Evolve Skateboards has designed the perfect wheel called the F1 in cooperation with Abec 11. Due to the large diameter of 107mm, this wheel is perfect for driving at high speeds. The wheel is made of the world famous Reflex Formula 74a of Abec 11. This ensures that you can make smooth carves and experience every turn as if you are surfing down the streets. The set is plug & play and includes 4x Evolve Abec 11 F1 wheels. You can simply mount the set on your standard 32T or 38T gears. You don't need a special set of gears.
