Q: There are several common suspension fork ?
     
A: See the suspension fork are: spring / Urethane suspension fork and oil / pneumatic suspension fork .
    1 : Spring / Urethane suspension fork :
    Such built mainly by the performance of the fork spring steel is determined . Spring cheap, and moderate weight , simple structure. Re better performance of the design as well as with pre- load adjustment , and a special Urethane between the inner and outer tubes . Urethane is a flexible polymer , the role of the elastic rebound and damping shock absorbers as to enable the internal structure of shock absorbers and more concise. Fork with adjustable pre-load function can be one or more blocks of different nature Urethane , fixed in suspension in the series , it has a larger scope . By adjusting the different Urethane , so as to maximize the effect.
     
    2 : Oil / Air suspension fork :
    Such fork structure is most complex. Fork needs based on rider weight and riding styles on the pressure adjusted accordingly. As the air diffuser is better , so as the fork will bounce like a ball ; then , the oil inside the fork will play the role of inhibition in order to avoid too much vibration . The biggest advantage of this structure is the adjustability of the suspension has diversified , but need to have expertise and specialized tools . Such suspension must be sealed well, so it does not leak , leak , that sediment or other foreign matter , bad seal will shock absorbers loss of function. Oil / gas pressure shock absorbers in high-speed collision of the best performing large , and therefore are rated better products and designs.
