How to disassemble a sports bike fork

If there is a play in the front fork of the bicycle ➔ elimination, repair

Today we’re going to talk about how to eliminate play in a sports bike suspension fork. This scheme is suitable for all brands of popular and not so popular bicycle suspension forks such as RST (OMEGA, Blaze, GILA, Capa), SUNTOUR (XCR, XCM, XCT), Rock Shox, zoom and others. Inexpensive forks are arranged, as a rule, in a similar design, so the instructions for bulkhead and elimination of backlash can be applied to almost any model. Read what bicycle forks are, their types and types.

Prevention and elimination.

For convenience, I would recommend removing the fork completely, but some do it on bicycles as well. It should not be difficult for you to remove the fork from the bike, unscrew a couple of bolts, remove the handlebar and, if necessary, brakes or a cable.

Removing the fork legs.

We unscrew the nuts or hexagons from the bottom, with a 10 wrench, then we will see the threaded ends from which we unscrewed the nuts, in order for the legs to come off, most likely it will not be necessary to hit them hard with a hammer. In order not to knock off the thread, it is necessary to screw the nuts a little again and knock out the pants with light blows.

Now you need to remove the oil seals that prevent dirt from entering the fork. To do this, you need a small screwdriver, pick and remove them.

Next, you need to remove those parts that directly break the fork and create a loofah. bosses or they are also called guides. The guides have latches, so we pull them out by turning them a little, to release the latch of the retainer from the groove in the pants.

The reason or why the backlash of the mountain bike front fork comes from?

In the design of a bicycle fork, namely in the legs, a pair of rails are installed, which are made of plastic, they are called bosses. Due to their wear and tear, this phenomenon occurs.

How to determine if there is a backlash?

Everything is very simple, just press the front brake and move the bike back and forth, if there is a play, then you will definitely feel it. For inexpensive forks, backlash is not uncommon, it manifests itself very quickly. Minimum backlash is allowed. Over time, the backlash will increase and it is worth thinking about the bulkhead and finalizing the fork.

Working with guides.

Let’s move on to the most important thing. It is necessary to wrap tape or electrical tape on the guides. How many turns you need to wind depends on the wear. First, try making a couple of loops and inserting the guides into your pants. Where the latches are not wound, or cut out where necessary. If they got up tight, then maybe that’s enough. Remember how easily they were extracted from you. Having done this manipulation with both bashings, you can figure out putting your pants on your forks and shake them. If there is backlash again, then remove it again and add a couple more with a skein on the plastic guides and reassemble until we achieve the desired effect.

Before assembling the fork, it is imperative to clean it of old dirt and grease, rinse the oil seals (anthers) and other parts. It is also advisable to lubricate the rails, fork legs.

In principle, in such a simple way, you can eliminate the play on the bicycle fork, it does not take much time. How long such a repair will last depends on how much and on what roads you ride. From time to time, with the appearance of a backlash again, you will already know how to eliminate it, at the same time you will go over and anoint the plug, which will give, though not for long, but a positive effect. It’s still cheaper than buying a new fork if you are already buying a good quality high-end fork. But even with such forks, you will not bypass MOT, but the resource will be an order of magnitude higher.

How to remove the plug

Let’s take a look at the step-by-step process of disassembling a bicycle fork:

  • First you need to unscrew all the parts that are attached to the plug. These elements can be brake calipers or disc brake lines. V-brakes are also removable.
  • The bolts that fix the stem on the handlebar tube are unscrewed, after which it is necessary to unscrew the anchor bolt of the bicycle fork.
  • Then you need to carefully remove the steering wheel. You should be extremely careful not to damage the hose lines.
  • In the next step, the spacer rings and the guide sleeve are removed. In order to perform this procedure, carefully pry the sleeve in the area of ​​the cut using a flat screwdriver. Further, the upper rolling ring and the upper bearing are detached.
  • The steering tube can now be removed. Then you need to get the bearing, rolling ring, and also detach the front wheel of the bicycle. To do this, unscrew the fixing bolts. The result is an unscrewed bicycle fork.


