How To Tighten The Chain On A Regular Bike

Removing links

Collapsible chains are placed on a regular bicycle without speeds; they have a lock on one of the links. Most modern speed bikes use non-separable chains with all the links riveted equally well. It is not difficult to disassemble a one-piece riveted chain, it is enough just to grind the heads of the pins on one of its links on emery. It is even easier and more accurate to disconnect the rivets using a special tool. squeeze.

It should be noted that pomace is a versatile tool. With its help, you can not only squeeze out the locking pin, but also re-rivet the disassembled chain. Many squeezes have two working grooves: one is needed for pressing the pin out of the roller, and the other for pressing it in. The mounting location farther from the pressure screw is for ripping the chain pins. You can learn more about using such a tool from the following.

Bike Tension Adjustment Without Gears

Correctly tensioned chain on a bike without speeds should be slightly loose by an amount of sag of about 5 mm.

To tighten the chain on a regular speed bike, you need to:

  • Put your transport wheels upside down.
  • Loosen the nuts or eccentrics of the rear wheel.
  • Adjust the correct amount of chain slack, move the wheel along the inclined grooves, which are called Dropouts.

You need to fix the rear wheel only in a position where it is parallel to the carriage shaft.

When the chain is too tight, it becomes very difficult to pedal on the bike, the parts of the chain drive wear out quickly. Whereas the sagging chain can jump off the asterisks, and it will definitely be impossible to go further.

If the wheel is already against the edge of the dropouts, there is nowhere else to move it, and the chain belt is still dangling, then you will need to remove a couple of links.

Adjusting the bike with speeds

The amount of chain tension on a bike with a rear parallelogram derailleur is set entirely by the force of the derailleur spring. But if the chain is too long, then this tensioner will NOT be able to compensate for its sagging, and it will begin to hit the frame. This is especially true for bicycles with a short rear thrower.
Too short chain makes gear shifting difficult. It will become a prerequisite for accelerated wear of transmission parts. This primarily applies to full suspension bicycles.

Very often, when installing a new chain on a high-speed bike, it is necessary to shorten its length, that is, remove several links.

There are two ways to determine how many links to remove:

How To Tighten The Chain On A Regular Bike

  • Place the chain on the largest sprockets at the front and rear. Pull it, retract the rear derailleur to the limit forward. Now it only remains to add two links, and the optimal length will be determined.
  • By throwing the chain from the front to the largest sprocket, and from the back to the smallest. Pull up the chain until the rear derailleur frame is pointing straight down, more precisely, when the derailleur roller pins are in one vertical line.

It will be more correct to adjust the chain length on double suspension, press the rear swingarm to the position when the front sprocket cassette is as far as possible from the rear ratchet. By marking the desired length, extra links can be removed.

How to tension and adjust a bicycle chain

An important element for the bike’s performance is the chain, the life of which depends on timely care. When working, it should not crack and creak. It is normal that in the course of operation it gradually wears out and, as a result, lengthens. When adjusted correctly, the chain should have a slack of 10-12 mm. When pulling with your fingers, it should give in by 10-15 mm, and if this value is greater, then it must be pulled. Note that this is only relevant for bicycles with or without derailleurs, or with planetary gears.

It is also important to adjust the tension when installing a new chain. More importantly, pull it up after the first three runs. A new part stretches very quickly during the first time of operation.

Chain slip

The chain starts to slip when the tension is released due to the extreme tension. And being overstretched, it, in turn, quickly wears out the sprockets. So, putting a new chain on an old ratchet, you can NOT achieve anything. Anyway, slipping on small stars will remain.

If this is not the first time you pull up the old chain, get ready to replace it soon. Remember that you can only remove two links from it once. In the end, you still have to spend money on a new part.

How to adjust the chain on a speedy bike view.

Mountain, road or other type of bicycle, which uses in its mechanism the ability to move tenaciously from star to star, requires a separate method of chain tension. In such a two-wheeled mechanism, there is a permanent fixation. The tensioning procedure is guaranteed by a spring located on the rear derailleur. When the chain starts to sag, your friend’s speed performance deteriorates and a knock is heard. If the chain is overtightened during the repair process, this leads to poor gear shifting and rapid wear of the stars.

