How to untangle a bicycle chain without removing

How and what to clean the bike chain?

The bicycle chain, one might say, is the main knot thanks to which movement is possible in principle. The efficiency, ease and speed of skiing directly depend on its quality and condition. The main parameters of a serviceable chain are its degree of wear, setting and cleanliness.

It is important for both a beginner and an experienced cyclist to understand that mechanisms that are actively in contact with dust, water and dirt should be kept in more or less decent condition. Cleaning your bike chain is a must and inevitable process. It is carried out so that the entire transmission unit serves as long as possible, and the ride is comfortable.

How often do you need to clean and lubricate your bike chain?

In general, how is it determined how dirty the chain has become? You don’t have to go far, just look at it. Lumps of earth on the surface of the links, an abrasive mixture of old oil and sand, smudges. these are all signs that directly indicate that it is time to get down to the bike chain.

The outer side usually brings the state of the chain to clean water. However, this is not always a reliable indicator. For example, prolonged driving on dry dusty roads may not affect its appearance in any way, but from time to time there may be an unpleasant crackle.

The fact is that dirt sticks very well from the inside, in the spaces between the rollers. You can see at once in what state the chain is possible only on ordinary singspeeds. On high-speed models, such dirt cleverly hides among a large number of stars. To have a complete idea of ​​how much the transmission is running, you will have to turn the bike over.

Those who like to ride after rain or in slush (and there are a lot of them) will have to clean the chain almost after every ride. At a minimum, wipe and lubricate. When riding on dry roads, the grease lasts longer, but its useful properties are gradually reduced by sticking dust. The dirt accumulated over time begins to interfere with movement, and affects the stars.

Much depends not only on the conditions, but also on the riding style. A neat and measured ride will definitely outperform aggressive driving in terms of cleaning and lubrication intervals. So cyclists who like to push their two-wheelers to the limit will need to clean the bike chain more often.

On average, under standard conditions, you need to look into the transmission unit 1. 2 times a month. often if desired. You just need to remember that excessive lubrication will quickly contaminate the system.

How to clean a detachable chain

The chain lock is a convenient and practical thing in terms of maintenance, since you do not have to sweat next to the bike looking for dirt. The chain that is detached from the bike is better cleaned than the chain hanging from the frame. Washing options:

  • soak in kerosene;
  • intensive rinsing in a bottle with solvent;
  • manual cleaning and washing with brushes.

The first method removes plaque from the outer surfaces of the links. With lumps stuck between the rollers, a simple soak does little. After it, you need to knock out dirt from the internal cavities using a thin knitting needle or brush.

A more effective way is to rinse the chain in a container. For this you will need:

  • capacious plastic bottle with a wide neck;
  • solvent (kerosene or acetone);
  • detergent (washing paste or dishwashing liquid);
  • small amount of grease.

The dirty chain is put into a bottle, then filled with solvent. Close the lid and shake vigorously for 10 minutes. This is the main cleaning of adhering dirt.

Then, flushing is done in the same way several times. The bottle with the chain is filled with water (in the same amount as the solvent), a little cleaning agent and a few drops of oil. Shake in the resulting solution for 5. 10 minutes. The procedure is repeated several times until the liquid inside the bottle is almost transparent. Carefully remove the chain from the bottle and wipe it dry with a clean cloth.

Moderately effective method. cleaning the chain by hand using coarse and fine brushes. This will also require:

  • cleaning agent;
  • a few clean rags;
  • grease.
  • Straighten the chain carefully.
  • Apply to a large brush and lather.
  • Clean the outer surfaces of the links. We periodically wash the brush in a solvent.
  • Pre-wipe with a cloth.
  • With a fine foamed brush, go over the internal cavities. For deep cleaning, repeat several times, periodically lubricating with a little oil.
  • Wipe the entire chain with a rag dipped in kerosene.
  • Final wipe with a dry cloth.

For a while, it must be left to air dry; in parallel, all the stars should also be washed. Apply lubricant after the chain is already on the bike.

Removing dirt with a chain wash

Can the chain links be cleaned without removing it from the bike? It is inconvenient and ineffective manually. But what about those who do not have a chain lock, but squeeze is not at hand? A chain-washing machine was specially invented for these purposes.

A chain washing machine is a special machine with gears for engaging links and small brushes inside. The cavity is filled with a special solvent included in the kit. When pedaling, all the links pass through the chain wash. Advantages of using:

  • no need to remove the chain from the bike;
  • easy to put on and take off without deforming the links;
  • you can clear the stars with multiple scrolling;
  • absolutely clean hands.

