About X-Formula:

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 & Slide:The slide-ability comes from its unique blend of high-performance materials. X-Formula will slide when you ask it to, and grip when you need it most. This is because X-Formula is specially formulated for any terrain. It has been developed over a ten-year period to optimize performance and fine-tuned to perfection. X-Formula is a unique product
