Stages Dura-Ace R9100 L/R Gen 3 Double-sided Power Meter

The Stages Dura-Ace R9100 L/R is the double-sided power meter, that has been thoroughly tested by Team Sky. Chris Froome won both the Tour de France and the Vuelta in 2017 with this power meter. This power meter fits perfectly in the Stages performance Ecosystem. Combined with the Stages Link software and the Stages Dash cycling computer, the Stages Dura-Ace R9100 L/R comes into its own to the fullest. In addition to the power, the double-sided power meter also measures the flexibility the pedal rotation and the torque to yield

Left and right are measured by separate sensors and can be used independently. This enables you to for example mount the right crank on one bike and the left crank on another. If you use both crank arms on one bike, you get a double-sided power meter. Thanks to Active Temp Compensation (ATC), a precision of +/-1,5% at 100 watts and 90 RPM is achieved. The Stages Ultegra R9100 L/R is water resistant and has an IPX7 certificate. Both power meters have a CR2032 battery which lasts for about 175 hours.
