Sold as a set of 4 wheels. The Nano-Rats AV4 ensure that each side of the wheel does what it's supposed to do to make skating easier and more fun. An outer edge as you're used to, a lock-on inner edge, and centrally positioned bearings give you a wheel that enhances your ride without altering the balance of your setup. Halfway between the Nano-Cubics and traditional symmetrical wheels, the Nano-Rats offer an easy way to make the Dragon Formula work even better for you.

About Dragon Formula:

The amazing new Dragon Formula™ (DF) urethane used in making these wheels is another industry-leading innovation from Powell-Peralta. DF-93A Dragons not only roll over rough terrain but also grip and slide like 99A and 101A wheels, allowing you to perform all your regular tricks and more on the wider range of skate terrains skateable by the softer 93A hardness.

Speed:

Dragons are very fast because DF-93A has a very high rebound, which is 18-20% higher than hard wheels. This higher rebound means you won't lose speed in bowls or parks like you would with a regular 93A wheel, and you'll roll much smoother and faster on rough streets and sidewalks... even in places where you used to have to walk with your board.

Grip & Slide:

Dragons slide on both rough and smooth terrain when needed. This is because Dragon Formula is not normal urethane formulated for a wheel from the mid-'90s but a unique formulation developed by our research and development group over a period of 10 years to optimize it and tune it to perfection. That's why no other skateboard wheel can perform as much as Dragon's. The slideability and grip-to-slide ratio are the result of a unique blend of high-performance materials rather than using weaker urethane with less grip and durability to get the wheel sliding.

Durability:

Dragon Formula wheels are not only smooth, fast, and slideable, they are also among the most durable wheels on the market. This makes them simultaneously great value for money, so don't think you're saving money by buying a cheap skateboard wheel with low performance. Choose Dragon Formula wheels and have longer-lasting fun while skating.
