SRAM Apex Eagle D1 Max 52T 12 Speed Rear Derailleur (Mechanical)

Eagle range on a drop bar bike? Now that’s a party.

It’s the best of our road and mountain bike innovations in one package.Compatible with 50T and 52T Eagle cassettesWorks with 12-speed mechanical Apex and Eagle shiftersUse with Eagle chainRoller Bearing Clutch controls chain tension for consistent shiftingX-HORIZON straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift forceCage Lock technology makes for fast wheel changes or chain installation
