Sram Red XPLR AXS E1 power meter crankset

The high-end DUB power metre for gravel use, with X Sync chainring compatible with 11-13-speed drivetrains

Tracking power progress on a gravel bike is now even easier and more accurate. With the new RED XPLR spider-based power metre and removable, bolt-on chainrings, the RED XPLR AXS power metre is lightweight, reliable in all weather conditions and accurate to within +/-1.5 per cent. With power measurement on both sides, even ambitious gravel training goals are within reach.

SRAM Red XPLR AXS Power Meter, FC-RED-1WP-E1:

The SRAM Red AXS Carbon crankset for the new AXS E1 Gravel groupset, when paired with the new 13-speed cassette, offers a completely new gear range. The smaller chainrings and the cassette with its wider range provide a greater gear range than previous systems. The result is smoother and faster front shifting and more usable gears. Weighing just 540 grams, the cranks are also significantly lighter. The new configurations this enables improve cadence and efficiency and ensure crisp, clean and fast shifting.

SRAM Quarq Technology:

The Quarq Power Meter performance measurement system consists of the CinQo-Saturn ring and the SRAM Red AXS Exogram crankset. Here, the CinQo-Saturn, equipped with state-of-the-art measurement technology, replaces the standard spider of the crankset. The patented measurement technology is integrated into the spider. This is connected via 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 Thread Mount chainring mount:

With the new Thread Mount system, the chainrings are screwed onto the crankset spindle in the direction of travel. This allows for an extremely torsionally rigid and lightweight construction. Tool No. 00.6218.042.000 is required for removal.

SRAM X-Sync:

SRAM’s X-Sync chainrings ensure maximum performance and durability. The long SRAM X-Sync tooth edges engage the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile, as well as the rounded, slanted edges, aid chain guidance. To deliver the best possible performance even on muddy terrain, the X-Sync chainrings feature recesses to clear dirt and mud away from the inner chain links and rollers. Manufactured in Germany, the X-Sync chainrings are a key component of SRAM’s single-chainring drivetrain

SRAM DUB Wide Axle Bottom Bracket System:

The DUB version of the SRAM cranks is suitable for BSA threaded, PressFit BB92, PressFit 30, BB30, BB386 Evo BB Right and T47 bottom bracket shells. You can find the matching bottom brackets below, along with the installation dimensions. The axles have a diameter of 29 mm. Axle play is adjustable via a preloader. The SRAM DUB road bike cranksets have their own proprietary standard and are only compatible with DUB road bike bottom brackets, not with other bottom brackets. SRAM and Wheels Manufacturing offer compatible bottom brackets for almost every bottom bracket standard; only bottom brackets for Italian thread and Trek BB90 are not available. In those cases, GXP crankarms are required.
