It is important to decide on the size and curvature of the board you want. The board surface is mostly made of five-layer, seven-layer or nine-layer lumber board pressed by high pressure. The board can become Canadian maple, Chinese maple or maybe birch. The choice of sandpaper needs to be "sticky" to the feet, which can increase the friction between the shoe plus the board. The size on the wheel is calculated with millimeters, the most frequent is 52-56 mm. For instance, a 5331 wheel, the best two numbers (53) will be the diameter of the steering wheel, and the back two numbers (31) are the width of the wheel. The bigger the wheel, the faster it is definitely, and the smaller wheel is more suited to playing fancy. Most bearings utilize ABEC coefficients to sole speed, which are ABEC1, ABEC3, ABEC5 along with ABEC7. For beginners, in the event you practice skateboarding on easy ground (such as marble floor or flat concrete ground), you possibly can choose ABEC1-3 bearings; in the event you practice skateboarding on rough ground (such being a road with anti-skid patterns), It is advisable to use bearings above ABEC3.
