Pro-level power management taken to a new level: Since our introduction of the world’s first-ever wireless power meter in 2006, we’ve been continually striving to improve it. The PowerTap G3C and G3 hubs raise the bar to another level altogether: lighter, stiffer, ANT+ compatible and better than ever.
The G3 also uses super high quality, ceramic bearings to ensure you'll be rolling along with the least amount of resistance and at the lightest weight.
At PowerTap, we realize that data can be the difference between first and second, and PowerTap is the precise instrument that gives you access to real-time performance measurement, accurate to within +/- 1.5%. PowerTap hubs are the perfect tool to improve power and performance to ensure you have your best season ever.
