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
