The Antik Reckless Morph Wheels are a game changer! Dual stacked urethane in multiple hardnesses allows you to have the hard fast roll for performance and speed while still providing grip and edge control. With a linked one-piece core, the Morph wheel gives less flex than standard wheels and gives you the faster roll you need to beat out the competition. Once again, Antik comes through with a great wheel for roller derby. This wheel is "slim" 59mm x 38mm.
Each wheel has two hardnesses, which is determined by color
Green Core - 84A (pink) and 88A (orange)
Pink Core - 88A (orange) and 91A (yellow)
Purple Core - 88A (orange) and 93A (blue)
Blue Core - 91A (light yellow) and 95A (dark yellow)
Yellow Core - 93A (blue) and 97A (green)
