Building on the success of the original eTap wireless components, the updated and enhanced SRAM Red eTap AXS 12 Speed Rear Derailleur is ideal for modern road and gravel bikes. In addition to its 12 gear range, it's ready for 10-33 tooth cassettes. The SRAM Red eTap AXS rear derailleur means exploring new limits has never been easier. It features a high-quality carbon cage material for fantastic strength and durability, without adding any unnecessary weight to your bike. Thanks to its AXS wireless technology, it offers easy personalisation, while its advanced chain management keeps it silent and secure no matter the terrain. Another highlight is it comes with faster pulleys, bearings, motors and signals to improve speed in every way and ensure you're always in the right gear.


AXS Enabled Rear Derailleur
Control. Personalize. Monitor. AXS is SRAM_x0092_s bike component integration system that takes eTap wireless shifting to the next level. The SRAM AXS app allows riders to see battery status, change component behaviour, personalise controls, get maintenance reminders and update the firmware.

Super Smooth Orbit Technology
On tarmac or gravel, 1x or 2x, eTap AXS gives a quiet, secure, and smooth ride. Thanks to the ultra-lightweight Orbit fluid damper, you_x0092_ll ride more confidently and efficiently than ever, no matter the terrain.

X-Range Modern Gearing
Road bikes are faster and more capable than ever before, and riders are expanding what_x0092_s possible with drop bar bikes. X-Range offers wider range, more useful and smoother gear progression, as well as smarter shift settings, enabled by AXS.

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 technology in SRAM's 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. The right lever makes it harder, the left lever makes it easier and 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_x0092_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_x0092_s rock-solid reliability for both 1x and 2x systems.

AXS: AXS is SRAM_x0092_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 behaviour, 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_x0092_s possible with drop bar bikes. X-Range is gearing for today_x0092_s road riding. We completely reimagined road gearing for a wider range, more useful and smoother gear progression, as well as smarter shift settings_x0097_enabled by AXS. With X-Range, you_x0092_re always in the right gear.
