With a weight of only 220 grams per stunt scooter wheel (with bearings) - The Root stunt scooter wheels are among the lightest wheels ever to hit the market. Thanks to the use of high grade 6061 aluminum and a unique construction.
The Air wheels from Root are made with hollowcore technology. This is essentially air trapped in the core between two sturdy aluminum plates. This not only creates a light construction but also makes it very strong.
The PU formula that Root uses has rapidly become a favorite amongst many pro riders. It makes the stunt scooter wheel super fast and strong.