At the beginning of the entire repair procedure, it is worth determining the condition of the sagging chain. This can be done in two ways.

We set the speed to the maximum front chainring and the same rear. At the front sprocket, pull the chain in the direction of the front wheel. As soon as the rear derailleur has reached the stop, we calculate the number of extra links. If there are two of them, then everything is normal. The rest of the indicators indicate that it is necessary to make adjustments.

We position the speeds so that the maximum front chainring and the minimum rear chainring are used simultaneously. In this case, the roller, which directs and the one that pulls the rear transfer, must, correlate along the axis and have perpendicularity to the surface of the earth.

The pull-up process consists in removing the links, which turned out to be redundant. We will consider how to do this in a separate paragraph.

When adjusting a speed bike, you can use a separate tool. the chain tensioner. Its main function is to manage rigidity and save its owner from unnecessary problems with the repair of the problem area.

The mechanical version of the tensioner is tenaciously mounted next to the rear derailleur. The uncomplicated design of such a device Not only clearly fixes the chain, but also serves as protection against unforeseen collapse when pulled.

The installation of the tensioner implies the simultaneous alignment of the device and the switch. The chain will run like clockwork: smooth and precise. But still, such a mechanism is not a panacea for the described problem. Sooner or later, you will have to carry out the process of removing the tensioner and adjust the chain by removing the links. Due to its physical properties, the chain will stretch over time, especially on a high-speed bike. But from the point of view of practicality, the acquisition of a tensioner is necessary in order not to get into a difficult situation while traveling.

It is also important to adjust the tension when installing a new chain. Even more important, after the first three races, pull it up. A new part stretches very quickly during the first time of operation.

How to properly tension the chain on a bike

Friends need to be loved. Even if they are two-wheeled. Such a relationship involves skilled caring for your friend. The chain is tensioned in the name of its safety and the life of the bike. Let’s analyze the question of how to tighten the bicycle chain correctly, quickly and efficiently.

Slippage is a result of a transmission defect.

Part slippage occurs when the tension is weak. And the weakness itself is a consequence of physical stretching. This, in turn, according to the domino principle, leads to increased wear of the stars.

Therefore, if you installed a new chain or tightened the old one, you may not get the result. In this case, the stars also require replacement. Metal that has been worn out cannot be restored.

If you have already had to adjust the chain by removing the links more than once, you need to think about purchasing a new caterpillar. In the end it’s a matter of your safety.

How to remove excess bike chain links?

It is necessary to shorten the mechanism when there is sagging, high loads, if the mechanism is used for a long time, or when changing sprockets.

How to shorten the chain correctly:

  • The chain is thrown onto large stars in front and behind.
  • One link breaks.
  • The caliper must be in a horizontal position, for this, the links should be tightened as much as possible.
  • The last step is to remove or add extra links.

Removing links

Collapsible chains are placed on an ordinary bicycle without speeds; they have a lock on one of the links. Most modern speed bikes use non-separable chains with all the links riveted equally well. It is not difficult to disassemble a one-piece riveted chain, it is enough just to grind the heads of the pins on one of its links on emery. It is even easier and more accurate to disconnect the rivets using a special tool. squeeze.

It should be noted that pomace is a versatile tool. With its help, you can not only squeeze out the locking pin, but also re-rivet the disassembled chain. Many squeezes have two working grooves: one is needed for pressing the pin out of the roller, and the other for pressing. A mounting location farther from the pressure screw is for ripping the chain pins. You can learn more about using such a tool from the following.

How to know when the chain needs to be tensioned?

Reasons for loosening chains:

  • Fixed gear. Driving in this manner implies no phase shifter. Because of this, the nuts responsible for the rear axle can become a prerequisite for loosening the chains. It is necessary to inspect the area of ​​the nuts for the possibility of loose tightening, in which case the wheel is subject to sliding and the distance between the pedals and the wheel decreases.

Ultimately, the total mechanism is released and falls out. To fix the problem, you need to loosen the rear part and move the wheel to its place. Then tighten the nuts tightly.

