SRAM Eagle S500 AXS 12-Speed Rear Derailleur

The SRAM Eagle S500 AXS 12-Speed Rear Derailleur is a wireless rear derailleur that delivers precise 12-speed shifting, strong impact protection, and full AXS integration for consistent drivetrain performance. It uses AXS wireless technology to remove cables, giving a clean setup and accurate gear changes. Overload Clutch protection helps prevent damage by disengaging the motor during impacts and resetting instantly. A robust aluminium cage and Type 3 damper keep the chain stable and quiet across rough terrain.

Key Features and Benefits:

• Wireless AXS shifting system: This electronic shifting system removes the need for cables and housing, reducing friction and setup errors. It provides consistent shift accuracy with every input, resulting in reliable gear changes and less time spent on maintenance
• AXS ecosystem integration: The derailleur connects with other AXS components through a unified wireless system, allowing simple setup and easy customisation through the AXS app. This ensures your drivetrain works as a single system, giving better control and a more tailored setup
• Overload Clutch protection: This system detects impacts and temporarily disengages the motor gearbox to prevent internal damage. It then returns the derailleur to its original position, reducing the risk of failure and keeping your drivetrain working after knocks or crashes
• Type 3 cage damper: The damper controls cage movement to limit chain bounce on rough trails. This improves chain retention and reduces noise, leading to a quieter ride and fewer dropped chains in demanding conditions
• Aluminium cage construction: The cage uses strong aluminium to balance durability and weight. It resists bending under load while keeping the derailleur stable, which helps maintain accurate shifting over time
• Wide cassette compatibility: Designed to work with 10-50T and 10-52T Eagle cassettes, this derailleur supports a wide gear range for climbing and descending. This gives you flexibility across different terrain without compromising shift performance

Consistent and accurate shifting is critical when managing cadence and effort across varied terrain. The wireless system ensures each shift is delivered with the same precision, while the Overload Clutch and damper systems maintain stability under load. The result is a drivetrain that stays aligned, protected, and predictable through repeated use and harsh conditions.

This derailleur suits riders who want a clean setup, reliable shifting, and reduced maintenance. Its durable build and smart protection systems support long-term performance. It is a strong upgrade for any Eagle AXS drivetrain setup.