Air bike forks are versatile designs that stand out for their unique functionality. The damper and spring in such forks is the competence of the air, due to which a small mass of the structure is formed. But such elements are not ideal, since air etching often occurs in frosty weather. Also, there are no special settings, and air is pumped into the system using a high pressure pump.

Experts advise keeping a close eye on your vehicle so that you don’t end up spending a lot of money fixing your bike. Continuous fork maintenance helps prevent unwanted damage. In this case, the parts will not break (or will, but in the most rare cases) and they will not need to be replaced with new elements.

Since some types of forks are not very popular, finding parts for the construction will be very problematic. An example of a bike with an air front fork is the Stels Navigator 360. A video review of the bike can be seen below.


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.

[attention type = yellow] Important! Experts advise to lubricate the bike pick as often as possible so that the vehicle will serve for many years in good condition. [/ Attention]

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.

How to repair a bicycle front fork

A bicycle fork serves an important function in maintaining the functionality of your bike. First, it connects the front wheel of the bike to the frame and handlebars. Secondly, the fork is a shock-absorbing device that smooths out vibrations and reduces the load on a person’s hands.

Thus, this element may lose its characteristics during operation, as a result of which it may be necessary to repair the front fork of the bicycle. In this article, we will look at the procedure for bringing a bicycle fork into service.


In addition to suspension forks, there are many more options that have certain advantages. In this section, we note the oil forks for bicycles, which are of two types. oil-air and oil-spring. The table below highlights the features of both of the above types of bicycle forks.

Plug Type Features
Oil-air In the ratings, a bike with such a fork is considered one of the best. Air in this case acts as a spring. Oil, in turn, is a shock absorber. After compression, the air is gradually restored, due to which the oil flows from one unit to another. These forks have a lot of different settings, but, most importantly, they are optimal in terms of weight.
Oil-spring Unlike oil-air forks, it is the spring that plays the role of the spring component in such forks. The weight of this design is significantly greater than the weight of other types of forks. The main advantage is the excellent cushioning effect. Also in the oil-spring fork, processes take place that ensure a smooth ride of the bike.

Let’s note the peculiarities of prevention and care of a bicycle fork. Experienced cyclists are able to fix any problem on their own if they show interest in their vehicle and understand its details. Finding the cause of the breakdown for such people is quite simple, as well as fixing the breakdown.

[attention type = red] Important! Inexperienced cyclists are advised to seek expert advice so as not to permanently break the bike. [/ Attention]

All cyclists, without exception, can carry out prophylaxis. To do this, you need to check:

  • Serviceability of the end of the front fork, which is attached to the frame (rear triangle) of the bicycle (dropout).
  • Check for various injuries to the legs.
  • Check bike fork boot for damage or leaks.
  • Analyze air chamber pressure readings.
  • Inspect the condition of fasteners.

over, it is necessary to regularly arrange the cleaning of the master keys, as well as to change the oil. For this procedure, you can use both specialized bicycle oils and liquid oils for cars or sewing machines. When choosing a lubricant, you should pay attention to its resistance to various weather conditions.


In many bicycles, the front shock absorber is built into the structure. This fork is called a depreciation fork. Bikes with a similar component are used for movement in mountainous terrain, where there are practically no flat roads. Thanks to the functionality of the fork, unevenness is smoothed out, which allows you not to experience discomfort when driving.

Unlike other types, suspension forks require constant monitoring, periodic cleaning and gentle maintenance. over, inspection and depreciation maintenance must be carried out even when the bike is in a static position for a long time.

Let’s take a look at the two features that make a suspension fork different in the table below.

