Professional Grade Dual-Side Power Data

Ready to accurately track your power output from each leg? Stages Power LR power meters are the best upgrade you can add to your bike for measuring your output wherever you like to ride. With reliable, finely tuned power tracking technology that captures the power output from each leg, true left/right balance, torque efficiency and increased pedaling smoothness and fantastic price point, the Stages Power LR power meters are perfectly suited for both pros and recreational riders.

175+ hours of battery life with easy-to-replace CR2032 button batteries means you can spend less time charging your power meters and more time smashing out watts. Want to have power metering on two of your bikes? Simply de-couple your Power LR and fit each unit to whichever frames you prefer.

Why Bother With a Power Meter?

If you're serious about your ride, you probably already have a heart rate monitor to determine how hard you're working. As great as heart rate is to measure your effort, it can be affected by factors such as sleep, dehydration, heat, stress or even caffeine intake, and heart rate changes can lag behind short efforts.

Unlike heart rate, a watt is a watt - purely reflecting the power in your pedals regardless of varying physical and environmental factors. A power meter can measure your true effort instantaneously and is the best indicator of fatigue levels and fitness gained, helping you tune your workouts to improve your cycling performance to the max.

Works With Your Setup

With a variety of crank arm models, you're sure to be able to find a Stages power meter that'll fit seamlessly into your setup. With each power meter able to pair via ANT+ and Bluetooth, you'll have compatibility with practically every computer, phone or smart trainer available. 

Next-Gen Tech

Built with high-resolution Gen 3 electronics, Stages power meters provide you with enhanced signal strength, consistent capture of power data and transfer, all with high accuracy readings of ±1.5%. Employing proprietary strain gauges, Stages power meters can detect even the slightest flex created by your pedal strokes to measure your torque. Accelerometers provide precise measurement of your cadence, which is then used with torque data to calculate your output in watts. This clever setup negates the need for extra sensors or magnets when measuring your output.

Tougher Stuff

The low profile and tough construction of Stages power meters make them more than capable of going where you take them, whether on the road or through tough trails. You won't have to worry about wet weather either with a casing rated at IPX7 water resistance. Active temperature compensation provides consistent data readings no matter where, when or how hard you're riding, so you can be sure your results accurately reflect your performance on the bike.

Disclaimer: This power meter may not be compatible with some bike frames with tighter clearances. If you are unsure, or would like to check compatibility with other crank arms, click here.
