Power meter kit / Quarq Sram Red AXS E1 | PM-AXS-KITR-E1

The Quarq power meter crankset for Sram Red and Force AXS DUB cranks with permanently mounted Red AXS chainrings. Only compatible with Quarq DUB and Sram Red or Force DUB crankarms. The chainrings are extremely durable and cannot be removed.

This is the ultimate integrated power measurement solution. The RED AXS Power Meter Kit combines the one-piece SRAM Red chainrings with Quarq technology to create the lightest, stiffest and most accurate power package on the market. A 13-tooth difference across all chainring sets ensures precise shifting in every setup and less dramatic changes in cadence when shifting at the front. Combined with the most durable SRAM chainrings, this is an unbeatable combination.

Ideal for perfectly tailoring the power measurement system to your needs.

Quarq Red AXS Power Meter Crank Set:

The Sram Red AXS Quarq power metre DUB crankset spider is compatible with Sram Red or Force DUB and Quarq DUB cranksets. These feature the 8-bolt mounting for the crankset spider. The chainrings and the power metre form a single unit. This ensures maximum torsional stiffness and power transfer.

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, offering easy 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 DFour 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 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. These are 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 the need for 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.
