About the ROTOR INpower REX 2 – Left Side Only
If you already have a ROTOR REX 2 crank, you can add power to your bike by buying this INpower REX 2 Left Side Only crank arm. The ROTOR INpower REX 2 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.
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.
INpower’s TORQUE 360 and OCA pedal analysis allows you to define your pedal performance and apply it to Q-Rings to reach your full potential. The ROTOR INpower REX 2 is powered by a AA battery and records your power readings via your ANT+ head unit.
