SRAM Apex Eagle D1 12-speed rear Derailleur

Eagle range on a drop bar bike? Now that's a party. The Apex Eagle rear derailleur quietly and quickly shifts across 12-speed Eagle cassettes, while 1x-specific chain retention technology keeps the chain where it needs to be. It's the best of road and mountain bike innovations in one package. 

• Compatible with 50T and 52T Eagle cassettes
  
• Works with 12-speed mechanical Apex and Eagle shifters
