Öhlins TTX RT Shock Absorber YA 358
Cavitation. Something you don’t want in your shock absorber. It’s devastating because basically it means the damping is lost. Small bubbles in the oil can never create the necessary damping forces. Traditional dampers working in extreme conditions sometimes suffers from low pressure on the piston backside.
The TTX was created by Öhlins engineers to eliminate the risk for cavitation. They succeeded. With the TTX technology a positive pressure balance is created in the shock which means the risk for cavitation is gone.
TTX stands for Twin Tube with the X illustrating how the flow through the valves in the cylinder head is designed. Thanks to the twin tube technology the pressure usually created on top of the piston is transferred through the cylinder head and the adjusters for compression and rebound, then flows through the space between the inner and outer tube to the other side of the solid piston.
These equals to a pressure balance within the shock. The outer reservoir is only used to take care of the oil displacement from the piston rod and heat expansion, which is why it can be fairly small in design. Inside the reservoir there is a dividing piston between the oil and the nitrogen gas.
Piston diameter: 36 mm
Monotube high pressure gas type of shock absorber with external “piggy back” reservoir.
Adjustable rebound damping. Black adjuster on TTX36 shocks / silver adjuster on TTX GP shocks.
Adjustable compression damping. Gold adjuster on TTX36 / TTX GP shocks.
