A derailleur hanger is a piece that separates your frame from your derailleur. Its purpose is to protect the rear mech and frame upon impact. If you fall while cycling and hit your derailleur, then the derailleur hanger bends and in theory, your derailleur and frame are less likely to be damaged. If this happens, you can try to realign the derailleur hanger, or buy an inexpensive replacement fromJUSCYCLING. A lot of riders carry a spare derailleur hanger while riding, just in case it breaks and needs to be replaced. Keep in mind, the derailleur hanger is a failure piece by design, and is meant to protect more expensive parts on the bicycle in the event of a crash.
