ALWAYS IN THE RIGHT GEAR

Road bikes are faster and more capable than ever, and riders are expanding what’s possible with drop bar bikes. X-Range™ offers wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS™

QUIET, SECURE, AND SMOOTH

On tarmac or gravel, 1x or 2x, eTap AXS™ gives a quiet, secure, and smooth ride. Thanks to Orbit™ chain management and a unique Flattop™ chain, you’ll ride more confidently and efficiently than ever— no matter the terrain.

EASILY PERSONALIZED

Control. Personalize. Monitor. AXS™—SRAM’s new bike component integration system—takes eTap® wireless shifting to the next level. The SRAM AXS™ app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

TECHNOLOGIES

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.

Flattop™

To enable X-Range™ gearing technology, we developed a narrower chain. The unique link shape of Flattop™ technology not only allowed for a wider gear range, but also results in quieter drivetrain operation and increased chain strength and durability.

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.

XDR™

The XDR™ driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR™ interface is 1.85mm longer than XD™ and is designed for road hub applications. XDR™ driver bodies are compatible with all XD™ cassettes when the cassette is installed with a 1.85mm spacer.

Orbit™

Orbit™ technology is an innovative new form of derailleur motion control. It utilizes silicon fluid as part of an elegant and ultralightweight damper system. Compared to a standard friction clutch system, Orbit™technology places no additional resistance on the rear derailleur’s spring when under slow or light movement. This means easier shifting and rear wheel removal.
And while riding, the fluid damper reduces chain bounce. It’s rock-solid reliability for both 1x and 2x systems.
