This is the best track power meter out there. No question about it. With fully independent left/right power readings, you can dial in your pedal stroke and make the most of every training session. Our dual-sided 2INpower measures power individually in each leg to provide precise data about balance and power output in order to demonstrate where improvements can be made to pedaling performance, so you can harness the information and push yourself to the podium.

As the name suggests, 2INpower evolved from ROTOR's INpower, with the power meter tucked neatly inside the crank axle that measures power in the left leg. However, on the 2INpower, two additional sets of strain gauges have been placed in the right crank arm, which offer precise measurements of power exclusively in the right leg, balancing out your drive and non-drive side with accurate readings, so you can hone your power in both legs. The eight strain gauges reduce the chance of adverse effects from external conditions like rapid changes in temperature or barometric pressure.  We opt to house the strain gauges tucked neatly in the crank axle, while electronics stay spindle-bound for protection against the elements. 

2INpower features both Bluetooth Smart, and ANT+ functionality, as well as a built-in rechargeable battery for easy charging between rides. Please note that chainrings are sold separately.
