Fender
From WikiPedalia
A covering for the upper part of the wheel, to protect the bicycle and rider from spray when riding in wet conditions. The best fenders run close to the wheels, and cover a large arc. They are supported by wire stays that attach to the forkends. Short fenders that attach without stays do not give enough protection to be worthwhile.
In Britain and the Commonwealth countries fenders are called "mudguards."
