Formula Four Metallurgy & Conical Full Shape Architecture

Every structural parameter of the Conical Full shape is calculated to maximize roll velocity, prevent slide slip-outs, and provide an uncompromised lock-in on coping and rails:

• Unmatched 99A Formula Four Compound: Formulated from 100% pure polyurethane to resist flat-spots better than any other wheel on the market. The 99A durometer delivers blazing speed on smooth park concrete, while offering just enough forgiveness to absorb rugged street crust and maintain predictable traction.

• The Wide Conical Full Shape Profile: Designed with a massive 22.5mm riding surface and sharp, hand-cut squared shoulders. This wide-profile footprint distributes weight evenly for rock-solid stability at high speeds, while the flat outer walls make it effortless to lock deeply and securely into grinds without slipping out prematurely.

• True-Centric Speed Performance: Precision poured to ensure absolute balance. Formula Four urethane retains more of its original sizing and structural shape over months of heavy skating, meaning your setup rolls faster, slides further, and responds predictably during technical lines.

• The 56mm Transition & Speed Platform: Measuring 56mm, this wheel is the definitive choice for bowl riders, vert skaters, and all-terrain cruisers who need maximum top speed and rolling momentum. It clears cracks and debris effortlessly while holding speed with fewer pushes.
