SRAM Force® AXS™ Power Meter Crankset 2 x 12-Speed

Based on the Force® 12-speed crankset with its elegant carbon crank arms, the powerful Force® AXS™ measurement system completely integrates the DZero™ power measurement technique by Quarq into the one-piece Direct Mount 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 Force® AXS™ double cranksets, 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.
