How to lubricate front shock absorbers on a bicycle

Is it worth it to repair a bicycle fork yourself??

Of course, without the appropriate experience and skills in repairing bicycles, it is better not to take risks and turn to competent specialists. But over time, every cyclist who is more or less interested in his vehicle begins to understand the intricacies, remember the name of the parts and their functions, and feel the root of the problems. Therefore, over time, even such a difficult thing as repairing a plug can become an easy procedure.

Difficulties may arise due to the design features of the fork itself or its breakage.

As a rule, the owners are divided into two types: some prefer to ride a bike until all systems fail and it will be impossible to save such a patient, others carefully monitor the condition of the bike and prevent any breakdowns.

How to adjust the rear shock on a bike?

This process requires accounting for three main controls. The first is preloading. This parameter is the resistance received by the fork under the rider’s weight. Accordingly, the greater the mass, the higher the degree of preload should be. For elements with a spiral type spring, this means an increase or decrease in elasticity, and for pneumatic analogs, more pressure.

The second point is compression damping, which arises from the inside of the shock absorber, is responsible for regulating the flow of lubricant through special holes. This figure affects the knot during compression without affecting the preload. The more pressure is applied, the harder it will be to control the bike.

Finally, recoil damping (analogous to the internal compression system). This moment only affects the rear shock on the bike during its return to its original position. If this parameter is excessively strengthened, the fork will sit in its position more slowly. This solution is appropriate when there is significant resistance from the bike, especially on bumps and turns.

Compression and damping

The rear shock absorber for a bicycle, depending on the modification, is equipped with a CTD switch or suspension (damping) settings. In the first case, it is enough to adjust the element according to the surrounding landscape.

If there are settings, proceed as follows:

  • Pay attention to the number of adjustment range modes. To do this, scroll the disc back and forth, counting the clicks produced.
  • If you do not want to experiment with finding the optimal value, set the disk to medium.
  • Extreme settings are rarely suitable for athletes.
  • When driving, memorize the route and the necessary setting values ​​in order to determine the process of the suspension functioning.

They are simple to construct and not expensive. As for reliability, it depends on the way of operation. If serviced and monitored on time, it can serve for a long time and without problems. But as a rule, on inexpensive ones, backlash of the front fork legs, rusting of the legs and other problems are inevitable soon.

Further instructions, suitable for almost any spring-elastic fork, as their design is identical.


How to lubricate the rear shock on a bike? There are no particular difficulties in this process. Oil is poured into the fork and liquid lubricant is poured directly into the shock absorber. The shock absorber is pre-disassembled, all parts are washed and thoroughly dried. Then a layer of suitable lubricant is applied, after which the assembly is carried out.

If there is a squeak problem in the plug, disassemble the part as follows:

  • The element is cleaned, the wheel is dismantled.
  • The bolts holding the fork in the rods are unscrewed, the regulator is removed.
  • Next, remove the brake system.
  • The remnants of the old grease are removed from the rods.
  • Dismantle the stuffing box rings.
  • The inner cavities of the fork are thoroughly wiped.
  • Grease is applied to the oil seals, oil is poured into the pants of the element.
  • Assemble the assembly in reverse order.

As experts recommend, to keep the bike in optimal condition, it is advisable to lubricate the shock absorbers every day when riding in the rain and once a week if the weather is sunny. Use special aerosol sprays, manufacturer’s recommended oil, or multipurpose Teflon grease as processing materials.

How to replace a fork on a bicycle?

It is not recommended for an untrained and inexperienced user to carry out: if it is possible to cope with simple care, then it is better to leave such a procedure to a qualified specialist. As a last resort, carry out the replacement under the supervision of the master, following his recommendations.

The main reasons for disassembling a bicycle fork are:

Modern front suspension forks come in many different types. Inexpensive ones include spring-elastomeric ones, which are mainly used on budget mountain bikes: ardis, formula, stealth (stels), forward, cronus, etc.

Taking care of your fork is the key to its health

Bicycle fork should be lubricated once a season, but with heavy use this procedure may be necessary more often. The process of lubricating a spring-elastomer fork is extremely simple: oil is poured with a syringe under the boot, then the fork is developed, and the remaining lubricant is removed with a soft cloth. Teflon grease is best applied to the feet near the oil seals (aerosol grease is increasingly being used).

Among the best lubricants, masters call silicone and transparent greases.

