SRAM 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.

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
