A derailleur hanger is designed to absorb any impact and strain that would be focused on the frame of a mountain bike/road bike. The derailleur hanger will bend or break off to protect the main body of the frame. Carrying a spare mech hanger is always strongly recommended, as dropout hangers are useless once bent or snapped. Not only does this prevent you from riding your bike, but will also cause damage to the frame if still used when the derailleur hanger is broken. Carrying a spare mech hanger will ensure you can get back to business without having to wait for a new one to be sent out.
