Celebrating the career of legendary pro Tom Knox in the 1980's, Slime Balls reissues the signature Firepit pro model wheels in a conventionally white urethane, measuring 60mm in diameter with a 97a durometer to handle rougher terrain with ease. Highlighting bold, classic artwork by Jim Phillips on each side, one graphic is presented in full color while the other displays a black and white illustration - allowing the rider to personalize their setup with either design.
