Rullapyöräkokojen

Rullapyöräkokojen refers to the measurement of rollerblade wheel sizes. This measurement is typically expressed in millimeters (mm) and indicates the diameter of the wheel. Larger wheel diameters generally result in higher top speeds and a smoother ride over rougher surfaces, as the wheel can roll over obstacles more easily. Conversely, smaller wheels offer more maneuverability and quicker acceleration, making them suitable for certain types of skating like slalom or aggressive inline skating.

The most common wheel sizes for recreational and fitness inline skates range from 80mm to 90mm. Speed skates and marathon skates often feature much larger wheels, sometimes up to 125mm, to maximize speed and efficiency. Aggressive inline skates, designed for tricks and grinds, typically use smaller, harder wheels, often around 55mm to 60mm, for better control and durability.

When choosing rollerblades, the wheel size is a crucial factor to consider based on the intended use. Skaters should also be aware of the maximum wheel size their skate frame can accommodate, as installing wheels that are too large can affect performance and potentially damage the equipment. The hardness of the wheel, measured on the Durometer (often indicated by an "A" rating, e.g., 85A), is another important specification that influences grip and wear.
