QUARQ Red AXS DUB Power Meter Carbon Crankset

Welcome to the peak of power measurement: the Red AXS power meter crankset by QUARQ

The QUARQ Red AXS power meter crankset breaks with tradition and reaches a new level of performance. In a way, the road drivetrain was reinvented: with smaller chainrings and an extended gear range. All chainring sets come with a difference of 13 teeth, which guarantees precise shifting for every setup. This Red AXS crank also features fully integrated, original QUARQ power measurement technology.

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.