  • Transmission system. With this design, the root of the problem lies in the switch. In the future, this component must be adjusted. Switches on both sides act on the structure, and in turn move along different sprockets.

It is necessary to inspect the switch, which has a structure of two screws. The screws are used to stop the movement of the switch, so make sure they are in the correct places.

  • Damage. Switch malfunctions due to damage are NOT a rare cause of circuit malfunctions. Rear derailleur Most prone to breakage, fragile structure. After a blow or fall, it can bend inward towards the spokes. To verify this problem, you should inspect the rear derailleur.

Rollers Must be parallel to each other. As a result, the structure moves vertically from above towards the control roller in the environment of the gear selector. For diagnostics, you should compare the roller with an asterisk to make sure there is no side bevel.

The solution is to remove the switch and straighten it. It must be remembered that the element is carefully disconnected so as not to cause even more harm.

  • Other reasons. When buying a new sprocket or chain, measure its length. Manufacturers often make chains longer than required. Too long will be weak amid heavy gear loads.

Adjusting chain tension on bicycles without gears

For bicycles to function flawlessly without speeds, their chain need not be taut. It is necessary to ensure its free sagging for a length of up to 5 mm. And to pull in this way, you need to perform a certain set of actions in the correct sequence:

  • The vehicle is turned upside down.
  • Loosen the rear wheel. unscrew the nuts or fixing eccentrics.
  • Adjust the chain slack to the required value. To do this, you need to carefully move the wheel along the inclined grooves (dropouts).
  • At the end of the adjustment, the wheel should be fixed to its original position again. In this case, the wheel should be parallel to the carriage shaft.

If the chain is too tight, it will be hard to pedal. And the elements of the chain drive will very soon become unusable. It is also bad if the bike chain is too slack. She will simply jump off the stars at a certain moment and it will be impossible to go further.

When the wheel literally rested on the dropouts and there is absolutely nowhere to move it further, but the bicycle chain is dangling, you will have to remove a couple of links from it. In all likelihood, it was stretched or not at all the size for a particular model.

Features of chain tension on a bicycle without gears

When working with a regular bicycle, remember that it is forbidden to tighten the structure too tight. Normally, the value is allowed NOT more than 5 mm.

Chain tensioning sequence:

  • The bike should be turned over and a soft cloth should be placed under the seat to avoid damage.
  • The rear wheel is attached with two nuts. They should be loosened for comfortable chain mounting.
  • The wheel is moved along inclined grooves to set the required level of sagging.
  • After adjustment, the rear wheel is secured back onto the nuts, tightening firmly. No need to make great efforts in order NOT to damage the elements.
  • The mechanism must provide free rotation of the pedals. That is why, after installation, you should check the bike in operation. Also, after the completion of the work, it is necessary to Make sure that the wheels are parallel to the carriage.

Chain tension on speed bikes

Automatic chain adjustment on two-wheeled vehicles, equipped with a speed mechanism, is carried out thanks to the rear derailleur spring. Problems begin to manifest when the element is stretched so much that the spring is no longer able to compensate for the slack. The solution to how to tighten the chain on a speed bike is to remove the links. Before the procedure itself, you need to find out the number of extra elements in the bundle. This is done in one of two ways:

    Will switch to large sprockets at the front and rear. Pull the chain to release the rear derailleur until it stops. Add 2 links to the resulting length. This will be the optimal size.

Set the forward speed to the largest sprocket and the reverse speed to the smallest. Pull the chain so that the rear derailleur frame is strictly perpendicular to the ground and forms a flat horizontal line with the rollers. This position is an indicator of the correct length, the excess must be removed.

If the bike has shock absorption on both wheels, then you can determine the optimal length by pushing the swingarm. it should get into a position with the front cassette as far away from the ratchet as possible. In this position, the chain is measured, and the excess size is subsequently removed.

