S500 Eagle AXS Rear Derailleur - 12-Speed, 52t Max, (Battery Not Included), B1

SRAM S500 Eagle AXS Rear Derailleur brings wireless AXS shifting to the Eagle 12-speed drivetrain with the crisp control riders want on modern trail and enduro builds. Designed around Eagle’s wide-range cassettes, it delivers confident shifts under real riding loads while keeping the drivetrain quieter and more stable on rough descents. Note: battery not included (sold separately).

Wireless shifting advantages that matter on the trail

• AXS wireless control + app customization - Clean setup with no shift cable, plus button mapping and system tuning through the AXS ecosystem for a more personalized cockpit feel
• 10-52t / 10-50t cassette compatibility (52t max) - Built to handle Eagle’s wide-range gearing for steep climbs without compromising shifting consistency
• Overload Clutch impact protection - Motor gearbox disengages during a hit to help the derailleur move out of harm’s way, then returns to position to keep riding interruptions to a minimum
• Type 3 cage damper - Improves chain management for quieter descending and more secure chain retention in choppy terrain
• Robust aluminum cage - Adds durability where rear derailleurs take the most abuse on rocks, roots, and transport
• Water and dust-proof design - Built for wet crossings, muddy rides, and post-ride washdowns without treating electronics like a liability

Compatible with the Eagle Drivetrain Ecosystem and designed for 12-speed Eagle cassettes up to 52t (B1).
