Pro Scooter wheels come in different diameters: 100mm,110mm, 120mm, and 125mm. Riders tell us that larger scooter wheels are faster.
All scooter wheels have a solid "tire" made of Urethane. The hardness of the Urethane is indicated by the Durometer. For example "88A". The higher the Durometer, the harder the Urethane. Softer Urethane gives the wheel more grip. Harder Urethane provides more speed.
All wheels are sold per piece. Some pro scooter wheels include bearings. See description for details.
