White/65mm 100a double conical
The Rainskates Stinger wheels evolved from riders wanting a harder, faster version of the Yellow formula. The Original batch of Stingers were a Lime Green/100a Durometer wheel came out in the 59mm, and 62mm sizes. In the pursuit of even better performance, we then switched over to a newer, flat-spot resistant, "Formula X" urethane. It is slightly harder than the Yellow formula, yet just as smooth with even better speed, and 95% of the grip. "The ultimate in Speed & Confidence".
