Introducing the groundbreaking Dragon Formula (DF) Urethane, a new product from Powell - Peralta that is leading the industry with its innovative design. These DF-93A Dragons wheels boast the ability to roll smoothly over rough terrain while also gripping and sliding like the 99A and 101A wheels, allowing skaters to perform their usual tricks on a wider variety of skate surfaces due to their softer 93A hardness. Speed is a key feature of the Dragons, as the DF-93A has an industry-leading super high rebound of 18-20% higher than that of hard wheels. This means that skaters won't lose speed in bowls or parks as they would with ordinary 93A wheels, and will experience smoother and faster rolling on rough streets and sidewalks, even in places where they used to have to walk their board. The Dragons are designed to slide on both rough and smooth surfaces while also providing ample grip when needed. The Dragon Formula was developed over a ten-year period to optimize and fine-tune it to perfection, making it unlike any other mid-90's wheel formula. These Dragons wheels are unparalleled in their performance and abilities. Durability is also a key feature of Dragon Formula. Its unique blend of high-performance materials creates a urethane that wears away gradually, resulting in slidability without flat spots. The Dragons are long-lasting, making them a better skating investment and a great value overall.