Item Description
Trousers Tubular glasses (2 pieces) are combined into a piece called a gorilla. The legs of the construction fit into the pants. Amortization occurs in the legs.
Plugs The pipes of the legs are closed from above. In bicycles that are quite expensive, suspension stiffness adjusters are installed, as well as blocking.

Damping forks do not differ in material of manufacture from their other counterparts. For production, various combinations of materials are often used, since the fork includes individual elements that can be made in different ways. The best option, according to experts, in this case is the use of carbon parts. The legs of the suspension forks are often made of aluminum alloys.

  • Regular. Simple forks on hilly bikes (mountain bikes).
  • Double-crown. Bikes with such forks are fitted with two crowns, which adds to the advantage during downhill runs.
  • Inverted. A mirror image of a normal fork. Such bicycles are subject to heavy loads, therefore they are well used for performing various jumping elements.
  • One-legged. It is rarely used in everyday life. Installing a rim brake on such a fork is impossible, but the main advantage is the ability to replace the chamber without dismantling the wheel.

How To Remove Front Forks on a Motorcycle from

Disassemble the fork before proceeding with the cleaning and repair procedure. Parsing takes place after removing it from the bike. The withdrawal process will be discussed in paragraph 3.

Consider the stages of parsing a suspension fork:

  • The fastening bolts are being loosened.
  • The pants are removed from the legs and, if necessary, the oil seals are removed.
  • Removes old grease, both from the surface of the fork and inside the pants.
  • The travel stops and their stops are removed. To do this, they are pulled off the rods.
  • The adjustments on the legs of the fork are unscrewed with a key.
  • Again, the surface of the fork is cleaned of old lubricant.

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.

[attention type = yellow] Important! When the structure is already installed on the bike, you should examine the absence of play in the handlebar tube in the frame glass. If backlashes are found, then their elimination is necessary before the trip. [/ Attention]

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.

How to disassemble a bicycle fork?

A bicycle fork is a device that connects the frame to the front wheel. Often it fails, as a result of which the wheel stops rotating or produces it, but with a slowdown. In such situations, you need to disassemble the plug.

Disassembling a bicycle fork may be necessary in many cases. It is not always worth contacting specialists for this. It is always possible to do this work yourself. The main thing is to do it consistently, then there will be no problems.

Before disassembling the bike fork, you need to set it on a flat place covered with paper and oilcloth, and lean it against the wall. It’s great if you can fix it with something, for example, with props in the form of cobblestones or wooden bars. Then you need to pick up a wrench that will help to grip the bolt head located in the middle of the steering wheel. She is responsible for fixing the steering wheel to the fork.

To disassemble the bike, you need to unscrew this bolt. It should be borne in mind that it is long enough and is additionally fixed inside the fork tube with a cone nut. Therefore, you will have to make sufficient efforts to remove it with a wrench. There is no need to rush to quit this business if nothing worked the first time. Efforts should be made again, sooner or later it will come out of the hole. Having completely unscrewed the bolt, you need to loosen the steering wheel and remove it from the fork tube. Next, you need to go to the frame cylinder. It is necessary to remove the plug tube from it. To do this, you need to arm yourself with a gas wrench and unscrew the overhead nut located on the top of the cylinder. If such a manipulation fails, then you need to use another tool at hand. It can be a special key that comes with many bicycles. It should be used when doing repetitive work.

This does not complete the removal of the bicycle fork. After the nut is unscrewed, you will need to remove the bearing. As a rule, when the fork is removed, it collapses. Therefore, do not be surprised if no balls are present in the mountings. Having removed the bearing and all its elements, you need to try to remove the tube from the plug as carefully as possible. Having done this, it is not difficult to see another bearing. He also needs to be removed, so this must be done. Then such a detail will need to be put aside. Then you need to take a screwdriver and unscrew the bolt that holds the fender to the wheel. It is located on the top of the frame cylinder on almost all bicycle models.

