About Rotor Power Meters

ROTOR Power Meters – Power Meter City


Rotor have been producing market-leading power meters for 25 years, keeping at the top of their game through learning, innovating and perfected engineering.

Cycling with a power meter teaches you how to ride stronger, more consistently and allows for tracking, planning and training with specific focus on your unique needs and goals.

There is a choice of three power meters, all of which are compatible with a range of components.

  1. Get started in training with watts with INpower
  2. Take your training to the next level with INspider
  3. Train like a pro with 2INpower Rotor power meter comparison chart

All three allow pedal stroke improvement and track your ride with real time data including the proprietary metrics:

  • TORQUE 360 and effectiveness
  • Optimum Chainring Angle (OCA), helps identify your Optimal Chainring Position (OCP). 
  • Pedal smoothness
  • Combine this key information with Q RINGS® oval chainrings to adjust your OCP.

Connect to your cycling device or smartphone via Bluetooth® Smart or ANT+ to get a complete picture of your pedalling performance with analysis platforms such as TrainingPeaks.com. Combined with the free ROTOR power smartphone app, access equivalent metrics and graphs that previously have only been available in biomechanical training labs.
