About the ROTOR INpower REX 1.2 Crankset

The ROTOR INpower REX 1.2 places its 4 strain gauges inside the axle (hence the name ‘INpower’). The INpower uses ROTOR’s 30mm UBB (Universal Bottom Bracket) design which allows ROTOR to use the same power meter with both their road and MTB cranks. 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 1.2 is powered by a AA battery and records your power readings via your ANT+ head unit.
