Details

The SRAM RED® AXS™ power meter not only breaks with “long-serving” traditions, but it also brings a new level of performance. Based on the RED® 12-speed crankset with its elegant Exogram™ carbon crank arms, the powerful measurement system completely integrates the DZero™ power measurement technique into the one-piece DirectMount chainring design with X-Range™ technology. With this technology, SRAM has managed to shift the gear range of the drivetrain from the front to the rear. Thus, all RED® double cranks, including all power meters, feature smaller chainrings and a constant chainring spacing of 13 teeth, which results in smoother and faster shifting and always provides the perfect gear ratio in combination with the 12-speed cassette at the rear.

The power output in watts is calculated by multiplying torque (pedal force) by cadence. High-quality sensors determine performance data with +/- 1,5% accuracy. Moreover, they offer independent right and left leg measurement thanks to the Power Balance™ technology. What’s more, the DZero™ power measurement technology even takes into account climatic parameters like temperature. This eliminates fluctuations of the measured values caused by high or low temperatures.
The SRAM RED® AXS™ power meter transfers all data collected wirelessly, using ANT+ or Bluetooth 4.0 (BLE). Thus, it is compatible with most smartphones and almost all common bike computers that designed to display performance data.
Adjustments, calibration and integration into an existing AXS™ Road group are done via the SRAM AXS™ app. This electronic integration platform allows you to check the status of the battery, fine tune the components, adjust the controllers, receive maintenance reminders and update the firmware.

AXS™

AXS™ (pronounced “access”) is an electronic integration platform that connects electric bike components with software by SRAM.
AXS™ components communicate wirelessly using 128-bit encryption. Every time several components of a groupset are connected with each other, e.g. shifter, front derailleur and rear derailleur, a unique code is generated to eliminate the risk of interference with signals of other riders’ systems.
The SRAM AXS™ App allows you to check the status of the battery, change component behavior, customize controls, get maintenance reminders and update the firmware.
The app is available for free download in the App Store for iPhone (iOS) and in the Google Play Store for Android.
Note:
All SRAM RED® eTap 11-speed components are NOT compatible with AXS™ components and the AXS™ software!

X-Range™

Road bikes and road cyclists are faster and more capable than ever. The X-Range™ technology offers a wider and better range of gears. Thus it provides smoother, more useful gear progression. Smart shift settings (enabled by AXS™) transfer the simplicity of singlespeed systems to double speed drivetrains. Thus, you’ll always find the right gear. Faster – more efficient – more comfortable!

DUB™

The relationship between 28.99 mm diameter spindle and bottom bracket is the core of the DUB™ technology. This is where stiffness meets durability. Thanks to the system approach of integrating the relationship between chainring, crank, spindle and bottom bracket, SRAM has managed to make everything easier and better. It’s particularly the bottom brackets that benefit from increased durability thanks to an improved protection against dirt, resulting in enhanced drivetrain performance.

DZero™

Quarq’s power meter platform DZero™ is named after the DZero experiment. One of the most accurate and innovative projects of modern science to detect subatomic particles moving at the speed of light. With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances, DZero™ represents the state of the art in power meter technology.

Power Balance™

The Power Balance™ technology displays the ratio of power generated in the right drive stroke (first half) versus the left drive stroke (second half). This helps you find muscular imbalances and work on an equal pedal stroke over 360 degrees of rotation.

Why train with a power meter?

Ambitious and/or professional training control and analysis has its limitations when monitoring your heart rate only. While it may take up to 2 minutes to reach the heart rate zone that reflects your effort level, a power meter gives you direct feedback within seconds. Besides, a power meter is not influenced by external factors like weather, fatigue or health problems. Therefore, the measured values are extremely precise and comparable. This especially proves advantageous for short and intensive training sessions. When using a model that offers independent power measurement for the left and right leg, you’ll additionally have the great advantage to analyse the difference between right and left leg power, find imbalances and work on them. Thus, you can reduce muscle power deficits and improve your riding and pedalling technique.
