Abstract: The present invention provides a strap, preferably made of pliant leather, with a method of easily and securely attaching its two ends together such that it forms a loop around the hub of a bicycle wheel. As the bicycle wheel spins, the loop naturally moves about on the hub and removes oil and dirt from the hub. The strap includes a pattern of cuts along its two long edges and has a rough inner surface to assist in cleaning and includes an optically reflective outer surface for rider safety. The size of the strap is approximately 16 cm long by 1.4 cm wide by 1 mm thick so that it is large enough to freely spin on the hub yet not too large as to strike the spokes and create unwanted noise. The method of attaching its two ends comprise one or more holes at one end of the strap and an arrowhead with one or more pairs of notches at the other end of the strap. In connecting different notches and holes together, different sized loops may be formed.
