Formula Four Architecture & Radial Shape Dynamics

Every geometric parameter of the 55mm Team Ransom Radial is calculated to maximize roll velocity and deliver predictable sliding response across all skate spots:

• 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 retain traction on rough street crust.

• The Radial Shape Profile: Designed with a distinct, round-edge shape profile that bridges the gap between a traditional slim wheel and a wide conical cut. The widened riding surface (20.0mm) provides substantial traction and high-speed stability, while the smoothly radiused edges make it effortless to lock directly into grinds or roll over coping.

• True-Centric Speed Performance: Precision poured to ensure absolute balance. Formula Four urethane retains its original sizing and shape significantly longer than budget wheels, meaning your setup rolls faster, slides further, and responds more predictably during heavy lines.

• The 55mm Transition & Street Platform: Measuring 55mm, this sizing is the definitive choice for all-terrain riders, bowl burners, and skaters who want to maintain high speeds with fewer pushes. It rolls over cracks easily and maintains momentum effortlessly.
