Sram XX1 Eagle Quarq Boost Power Meter Crank
The newly developed Sram Quarq XX1 Eagle power meter now features the DUB axle system, compatible with all bottom bracket shells. Equipped with Bluetooth Low Energy (BLE) technology in addition to the ANT+ wireless standard, improved measurement technology in the spider, an optimised design and new Quarq software. Thanks to the carbon spider, the XX1 Eagle Quarq crankset weighs just approx. 626 grams without chainrings.
The SRAM XX1 Eagle Quarq power meter crankset features hollow carbon crankarms, Bluetooth and ANT+ wireless technology, an LED indicator light and tool-free battery replacement.
SRAM Quarq XX1 Eagle Power Meter:
The SRAM XX1 Eagle Quarq power meter crankset is compatible with all SRAM 12-speed MTB groupsets. 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 XX1 Eagle Powermeter, featuring 10 strain gauges, has an accuracy of ±1 per cent. The SRAM Red DZERO power meter features SRAM’s Power Balance, OmniCal, Magic Zero and AxCad technologies. The integrated electronics minimise interference and signal overlap, reduce exposure to wind and weather, and guarantee unrivalled durability and reliability.
Compatible chainrings:
The SRAM Quarq XX1 powermeters have a 104-tooth bolt pattern and are compatible with all 104-tooth chainrings. A list of the original SRAM X Sync 2 chainrings can be found below.
SRAM Quarq technology:
The Quarq Power Meter system consists of the CinQo-Saturn ring and the SRAM XX1 Eagle crankset. 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 five arms. These are connected by the Ring of Saturn to enable even more accurate measurement of power data.
Sram 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 measure the deformation and determine the torque. The Quarq CinQo-Saturn uses 20 strain gauges on 10 strain gauge grids in an arrangement patented by Quarq. Data transmission -
Sram 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.
Sram DUB Axle Bottom Bracket System:
The DUB version of the SRAM cranks is suitable for BSA threaded, PressFit BB92, PressFit 30 and BB30 bottom bracket shells. You will find the compatible bottom brackets further down in the text. The axles have a diameter of 29 mm and a length of 113 mm. The axle play is adjustable via a preloader. The SRAM DUB crankset has its own proprietary standard and is only compatible with DUB bottom brackets, not with other standards or bottom brackets.
