The Stages SC series bikes equipped with a Stages Power meter read the rider's actual power through a sensor attached to the crank arm. Unlike other bikes that include estimated or calculated values, we rely on a direct sensor to measure the rider's pedaling force (for accuracy up to +/- 2.5%). 


From this sensor, we broadcast power and cadence to be collected by the Stages SIC1 console or your own personal device (via Bluetooth or ANT+ wireless technology) so you can accurately record your workout and track your progress.
