Another interesting bit on the showroom floor at Interbike 2015 was the Dynovelo spindle-based power meter. It inserts within the hollow spindle of most cranks and measures torque at the spindle (rather than at the spider as on most crank-based power meters, or at the crank arm as on Stages). Due to this method, the Dynovelo only measures the left leg's power, since the right leg's force doesn't twist the spindle. Still, it's an intriguing product that makes for some interesting possibilities. For example, this power meter fits into the Campagnolo Bora aero crank. It transmits on ANT+ only, and communicates and charges via USB. Check out the gallery for images of this interesting little device.

  • Just a couple tiny parts install into the crank arm, and are user-installable and allow user calibration for slope and temperature.
  • The device communicates and charges via USB and connects to ANT+ Wireless devices.
  • The measurement device that detects spindle twist.
  • From this angle, it looks like a tiny Arc Reactor for a Tony Stark action figure.
