Apex Eagle Rear Derailleur - 12-Speed, Long Cage, 52t Max, Black, D1

The SRAM Apex Eagle rear derailleur quietly and quickly shifts across their 12-speed Eagle cassettes, while 1x-specific chain retention technology keeps the chain where it needs to be. It’s the best of SRAM's road and mountain bike innovations in one package.

• Compatible with 50t and 52t Eagle cassettes
• Works with SRAM 12-speed mechanical Apex and Eagle shifters
• For use with Eagle 12-Speed chain
• Roller Bearing Clutch controls chain tension for consistent shifting
• X-HORIZON straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force
• Cage Lock technology makes for fast wheel changes or chain installation
