About the ROTOR INpower 3D+ – Left Side Only

If you already have a ROTOR 3D+ crank, you can add power to your bike by buying this ROTOR INpower 3D+ – Left Side Only crank arm.  The ROTOR INpower 3D+ places its 4 strain gauges inside the axle, which is attached to the left crank arm, so all you need to do is remove your existing left arm and install this one – and you have ROTOR power!

Another advantage to the axle-based design is that it means the critical components of the power meter are safe from impact, dirt and water, plus it allows you to maintain your bike’s sleek, elegant aesthetics.

This ROTOR power meter features INpower’s TORQUE 360 and OCA pedal analysis, which allows you to define your pedal performance and apply it to Q-Rings to reach your full potential. The ROTOR INpower 3D+ is powered by a AA battery and records your power readings via your ANT+ head unit.