Chain tension on models without gears

On bicycles, and not equipped with a gearshift mechanism, the chain should have a small degree of freedom. The allowable sag is within 5 mm. If the indicator exceeds the norm, the tension is performed:

  • Place the bike with the wheels up.
  • Find and loosen the rear wheel mount. Depending on the design, classic nuts or eccentrics may be present.
  • Slowly shift the wheel backwards, thereby reducing the sagging to normal. The movement of the wheel is carried out along specially designed grooves, called dropouts.
  • Fix the wheel in the new position. Pay attention that it is parallel to the carriage shaft.
  • How to tension the chain on a simple and fast bike

    The chain is an important component of a bicycle, without which movement is simply impossible. Its service life depends on the regularity of maintenance and the integrity of the interacting devices. Visually, the wear of the part is manifested in the form of stretching, jumping off or slipping. In this article we will tell you how to tighten the chain on a regular and high-speed bike.

    How to remove links

    Since excessive length is the main prerequisite for why the chain flies on a bicycle, it should be reduced. On two-wheeled vehicles without a high-speed mechanism, a collapsible chain is often installed. There is a lock on one of the links, having opened it, it will be possible to remove the required number of elements. This option is the simplest and does not require special equipment.

    On mountain, professional and other types of bicycles there is a one-piece chain, the links of which are held by rivets. The best method for removing excess length is to use a tool called a squeeze. It acts as follows:

    • A link is installed in a specially designed groove.
    • Rivet matches the pop-up tool stop.
    • The stop is screwed into the rivet, which leads to the last falling out.

    Almost all pomace is universal, that is, rivets are designed for both men and for its installation.

    If you have a special tool at hand, you can try to file the pin heads with a file. In the field, any devices are used that allow you to knock out a rivet from its groove (for example, a nail or a thin metal tube).

    Now you know how to tighten the bike chain or remove excess length. It should be understood that the removal of links is done only once. If the chain is stretched again, it must be replaced with a new one. Otherwise, other interacting mechanisms may suffer and repair will require much higher financial costs.

    What to do if the chain is loose on a mountain bike?

    If you encounter the problem of chain slack on a mountain bike or any other that has several gears, then in such a situation it is changed. The fact is that in such bicycles the machine is responsible for the chain tension. With the help of a spring, it constantly and automatically adjusts the tension in which the chain mechanism should be.

    To save money, some craftsmen “cut” the chain, that is, cut it and reduce the number of links. In this case, the links are connected with a special lock. This option is, of course, also possible, but it is important to understand that a stretched chain is a worn-out mechanism and it will not last long.

    When buying new chains, it is important to know that they are different and may NOT fit your Loyal two-wheeled other. First of all, you need to make sure what chain pitch is used on your bike model. And you also need to decide on its length, which is usually measured in the number of links.

    Learning to adjust the chain drive correctly

    On the simplest single gear bike, tensioning the chain is all it takes with one wrench, just loosen the two rear wheel nuts. Most often this key is either 17 or 15.
    First, the bike needs to be turned upside down, and then slightly loosen the two nuts on the rear wheel. It is not necessary to unscrew them completely. After the nuts have been loosened, the wheel must be moved back a little. At the same time, there is a need to hammer in various wedges and insert something between the frame and the wheel, the tension of the chain system should occur with minimal effort, under the wheel’s own weight.

    After that, the nuts can be tightened, it is best to use a wrench with a dynamometer for this, so that the correct tightening torque is observed. If the nuts are loosely tightened, the wheel may slip sideways on the road. And if you have a lot of strength, you can rip off the thread of the nut or even the wheel wasps.

    Improper chain maintenance is the cause of an accident

    In the event of a collapse or breakage of the bicycle chain, with the best outcome, the driver will get off with the fact that he will NOT be able to continue to ride. But often there are more serious consequences. For example, if there is no special guard on the rear wheel, the chain can fall into the spokes, but here the outcome is unfavorable in all cases.
    Under any combination of circumstances, the spokes of the rear wheel will be bent, and an eight will form on it, and the repair of such a breakdown will cost a pretty penny. And there is also the danger that the driver will injure himself or pedestrians, as his rear wheel gets jammed.

    The next risk of chain breakage or loosening applies to bicycles that do not have a handbrake. Since here the entire brake system is located in the rear wheel carriage, therefore, the driver will NOT be able to brake in the usual way. It’s even scary to imagine if this happens at high speed.

    How to properly tension your bike chain and why it matters

    Everyone knows why you need a chain on a bicycle. But not everyone knows all the subtleties of its device and what danger its malfunction conceals in itself. Therefore, it is so important to know how to properly tighten the chain.

