The quality of the skateboard must be different, what about the other products?
Some skateboards are called professional boards. In my eyes, it's skateboarding. This kind of board divides the whole board and the assembly board. The whole board was prepared by the board for people who had just started skateboarding. The assembly board is a skateboard that the slider buys from different vendors according to individual preferences and is assembled together.Board (deck): generally seven layers of wood pressing (partial cold pressing, hot pressing). Cold press well. I know the domestic Black Knight, this brand is good. The best material is the hard rock maple, if you want it to be more firm can choose between light, carbon fiber (rare, I only saw in a magazine). The general entry of the whole plate of hard rock maple do not choose board material, generally choose elastic almost sugar maple.
Generally available in the supermarket to buy skateboards, the price is very cheap, at most 300. The quality of these skateboards is not so good, if you play every day, and then practice some work, can fight for six months, good. These boards are generally referred to as toy boards.
Bracket (truck): professional address called "bridge"". Bridge is good or bad in weight, because the bridge is all metal parts, so it will be very heavy. So the lighter the bridge, the better, but still strong enough. Generally speaking, the bridge is made of aluminum alloy. But there are other materials, such as: titanium alloy (China skateboard nets see, estimated that it is not cheap). Then there is the elasticity of the PU (the only non-metallic component on the bridge). The better the elasticity, the better the bridge. But attention is elasticity, not hardness. Some people like hard PU, and others like soft ones. It's based on personal preference. Personally, I like the independent (Indy) bridgeBearings (bearing): Generally speaking, the sooner the better. The precision of the bearing is divided by ABEC-7 and abec-5. 7 of high precision, speed, but easy to bad. 5, on the contrary. In short, fast and sturdy bearings are the best.Wheel (wheel): good elasticity indicates good wheels. There are wheels, size, hard and soft difference, this is based on personal preferences.