After removing it, you need to immediately unscrew all the bolts that hold the wire holder. Usually they come in quantities of at least 5 pieces. However, having unscrewed them, it is not always possible to disconnect the wing after that. The point here is that some bicycle manufacturers also fix it on hidden mounts. They can be seen when viewed under the wing. Accordingly, if any are present, then they must be removed. After removing the fender from your bike, you need to take care to loosen the nuts that hold the fork and wheel. To do this, you can use conventional wrenches of a suitable diameter. Having made such manipulations, you will notice how the fork is completely released. Therefore, it remains only to take it out and put it aside.

As you can see, it is not difficult to disassemble a bicycle fork. Having done this, do not forget that it is necessary to change the bearings, and then lubricate the parts with lithol. Collect your bike transport in reverse order. It is important in the course of this to ensure that all the details are fixed correctly, and that there are no unnecessary elements left after such work. If this is noticed, you will need to disassemble and reassemble.

Dismantling and replacing a bicycle suspension fork

Not only the long service life of the bicycle, but also the safety of the cyclist itself depends on the proper condition of all components and mechanisms. Today’s publication will be devoted to one of the important details. a bicycle fork, about the methods and methods of its repair and installation.

Bicycle fork maintenance and repair

As you may have noticed, removing, disassembling and lubricating a mountain or city bike suspension fork at home is not that difficult. The main thing is to treat this process responsibly and do everything consistently. The better you take care of your iron horse, the longer it will delight you with its trouble-free work.

How to remove, disassemble and lubricate a bicycle fork

If you do not know how to remove and disassemble a mountain bike suspension fork for maintenance, repair or replacement, then this article will help you find out what you need for this, and how to do it at home. Also, such questions will be considered here: how and how to lubricate the front fork, the frequency of maintenance and other tips on this topic. All this will be presented in the form of detailed instructions with pictures for each action, as well as a video for disassembling a bicycle suspension fork. In this article, we will analyze the RST GILA 100 mm spring-elastomer fork with disc brake mountings.

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.

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.

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.

Removing the fork from a bike?

To remove the fork from the bike for subsequent maintenance or complete replacement, it is necessary to turn the bike upside down, release the brake (if it is a rim brake) and remove the front wheel. At the second stage, the steering wheel with the stem is removed, then the steering tube.

After that, we remove the plug, it is extremely important not to lose the balls from the bearings. Then the support tapered ring is removed from the fork stem (usually using a sharp measure, gently squeezing it from all sides). Then we have a plug ready for service.

Individual users are advised to sort out even new, just purchased forks, explaining this by the need for individual debugging of the element.

How to disassemble a bicycle fork (using the example of a spring-electric fork) read below:

    it is necessary to unscrew the lower mounting bolts using hexagons;

Preload spring force adjusting bolt.

This completes the fork disassembly process and begins the process of caring for the parts received: a thorough inspection of the elements for damage, cracks and other things is necessary, thoroughly rinse with kerosene and lubricate the elements that need it. It is important to lubricate the springs with heavy grease for best fork performance.

Fork maintenance

In addition to a routine inspection, the fork also requires regular maintenance, namely:

  • every 100-150 km of the distance traveled, it is necessary to clean and lubricate the feet on the oil seals;
  • every 500-1000 km. disassembly and full lubrication of oil seals;
  • every 4000-5000 km or at least once a year an oil change is made (applies to oil plugs)

In general, a bicycle fork should be lubricated at least once a season, however, if you are actively using your bike, this procedure is recommended to be done more often. If we consider a spring-elastomer fork as an example, the lubrication process will look like this:

  • Using a syringe, oil is poured under the boot.
  • For the lubricant to be evenly distributed, the fork must be designed.
  • Remaining oil must be removed with a soft cloth.

According to experts, it is better to use silicone and transparent greases as a lubricant.

In addition to lubrication, maintaining a bicycle fork also includes keeping the devices clean. To exclude the possibility of dirt getting into the oil and malfunctioning of the bike after each walk, you need to wipe the legs of the forks near the anthers.

