The PowerTap G3 hub was designed to optimize stiffness and weight. Hub flange spacing was increased from Gen 2 to improve lateral wheel stiffness, while weight was reduced by 90g to bring the G3 down to an impressive 330g.
Internal hub electronics were moved outboard and are housed safely within the Powercap to allow easier service and battery replacement.
The PowerTap G3 hub is sold without additional external electronic displays or accessories, which can be purchased separately to customize your system. The included PowerTap Dual ANT+ and BLE (Bluetooth) wirelessly transmits power data to ANT+ or BLE devices.
