A cover for the chain and front and rear gear assemblies of a drive train of a bicycle, including;
- an imperforate, closed continuous sidewall formed of a flexible fabric and defining an oblong, bag-like enclosure;
- said continuous sidewall having a first continuous edge defining an oblong opening to said enclosure;
- said enclosure having a length greater than the inclusive distance between the front and rear gear assemblies of the drive train of the bicycle and a width greater than the distance between vertically opposed portions of the chain of the drive train of the bicycle;
- a rear portion of said opening adapted to be secured about the rear gear assembly of the drive train of the bicycle and a front portion of said opening adapted to be secured about the front gear assembly of the drive train of the bicycle to enclose said drive train;
- and,
- means for contracting said opening to a circumferential dimension less that the circumference of said closed continuous sidewall.
