The Stages Cycling G3 Power L Shimano Ultegra R8000 Power Meter will provide you with the means to focus your training and achieve your targets.

This left-side crank can be added to your existing Ultegra crankset and offers market-leading accuracy of ± 1.5% so you can be sure of realistic data readings. Active Temperature Compensation makes sure that you obtain consistent readings, no matter the weather, and the 175-hour battery life means you won't have to worry about replacement for quite some time.

Stages Cycling G3 Power L Shimano Ultegra R8000 Power Meter

Enhance your training and get the results you're after by adding the Stages Cycling G3 Power L Shimano Ultegra R8000 Power Meter to your setup. A number of upgrades from the 2nd generation offerings mean improved accuracy and faster radio, Bluetooth and ANT+ transmission and an LED indicator displaying basic information such as battery quality.

Reading the power from your left leg, the market-leading accuracy means that all your readings will be within ± 1.5% of your actual power, for a true representation. Drops and rises in temperature won't affect this accuracy, so you'll get consistent readings no matter the conditions. You can train with power even in the pouring rain, thanks to the IPX7 water resistance rating, improving this units durability, functionality and versatility.

Even the most powerful riders will be well catered for with the unit reading up to 2500 watts, and cadences up to 220 rpm will be recorded. You can read your data in real-time on any compatible head unit, transferred via ANT+ or Bluetooth Smart. Six times improved signal strength means data is transmitted even faster to your head unit, so there'll be no delays.

The battery lasts around 175 hours and the LED indicator will keep you aware of when it's nearly time for replacement, which is a quick and easy, tool-free task. It's easy to keep your unit's software up-to-date with wireless firmware upgrades, and it can be synced to third party apps including Training Peaks and Strava.

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 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.
