SRAM RED® AXS™ Power Meter Crankset 2×12

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.
