Signs of dysfunction
In order for the fork to work for a long time, the bicycle owner must from time to time service this important part.
The necessary preventive work includes:
- applying lubricant;
- replacement of oil seals;
- on the alignment of the steering tube;
- replacement of bearings.
Particular importance is attached to lubrication. It provides superior cushioning and reduced component wear. It is performed every 400 km. If the bike is not used so intensively, then once a season this procedure must still be performed. Separately, oil seals are lubricated after 700 km of run.
These are very average recommendations. It all depends on how you use your bike. If he is daily taken out on difficult routes, then lubrication should be performed more often.
The service life of bicycle components is reduced by poor-quality surface or embossed track. It wears out especially quickly when driving on sand and abrasive materials. Experienced cyclists can identify fork dysfunction by hearing characteristic sounds. The need to debug or replace worn-out elements is determined by a knock or squeak during riding.
In addition, typical wear symptoms are:
- tight adjustability;
- difficult steering wheel;
Finally, as a result of daily visual inspection, visible defects can be found. If you find cracks in your legs or pants, urgently take action.
A fork is a multicomponent element. Attached to it are the speed sensor, brake caliper, hydraulic line, fender, V-brake.
In order to remove it, you must sequentially perform the following steps:
- remove the bolts that hold the stem on the rudder tube;
- dismantle the anchor bolt;
- dismantle the steering wheel with a stem (this must be done with the utmost care, since there is a danger of damaging the hydraulic line);
- dismantle the spacer rings;
- remove the guide sleeve;
- remove the lower part of the handlebar from the retaining glass;
- remove the bearing;
- carefully remove the rolling ring.
After that, the eccentric is loosened and the wheel itself is removed.
The bike owner must have a complete set of screwdrivers. For example, to remove a guide sleeve, you need the most compact of them. Only with it can you pry the sleeve in the cutting area.
It is recommended to lay out all the dismantled elements in sequence. as they were removed. A tried and tested trick is to photograph every stage of the work. This will allow the reverse assembly to be carried out without error.
How and how to lubricate a bicycle fork?
Every part of the bike has its own functional meaning. The fork is designed to smooth out shocks and minimize stress on the arms. By fulfilling the amortization task, it extends the useful life of the frame. The fork is a fairly strong part, but it needs periodic preventive measures. This article explains how to lubricate a bicycle front fork.
There is still a long way to go before the start of the lubrication procedure. It is performed at the very end, when the removed and cleaned parts are inspected for suitability and defects.
In the meantime, it is necessary to free all the dismantled components from the stratification. Used grease tends to compress or shrink. This stage will take effort. Disassembly begins only after complete cleaning.
- Removing bolts.
- Dismantling of pants. The internal faces are checked immediately. They must also be freed from used grease.
- Removing the oil seals.
- Removing the bottom stops. This action must be performed carefully, without exerting physical effort.
- Dismantling stops.
- Gradual weakening of the legs. To do this, you need a special key.
- Removing 2 rods.
- Removing the spring.

The removed parts are also freed from old grease. To do this, you need to stock up on a large amount of rags and a plastic scraper in advance. It is undesirable to use metal objects for cleaning.
Finally, the fork is fully prepared for the lubrication procedure.
To answer the question of how to lubricate a mountain bike fork, you need to familiarize yourself with all the proposals of specialists. This will make it possible to choose the best option.

All types of bicycle lubricants are classified as follows:
- Thick. Benefit: Works well at high and low temperatures. Disadvantages: Able to attract dust. These include graphite compounds, as well as technical petroleum jelly.
- Liquid. Advantage: ease of application. They work well at high and low temperatures. Disadvantages: a change in viscosity with a sharp temperature drop, the ability to drip. These include industrial oil.
- Two-component. The composition contains a thick oil, as well as a solvent. Ideal for machining prefabricated mechanisms. These include wax and Teflon products. Silicone two-component lubricants are recommended for use on e-bikes. They act delicately, and the excess is easily removed.
So, the procedure begins by applying the product to the spring. The grease should literally be rammed between the rings. There is no need to worry about surplus formation. They seep through the packing holes. It is advisable to apply another layer to all grooves of the cuffs.
Elements in motion (rubbing) require a particularly thin layer. When the procedure is over, the installation of the plug begins in the reverse order.
Bicycle owners often ask how to lubricate a bike suspension fork without disassembling it? Industrial oil can be used as it has a light consistency. However, this will be a partial lubrication. It will only be possible to lubricate the legs of the bike fork.
The oil is applied drip at the point where the legs enter the pants. Then several back and forth movements are performed to push the oil further. Surplus funds are removed.
So, the procedure can be carried out independently if you have high-quality lubricant and a set of tools.
