The most advanced power meters in the world

Nearly a decade of relentless development. High-resolution Gen 3 electronics with enhanced signal strength. Certified water resistant to IPX7 standards. Active Temperature Compensation. Magnet-free cadence. ANT+ and Bluetooth transmission. Universally compatible. This is the gold standard for power meters.

Not all power meters are created equal
Stages power meters are precision instruments assembled by hand in Boulder, Colorado facility to exacting standards. This is not just the best way to make a power meter, it’s the only way.

More models. More options. More features.
Looking to add Watts to your sprint? Or just want to pace yourself over that big climb? With a wide range of models, features and price points, there’s a Stages for everyone.

Tour Proven
Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world’s best product proving ground, then Stages Power is proven as the world’s best power meter.

Active Temperature Compensation
Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions.

Individual meter calibration for the most accurate results
Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters.

The new compatibility
While not widespread there are some key bicycle models that are not compatible with the non-drive crank arm based Stages Power meter because of interference with the power meter housing, for example Cervelo's P5 and many bikes with chainstay mounted brake calipers. Stages Power R offers increased compatibility with these models as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR (dual) meter systems.

Technologies

The science of Stages
Stages meters are refined. Smart. Downright miniature. Made from the same material as bulletproof glass. Simply put, Stages Power meters employ the most advanced technology in the power meter category, all while being accurate, reliable and the simplest to maintain and use.

Stages Gen 3 Electronics
Refined over the course of nearly a decade, the third generation power meter electronics have state-of-the art radio hardware for enhanced signal strength, which ensures your power data consistently and reliably reaches your computer (or GPS watch) as well as an LED status indicator that shows pairing and battery status at a glance.

Active Temperature Compensation
Measuring power is easy in a controlled environment, but in real-world riding, weather conditions change constantly. The strain gages used in a power meter—regardless of whether it’s crank based, spider based, pedal or hub based—are made of metallic elements which are affected by even slight changes in temperature which, if not factored, can lead to inaccurate ride data. For this reason, 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.

Water resistant
Like fluctuations in temperature, moisture is a reality in cycling – whether it’s caused by high heat and humidity or freezing cold rain. Stages power meters are designed to meet or exceed the IPX7 standard for water resistance and tested extensively in-house in Boulder, Colorado facility as well as over thousands of miles out on the roads and trails.

ANT+ AND Bluetooth works with everything
Stages was the first power meter brand to offer both ANT+ and Bluetooth transmission protocols. This simplifies the setup process and ensures that our power meters are compatible with a broad range of other devices, including smart trainers, phones, cyclometers and more. This also provides two-way communication for wireless firmware updates.

Torque
To measure Torque, Stages’ proprietary strain gages are laid precisely along the crank arm. These gages, which are the same tool used in aerospace, can detect the smallest flex in the stiffest crank. In this case, every pedal stroke, causes a small amount of flex along the crank arm. This downward force happens in every rotation. This force, multiplied by 9.8 m/s2 and the length of crank arm are used to determine the force applied to a pedal stroke, or torque.

Cadence
Using an accelerometer (the same technology used to tell your phone how to orient its screen), the Stages meter measures cadence. The proprietary circuitry houses this cadence tool, allowing the meter to eliminate the antiquated need of magnets, external sensors, cables and zip ties to measure cadence. This modern technology also allows the meter to capture multiple positions per revolution, resulting in a faster response and better overall data.

Wattage 101 – Power
Simply put, power is a measurement – typically displayed in Watts – of how hard you’re working on the bike, and 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. Simply put, if you want to know how you’re doing, check your power.
