Derailleurs

Shimano's 105 Braze-On Front Derailleur sports a cold forged-aluminum body with Shimano's extra wide-pivot design for lightning-quick and super-smooth shifts. The steel cage ensures excellent durability.

Sleek, balanced and consistent.

Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The GX Eagle derailleur gets it done with an updated cage architecture that improves chain management. Refined to work with the new 10-52T cassettes, it's also backward-compatible with 10-50T cassettes for greater versatility and incremental upgrade. It's finished with the new GX Eagle master colorway to complement any cassette and chain colorway a rider wants from the Eagle Colorsystem. - Backward-compatible—works with both 10-50T and newer 10-52T cassettes - Updated cage architecture provides better chain retention and precise shifts
