- 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
- 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
- Roller Bearing Clutch controls chain tension for consistent shifting
- Works with 12-speed mechanical Apex and Eagle shifters
- Compatible with 50T and 52T Eagle cassettes
- Use with Eagle chain
