Power is the most reliable way to gauge cycling performance on any given day, at any given time. Vector 2 revolutionizes how power is measured and how cyclists get that power data. Unlike other power meters, Vector 2 measures power at the pedal, where force is applied. It’s a direct-measurement power meter that delivers reliable, accurate data. And because the force sensors are housed in each pedal, Vector 2 gives you the unique ability to see right and left leg power independently.
