Technology

X-Range™
Over the years, racing bikes have become faster and more versatile than ever before, and cyclists are expanding the range of possibilities with a road bike. X-Range™ is an innovation for today's cyclists. Developments for road bikes have been completely rethought to offer a wider and more progressive range, while offering smarter gear shifting parameters. With X-Range™, you can be sure of always choosing the best gear.

AXS™
AXS™ is the new Sram component integration system that connects the bike's electronic components to the application. The Sram AXS™ App allows cyclists to see the battery charge level, change the behaviour and customise the shifting controls, as well as receive maintenance reminders and download app updates.

DUB™
Sram DUB™ bottom bracket and crankset technology is a tireless workhorse, forward-looking yet backwards compatible. It is designed for the most demanding pros and for those who want to use it and forget it exists. DUB™ is compatible with the most important bottom bracket standards and mounts on any frame without having to compromise. In addition, it opens the door to a new type of axle for the lightest crankset ever produced. A new method that combines the best features of the existing GXP and BB30, offering exceptional bearing life without sacrificing the rigidity of thicker axles.

DUB-PWR
DUB-PWR takes Quarq’s reliable and accurate power measurement and elegantly houses it inside the DUB crank spindle for compatibility with any chainring setup, measuring left side power to calculate total watts. It’s lightweight, invisible and attainable.
