One rear derailleur to rule them all. The SRAM Force eTap AXS rear derailleur is designed for both 1x and 2x systems.

It capitalises on X-Range gearing technology for enhanced range and chain management and features larger pulleys for improved durability and efficiency. Strong, smooth, quiet and AXS enabled.

Technologies

X-Sync - SRAM X-Sync 1x chainrings 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 chainrings 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. Accept no imitation.

ETap - All of the underlying tech in their 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.

Orbit - Orbit technology is an innovative new form of derailleur motion control. It utilizes silicon fluid as part of an elegant and ultra-lightweight 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.

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, personalise controls, get maintenance reminders, and update firmware.  

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. We 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.
