Garmin Vector Upgrade Kit

This kit converts your existing single-sensing Vector S system into a dual-sensing Vector 2S system. By adding a second sensor to your non-drive side pedal, it allows the system to measure power output from both legs independently, providing a more accurate total power reading and insight into your left-right balance.

The upgrade kit is designed to fit crank arms with a thickness between 12mm and 18mm. Before purchasing, verify the thickness of your specific crank arms to ensure the spindle and sensor housing will mount securely.

While you can install it yourself, it requires basic mechanical knowledge and the correct tools to ensure the pedal spindle is installed to the proper torque specifications. If you are not comfortable working on your drivetrain, a local bike shop can handle the installation quickly.

Yes, once the second pedal is installed, you will need to pair the new sensor with your cycling computer or head unit. You should also perform a static calibration or 'zero offset' to ensure the system is accurately reading your power output.

The system uses a standard 2032 coin cell battery, which typically provides about 175 hours of ride time. Because it is user-replaceable, you can easily swap it out yourself whenever the battery level runs low.

The Vector 2S system is compatible with Look Keo cleats. If you are already using Look Keo cleats with your current Vector S pedals, you will not need to change your setup.