    The bicycle chain is one of the most important parts of this type of transport. Its main task is to transfer the energy of the cyclist’s muscles to the rear wheel. In addition, they are the driven link of the bicycle gearbox. This mechanism is formed due to the fact that the driving sprocket (which is on the pedals) is always made larger than the driven sprocket (which is on the wheel). Thanks to this, a law of leverage is formed, which allows you to transform one type of energy into another.

    If we talk about those bicycles on which there are several gears at once, then here the chain is assigned an even greater role. In such a system, the chain drive acts as a floating transmission link that connects the drive sprocket to the driven one. At the same time, it is not difficult to guess that if the chain jumps off, the transport will NOT be able to go further. And it happens quite often if the cyclist forgot to tighten the chain.

    Reasons for loosening chains

    Before you begin to tighten the chain, it is important to understand one truth. It’s just as bad for a bicycle when the chain is too tight, as it is when the chain is too tight. The surest way to check the chain tension is to push it from top to bottom, while the normal level of sagging should NOT be more than 1-1.5 cm.If this value is far beyond its limits, the chain system must be tightened.

    Another symptom that should alert the driver is if the chain began to slip.

    To begin with, the problem of sagging is most often encountered by owners of regular single-speed bicycles. The thing is that here the chain is NOT able to tension automatically, as in mountain or other similar types of bicycles.

    But why do the chains start to sag? There are two reasons for this. Firstly, any chain has the property of stretching, do not look at the fact that it is made of metal. At the same time, cheaper options stretch more, but expensive branded products practically do not have this property.

    Secondly, the chain system can weaken if the rear wheel nuts were not tightened well, in this situation, under load, it shifts slightly forward and the tension of the chain mechanism weakens.

    How to take care of chains

    Like any other mechanism, the chain system needs maintenance. All you have to do is lubricate all links thoroughly from time to time. In the event of rust formation, the metal becomes thinner, in addition, the link rollers jam, and the device’s resource is sharply reduced.

    It is also important to know that during operation, the elements of the chain system run in to each other. At the same time, various cavities, notches and other minor defects are formed, which, no matter how strange it may sound, ensure the stability of the system. If the chain is removed, and then placed in a different way from Chagall’s earlier, or is completely inverted, accelerated wear will occur. In the worst case, it is also possible for the chain to fall off more frequently. The chain system also wears out quickly if pulled too tight.

    How is the process of tensioning the chain on a regular bicycle

    This term refers to a bicycle mechanism containing one rear sprocket. There is only one technology. to displace the rear wheel hub. The detailed process is described below.

    Before starting such a procedure, you need to make sure that the chain needs tightening. We carry out the usual test. Just pull the chain down as far as possible. If the lowering distance is more than 1.5 cm, then adjustment is necessary.

    The opposite situation. The chain did NOT pull back even 5 millimeters. This means she is in a state of “guitar string” and needs immediate relaxation.

    • Place the bike in the Repair Pose, wheels up.
    • Bolts and other elements that serve to fix the rear wheel need to be loosened (it is not necessary to unscrew completely).
    • We adjust the chain, move the wheel in relation to the star.
    • Let’s make the required tension, evaluate the perpendicularity of the hub axis, focusing on the longitudinal one of the bike itself.
    • We fix the wheel with fasteners.

    If, for some reason, such a procedure cannot be carried out, it is necessary to use squeezes to remove unnecessary links and by this method to achieve the desired parameters of the product. How to do it. described below.

    Installation details of the bicycle chain

    The bicycle cannot be called a very complex device, there are more complex ones. But still, there are several fundamental and irreplaceable elements in its design, on which the operation of the entire mechanism directly depends. The chain always takes an important place. It will work for a long time only in the case of correct, timely and complete care.

    It is necessary to monitor its work and promptly respond to emerging problems. For example, a properly installed and serviceable chain is not obliged to emit extraneous sounds in the form of crackling and squeaking. During use of the bike, this element can stretch and be subject to wear.

