BONES WHEELS - CHRIS LILLEY "BLACK CAT" X-FORMULA X99 "V5 SIDECUT" WHEELS (56MM)

Conquer rugged street terrain, blast through deep concrete transitions, and lock seamlessly into long ledge lines with the Bones Wheels Chris Lilley "Black Cat" X-Formula X99 Wheels. Poured in the legendary Bones manufacturing facility in Ventura, California, as a signature pro model for street powerhouse Chris Lilley, this 4-pack features an alternative, dark "Black Cat" graphic concept that looks incredible on the shelf and aggressive on your board.

Driven by the game-changing X-Formula™ (XF) compound, these wheels break every traditional rule of skateboard urethane engineering. They are scientifically optimized to roll smoothly and absorb joint-numbing street vibration like a softer wheel while sliding cleanly with the crisp, predictable response of a harder wheel. Cut to an all-terrain 56mm diameter and poured in a highly responsive 99A durometer (X99), this setup utilizes Bones' high-stability V5 Sidecut geometry to create the ultimate high-velocity street and park weapon.

The Science of X-Formula™ X99 Compound & V5 Sidecut Geometry

Every structural parameter of Chris Lilley's signature wheel is calculated to maximize roll velocity, absorb harsh road friction, and optimize slide flow:

• The X99 Pro Hardness Breakthrough: Featuring an ultra-high rebound material structure, the X99 compound delivers the blistering top-end speed of a traditional 101A hard wheel on smooth park concrete, yet acts like an impact absorber on rough ground. It cushions harsh road crust and dampens high-impact street landings, significantly reducing physical leg fatigue.

• Flawless Grip-to-Slide Continuum: Engineered to grip tightly when you need sharp cornering control, yet break loose into a smooth, predictable slide the second you initiate a power slide, blunt, or nose slide. Unlike cheap soft wheels that bounce or stick violently on rails and ledge caps, this compound slides cleanly without stalling out.

• The V5 Sidecut Architecture: Designed with specialized sidecut walls and a narrower 15.5mm riding surface. The flat sidecut shoulders decrease drag, provide exceptional stability at high speeds, and make it effortless to lock deeply and securely into round rails, ledge angles, or pool coping for longer, more stable grinds.

• Advanced Flat-Spot Resistance: Built using premium, high-molecular materials that resist flat-spotting better than any budget wheel on the market. They maintain absolute geometric roundness over months of heavy street abuse, preserving a fast, true roll over their entire lifespan.

• High-Velocity 56mm Frame: Measuring 56mm x 32mm, this sizing is the definitive choice for modern all-terrain skaters and transition technicians who demand maximum speed conservation, effortless roll-over clearance on rough pavement, and plenty of urethane to last through months of heavy sessions.
