SRAM, Apex Eagle D1, Rear Derailleur, Speed: 12, Black

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
• Use with Eagle 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
• SRAM Model ID: RD-APX-152-D1
