Everything has its time, so as your longboard. However good your longboard is, it will meet problems after a certain time of use like the details’ve gone wrong. Then it’s your time to look back and adjust your longboard.
Before adjusting the small components of your longboard, you must get to know it first. So today we will get into longboard bushings.
What is the bushings position in the longboard?
Each longboard consists of 2 trucks, in the front and the back. Each truck has a base plate (connect to the board) and a hanger (connect the wheels to the truck). There are pivot and kingpin to attach those parts together. The kingpin is the bolt which supports the turns and the rings around the kingpin are called the bushings.
How important is the bushings in the longboard?
There are usually 2 bushings in each truck. One in the middle of the truck for making your turns flexible and springy. The other is smaller and set right between the head of the truck and the first bushing. You can tighten or loosen it easily to adjust the quality of your ride to your interest.
- Tight: For doing tricks
- Loose: For ordinary cruising
Hardness of bushing
The bushings usually have different hardness which decides the quality of it. The measuring unit of bushings’ hardness is durometer. The symbolized letter for durometer is A. The bushings hardness usually lies between 60A and 100A. The popular material to make bushings is polyurethane.
- Low number: Soft, less stable
- High number: Hard, more stable
Shape of Bushing
There are many kinds of bushings which are in different shapes and for various functions. Here are they:
- Cone shape (cruising ): Least polyurethane. Least resistance, so quick turns.
- Barrel shape (carving, free ride, downhill): Most polyurethane. Medium resistance. Strong force for turns.
- Stepped cone (free ride): Least polyurethane. More resistance for more control than the cone shape. Better fitted.
- Double stepped (downhill): Most polyurethane. More polyurethane in the centre for better stability. Medium resistance. Strong force for turns.
As said in the picture, there are 4 types of bushings. Each type of bushings above suits the picture right above it. The shapes described as in the image. The cone shape bushings and the stepped cone are nearly the same in quality but the stepped cone is more resistance than the cone shape. Similarly, the barrel and the doubled cone are nearly the same in quality and the doubled cone is more stable because of the structure in the centre.
All of the information above I provided to you are just some references. In order to purchase your very best and super longboard, you must try out a certain number of components to judge the most suitable ones for your board condition and your own needs. Depending on your purposes, you can choose the proper bushings for yourself as described in the systematic tables above.
Have fun choosing your best components and gain great satisfaction on your choice!
