     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new bicycle braking system embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
     As best illustrated in FIGS. 1 through 6, the cycle braking system  10  generally comprises a pair of braking assemblies  20  positioned on opposite sides of a wheel  2  having a rim  4 . Each braking assembly generally includes a casing  22  designed for coupling to the cycle  6 . The casing includes a pair of angled slots  24  and a cylindrical brake pad  26 . The brake pad includes opposite sides  27  and  28  and an outer perimeter wall  29  extending between the opposite sides. The brake pad further includes an axle  30  having opposite ends  31  extending outwardly from the opposite sides of the brake pad. Each of the opposite ends  31  of the brake pad are positioned in an associated one of the angled slots in the casing. 
     The angled slots each includes a first end  32  and a second end  33 . The casing is positioned such that the first ends of the angled slots are positioned proximate the rim of the wheel such that the brake pad contacts the rim when the opposite ends of the axle are positioned proximate the first ends of the angled slots. The second ends are positioned such that the brake pad is positioned in a spaced relationship to the rim when the opposite ends of the axle are positioned proximate the second ends of the angled slots. 
     A cable assembly  40  is coupled to each of the braking assemblies such that the cable assembly is designed for selectively urging the brake pads of each brake assembly into contact with opposite sides of the rim such that a portion of the rim is clamped between the brake pads. The cylindrical nature of the brake pads permits clamping such that the brake pads rotate to facilitate continued pedaling of the cycle during braking for enhancing a user&#39;s control of the cycle. 
     Each braking assembly includes a pair of biasing assemblies  42  coupled to the casing. Each biasing assembly is positioned within a respective one of the angled slots and in contact with an associated one of the opposite ends of the axle for biasing the brake pad towards the second ends of the angled slots. Thus, the brake pad is prevented from contacting the rim of the wheel when the cable assembly is not actuated. 
     The cable assembly includes a main cable  44 , the cable  44  includes a first portion  45  divided into two strands  46 . Each of the strands includes a pair of free ends  48 . Each free end forms a loop  49  engaged to a respective one of the opposite ends of a respective one of the axles. 
     The cable assembly further includes an arcuate main spacer  50  positioned between the strands for dividing the strands and positioning the strands on opposite sides of the wheel. The cable assembly further includes a pair of arcuate casing spacers  52  each being positioned between an associated pair of the free ends for positioning the associated free ends on opposite sides of the casing and preventing the free ends from contacting the casing. 
     Each opposite end of the axle includes a groove  54  designed for receiving a portion of a respective one of the loops such that the respective loop is engaged to the axle. 
     Each casing includes a clamping portion  56  having a frame receiving portion  57  and a clamping member  58 . The frame receiving portion is designed for abutting a frame  8  of the cycle and the clamping member is engageable to the frame receiving portion. The clamping portion is tightened such that the clamping portion clamps the frame between the frame receiving portion and the clamping member, thus engaging the casing to the frame. Each clamping member is coupled to the frame receiving portion by a plurality of screws  59 . 
     Each brake pad includes a bearing  60  rotationally coupled to the axle. Each brake pad further includes a frictional material  61  extending radially outward from the bearing. Each bearing includes a plurality of teeth  62  having a pair of ends  63 . The teeth extend across an outer surface of the bearing for preventing rotation of the frictional material relative to the bearing. 
     Each axle includes a pair of separable portions  64 . Each portion includes a disc-shaped guard portion  66  for covering the ends of the teeth for preventing the ends from snagging on the casing. 
     In an embodiment, a single brake assembly is used and the cable assembly requires only one casing spacer. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
