THE STAGES DIFFERENCE

Stages Power meters are precision instruments assembled by hand at our Boulder, Colorado facility to exacting standards. To us this isn’t just the best way to make a power meter, it’s the only way.


With five Tour de France overall wins along with the Giro d’Italia, Vuelta a Espana and countless other victories in all other cycling disciplines, no other power meter is as tested—or as trusted—as Stages.

FAQS

  • What is a power meter?

    A power meter is a device on a bicycle used to measure the power output of the rider. Stages Power meters are all crank-based and use strain gauges to measure the torque, or flex, in the crank arm. The torque data collected as well as cadence are used to calculate power, as displayed in watts, and used to determine the riders’ effort.

  • What data will a power meter give me?

    Stages Power meters collect power data, displayed in watts and have an integrated accelerometer for magnet-free cadence. When paired with your favorite app or head unit, you’ll be able to view ride time, distance, elevation profiles, power, cadence, and more, depending on the device.

  • What do watts mean?

    Watts are the unit that the power is displayed in. Simply put, power displayed in watts tells how hard you’re working on the bike, and is the most accurate way to capture your true effort. Unlike heart rate, power is not affected by lack of sleep, dehydration, heat, stress or caffeine, and while heart rate changes can lag behind short efforts, power data is instantaneous. Power is the perfect tool to understand how you are progressing and the best indicator of fitness gained and fatigue level.

  • How do power meters work?

    To measure torque, Stages’ proprietary strain gauges are laid precisely along the crank arm. These gauges can detect the smallest flex in the stiffest crank and every pedal stroke causes a small amount of flex along the crank arm. This downward force happens in every rotation. Using an accelerometer, the Stages meter measures cadence. Once cadence and torque are collected, they are multiplied together to determine the power of a single pedal stroke. Stages Power meters are equipped with Active Temperature Compensation firmware, which automatically adjusts for temperature changes during your ride, so you can trust your data. Stages meters offer both ANT+ and Bluetooth transmission protocols to simplify the setup process and ensure that power meters are compatible with a broad range of other devices, including smart trainers, phones, cyclometers and more. Read more about the science of Stages here.

  • What is a single sided power meter?

    A single sided power meter goes on either the left or right side of your bike and measures power just on the one side. There have been 5 Tour de France wins with Stages left sided power meters. Right sided power meters are great for tight clearance gravel, mountain and aero bikes.

  • What is a dual sided power meter?

    A dual sided power meter means you have power meters on both the left and right sides of your bike. With a dual sided power meter, you’ll be able to view advanced data such as your true left/right balance, torque efficiency and pedaling smoothness.

  • How do I know what power value should be my target?

    We recommend performing a threshold test, which can be accomplished with help from the Stages Cycling app, and will help guide your power training. Having an accurate threshold value will assure that training zones and other metrics are calculated correctly. Functional Threshold Power (FTP) is the maximum wattage you can sustain for a long duration, usually 1 hour. This number is the basis for setting your power training zones and calculating several power based metrics, such as TSS, T-Score, and IF.

  • How do I pair the Stages Power meter with my GPS cycling computer?

    Activate your power meter by rotating the sensor. From the main menu on your Stages Dash, select ‘Activity Sensors’ and ‘Add Sensor’, and you should see your sensor populate to confirm. Detailed steps can be found here.

  • What side of the bike does a power meter go on?

    The most common Stages Power meters will go on the left side of your bike, but Stages sells power meters for both sides. You can buy a left sided power meter, right sided, or dual sided Stages Power meter.

  • Do I need a power meter even if I'm not a pro cyclist?

    Power meters are a fantastic tool for riders of all strengths and disciplines. Power meters are the single best tool to increase cycling performance, whether you’re training to win a world championship or training for your first race. You’ll get the data you need to be successful, ride smart and ride safe. A power meter will help any cyclist accomplish a goal with the ability to see and measure progress.

  • Can I add a power meter to any bike?

    To ensure your bike is compatible with a Stages Power meter, we recommend checking these primary compatibility guidelines for your bike: frame clearance, chain stay brake, crank compatibility. Read more here.

  • Does the Stages Power meter pair to a non-Stages cycling computer?

    Yes! Pairing via ANT+: Follow your head unit manufacturer's instructions to add the power meter, identifying it on the list of devices by the left side power meter's ANT+ ID (printed on the sticker below the power meter pod). Pairing via Bluetooth: Follow your head unit manufacturer's instructions to add the power meter, when viewing a list of devices, identify the left power meter based on the sensor name, which should include the left power meter's ANT+ ID (i.e. Stages 12345).

  • Accurate Power Meter for Cyclists & Triathletes

    Know how hard you are training, know when you push harder and when to pull back for maximum workout efficiency. See your average power and 3 second power easily while riding to make adjustments during your ride.

  • Cost of A Power Meter

    Stages Power meters range from $199 to $899 depending on the model. The cheaper options for new power meters are generally left sided and more expensive are dual sided power meters. The cost of a power meter will be reduced if you choose Stages Factory Install Service (install on your own crank) instead of buying a new one.

  • Dual power vs single sided power meter for cycling

    Depending on the level of data you want you can choose either dual or single-sided power. Dual power will allow you to know which leg is working harder, and help you and your coach determine if you should do additional 1 leg exercises to improve your overall performance.  Single sided power will still provide actionable information, just not leg specific. Single-sided power will enable you to know your overall stats of the ride, the real-time energy output (ideally paired with a heart rate monitor) allowing you to look at each rides effort to ensure you are training correctly to reach maximum efficiency.
