Description
The Stages Cycling G3 Shimano Ultegra R8000 R Right Side Power Meter Crank Arm can be used on its own or can be used to transform your single-sided left arm unit and measure the power from both legs.
With a ± 1.5% accuracy, you can be sure that readings are a true representation of your power outputs, and Active Temperature Compensation eliminates any potential anomalies when the external temperature rises and drops dramatically. The low profile design adds only a few grams to the weight of an Ultegra crank arm and has an IPX7 water-resistant casing to prevent ingress of rain, enhancing durability and reliability of the unit.
No matter how much power you put through the pedals, you will get accurate readings up to 2500 watts and you can perform high cadence intervals with measurable results up to 220 rpm. With a long 175-hour battery life, you won't need to replace the coin cell for quite some time, and when the time comes, this can be done easily using a Phillips screwdriver (not included).
The data from both crank arms will be transferred in real-time to your head unit via ANT+ or Bluetooth and can be synced to third-party training platforms, including Strava, Training Peaks and Stages Link, for further analysis post-ride.
To help find your current crank model, check the inside of the crank arm for the model and length. The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm Allen key wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
Still unsure? See this illustration for a guide of where to measure.
