Powerslide One wheels The wheels are one of the most important parts of your inline skates; they can drastically change your skating experience. The One Stargaze skate features Powerslide One wheels. They have a wheel hardness of 85A, allowing children to skate longer distances on good surfaces. The wheels have a diameter of 70 mm. WCD Wicked ABEC 5 bearings. ABEC is a rating system for bearing tolerances. The higher the number on a scale of 1 to 11, in this case ABEC 5, the smaller the bearing tolerance. Smaller tolerances mean your bearing will spin faster and longer. The bearings in this skate therefore ensure a longer rolling time. Hours of fun.