The chain washer can effectively clean all dirt from the transmission much faster than hand washing it on the frame.

The downside that can push you away from buying a new bike cleaning machine is its cost. And below is a helpful video on cleaning and lubricating the chain:

Cleaning and washing your bike chain is one of the primary procedures in bike care. By adhering to simple principles when washing and repeating it periodically, the cyclist will not find himself in a situation where the bike does not want to ride normally at the most inopportune moment.

How to switch speeds on a bike: rules and basic mistakes

All truly modern bicycles are equipped with a large number of speeds, which greatly simplify the riding process. Different gear ratios allow you to change the speed depending on the terrain, road congestion or the banal fatigue of the rider. But for all this to be of practical use, you need to understand how to switch speeds on a bicycle, and do it correctly.

Malfunctions

Breakdowns in the transmission are many times more common than with other components, and sometimes a number of problems can arise during shifting:

  • The chain tries to grab, but jumps back.
  • The rear derailleur on the bike does not respond in any way to the position of the shifter lever.
  • Shift index does not match gear.
  • The chain sags and falls.

All of the above symptoms may indicate a malfunctioning switch or shifter, but in some cases this can be triggered by a simple break in the cable. Damage or resetting of the derailer often leads to incorrect switching. You can correct this in a matter of seconds yourself, even without tools, simply by unscrewing the cable setting on the shifter or near the switch by a few turns. In addition, derailleurs often take over all side impacts and dutifully tolerate your carelessness in speed selection.

Mountain bikes

The really versatile bikes are the cross-country bikes. It is convenient to ride them around the city, and they are not afraid of paving stones, and you can dash off outside the city for pleasure. On KK bicycles, in contrast to city bicycles, slightly more gears are installed. On a budget cross-country bike there are at least 21 gears (3 in front and 7 in the rear), and on advanced models about 30. In everyday life, only the cassette characteristic is often used to indicate the number of speeds. So, a bike with a 3/10 set can be called a 10 speed bike.

Hardtails have a fairly large number of different gear ratios for comfortable riding both in the city and on rough terrain, and due to the absence of shock absorbers at the back, almost all the pedaling energy is directed to accelerating the bike.

On KK, bikes are equipped with either trigger shifters or grips (on very cheap models, usually Chinese or children’s). The former are much more comfortable and hardy, while covering a wider range of gears (7-12), in contrast to grips (8 maximum).

How the switching system works

There are two types of cable on a bicycle: for shifting and for braking. The speed and clarity of the caliper work directly depends on the quality of the first. And the brake cable may not be at all, since in older models of bikes it is reasonably replaced by hydraulic lines.

Of all the manufacturers, Shimano derailleurs are among the most famous and accomplished parts. Only Sram can compete with them. The Japanese pay enough attention to both entry-level groups and professional equipment kits that go well with cool racing frames.

What not to do

For high-quality shifting on transmissions of the low and medium price range, it is recommended not to do the following:

  • Switch speeds under load.
  • Switch multiple speeds at a time.
  • Start in not fully shifted gear.
  • If the chain is pulled under the carriage or bushing, do not try to pull it out by pushing the pedals harder.

Now let’s finally figure out how to switch speeds on a bike in different situations. In addition, we will study some of the features and secrets of switch control, as well as tricks for caring for the transmission.

Planetary systems

In addition to the familiar external switches (in the form of a dangling foot on the rear wheel), there is another fairly common type of gearbox. planetary hubs. The mechanism of operation is such that a system of gears with a set of different gear ratios is located in the housing of the rear hub. This design is very well protected from dirt and moisture, which allows it to work for many years even without special maintenance.

Shimano Inter 3 and most Sram hubs use a clickbox as a derailleur. If you look closely, on the right side of the frame, on the rear wheel axle, you can see a cable line or a plastic box on the nut. this is the clickbox. It controls the gears inside, and itself is controlled by the shifter. The speed switch on the handlebars on a bike with a planetary is visually no different from a grip shift, but at the same time it has a set of other indexes and therefore is not compatible with conventional transmissions.

On some bushings, for example, Sasch S7 and in general all versions of those bushings, to switch it was necessary to act like this:

  • During acceleration / deceleration, stop pedaling.
  • Switch the speed on the shifter.
  • Start pedaling in a new gear.

