Sram SX Eagle Aluminum Rear Derailleur - 12 Speed

This new SX Eagle derailleur is your entry point to the SRAM Eagle Ecosystem. Sharing many features with the rest of the Eagle Ecosystem like the proven SRAM 1x-specific X-HORIZON™ body design, it can accommodate both 11-50T and 10-50T cassettes. The SX Eagle is cross compatible with much of the Eagle Ecosystem, making it easy to personalize and upgrading your ride when you are ready.
