The hanger and kingpin angle adjustment apparatus of claim 4, wherein said curving track and said support frame are formed as a single piece. 8. The hanger and kingpin angle adjustment apparatus of claim 1, further comprising a bumper attached to said curving track arcuate portion, said bumper sized to substantially cover a pair of wheels attached to said truck. 9. The hanger and kingpin angle adjustment apparatus of claim 8, wherein said bumper is wider than said pair of wheels. 10. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said curving track arcuate portion is at least as wide as said wheels and substantially covers said wheels. 11. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said curving track includes a tongue extending lengthwise from said arcuate portion opposing said flat portion and beyond a pair of wheels attached to said truck. 12. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said curving track arcuate portion is provided with indicia indicating the angular position of said hanger and kingpin angle adjustment apparatus. 13. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said curving track arcuate portion is adjustably connected to said truck base plate by a quick release. 14. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said truck base plate includes vertical sidewalls extending above said truck base plate spaced to border either side of said curving track arcuate portion. 15. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said hanger and said kingpin are constructed as a single piece of elastomeric material. 16. The hanger and kingpin angle adjustment apparatus of claim 1, wherein said curving track is made from material selected from the group consisting of stainless steel, titanium, titanium alloy, aluminum, aluminum alloy, composite, and fiberglass. 17. A skateboard, comprising, a board including a fore and an aft portion; first and second curving tracks, each of said curving tracks including a flat portion removably attached to said board fore or aft portion, respectively, and an arcuate portion extending from said flat portion, said arcuate portion including a concave bottom face, such that when said flat portion is attached to a respective board fore or aft end portion said arcuate portion projects beyond said board end portion and the highest point of said concave bottom face is at equal or greater height than said board; first and second truck assemblies, each of said truck assemblies including a truck having a hanger, a hanger pivot, a kingpin, and a truck base plate, and, first and second truck rounds, each of said first and second truck rounds including a flat bottom surface and a convex top surface having a radius of curvature approximately matching the curvature of said respective first or second curving track arcuate portion concave bottom face; and, wherein, each of said first and second truck assembly base plates is removably connected to said first or second truck round bottom surface, respectively, and each of said first and second truck round convex top surfaces is removably connectable to said first or second curving track concave bottom faces, respectively, at a plurality of user selectable positions so as to adjust the angle of said first and second hangers and kingpins in relation to said first and second curving tracks, respectively. 18.
