These are protective components typically found on vehicles, particularly bicycles, motorcycles, and some types of trailers. They are designed to shield the vehicle and its occupants, as well as other road users, from water, mud, and other debris thrown up by the tires. An example would be their use on a touring bicycle to enhance rider comfort in wet conditions.
The implementation of these parts offers several advantages. Enhanced protection from the elements preserves the cleanliness of the vehicle and clothing of the user. In a historical context, simpler materials were initially used, with advancements in metallurgy allowing for more durable and corrosion-resistant solutions. The introduction of such materials also improved longevity and reduced maintenance requirements, leading to broader adoption.
