Kryptonics was founded in 1965. In the mid-1970s the company introduced the Kryptonics Star*Trac line of wheels that were far superior to other wheels of that time. The Kryptonics urethane formula featured vastly improved rebound characteristics resulting in a much faster wheel. It was the first company to offer wheels in color coded durometers, and to use millimeter sizing. Kryptonics soon became the dominant wheel for all types of skateboarding, excelling on all types of terrain and winning more races than any other wheel brand. Now back and better than ever with an updated even faster and smoother urethane.
