QUARQ AXS DUB power meter carbon cranks - spider for SRAM Red and Force

The QUARQ AXS DUB power meter carbon cranks for SRAM Red and SRAM Force come with hollow moulded carbon crank arms, DUB axle and a power meter spider suitable for X-Sync Road and Force 12-speed chainrings. SRAM AXS riders benefit directly from the QUARQ power measurement technology, which has been tried and tested for years and scores with such practical features as temperature compensation, automatic calibration and integrated cadence sensors. The power meter is powered by a CR2032 battery that lasts around 200 hours. Of course it is compatible with ANT+ and Bluetooth.

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 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, optimised strain gauge design, increased accuracy and the features of the Qualvin and SRAM AXS app, DZero represents the state of the art in power meter technology. You can choose between Bluetooth LE and ANT+ technology for data transfer.

Exogram™
The hollow carbon construction provides an optimal ratio of stiffness and weight.

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.
