Technical Features

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.

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.

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.