If you do not stop spinning, then the gear will not change. Shimano Inter and Sturmey Archer do not have this feature.

What speeds to use?

Many novice riders are also interested in which bike speeds should be used more often, and which should not be touched at all. Unfortunately, this question cannot be accurately answered, since all transmissions and people are different. Someone likes fast and aggressive driving, someone more measured, away from mud and extreme, and accordingly, the sets of used speeds will be completely different.

One thing is for sure: in 80% of cases, ordinary users practically do not use the left shifter, but simply put the second gear and eat until the star is erased. Indeed, set 2 / (where is any cassette gear) is very popular, as it contains most of the most used gear ratios, but it is worth using other speeds to extend the life of the transmission.

Opening the lock and squeezing the link axis

It is quite simple to open the lock: use a screwdriver or other object (for example, a knitting needle) to pry on the pincer clamp. The main thing here is not to damage it, or even better. not to lose it, otherwise it will not be possible to fix the chain later. Next, we decouple the entire link. That’s it, you can remove the chain and do whatever you want with it: clean it, throw it away or shorten it. However, we’ll talk about this a little later.

A solid chain can be disconnected only with a special tool. a squeeze. With its help, it will be possible to easily disassemble the link without damage. The procedure is simple, but you shouldn’t rush:

  • First, select the link for disassembly.
  • We insert the chain into the position of pressing out and pressing in the pin (link axis).
  • Use the handle to tighten the screw and take out the axle. Extrusion direction. towards the squeeze screw, that is, towards yourself.

You should not completely extract the pin, since it will not be easy to return it later.

The squeeze will loosen the axle a little, so a different link should be selected when disengaging again.
Pressing the axle into the link is carried out in the opposite order: connect the adjacent links together and press in the pin with the screw.

How to replace a chain on a bicycle?

The chain is the key element of the bike’s transmission assembly. Sequentially passing through the teeth of the drive sprockets, it transmits torque to the rear wheel, thanks to which the bike rides. In the process of movement, the chain mechanism is subjected to dynamic loads, which over time leads to its wear.

On singlespeeds, as a rule, the chain is designed for the entire life of its operation: when moving along the stars, it walks smoothly and straight, without deviations. Chains are more complicated on multi-speed bicycles: there is no right angle between the front and rear sprockets, which is why it is always at an angle relative to the frame. The stresses on the chain mechanism increase several times compared to parallel transmission, which leads to periodic wear. To avoid damage to the entire transmission unit caused by wear of the chain, it must be replaced in time.

Not only do the “speed” chains need to be removed, they are often removed from single-speed bikes for periodic repairs or cleaning. How to remove the chain from the bike and put it back, we will tell you in this article.

Lock and solid chain

The locking chain is equipped with a special clamping device. It is not difficult to unhook and put on it. you just need to disconnect the lock. To find it, we carefully examine the chain on both sides and find a detachable link. In principle, it will not be difficult to find it on a clean chain: a tick is put on top, which fixes the link and does not allow it to move apart. Also, the manufacturer’s inscription is usually embossed on the key link. If you cannot find the lock for a long time, then either the chain is dirty, or it is lockless, or solid.

A bicycle chain without a lock simply cannot be disconnected: all the links on it look the same, however, and are hooked to each other too. This is very inconvenient when cleaning, for example, it is necessary to carry out a “general cleaning” in a solvent. In the case of the keylock, everything is simple. he stole it and put it in kerosene. Solid bike chain, even taken off the stars, will remain hanging on the frame.

In terms of removal, a chain with a lock is, of course, more convenient than its counterpart. However, for some reason, the fastening may loosen: the tick fly off, and the link itself can be disengaged. There are no such weak points on bicycle chains without locks, and if it is torn, then the point is solely in its quality.

Malfunction symptoms

First of all, attention should be paid to chain malfunctions on multi-speed bikes. Traditionally, the travel time is determined by the mileage, but these values ​​are too approximate, because it all depends on the conditions of cycling: road quality, gear selection, speed, load on the pedals and, accordingly, on the chainrings.

The first signs of a bike chain breakdown are inaccurate gear shifting and suspicious sounds (provided the chain has not lost its lubrication). The following method will probably help to determine the malfunction: bend it away from the largest sprocket and see the number of free teeth. If the chain comes loose from three or more teeth, then replacement is required urgently. Two prongs “warn” that wear is just around the corner, but you can still ride.

