FIG. 1 is a perspective view of a sprocket wheel for bicycle showing my new design;

The phantom lines shown as a long dash-short dash form serve as surface shading to show the character and contour of surfaces and to distinguish between open and solid areas of the article. The portions of the article that are shaded with phantom lines and/or bounded by solid lines form the claimed design. Alternatively, the uniformly even broken lines in the drawings illustrate portions of the sprocket wheel for bicycle that forms no part of the claimed design.
