Power measurement accuracy of <2.5% ensures consistent data for training analysis. Spin-down calibration keeps readings precise, while the direct-drive design eliminates tyre slip and reduces noise.
Smart Connectivity
ANT+ FE-C and Bluetooth Smart allow control from smartphones, tablets, sports watches and bike computers. You can ride stand-alone or connect to training platforms for structured workouts, virtual routes and performance tracking.
Wide Compatibility
The Flux 2 fits road, triathlon and MTB frames with 130/135 mm quick-release or 142/148 mm thru-axle spacing. It supports Shimano/SRAM 8-11 speed cassettes, with adapters available for other standards.
