While many Zwifters use their smart trainers to detect power, many others own power meters which they use outdoors and on Zwift.

TrainerRoad’s lastest podcast episode is a good one for those interested in learning how these magical power meters really work. Featuring Scott Cooper, Product Manager at 4iiii, the short podcast focuses on the following:

  • What is inside a power meter?
  • How are power meters calibrated in the factory?
  • The difference between zero offset and calibration
  • Why is it hard to install a power meter on carbon?
  • How does temperature affect the zero offset of a power meter?
  • The future of cycling power meters
