Here at Skatehut we have an ever growing selection of Inline Wheels. Wheels are almost universally made of polyurethane (a kind of durable plastic). In general, the bigger the wheel, the faster the skate. However, large wheels take more energy to start rolling whereas smaller wheels allow faster acceleration, maneuverability, and a lower center of gravity.
Wheel sizes vary depending on the skating style:
Aggressive skating: 44–59mm
Roller hockey skating: 47–80mm
Artistic inline skating: 68–72mm
Freestyle slalom skating and downhill skating: 72–80mm
