SRAM S500 Eagle AXS 12-Speed Rear Derailleur Max 52T Without Battery

SRAM S500 Eagle AXS Rear Derailleur Without Battery is a rear derailleur model that offers wireless electronic shifting within SRAM’s Eagle AXS ecosystem at a more accessible and powerful level. Compatible with 12-speed Eagle drivetrains, featuring a maximum 52T cassette capacity, and offering customizable use via the AXS platform, it is a modern upgrade option for MTB, e-MTB, and gravel setups.

The S500 Eagle AXS rear derailleur was developed to work with the SRAM Eagle drivetrain ecosystem. Its compatibility with 10-50T and 10-52T Eagle cassettes provides light gearing for steep climbs and high efficiency on fast sections. Product descriptions state that the S500 Eagle AXS can be used with 10-50 and 10-52 cassettes, is compatible with AXS controllers, and works with the 12-speed Eagle system.

The AXS wireless platform makes installation, customization, and system management more convenient. On SRAM’s S500 Eagle AXS Upgrade Kit page, it is stated that this system was developed to upgrade Eagle drivetrains to AXS technology with the S500 AXS rear derailleur, AXS Pod Controller, AXS battery, and charger.

The Type 3 cage damper design helps increase chain tension and silence during descents. The Overload Clutch technology aims to reduce the risk of damage to the rear derailleur by protecting the motor/transmission mechanism during impacts.

This product is delivered without a battery. A SRAM AXS battery is also required for use. If you have an existing SRAM AXS battery, it can be used with this rear derailleur.

Featured in the Ultraviole SRAM collection, this product is a powerful option for users who want to upgrade their existing 12-speed Eagle system to a wireless electronic AXS setup or create a cleaner, more modern shifting system on an MTB or gravel bike.
