Bones X-Formula V6 Widecuts 97A Skate Wheels The Bones X-Formula V6 Widecuts 97A Wheels combine the smoother ride of a softer wheel with the slide characteristics of a harder street wheel. Bones&'; X-Formula(TM) uses a high-rebound compound designed to absorb vibration and soften impacts while maintaining speed across rough terrain. The V6 Widecuts shape adds a wider contact patch with sidecut walls for greater stability and less drag during longer grinds. With a 97A hardness and smooth surface, they&';re built for street skating with a balance of speed, grip, slide, and impact absorption.
