Turbo wheels are a less known wheel brand, offered by Antiz Skateboards out of France. This makes them cheaper that more popular brands, but trust us, they will not dissapoint! They are 83B, so super hard. Ultra fast on concrete surface and perfect for power sliding. Skatehouse team rider tested and approved! This 55mm is the largest and widest version, we would recommend this for park shredders with deck size 8.5" or larger.
