Upgrade your Vector 3S to a dual-sensing power meter, and step beyond watts to see exactly how your pedaling style generates the force that moves you.When paired with Vector 3S, the upgrade pedal completes the Vector power meter system, providing left/right balance data and cycling dynamics. With the new podless design, it installs like any other bike pedal.Revolutionary cycling dynamics show you exactly where you’re generating power throughout the pedal stroke. See where you apply force on the pedal to ensure proper cleat position. The upgrade pedal also tracks when and how long you were seated versus standing so you can gauge position effectiveness.
