Garmin Vector S to Vector 2S Power Meter Upgrade Kit Size 12 15mm

Upgrade from a single sensing Vector S pedal based power meter to a single sensing Vector 2S system. Available to fit both standard 12 15 mm and large 15 18 mm crank arms, upgrading allows cycling enthusiasts to take that next step in measuring and monitoring their power output and pedaling style. Easy to Buy, Install, Own Upgrading Vector is easy. You can install it yourself in minutes. There's no need for a mechanic, or no downtime while your bike is in the shop. There are no complex drivetrain or wheel tradeoffs, or no external sensors to install. Behind the Watts Vector works by measuring the deflection in the pedal spindle as you pedal. By comparing that measured deflection to a factory calibration, Vector can determine how much force you're applying to the pedal. It measures a few hundred times per second. Built in accelerometers also measure your pedaling cadence. The force sensor and related electronics are permanently and securely sealed within the pedal spindle.
