Grippers™ – The original PROTO wheel, Grippers™ are as fast, smooth, and strong as they come. The spoked core provides an excellent strength the weight ratio.
Sliders™ – These wheels are the second style of PROTO wheels to come out. They share the same spoked core but are different in the urethane. Sliders™ are harder than Grippers™ and also take a longer time to wear down, even when doing high stress tricks such as sliders (hence the name) and powerslides.
