SRAM RED ETap AXS D1 12-Speed Rear Derailleur

The heart of the connected cadre. The SRAM RED eTap AXS™ rear derailleur is AXS enabled for easy personalization and
designed for both 1x and 2x systems. Advanced chain management keeps it silent and secure no matter the terrain. The
derailleur also comes with faster pulleys, bearings, motors and signals, improving speed in every way.

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 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 our 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, personalize 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.
