Mud guard for bicycles

摘要

At least one inner chamber of the mud guard is covered with a gas-tight material (2,3). This a tube and conforms inherently stably to the circumference of the wheel after filling with gas. The wheel-encompassing stable form is achieved by a preformed upper and lower section by means of welding or gluing. The inherent stability is guaranteed by the gas filled chambers and these are charged or emptied through valves, and preferably inner tube valves.
