WheelsPro Scooter wheels come in a variety urethane hardness ratings - measured by the Durometer (example is a hardness rating of 88A). The higher the rating, the hard the urethane. A softer rating provides more wheel grip on riding surfaces, where as the advantage of a harder rating is more speed.
Scooter wheels come in a variety of hub types (plastic spokes, alloy spokes, alloy solid core, hollow core, etc) and can be categorized by the two available wheel diameters:
• 100mm Scooter Wheels: Compatible with any scooter. This size wheel is generally found on Razor’s base models like the Ultra Pro Series and Pro X, MGP base models like the MGP Pro and MGP Team. We carry 100mm wheels by brands like Madd Gear, Lucky, Phoenix, Eagle.
• 110mm Scooter Wheels: Not compatible with all scooters, but generally fit scooters that use threadless forks. Before you purchase 110mm wheels, be sure they will fit your scooter. Because of the larger surface area on the 110mm wheels, they are generally faster than 100mm wheels. We carry top 110mm scooter wheel brands like MGP, Eagle, Fasen, Lucky, Phoenix Proto, and River.
