SRAM AXS™ Power Meter Spider 1×12/2×12

SRAM’s AXS™ Power Meter Spider allows you to upgrade your compatible SRAM Road 12-speed crankset to a complete power meter with a flick of the wrist. The power measurement system by Quarq with DZero™ measurement technology is completely integrated into the spider’s design. The spider is fitted to the Direct Mount fitting of the crank arms. All you need to do is install the spider, fit the chainring or chainrings and get going!
With the X-Range™ technology, SRAM has managed to shift the gear range of the drivetrain from the front to the rear. When combining the AXS™ Power Meter Spider with a RED®1 or FORCE®1 12-speed crank, you get a lightweight, strong and intuitive singlespeed drivetrain that provides the perfect gear ratio for fast-paced cross-country rides or cycle races and tours in flat terrain, depending on the chainring size.
In combination with a FORCE® 2 x 12 crank, you get a versatile double speed system with a consistent chainring distance of 13 teeth. This makes for smoother and faster shifting and always delivers the right gear combination when used together with a 12-speed cassette.

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 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.
