If your ride doesn’t feel complete until you get a little dirt on your tires, you know the importance of capable components that can tackle anything. The RED XPLR eTap AXS rear derailleur is a dedicated 1x-specific unit designed for use with the XPLR 10-44 cassette. It makes for an uncluttered drivetrain that takes on pavement and singletrack with equal aplomb. Wireless and proven eTap shift logic, AXS connectivity and advanced chain management mean this derailleur does exactly what you want when you need it.

Technology

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 deliver optimal performance in muddy conditions, the X-SYNC chainrings feature 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 the new SRAM RED eTap groupset, such as wireless shifting, advanced battery power management, and mechatronics technologies, is 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; both levers hit the front derailleur. Simple, unmistakable, and intuitive.

Orbit

Obit technology is an innovative new form of derailleur motion control. It utilizes silicon fluid, a part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch, Orbit technology places no additional resistance on the rear derailleurs' 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.