    If the installation and adjustment of the chain was done correctly, then it should sag by 10-12 mm, no more and no less. Pulling the chain with your fingers, it should move 1-1.5 cm from its original position. With more pulling, it is necessary to urgently tighten the chain. These regulations apply only to two types of cycling: models with no speed switch or with an installed planetary gearshift mechanism.

    When a new chain is installed, the tension level must be adjusted, and after three trips, it is necessary to start tightening it. The new mechanism is prone to fast stretching.

    How to determine when a chain needs to be replaced

    The method is based on measuring the length of 24 links. As we know, the length of one link is 12.7 mm, respectively, on a new chain, the length of 24 is 304.8 mm. If the length of this section exceeds 307.3 mm, then replacement of the chain is desirable. You can also use the special tools presented in the picture below.

    How to understand that the chain needs to be tightened

    On bikes that do not have derailleurs or with a planetary hub, it is quite easy to check the chain stretch. Pull it down with your fingers until it stops. The distance that she has traveled does not have to exceed 10-15 mm.

    But it should be noted that the chain does not have to be overtightened. Therefore, if the bike travel is less than 5 mm when pulling down, it should be loosened. Excessive tension leads to high pedaling forces and increased wear of the transmission, and too loose tension leads to the fact that it can fly off the front or rear sprockets.

    Link removal

    Conventional speedless bikes are equipped with collapsible chains, one of the links of which has a special lock. But on professional bikes, one-piece chain structures are installed, all the links of which are perfectly riveted.

    However, disassembling a one-piece bicycle chain is also easy. And this can be done in one of two possible ways:

    • Grind pin heads on one of the chain links with sandpaper;
    • Or Using a universal tool. squeeze.

    By the way, pomace is not called “universal” for nothing. It can not only squeeze out the pin, but also reliably fix the newly assembled bicycle chain. Indeed, in the pomace (well, at least most of them) there are a couple of special functional and technological grooves. And one of THESE grooves the pin is pressed out of the roller, and the other is pressed in. As for the installation place, which is located on the squeeze a little further from the pressing screw, it is intended for riveting the chain pin itself.

    How to remove excess bike chain links?

    It is necessary to shorten the mechanism when there is sagging, high loads, if the mechanism is used for a long time, or when changing sprockets.

    How to shorten the chain correctly:

    • The chain is thrown onto large stars in front and behind.
    • One link breaks.
    • The caliper must be in a horizontal position, for this, the links should be tightened as much as possible.
    • The last step is to remove or add extra links.

    What bicycle chains exist, how to tighten the chain on a single speed bike, on a high speed bike, the method of removing links

    Friends need to be loved. Even if they are two-wheeled. Such a relationship involves skilled caring for your friend. The chain is tensioned in the name of its safety and the life of the bike. Let’s analyze the question of how to tighten the bicycle chain correctly, quickly and efficiently.

    Conclusion

    Caring for your bike is extremely important. As one of our readers wrote, “as you look at the equipment, so it carries you.” After reading this article, you fully learned how to tighten the chain on a bicycle. Keep an eye on your two-wheeled friend, and he will delight you for a long time with his clear and durable work.

    If the bike is without gear

    For a bike that does not have a gearshift system, the chain mechanism should only have 5mm slack. In order to achieve the correct operation of the transport and NOT to encounter certain problems on the road, it is necessary to tighten the chain in accordance with certain rules:

    • Position the two-wheeled vehicle so that it stands on the steering wheel and seat, and the wheels are located on top.
    • On the rear wheel, you will need to loosen the fastening nuts or eccentrics.
    • By moving the wheel along inclined grooves (dropouts), it is necessary to achieve the correct sagging of the chain mechanism.

    On this, the installation of the chain could be considered complete, if NOT for a number of subtleties, which can greatly complicate this whole venture:

    • The rear wheel is fastened only if it is located strictly parallel to the carriage shaft;
    • If the chain on the bike is too tight, then pedaling will be complicated, and the mechanism itself will quickly become unusable;
    • With a very sagging chain, the cyclist will often have to stop and correct it;
    • The removal of links on the chain mechanism is required if, during its installation or pulling up, further adjustment of the wheel according to the Dropouts becomes impossible, and the chain still sags.

