The SRAM RED AXS E1 Rear Derailleur sits at the core of SRAM’s premier electronic drivetrain ecosystem, delivering exceptional shifting speed, refined efficiency, and unrivalled versatility. Lighter and more capable than the previous generation, this rear derailleur is designed to meet the demands of elite road racing, endurance riding, and fast everyday road cycling.

Widely installed by Brisbane bike shops, the RED AXS E1 rear derailleur is a preferred choice for professional bike fitting, high‑end road bike builds, and expert bicycle servicing across Queensland.

One Rear Derailleur for 1x and 2x Road Drivetrains

The RED AXS E1 rear derailleur is engineered to handle both 1x and 2x road configurations, covering a broad cassette range from 10–28T through to 10–36T. This flexibility allows riders to fine‑tune gearing for flat racing, rolling terrain, or steep climbs without changing derailleur models.

This wide compatibility makes the RED AXS E1 well suited to modern road bikes built for versatility and performance.

Improved Efficiency with Larger X‑SYNC Pulleys

SRAM has equipped the E1 rear derailleur with larger X‑SYNC pulley wheels, reducing friction and improving drivetrain efficiency. The result is smoother power transfer, quieter operation, and improved energy conservation during long rides and sustained high‑output efforts.

Combined with refined cage shaping, these pulleys contribute to a noticeably more fluid ride feel.

Orbit Chain Management for Control on Rough Roads

Integrated Orbit fluid damper technology keeps chain movement controlled and secure, even when riding over rough tarmac, broken backroads, or high‑speed descents. This system reduces noise, limits chain slap, and maintains shift precision without compromising drivetrain efficiency.

It’s an ideal feature for Queensland roads where surface quality can vary significantly.

Lighter E1 Construction with Proven Durability

The RED AXS E1 rear derailleur is approximately 16 grams lighter than the previous generation, contributing to overall bike weight reduction while maintaining stiffness and durability. Every refinement is aimed at improving performance without sacrificing reliability for daily training or race use.

Seamless Wireless SRAM AXS Integration

As part of the SRAM AXS platform, the RED AXS E1 rear derailleur offers simple wireless setup, easy pairing, and ongoing customisation through the AXS app. Riders can configure shift behaviour, monitor battery status, and update firmware without cables or mechanical adjustments.

The derailleur is compatible with existing SRAM AXS batteries, allowing easy swaps between components.
