Sram Red / Force AXS Carbon Quarq Powermeter Crankset, DUB, Sram Road 12x2/1-speed, 4-arm chainring mount, 107mm bolt circle, 8-bolt mounting
SRAM AXS Power Meter Spider
The Quarq power meter spider for Sram Red and Force AXS DUB cranksets with an asymmetrical 107 mm bolt pattern. Only compatible with Quarq power meter crank arms and Sram Red or Force DUB crank arms.
The newly developed Quarq power meter now features Bluetooth Low Energy (BLE) technology in addition to the ANT+ wireless standard, improved measurement technology in the spider, an optimised design and new Qalvin software. The asymmetrical 107 mm bolt pattern allows for a minimum chainring size of 34 teeth. The new version with a carbon spider is significantly lighter.
Quarq Red AXS Power Meter Crank Arm:
The SRAM Red AXS Quarq power meter DUB crankset is compatible with SRAM Red or Force DUB and Quarq DUB cranks. These feature the 8-bolt mounting for the crankset
Quarq technology:
This system operates independently of chainring sizes, as it measures only the force applied by the rider. The Quarq power measurement system is one of the lightest wireless power meters, featuring simple installation and straightforward battery replacement. Thanks to its compatibility with Bluetooth and ANT+ wireless technology, the crankset can be synchronised with a wide range of display devices. The Quarq DFour power meter, featuring 10 strain gauges, has an accuracy of ±1 per cent. The Quarq power meter incorporates Power Balance and OmniCal technologies. The integrated electronics minimise interference and signal overlap, reduce exposure to wind and weather, and guarantee unrivalled durability and reliability. The Quarq Power Meter performance measurement system consists of the CinQo-Saturn ring and the SRAM Red Exogram crankset. Here, the CinQo-Saturn, equipped with state-of-the-art measurement technology, replaces the standard 4-arm spider of the crankset. The patented measurement technology is integrated into the four arms. This is connected by the Ring of Saturn to enable even more accurate measurement of power data.
Quarq measurement technology:
The Quarq power meter measures power by combining torque, pedal force, angular velocity and cadence, using the strain gauge technology also employed in other power meters. The pedal force applied by the cyclist causes the entire crank to bend slightly for a brief moment. This slight deformation is transmitted to the strain gauges mounted in the crank arm, which can thus measure the deformation and determine the torque. The Quarq CinQo-Saturn uses 20 strain gauges on 10 strain gauge strips in an arrangement patented by Quarq. Data transmission -
Quarq Wireless:
Data transmission is carried out using Bluetooth and ANT+ Sport technology. This wireless data transmission technology is particularly energy-efficient and therefore perfectly suited for use in mobile devices. This makes the Quarq power meter compatible with many receiving devices, e.g. Garmin Edge, Cat Eye Stealth 50, O-Synce Marco X. Power supply: Unlike all other power meter systems, Quarq uses a standard CR2450 battery, which can be replaced by the user without tools. The battery cover is designed similarly to a contact lens case and keeps the battery securely and dry in place. The battery life is approximately 400 hours of continuous use.
