APEX XPLR REAR DERAILLEUR 

You want your bike to do everything, so you need gears that can do everything.

APEX EAGLE REAR DERAILLEUR
Eagle range on a drop bar bike? Now that’s a party. The Apex Eagle rear derailleur quietly and quickly shifts across our 12-speed Eagle cassettes, while 1x-specific chain retention technology keeps the chain where it needs to be.