How to lubricate the front fork of a bicycle? General issues
Nevertheless, with all the variety of bicycle suspension forks, there are a number of principles and points common to all of them that relate to their maintenance, including lubrication.
How to lubricate a bicycle fork?
In technology in general, and in bicycle technology in particular, only mutually moving parts, more precisely, their rubbing pairs, are subject to lubrication. For this reason, owners of bicycles with rigid rigid forks can safely ignore this information, since they have no moving and rubbing elements by default. It may be relevant only for owners of soft shock-absorbed bicycle suspensions of the front (and also rear) wheels, who have certain ambiguities regarding the organization of lubrication of shock absorbers.
So, the happy owner of a bike with a soft amovilka felt something wrong in its work, or simply decided to lubricate it in advance as a preventive measure. If he is still an inexperienced bicycle kettle, then two key questions arise in front of him in full growth:
- how to lubricate a bicycle fork?
- how to lubricate the bike fork?
Unfortunately, these key questions cannot be answered straight away. Why? Because there are many varieties of bicycle shock absorber designs, plus their numerous structural nuances are added by almost each of their manufacturers. And each of these designs has its own characteristics in terms of the order and technique of lubrication of the bicycle suspension fork.
How to lubricate a bicycle fork?
Shock absorbers for wheeled vehicles, including bicycles, are mechanisms made with sufficiently high accuracy tolerances. So the question is how to lubricate the fork of a bicycle? requires the most careful attention and understanding of technical nuances.
Strictly in relation to amovilka spring-elastomer design (lubricated), you should use only special bicycle lubricants of two-component composition: Teflon or silicone. They are film-forming teflons and silicones diluted with an organic solvent (Teflon) or a diluent (dispersion silicone), which, by their state of aggregation, are conditionally solid amorphous substances. Their characteristic feature is that after application they form a non-adhesive (non-sticky) film with a low coefficient of friction, on which road dust suspended in the air is deposited much worse than on a fatty organic lubricant.
Yes, indeed, the price of special teflon and silicone greases bites. Therefore, many cyclists are tempted to lubricate their front suspension forks with all-purpose, one-piece lubricants, which are more affordable. Most often, liquid oils (industrial, any motor), or solid lubricants (Litol-24, graphite) are used for this purpose.
But, nevertheless, this should not be done, because a thin greasy (sticky) film of such oils and greases during the operation of the shock absorber is inevitably carried out on the surface of the rods of the inner pipes outside the sealing gland, and then it is also brought into the glass along with the adhered to her with road dust. Very soon, an abrasive dust-oil mixture forms inside such a shock absorber, which quickly eats up precisely fitted rubbing pairs of its mechanism, and incapacitates it.
How to disassemble a bicycle fork with a shock absorber
The front shock absorber is fully responsible for how comfortable and comfortable your bike is controlled, whether, for example, there are any vibrations that give off in the wrist.
The main purpose of dismantling a bicycle fork is to clean, lubricate and refill with fresh oil. Due to the regular carrying out of such procedures, you can significantly increase the life of the part.
- Choose clothes that you won’t mind getting dirty, prepare old rags, cover your work surface with newspapers, working with oil is a dirty business;
- Prepare the necessary tools;
- Buy replacement oil.
How to disassemble?
Now we will consider the process of parsing the fork itself, in our case. the spring.
- It is necessary to unscrew the lower mounting bolts and unscrew the bolt that controls the spring;
- Remove the elastomer that limits the spring travel;
- Unscrew the bolts and remove the pants to pull out the oil seals and drain the oil.
This concludes the process of disassembling a bicycle fork. It is important to carefully examine all the elements that appeared in front of you for cracks and deformations, lubricate the springs, and then carefully reassemble in the reverse order. Be careful on your first ride and gradually develop the fork.
As you can see, disassembling the plug is not the most difficult job, but carrying it out can extend its service life for some time. Bicycle spring fork repair, how to disassemble and lubricate. there is a lot of information about this on professional forums on the network.
When we say a bicycle fork, we often think of a front shock. But modern bike models are also equipped with a rear shock absorber, which also needs care.
Periodically, she needs to carry out repair and preventive measures: applying new grease, replacing bearings, oil seals or other worn elements, aligning the steering tube and performing similar work.
Before lubricating a suspension fork on a bicycle or replacing worn components, it must first be dismantled and disassembled.
It is recommended to lubricate the oil seals after about 700 km of run, at least every season, and to sort out and lubricate the entire fork with a lubricant compound at intervals of 4000 km.
If the vehicle is operated under conditions of increased exposure to sand and other abrasive materials, its fork will have to be lubricated more often.
They say about the need for prevention or repair of the fork: squeaks, knocking and other suspicious sounds during driving, jamming, uncontrollability, backlash, cranking or difficult movement of the steering wheel, cracks in pants or legs and other similar defects.
