UrbanSkaters

Wheel hardness is measured using the A scale (76A for example). The higher the number the harder the wheel, with lower numbers indicating software wheels. Hard wheels are generally more durable and faster, but software wheels offer better grip and you don’t feel the bumps in the roads so much! Other terms you might hear when choosing wheels are Elliptic and Rounded profiles. Elliptic profiles minimize friction (less stable) and allow for a faster ride, but if you’re looking for better grip and a more stable ride; then rounded profiles are for you.

Wheel sizes differ greatly depending on the type of inline skates you choose. Putting it simply, the bigger the wheels the faster the skates (like recreational and speed skates for example). Smaller wheels on the other hand are better suited for maneuverability and faster acceleration (like aggressive skates).

54-56mm for aggressive skates
68-72mm for artistic inline skates
76-80mm for hockey, freestyle and slalom skates
80-110mm for recreational and speed skates
