Lacing
With classic lacing, the laces are tied by hand to form a loop. This is an advantage because the traction and pressure can individually be controlled depending on the shape of the foot. The skates with classic lacing are also particularly attractive in price.
3 Wheel
3-Wheel tracks have, as the name suggests, three rollers. Due to the "missing" roller and short bar, they are not only lighter, but also compact and very maneuverable. The three rollers are very large too, which is why they can easily reach high speeds.
ABEC 9
The classification ABEC stands for Annular Bearing Engineers Committee and classifies how fine the rolling bodies (the balls in the bearings) are worked out. In other words, the higher the ABEC level, the more precise the production. ABEC 9 bearings have consistent running characteristics such as good smoothness and smooth rotation of the rolls. Thus, the power can be transferred efficiently when driving. However, it should be noted that the smooth running of a bearing is also influenced by other factors - such as the materials used for the various components of a bearing, as well as by the choice of lubricant.
