Technologies

X-Range™
Over the years, racing bikes have become faster and more versatile than ever, 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 more intelligent gear shifting parameters. With X-Range™, you will be sure that you have always chosen the best ratio.

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

DUB™
Sram DUB™ technology for bottom bracket and crankset is a tireless workhorse, projected towards the future but at the same time 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 can be mounted on any frame without having to make compromises. Plus, it opens the door to a new type of axle for the lightest crankset ever made. A new method that brings together the best characteristics of the existing GXP and BB30, offering exceptional bearing life without sacrificing the rigidity of the thick pins.

DUB-PWR
DUB-PWR takes Quarq's reliable and precise power measurement and elegantly places it inside the DUB crank spindle to make it compatible with any chainring configuration, measuring left-side power to calculate total watts. It is light, invisible and reachable.
