. 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 the sensors housed right in the pedals, so it delivers reliable, accurate data on every training session.Take It to the next levelVector 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 useWith Vector 3S, there are no complex drivetrain or wheel trade-offs 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 one 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.Garmin Vector 3S Single Sensing Power Meter FeaturesInstalls like any other pedal and quickly transfers between bikesReports cadence and total power (watts)Easily upgrades to dual-sensing systemFully integrates with Garmin cycling ecosystem for data analysisAllows for easy updates via compatible Edge® cycling computers, ANT+® connectivity or Bluetooth®-enabled fitness devices1 and Garmin Connect™ Mobile appBattery life: up to 120 hoursTwo versions of Vector 3 are available - dual sided system has 2 power pedals, and S version stands for single sided where measurement is calculated through one pedal and a second dummy pedal supplied
