Any owner of a two-wheeled bike, sooner or later, faced with the fact that rear shock for the bike starts to creak. This problem may occur for different reasons. To identify the exact location of the noise should carefully listen to the sounds, not forgetting to explore the frame for defects. Generally, squeaks are caused by lack of lubricant the troubled spot because it dries. In addition, the problem may appear because of installation of non-original parts, loosening, deposits of dust and dirt.
This complex part includes a lot of different elements. The first thing you need to do at occurrence of extraneous noise, disassemble the hub and check the grease. In case drying is necessary to apply a new layer. Before doing this be sure to rinse and dry all parts. Then the rear shock for the bike is going in reverse order. Such a procedure allows to improve the smoothness of interaction between the elements, prolonging their service life. For all types of bikes fits Teflon grease. In addition, the appearance of scratches, inspect the plug, as often the fault is associated with it.
The predominant part of the shock absorbers are the settings proper adjustment of which makes it possible to better monitor and control the speed. In addition, the reduced wear of the node. Consider the sequence and features of this operation.
This process requires taking into account three main controls. The first one is the pre-load. This parameter represents the resistance received by the fork under the weight of a rider. Accordingly, the greater the mass, the higher should be the degree of pre-load. For elements with a spring of helical type, this means an increase or decrease of flexibility, and pneumatic counterparts – more pressure.

The Second point – the compression damping that arises from the inner part of the shock absorber, responsible for the regulation of lubricant flow through the holes. This parameter affects the node during compression without affecting pre-load. The more pressure applied, the harder it will be to control the bike.
Finally, the damping of the recoil (similar to an internal compression system). This point affects the rear shock on the bike only during its return to the initial position. If this option is strengthened excessively, the fork in his position will get slower. This solution is appropriate when there is significant resistance of the bike, especially on bumps and turns.
It is best to carry out such work alone, but one to cope quite capable. The first thing measured is the inner part, which is a brilliant element that is moved in the middle of the body. The resulting value divide by 4. For optimal functionality requires a subsidence with the rate of 25 %. Mountain bikes for downhill, this parameter can be 30 %.
Almost any modern rear shock for a Bicycle equipped with a small inflatable ring or a special stopper, designed to control subsidence. If no such element, it is possible to tie the elastic. It is not recommended to use this cable, which collects dirt and scratch the surface. In the results, you may need not only repair, but also replace the rear shock on the bike. Switch damping compression is set to descent mode, the ring is removed, the bike fits neatly on a flat surface. After that you should take position for the ride. To correctly select a constant weight, during the procedure, try not to shake valmasino.
Carefully check the degree of sagging, watching the distance the ring travels. If the index is greater than or less than a quarter of the length, start configuration of psi. Usually air dampers 25 % sagging give 150-200 pounds per square inch.
On the spiral counterparts made small adjustments by using disks pre-load. Depending on the weight of the rider for the correct adjustment may require a spiral with more or less elastic ratio. Purchase them available in specialized stores.
Rear shock for the bike, depending on modification, is equipped with a switch type or CTD suspension settings (damping). In the first case, it is sufficient to adjust the item according to the surrounding landscape.
If you have the settings, proceed as follows:
How to grease the rear shock on the bike? In this process, particular difficulties there. Oil is poured into the plug, the liquid lubricant is placed directly in the cushioning element. The pre-absorber disassembled, all parts washed and carefully dried. Then a layer of suitable lubrication, followed by Assembly.
If the problem is a squeak in the fork, disassembly of items is performed as follows:
As recommended by the experts for maintaining the bike-cars in optimal condition, it is desirable to lubricate the shock absorbers for every day while riding in the rain and once a week, if the weather is Sunny. As processing materials use special spray nozzles, manufacturer's recommended oil or multipurpose Teflon grease.
Above, we considered why the squeaking rear shock on the bike and how to solve this problem. Timely lubrication will extend the service life of parts, improve the driving comfort and eliminates extraneous noise. By following these recommendations, also easy to produce the correct setting of the shock absorber, which optimizes the process of moving, depending on the mass of the cyclist and features of the road.