It is equally important to keep the forks clean: be sure to wipe the legs of the forks near the boots after each bike ride to avoid dirt getting into the oil and impairing the proper functioning of the bike.

Adjusting the bike fork begins with setting the sag, then rebound (if its adjustment is provided), under which the low-speed and high-speed compression will be adjusted. Experts note that the adjustment should be carried out in stages: you made one change. you checked the progress of the bike with a walk, only then change the next parameter. If you do not adhere to this recommendation, then the owner risks missing out on the difference in travel and lubricating the effect of the fork adjustment.

TIP! You need to start the fork adjustment process from the neutral position: half set rebound, compression arrows unscrewed completely counterclockwise.

How to assemble a bike fork?

The assembly of the plug takes place in the reverse order of the parsing process and it is impractical to describe it additionally. The main thing is to carefully follow the order of the described procedures.

How to put the plug

The plug is assembled in the same way as the parsing process was performed, but in the reverse order. The main thing is to carefully double-check each element so that the installation of the components does not turn out to be erroneous.

Do not worry about the excessive amount of oil released during the first driving time. This is normal as excess grease will escape through the cuffs of your pants. As soon as the extra material comes out, the selection process stops immediately. Any residual lubricant should be washed off after each use of the bike.

Useful to pay attention

The most popular and cheapest shock absorber is spring-elastomeric. This shock absorber is very simple in design: a polymer rod is inserted inside the steel spring, which dampens vibrations.

The second type is oil-spring, more modern and reliable. Due to its relative cheapness and simplicity of design, it has become one of the most common in cycling.

And the third type is oil-air. It uses a compressed air cylinder instead of a spring. Due to the complexity of the design, it is better to repair them in specialized workshops, where they know exactly how to lubricate shock absorbers on a bicycle.

Disassembling a bicycle fork is easy. To do this, it is enough to follow the instructions provided. The purpose of this enterprise is troubleshooting, cleaning, lubrication and oil change.

Before proceeding directly to the dismantling of the bike, you need to prepare items that will be useful in the process of repair work:

  • you should wear repair clothes (old or unnecessary equipment), which in the process of performing work can get pretty dirty;
  • it is advisable to cover the surface with various rags or newspapers so as not to contaminate the floor of the room with oil;
  • you need to collect around you all the necessary tools (hexagons, screwdrivers, etc.);
  • need to purchase oil.

Rear shock absorber creaks on a bike: what to do?

This complex detail includes a lot of different elements. The first thing to do when extraneous noise appears is to disassemble the unit and check for grease.

The majority of the shock absorbers have settings that can be adjusted correctly to better control steering and speed while driving. In addition, wear on the assembly is reduced. Consider the sequence and features of this operation.

Lubrication of shock absorbers

A poorly oiled and misaligned mechanism can not only make an unpleasant sound, but can also make it difficult to control the bike, spoiling all the enjoyment of sports. The ideal option is to externally clean the bike fork after every ride, and at least once a season to lubricate the internal parts of the mechanism. The easiest way is to take the bike to a workshop, whose master knows exactly what to do, but experienced cyclists can try it themselves.

Springs and Elastomer Springs can be lubricated without disassembling the bike fork. For this, the grease is drawn into a syringe and poured under the boot. After that, the bike should be rocked and excess oil removed with a napkin. But! This is a quick, hiking option used when the bike cannot be disassembled even partially. According to the rules, you should first unscrew the mounting bolts from the bottom, then unscrew the Preload bolt, get the elastomer and the spring, unscrew the mounting bolts and remove the pants, that is, the part of the bicycle fork to which the wheel is attached. This is where the most dirt is found and it is this part that most often needs repairs. Anthers are taken from the last part (they can be easily picked up with a screwdriver).

Maintenance of the oil spring design is also simple. If the open oil bath method is used, then the oil is simply drained and the parts cleaned. This system is perhaps the easiest to maintain, and inspection and minor repairs can be performed even at home. Things are a little more complicated with a closed oil bath. The oil in this design is in the capsule and changes with the entire capsule. In contrast to the first option, a closed oil bath often requires more maintenance.

The most whimsical service is considered to be an oil-air shock absorber. To clean and lubricate it, you must:

Motorists have a saying: The car loves affection, cleanliness and lubrication. The same can be said for a bicycle, although it requires much less maintenance. If you know how to lubricate shock absorbers on a bicycle, then this procedure will not seem long or laborious at all, and the iron horse runs without repair for more than one season.
