Bones Wheels: 54mm 95a X-Formula Sidecut Phase Five Concave: NessieAbout X Formula About: The amazing new X Formula (XF) is another industry leading innovation from the BONES WHEELS factory. X Formula rolls over rough terrain like softer wheels do, but slides much like a harder wheel will. Speed: X Formula is extremely fast because it has a super high rebound.