Using the same method, you can see the weakening of the chain on a single-speed bicycle: bend it away from the chainring and see the number of teeth.

Another way to measure wear is to measure the length:

  • 304.8mm. Optimum Chain Length.
  • 306.5. 307.5. average wear, suitability for repair. You can ride while you can.
  • 308 mm. high degree of wear on both the chain and the sprockets.
  • than 308 mm. damage to the entire transmission.

How to untangle a bike chain

Measuring elongation requires removing the chain completely from the bike.

Elimination of defects

A common form of wear is chain slack when chain length increases from original length. Previously, the critical values ​​of the length of the bicycle chain were considered, at which it cannot be used. Everything is correct, but the chain does not have to be thrown away immediately, but can be repaired. Under prolonged loads, the axles loosen, which causes longitudinal and lateral expansion. It is impossible to eliminate the transverse, but it is quite possible to tinker with the longitudinal.

untangle, bicycle, chain, removing

It is necessary to remove unnecessary links in such a way that the chain calmly, without interference, passes over the large star. With the help of a squeeze, excess links are removed, the axial shafts are completely pulled out of the removed elements. The main thing here is not to make a mistake and not pull out too many links.

If you have to ride with a stretched chain, then in order to avoid its falling off, you can install the so-called chain dampers. parts that prevent the chain from flying off when driving. There are several types of such devices:

  • Roller with two locks.
  • Wide rollers.
  • Frame (or rollerless).

Using pacifiers as protection is fine, but it would be better to consider changing the circuit.

Fitting the chain to the bike

To put the chain on the singlespeed, it is enough to hang it on both stars, press in the pin or click the lock. With high-speed bikes it will be a little more difficult:

  • Fix switches to small stars.
  • With regard to the location of the tensioning rollers, put the chain on the stars.
  • Combine links.
  • Clamp the chain and press in the axle. If the bike chain is with a lock, we do without squeezing.

After the installation is completed, it is necessary to check the course of the chain: rotate the pedals several times. If no sagging or obstruction is observed during twisting, then the chain is of the optimal length and is installed correctly.

Every owner of a two-wheeled horse will be able to cope with the removal and installation of a bicycle chain. An uncomplicated and simple procedure will not take much time, but it will perfectly help on further trips!

How to remove a chain without a lock

Now we will consider step by step how to use the bicycle squeezer correctly:

  • Select the link to be broken. The one from which the assembly of the chain at the factory began is the easiest. If you look closely, it is slightly different from the others. But you can choose absolutely any pin.
  • Have you chosen a link? Place its pin right in front of the release axle.
  • Slowly twist the knob to one side and gradually squeeze out the pin. Make sure that it does not pop out completely, you will not insert it back yourself. Also, do not lose the roller from the link.
  • Open the circuit, remove it, wash and lubricate.

If you have already disassembled the chain with a squeeze, do not break the same link. This will loosen it, and the mount will become fragile. Choose a new link every time.

Now you know how to remove the chain from a bicycle without a lock. As you can see, nothing complicated!

How to remove a chain with a lock

Each link in the chain consists of half-links. external and internal. They are connected by an axis (pin). A roller is put on the pin, which in turn comes into contact with the teeth of the sprockets.

How to remove a chain on a bicycle if it has a factory lock? This can be easily done in two ways.

Is the lock too tightly closed and does not lend itself? Take a thin wire or cable from the brakes, thread it between the links. Pull the edges of the wire sharply in different directions, the links will open and the lock will open.

Connect two loops side by side and they will be intertwined.!

Important points

In addition to conventional devices, there are models with a lock. a special link, which is slightly different in shape from the others, and allows you to open the link with the help of reverse tension without using a squeeze or other tools, the main thing is to put the lock link correctly. It is not recommended to open the links next to the lock, as this will reduce the reliability of the entire mechanism.

It is very important to remember how the chain is connected to the system, cassette and switches before starting the removal. without a little experience in installation and dismantling, it may be difficult to put it back on.

How to change the chain?

There are two types of chains: with a lock and with a pin. The first case is not of particular interest, since such chains are used on children’s bicycles and replacing them is not difficult, for this you only need a screwdriver.

The situation is more interesting with the second type of chains. a chain with a pin. First of all, you need a special tool. chain squeezing. It is highly discouraged to remove such a chain using available tools. The chain extractor is used to connect and connect the links of the bicycle chain. The sequence of actions when working with this tool is as follows:

That’s it, now the chain is disconnected, you can remove it and put a new one. The process of installing a new chain is fundamentally no different from the process of removing it.