    How to select and install a chain damper

    The damper is a simple structure made of high quality metal, which prevents the element links from falling off. For proper functioning, it must be correctly installed.

    Installation order Silencer:

    • Dismantle the pedals;
    • Remove the gear shift stars from the bike. On some models, the carriage must be removed;
    • The largest star, which will be rocked, must be installed in place of the middle one;
    • Fix the structure in place of the carriage protrusions;
    • Lubricate all rubbing elements;
    • Put on the chain and tension it correctly.

    [Attention type = red] Important! The damper should be extended towards the star so that it does not interfere with the free operation of the entire gearshift system. [/ Attention]

    Following the instructions above, you can understand how to tighten the chain on a sports bike or do the same operation on a simpler two-wheeled vehicle.

    How to shorten the chain?

    Normal speedless bike chains are collapsible. One of the links has a special lock. Its opening will allow you to remove unnecessary links or add new ones.
    [Attention type = red] Important! Before proceeding with the removal of the extra links of the solid-riveted chain on a high-speed bike, a special squeeze is purchased. [/ Attention]

    With its help, you can gently rivet the clamps, leave the required number of them, and then re-rivet.

    There is another solution: in the absence of a tool, the pins on the links are ground using sandpaper. After that they are removed.

    On bicycles without speeds

    Before starting work with this element of an ordinary bicycle, which differs from other types, you should know the basic rule. you cannot pull the chain to the state of the string. The normal state of this node is considered sagging up to 5 mm.

    How to tension a chain on a regular bicycle, sequence of operations:

    • The vehicle rolls over. To avoid damaging the seat or the surface of the steering wheel, small pieces of soft material can be placed under them.
    • The rear wheel is supported by two nuts. To work with the chain, they must be loosened.
    • As a consequence of wheel movement along inclined grooves, it is necessary to adjust the required sag.
    • After the recommended distance of 5 mm has been reached, the rear wheel must be secured with 2 nuts, which must then be carefully tightened. NOT worth the effort.
    • An overly tensioned mechanism will prevent the cyclist from pedaling freely. Also, when returning the transport to its original state, carefully monitor that the wheels run parallel to the carriage shaft.

    Reasons for a meeting or rupture

    One of the main parts of a bicycle is the chain. But even with normal driving, it can collapse or break. The main reasons for the breakdown:

    • Damage to one of the stars of the transmission system. Speed ​​bike transmission systems are divided into collapsible and non-collapsible. Star replacement is possible in a collapsible system. The non-separable transmission system is completely changed, complete. If one star is damaged, driving is possible at speeds that remain serviceable.
    • Incorrect speed setting. The front and rear derailleurs have special bolts that adjust the transmission. If these bolts are not set correctly, then there is a possibility that when changing gears, the chain will fly off.

    How to tension the chain on a bike at speeds? The high-speed design provides tension on the element links by increasing the spring rate of the rear derailleur. If the length of the element links is incorrectly selected and the subsequent replacement, the switch will NOT provide proper tension.

    If there is too much slack, the chain will hit the frame and make gear shifting difficult. Also, do not put too short a mechanism, the tension will accelerate the wear of the entire speed mechanism.

    [Attention type = red] Important! Sometimes, when installing a new chain on a speed bike, you need to shorten its length, remove excess links. [/ Attention]

    This can be done in two ways:

    • Pull the chain over the largest front and rear sprocket. We pull for it, retraction of the rear derailleur to the maximum forward. Add two links and get the optimal chain length.
    • We transfer the chain from the front to the largest star, from the back to the smallest one. Pull it up to a position when:
    • The rear spreader frame will point straight down;
    • Switch rollers Must be in one vertical line.

    Tensioning the bike

    The mechanism can be pulled independently, both on high-speed models with gear shifting, and on bicycles without them.

    In order to properly tension the chain on the bike, especially if it starts to slip, you need wrenches (which usually come with the vehicle) and a little patience.

    Some tips on how to chain a speed bike

    A bicycle chain is one of the main components of a bicycle. Many are confused by the question of how to tighten the chain on a high-speed bike? Special skills and the presence of a special tool for this operation is NOT required. You can do the actions yourself, just follow the instructions exactly.