Also, the bike fork can be adjusted by sag or rebound (if available). However, as experts note, this procedure should be performed in stages: after changing each parameter, you should check the progress of the bike. Otherwise, the rider may miss out on the difference in travel, and the effect of fork adjustment will be blurred. It is worth noting that the masters advise to start adjusting this device from the neutral position, in which the rebound should be set halfway, and the compression arrows are unscrewed completely counterclockwise.

Fork repair

Work on changing the oil, foot oil seals, sealing parts, as well as on eliminating a malfunction of one of the components is accompanied by a complete or partial disassembly of the bicycle fork.

Fork routine inspection

Often, it is the prophylactic inspection of the fork that makes it possible to timely identify minor deviations from the norm in the operation of the device, and, accordingly, prevent a more serious breakdown. Generally, a visual inspection of the fork includes checking:

  • dropout states;
  • fork legs for dents, scuffs and other marks;
  • oil seals (anthers) for mechanical damage and oil leaks from under them;
  • pressure in air chambers;
  • presence and condition of lateral leg play in pants;
  • the condition of the fastening bolts under the forks and the adjustment knobs.

Most often, bicycles are equipped with a front suspension fork, thanks to which it is much easier for cyclists to overcome road bumps even at high speeds, while the load on the palms and hands during riding is minimal. By minimizing vibration, a well-matched and aligned fork extends the life of other bike components such as the frame and steering bearings.

The lifespan of the plug itself can be extended several times through proper care and regular maintenance.

Consider the procedure for removing a fork from a bicycle.

First you need to turn the bike with the wheels up, and after releasing the brake (in the case of a rim brake), remove the front wheel. After that, you can remove the stem with the stem and the head tube.

Then we remove directly the plug itself. It is important to ensure that the balls are not lost from the bearings when removing the fork. Any sharp object can be used to remove the tapered support ring from the fork stem. After that, you can start repairing or servicing the plug.

Next, consider the procedure for disassembling the fork (a spring-electric fork will act as an example):

  • The lower fixing bolts are unscrewed using hexagons.
  • The preload spring force adjustment bolt is unscrewed (it is important to remember the bolt stroke).
  • An elastomer is obtained, which is responsible for the function of limiting the travel of the spring (sometimes, if necessary, you can change the size of the elastomer by cutting).
  • The bolts are unscrewed and the pants are taken out. In this case, you need to monitor what flows out of there (dirt, water, oil).
  • Anthers are taken out of the pants with a screwdriver, as well as bosses, which for this need to be rotated around their axis.

Further, all components are checked for cracks or other damage and washed with kerosene. Items requiring lubrication are treated with an appropriate material. It is worth noting that it is better to lubricate the spring with a thick grease, which will increase the efficiency of the bicycle fork.

Some cyclists even go through only purchased forks, trying to individually debug the device.

The fork assembly process is performed in the reverse order of the parsing process, so we will not describe it.

It is better to entrust the procedure for replacing the fork on a bicycle to a qualified specialist or perform it under the supervision and according to the recommendations of the master.

As practice shows, owners can be divided into two types:

  • Those who ride a bike until the last breath of transport, and only when all systems completely fail, think about repairing the device.
  • Those who carefully monitor the condition of the bike, follow the rules for caring for it and prevent any breakdowns.

It is no secret that the approach of the first type of owners ultimately costs much more, because often it is necessary to replace the components of the bicycle that are not recoverable. In addition, there are times when the bike can no longer be saved.

In principle, experienced users are quite capable of handling fork repairs on their own, because over time, every cyclist who shows an interest in his transport will remember the name and functions of the parts, and it is no longer difficult for him to find the cause of the problem. If there is no relevant experience and skills in repairing a bicycle, then you should not experiment and it is better to contact competent specialists. In addition, ignorance of the design features of the fork itself can lead to difficulties in eliminating its breakage.
