What is the LDC Nivomat?
The LDC shock absorber consists of two separate oil chambers, one large diameter piston rod, a mechanical pump with a pressure valve and a short external suspension spring.
With the oil chambers, a distinction is made between external low-pressure and internal gas-assisted high pressure chamber. When weight is put on the shock, the rod automatically pumps the oil from the low- into the high-pressure chamber. At the same time the piston rod is pushed out of the damper. This pumping process takes only as long as it takes to balance the bike. The shock absorber settles to the correct level after driving about 300 m/1000 ft.
The low-pressure-chamber is located on the outside, the high-pressure-chamber on the inside. When extra load is applied to the bike, the rod pumps oil from the middle of the low-pressure-chamber to the high-pressure-chamber – the shaft rebounds and the spring rate increases progressively.
With the LDC Nivomat Twin Shock system, the system functions are divided into two individual components. The Ecoline shock absorber is equipped with a spiral steel spring and takes over part of the overall damping. The Nivomat provides the level control and adjusts the spring rate and the additional, variable damping required depending on the load. The rider doesn’t need to manually adjust anything.
This is why the two shocks look different in the twin shock set up. But if you have a bagger, then no one can see that they are different. And if you don’t have a bagger, then it can be an interesting topic of discussion with your riding buddies. There is also a single shock option for some mono-shock bikes.
