Venice, CA - February 14, 2008 -- In concurrence with skateboarding's perpetual evolution and culture revolutionizing image, Dark Horse Distribution defines a new trend once again with the introduction of specialized wheels challenging the industry to keep up.

Marble Wheel Co. has created multicolored wheels including camo, candy corn, rainbow, salmon, rasta, skulls, checkers, and tie-dye. Making urethane attractive, these wheels feature both unique designs and bright colors blending across the wheel. Made in the USA and produced without lead, they are available in three sizes: 50mm, 52mm, and 53mm. Packaged in marble bags, they offer a unique visual experience both on and off the skateboard. Marble Wheel Co. products are the first of their kind.

Pioneered by Grind King owner Donald Cassel, Dark Horse has set new precedents in style and technology over the years. Grind King popularized colored trucks and was the first truck company to put graphics on trucks. Donald Cassel has been innovating and impacting the skateboarding industry for 20 years starting with the release of the world's first kingpin made specifically for grinds. The Dark Horse Distribution umbrella also includes the brands Dogtown, Termite, and GromMom.

Marble Wheel Co. wheels are now available.
