About the PowerTap G3 Track Hub

Specifically made for track cycling, the PowerTap G3 Track Hub delivers accurate, consistent and dependable power data lap after lap. Featuring +/- 1.5% accuracy and Bluetooth SMART technology, the hub has wider flanges for a stiffer overall wheel while maintaining its small overall hub profile. In addition, like all G3 hubs, the G3 Track Hub transmits both speed and cadence data, making it a go-to power meter for track cyclists.

Please note, matching PowerTap splined cogs sold separately (14t, 15t and 16t options available)
