Set of 4 wheels. These wheels come with ABEC-9 high-speed steel bearings and spacers, which are pre-installed. They roll smoothly and are durable for street skating, providing a very smooth ride on skate park surfaces. Ideal for penny boards, these wheels are suitable for cruising and basic street tricks. They perform well on smooth concrete or asphalt surfaces. The packaging is neat and secure, making it suitable for gifting. The bearings are pre-lubricated, offering improved speed and durability compared to standard bearings.
