What is a Derailleur Hanger?

A derailleur hanger is a small, often overlooked part of a bicycle that connects the rear derailleur to the bike frame. It serves as a mounting point for the derailleur, allowing it to shift the chain between different gears on the cassette. The hanger's design is critical, as it helps maintain the alignment of the derailleur with the gears.

Key Features of a Derailleur Hanger
