SPRING is a series of wheels for roller skates designed for recreational, sports and racing skating. This series of wheels is primarily intended for freestyle skating. Material, shape, hardness is adapted especially for asphalt and concrete surfaces with a slightly rough (uneven) surface. PU compound tolerates even lower quality surfaces well. The SPRING range of wheels excels in extremely low rolling resistance, extended service life and ensures high riding comfort. Spring wheels are equally suitable for fitness skating on rather high-quality in-line trails, where their service life can be counted on hundreds of kilometers. Set of 4 pieces.