How to put a lock on a bicycle chain

How to put a lock on a bicycle chain

A bicycle chain lock is needed to quickly lock and disconnect bicycle links. Externally, it is a quick disconnect link that consists of two plates. Before buying, you need to familiarize yourself with the information that is given on the packaging. in the future it will facilitate the process of installing and removing the device. As a rule, it also contains an indication of how many speeds are acceptable for the application of a particular model.

It happens that the lock is already present in the biker’s arsenal: it was included with the bike and was put on when buying. It will not be difficult to find it. the brand name is always stamped on it. But if there is no device, and you often have to remove the chain links, then installing a bicycle chain lock, the price of which is quite affordable, is really worth it. To begin with, you need to remove half of the link of the bicycle chain to make room for the device. It will be possible to do this correctly with the help of a squeeze. such a tool will allow you to perform an operation without damaging the links.

Removed external elements must be replaced with lock plates. After that, the lock needs to be fixed. For this purpose, the chain belt is stretched until it clicks. The reverse operation can be done by bending it and sliding the hole until it opens. However, not every lock can be moved apart without the use of an appropriate tool and additional efforts. It is important to remember that for safety reasons:

How to determine the degree of chain wear?

After making sure of the need to periodically change the circuit, you should proceed to explaining the process itself. First of all, you should learn how to determine the moment when the chain requires replacement, because it is difficult to systematically monitor the mileage. The most accurate way to determine the degree of wear is to measure the distance from the center of an arbitrary pin (the axis connecting the links) to the center of the twenty-fourth pin after it with a simple ruler. This distance should be 304.8-306.4 mm. If the measured distance exceeds the recommended one, the chain needs to be replaced.

Disadvantages of using

Like any other bike part, the lock has its drawbacks. And the most important, perhaps, is strength. Since it can be disassembled in two, it automatically becomes less reliable than conventional chain links. This raises the risk that the chain is likely to break exactly where it is installed. But do not worry about this, because this happens extremely rarely and after long-term use.

Of course, a chain lock is a very handy thing. With it, you can easily disassemble and assemble the chain so that you can easily remove it from the bike and then install it. If you install a new copy, then it will last much longer and will not be life-threatening. That is, having installed a new one, you can not be afraid that it will burst at the most inopportune moment. Also, do not forget about the sizes that are suitable for this or that option. In some cases, the same spare part may be suitable for different sizes.

Removing the chain from a bike

The need to remove the bicycle chain occurs when it needs to be replaced, washed thoroughly or boiled in grease (in the case of a single-speed chain). Therefore, a small beginner’s guide.

It is possible to remove the chain from the bike only by removing the axle connecting the links (pin). You can squeeze out a pin without a tool, right in the field placing the chain on the edge of a solid object and tapping the axle with a thin knitting needle.

Unfortunately, this method will not allow you to assemble the chain back, because there will be nothing to press in the pin. Therefore, to remove the bicycle chain, you need to have a special tool squeeze, it is best to take a multitool, which includes all the basic bicycle keys, including the squeeze. I’m very pleased with this one.

Place the chain link on the squeeze so that the pin is directly in front of the tool release axis. Then just twist the knob gently and the pin is squeezed out.

The main thing is to stop at the end so that the pin does not pop out completely, otherwise then your vocabulary will not have enough swear words to push it back.

Below is a video showing what I’m talking about (1:05).

In general, ideally, I recommend putting the lock on the chain, this allows you to remove and put the chain on the bike instantly.

When installing the chain on a multi-speed bike, you need to follow the pattern of pulling along the rollers of the rear derailleur, I painted in red in this picture:

Everything is very simple, and there is absolutely no need to go to the bike master because of some minor problem with the transmission.

Friends, let’s not get lost on the Internet! I invite you to receive email notifications about the publication of my new articles, so you will always know that I have written something new. Follow the link please.

What is this part?

These are quick-release links consisting of two plates. Thanks to its design, it becomes much easier to open and close the links of the bike. When purchasing a lock, you should pay attention to what is written on the package. As a rule, it contains the most important information that will help in the further use of the castle. Particular attention must be paid to how many speeds this lock is suitable for. Most likely, more than one indicator will be indicated there, which is beneficial for users.
