The BONES Skatepark Formula Sidecuts SPF 84B P5 54mm skateboard wheels are built for skaters who want maximum speed, high rebound response, and consistent slide control on smooth skatepark terrain. The SPF urethane is engineered specifically for transition, bowls, ramps, and polished concrete where speed and flatspot resistance matter most.
The P5 Sidecut shape features a wide riding surface, sidecut profile, and supportive lock-in feel designed for stability, smooth control, and predictable slides at high speed. The wider shape helps maintain confidence through bowls, transition, and fast park lines while reducing drag during grinds.
The 54mm size offers increased speed and smoother roll while still remaining responsive for technical skating. It provides a strong balance of stability, control, and momentum for mixed park and transition skating, making it one of the most popular wheel sizes for all-around skating.
84B SPF wheels are built for maximum hardness, speed, and slide control on smooth skatepark terrain. The Skatepark Formula urethane features extremely high rebound for faster roll speed and quicker response while maintaining excellent slide control, high abrasion resistance, and exceptional resistance to flatspotting.
