UC Undercover Apex wheels are made for speed. The Aluminum hub has been developed for maximum performance. The stiffness of the ALU hub brings a faster roll and an increased stability to your wheels. It will also change your weight distribution across the wheels improving the rolling effect. The aluminum core also provides a better spinning effect and a greater consistency on the edge-to-edge transfer. The interlock core design provides a tough bonding between the new 88A UHR compound and the core. Long-lasting, fast as hell but still super grippy. This wheel was specially designed for park skating.
