Let’s have a look at the merits and demerits of the twin-tube shock absorber.
Merits
*It is easier to secure sufficient stroke, because the oil and gas chambers are separated and not positioned serially.
*The base valve enables to keep gas pressure low, allowing for a more comfortable ride.
*Low gas pressure avoids stress on seals and keeps friction levels low.
*Compared to the inverted type, friction can be suppressed.
*Even if the shell case is slightly damaged, the function of the shock absorber remains unaffected.
*Superior manufacturing processes allow to keep production costs low.
Demerits
*Oil capacity is not as large as the mono-tube.
*Size of the piston valve is not as large as the mono-tube.
*The structure restricts installation angles.
*The oil and gas chambers are not separated, so there is a possibility for aeration to occur.
