The Bravvos Drop Out Derailleur D05 is a bicycle rear derailleur hanger (dropout).
It is a small metal mounting piece that connects your rear derailleur to the bike frame.
Its main job is to:
Hold the derailleur in the correct position
Allow precise gear shifting
Act as a “sacrificial part” that bends or breaks instead of damaging the frame during impact or crashes
Dropouts like this are very common on MTB, hybrid, and entry-level bikes, and they are usually model-specific or semi-universal depending on frame design.
(Bravvos also lists similar “Drop Out Derailleur” parts in their range used for frame compatibility replacements.)
