This makes them particularly suitable for skaters who perform frequent grinds and slides. The combination of advanced urethane technology, a performance-oriented conical shape, and the robust 101DU hardness makes these wheels a premier option for skateboarders who prioritize speed, durability, and consistent performance in their gear.
