The ornamental design for a spoke for bicyclewheels, substantially as shown and described.
FIG. 1 is a perspective view;
FIG. 2 is a front view (the front view is a mirror image of the back view);
FIG. 3 is a left side view (the left side is a mirror image of the right side); and,
FIG. 4 is a cross sectional view taken along line 4—4 in FIG. 3.
The central milled portion, shown shaded with straight lines, is obtained by milling the surface of the dark metallic spoke, which is shown shaded with stippling. The broken line showing of the spoke ends form no part of the claimed design.
