Technologies

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. Sram 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.

AXS™

AXS™ is Sram’s new electronic integration platform 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.

X-Sync

Sram X-Sync™ 1x chain rings provide the highest level of performance and durability. The Sram X-Sync™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync™ rings are an integral part of the Sram 1x™ drivetrain.

eTap

All of the underlying tech in the new SRAM RED eTap groupset, such as wireless shifting, advanced battery power management, and mechatronics technologies, are meant to serve one ultimate purpose: to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive.
