Bones Wheels: X-Formula V6 Widecut 99a Size:55mm and thanks to the temperatureAbout 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. X Formula rolls much smoother and faster on all terrains because it absorbs vibration and softens impacts much better than any other wheel in the market. Grip
