With the Bones X Formula V5 Sidecut, you'll roll even smoother and faster on uneven roads and sidewalks, but these wheels also grip and slide like the harder durometers you know and love from Bones!
 The new signature X-Formula urethane combines a unique blend of high-performance materials to provide the best all-around performance on rough surfaces. These wheels, however, offer longer lifespans and the same sliding performance despite the lower stiffness.
