ABSTRACT:
A derailleur wheel is disclosed for use with a vehicle utilizing a sprocket chain derailing system. The derailleur wheel has a centrally disposed circular sprocket and first and second circular side faces located on each side of the circular sprocket. A plurality of cleaning brushes are secured to the side faces. The brushes preferably comprise a plurality of tufts of bristles. The cleaning bristles are radially spaced apart and extend in a radially outward direction, thereby resulting in the cleaning of the sprocket chain by the brushing of the bristles against the sprocket chain during use of the vehicle.
