Sram Force AXS Power Meter, FC-FRC-1P-E1

Measure your ride and performance data with the Force 1 AXS power metre more precisely than ever before. It is the lightest and stiffest power metre we have developed to date. It is accurate to within +/- 1.5%, is unaffected by temperature fluctuations and, with the Direct-Mount X-SYNC chainring, is aerodynamic and even more durable. The lightest, stiffest and most accurate combination of power meter and chainring is now available in the Sram Force AXS power meters. The new power meter with the Direct Mount chainring mount enables the most precise measurements, guaranteeing the highest accuracy in power measurement. Quarq technology is accurate to within +/-1.5 per cent and is not affected by temperature fluctuations. The integrated chainrings are not only unbeatable in performance but also incredibly durable.

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 found 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 -

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 X-Sync chainring technology:

The X-Sync technology chainring, featuring wide and narrow teeth, offers maximum chain control. SRAM’s engineers analysed the performance and wear of thousands of previous chainrings to achieve this. The aim was to create a chainring that enhances performance under all riding conditions. The result: the chainring teeth are longer and shaped like a saw blade to grip the chain perfectly. The chainring thus increases chain tension and pedalling efficiency. At the same time, friction, chain noise and wear are reduced.

SRAM DUB crank axles 28.99 mm:

SRAM has developed its own axle standard for DUB cranks. SRAM DUB cranks have an axle diameter of 28.99 mm and are only compatible with bottom brackets designed for DUB cranks. The DUB road bike cranks have a chainline of 106 mm and are only compatible with DUB road bike bottom brackets

DUB Road Chainline:

SRAM offers DUB road and gravel crankarms in DUB Road and DUB Road Wide versions.

• The DUB Road cranks have a chainline of 45 mm and an axle length of 106 mm
• The DUB Road Wide cranks have a chainline of 47.5 mm and a spindle length of 112 mm
