The PowerTap G3 Hub is the CPT Cycling recommended power meter if you want very robust and reliable power measurement, with total power, at a price under that of many single sided power meters. While this product may take a little extra time to set up to build onto your favourite set of hoops, once built into a wheel, can be easily transfered between similar bikes.

  • Power measurement taken inside rear hub
  • For quick release axle (can be converted to thru axle)
  • 11 speed freehub compatible
  • Bluetooth and ANT+ transmission
  • Compatible with CR2032 coin cell batteries
  • Power meter accuracy to + or - 1.5% (drivetrain power loss not significant)
