ROTOR 2InPower DM crank ( no chainrings )

$ 1.400,00

Knowing your strengths is helpful, but knowing your weaknesses is like mining for gold  because if you can measure them, you can improve them. 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 haven 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. These eight strain gauges might seem a touch excessive, as most leading power meters stop at five, but we find that the increased number reduces the chances of external conditions, like rapid changes in temperature, adversely affecting accuracy.  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.
