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
