The Piper Freaky Fast Wheels are what they say they are! These wheels are made for speed skaters, jammers, or skaters who just love passing everyone up in the rink. Piper's Race Thane wheel formula provides a smooth, grippy ride, while a tri-spoked nylon composite core keeps weight low and maximizes energy return. A curved speed lip prevents getting caught in corners without compromising control, and two different hardness options allow you to fine-tune your grip and roll speed.
