What are mono tube or itro gas filled shocks?
The heat generated in the twin-tube shock tends to get trapped within the walls of the shock absorber body, reducing its effectiveness in controlling wheel motions. The mono-tube shock absorber uses a piston traveling within a single tube that is exposed more directly to the air. The general advantages and disadvantages of this design are: By getting rid of heat more easily, mono-tube shocks are less susceptible to overheating on rough roads. They are more expensive to manufacture however, and the tolerances must be higher and the seals better to keep the oil inside the shock body. To prevent foaming and bubbles in the oil, which degrades shock-absorber performance, a gas-filled mono-tube shock has a chamber of high-pressure nitrogen above the oil chamber. This high-pressure gas makes it difficult for bubbles to form in the oil, even when the shock absorber moves in and out very quickly, as it might while traveling rapidly on a very rough or washboard road.
