With pro-proven performance in the Tour de France, as well as in numerous World and National championships, Stages Cycling power meters will enable you to monitor and adapt your training to best suit your goals. Complete with 52/36 chainrings, the Stages Cycling Dura Ace R9100 Dual Sided Power Meter offers up Shimano's top-of-the-line crankset for the smoothest shifting, enhanced durability and strength and exceptional stiffness so all you power gets translated into speed. The 52/36 mid-compact chainrings ensure a wide gearing range so you can both spin up mountains and smash the descents.
When training with power, accuracy and reliability are equally important and with industry-leading ± 1% accuracy you can be sure of the data, and Active Temperature Compensation means that even with temperature changes, data will be reliable and free from anomalies. IPX7 water resistance ensures your unit will remain unaffected by the elements.
With both ANT+ and Bluetooth Smart connectivity, your numbers can be transferred to most head units, instantaneously, so it's easy to follow a training plan or just monitor your power stats. Registering power up to 2500 watts, even the strongest sprinters are well catered for, and cadences of 20 - 220 rpm will be displayed.
An LED indicator will display the battery level at start up, and the coin cells last over 175 hours. The latest software is easily available via wireless firmware upgrades, and the unit is easy to sync with a number of third-party apps including Training Peaks, Strava and Stages Link.

Is my bike compatible with Stages Power Meters?
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 wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
