Technologies

X-Range™
Road bikes have become faster and more versatile than ever over the years, and riders are expanding what is possible on a road bike. X-Range™ is an innovation for today's riders. Road gearing has been completely rethought to offer a wider, more progressive range while providing smarter shifting parameters. With X-Range™, you can be sure you have always chosen the best gear.

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

DUB™
Sram DUB™ bottom bracket and crankset technology is a tireless workhorse, looking to the future while remaining backwards compatible. It is designed for the most demanding professionals and those who want to fit it and forget it. DUB™ is compatible with the main bottom bracket standards and fits any frame without compromise. It also opens the door to a new type of spindle for the lightest crankset ever produced. A new approach that combines the best features of the existing GXP and BB30, offering exceptional bearing durability without sacrificing the stiffness of large-diameter spindles.

DUB-PWR
DUB-PWR takes Quarq's reliable, accurate power measurement and elegantly integrates it into the DUB crank spindle to make it compatible with any gearing configuration, measuring left-side power to calculate total watts. It is lightweight, invisible and accessible.
