Illuminating the ground beneath your deck, Slime Balls delivers the Chrome Surfer OG cruiser skateboard wheels in a 78a durometer and a 66mm diameter with futuristic LED Light Ups technology built inside. Utilizing a transparent urethane, the special conical-shaped wheels feature LED lights that charge from special spacers between the included Bronson G2 bearings as they roll - so the farther you go, the brighter your ride shines.
