QUARQ 2x12-speed AXS Power Meter Kit for Red / Force

The QUARQ power meter kit for Red AXS 2x12-speed includes the chainrings and the integrated power meter. It is only compatible with newer Red and Force AXS cranks that have an 8-bolt direct mount. The SRAM Red AXS power meter convinces with its high accuracy and low weight. There is a difference of 13 teeth between the chainrings, which ensures precise shifting.

QUARQ Operating Principle
The crankset forms the heart of your bike. Their only task is to convert the force of both legs into forward motion - the perfect place to measure performance.
Power meters calculate power by measuring torque (pedal force) and angular velocity (cadence). Power = torque x cadence. When you pedal, all parts of the bicycle drivetrain shift (bend) slightly under the load. Power meters are designed using FE analysis so that these displacements take place in a very controlled manner and at specific locations in relation to the applied load. Strain gauges are used to measure this displacement and thus calculate the applied torque. Reed switches are used to calculate the cadence.

DZero
DZero is QUARQ's next generation power meter, named after the DZero Experiment, one of the most accurate and innovative scientific projects to discover subatomic particles. With a revised measurement loop, an optimised strain gauge design, increased accuracy and modern software, DZero represents the " state of the art" for power meter technology. You can choose between Bluetooth LE and ANT+ technology for data transfer.

AXS
AXS is SRAM's electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows you to view battery status, change component behaviour, adjust controls, receive maintenance reminders and update firmware.
