2025 Sram X0 Eagle AXS Transmission Power Meter Crankset

X0 Eagle AXS Transmission Power Meter Crankset provides riders with accurate, live power data delivery housed in our most advanced aluminum crankset. The power meter technology is integrated through what we call "DUB-PWR" - a unique design that elegantly houses Quarq's reliable and accurate power measurement inside the DUB crank spindle itself. Measuring left-side power to calculate total watts, it's subtle, lightweight, compatible with any chainring setup, and boasts unbeatable battery life. It is also compatible with the Flight Attendant system, allowing for total connectivity between all AXS enabled components. No-compromise, no-fuss data delivery with robustness in mind.

Technical Features

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler-better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.

DZero

Quarq's next-generation DZero power meter platform is named for the D0 Experiment, one of science's most accurate and innovative projects to detect subatomic particles moving at the speed of light.

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bar bikes. X-Range is gearing for today's road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings-enabled by AXS. With X-Range, you're always in the right gear.

AXS

AXS is SRAM's new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.
