Rings for weighting a bicycle wheel

In bicycle having a frame on which is mounted a front wheel and a rear wheel each wheel having a primary axis of rotation, said rear wheel including:

• i) a hub for mounting said rear wheel on said frame;
• ii) a rotary drive connected with a multi-speed gear in said hub;
• iii) a tire mounted on a tire rim;
• and
• iv) a wheel frame arranged to extend radially outward from said hub to said tire rim having a first and second lateral side and connected to said rotary drive;
• the improvement comprising:
• a) weighting means for adding weight to said bicycle concentrated at said rear wheel releasibly mounted on said rear wheel comprising a matched pair of rings comprising;
• i) a first ring having a continuous mass, an outer circumference and an inner circumference;
• and
• ii) a second ring having continuous mass, an outer circumference and an inner circumference;
• each of said rings having an annular surface extending between said outer circumference and an inner circumference for providing for uniform weight distribution around said rear wheel wherein said first ring is mounted on a first lateral side of said wheel frame and said second ring is mounted on a second lateral side of said wheel frame;
• and
• b) releasable clip means for mounting the weighting device on said wheel frame arranged along the primary axis rotation of the rear wheel positioned adjacent the periphery of said rear wheel whereby the first and second rings are releasibly fastened on the first and second lateral sides of said wheel frame.
