SRAM Force eTap AXS Rear Derailleur 12-speed Medium Cage

Fast, precise rear shifting is now more attainable than ever. Whether you ride 2x or 1x, tarmac or gravel, the SRAM Force eTap AXS™ rear derailleur is up for the task. It features Orbit™ damper technology for quiet, secure chain management over rough roads and capitalizes on larger X-SYNC™ pulleys for improved durability and efficiency.

AXS
AXS is SRAM's new electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows riders to view battery status, change component behavior, adjust controls, receive maintenance reminders and firmware updates.

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.

X-Range
Racing bikes are faster and more powerful than ever before and riders keep showing what bikes with racing handlebars are capable of. X-Range offers a wider range of gear ratios, as well as an even more pleasant and usable gear gradation... and also has smart, programmable shift settings thanks to AXS.

Orbit
Orbit technology is an innovative new form of rear derailleur motion control. It uses silicone fluid as part of an elegant and ultra-light damping system. Compared to a conventional friction clutch system, Orbit technology produces no additional resistance to the rear derailleur spring during slow or light movement. This means easier shifting and rear wheel removal. During the ride, the fluid damper holds the chain back in a refined and elegant way. With maximum reliability and chain tension, for 2-fold and 1-fold systems.
