Q: some suspension fork have commonly?
Answer: the suspension fork see: Spring / Youli rubber suspension fork and oil / gas suspension fork.
1: spring / Youli rubber suspension fork:
The performance of the front fork is determined primarily by the steel with built-in spring. Spring is cheap, and the weight is moderate, simple structure. The performance is also better with pre load adjustment of design, and is provided with a special polyurethane rubber in the outer tube and inner tube. The gum is a kind of flexible polymers, as a shock absorber and damping of elastic rebound effect, the internal structure of the shock absorber is more concise. The front fork with adjustable pre load function, can be one or more of a different nature of PU, string fixed on shock absorber, which has a larger scope of application. By adjusting the different Pu, make it play the biggest effect.
2: oil / gas suspension fork:
Such a structure is the most complex. Fork according to rider weight and riding style corresponding adjustments on the pressure. Because the air diffusion performance, so will be the same as the ball bounced fork; at this time, the oil in the fork will play an inhibitory role, to avoid shaking so badly. The biggest advantage of this structure is easy adjustment of diversification, but needs to have the professional knowledge and special tool. Good seal must be such a shock absorber, which can not leak, leakage, that is to say the mud and sand or other foreign matter, bad sealing the shock loss of function. Oil / gas pressure shock absorbers at high speed on the performance of the best collision, therefore is also evaluating for the products and design better.
