SRAM Red AXS 48/35 chainrings with potentiometer

SRAM Red AXS 48/35 chainrings with Power Meter Quarq

With the SRAM RED® AXS™ Power Meter Kit, you quickly equip your compatible SRAM 12-speed road crankset with an effective power meter. The powerful Quarq power meter with DZero™ technology is fully integrated into the one-piece Direct Mount chainring with X-Range™ technology. This is why its assembly is carried out just as the assembly of the trays. Screw on it, and go!

With X-Range™ technology, SRAM manages to shift gears from front to rear. Then, the chainrings of all RED® double chainring cranksets and power meters are smaller in a consistent 13-tooth ratio, which leads to smoother, faster shifting and, together with the 12-speed cassette, always engages the right gear.

Your pedaled power in watts is calculated by multiplying torque (pedaling force) by cadence (repetition of measured movements). High quality sensors capture power data with an accuracy of +/- 1.5%. And thanks to the Power Balance™ technology independently of the right and left leg. In addition, the DZero™ power measurement technology also takes into account weather parameters such as temperature. This prevents cold or heat from influencing the measurements.
The SRAM RED® AXS™ power meter transfers captured data wirelessly either via ANT+ radio protocol or Bluetooth 4.0 (BLE). It is then compatible with the majority of smartphones and most common cycle computers that can display power data. On the SRAM AXS™ app, you perform setup, calibration and integration into an AXS™ road bike shifting groupset. On the SRAM AXS™ app, you view battery status, set up keys and components, manage revision reminders, and update firmware.
