Bones Wheels: X-Formula V7 Double Locks Standard 97a Size:58mm Stage 12 | Duraflex –About 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
