Description

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
