How To Tighten The Chain On A Kids Bike

Diagnostics

First you need to figure out whether you need to tighten the mechanism? On ordinary bike concepts, everything is quite easy. The method for adjusting the chain on a bicycle is simple enough.

  • Turn your two-wheeled vehicle upside down, pull the mechanism down with your fingers until it stops. (If the chain stretches and sags NOT more than 10-15 mm, then there is no need for Pulling).
  • If the tension of the bicycle chain does not lower it below 5 mm, it is necessary to immediately loosen.

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.

Chain break

If you switch the speed at the moment of loading, let’s say when climbing a mountain, a chain break is likely. When a chain break occurs, the link often breaks or breaks. In case of riveting, you can try again to crypt the link. Since this is done with a chain puller, it is advisable to keep the tool close at hand. If a link breaks down, it must be removed together with the adjacent one. Then the chain is riveted with a puller.

Installing a bike is a simple job. It is enough to pull the rear derailleur itself on the weakened chain and put it directly on the front sprocket.

Cleaning and maintaining the chain

Preventive measures to minimize transmission wear Should be carried out regularly. To do this, remove the contaminated chain and wash it with a solvent. There are special devices that can help with this process and keep your hands clean.

They are called “washers”: they are a box with special brushes, rollers and guides, filled with a liquid that washes away dirt particles. If he carries out such a procedure regularly, then the problem of how to tighten the chain on a bicycle will not bother you, and the part will successfully serve for several seasons.

If cleaning has not been carried out for a very long time, then rust will form, which is much more difficult to remove. It is necessary to load the chain into a container with a corrosion converter or kerosene (it is best to use an aviation one, since it contains the least amount of impurities) and hold it for several days. Then it must be removed, cleaned with a metal brush and left to dry in the sun. After a while, each link must be lubricated with oil from a special oiler and set in working position. We have already discussed how to tighten the chain on a bicycle at the beginning of the article, so there will be NO difficulties in this matter. It is important to follow logic and your own intuition.

Ordinary bike

To tighten the chain on a regular bike, you need to set the transport with the wheels up. This is the most comfortable position for loosening the rear wheel nuts. When unwinding, it is easy to set the optimum sag and tension of the bike. You need to move the wheel along the grooves. The mechanism is fastened only in a parallel position to the carriage shaft axis. The correct sag is 5 mm. When tightening the chain, there is difficulty in pedaling. Insufficient tension will cause the mechanism to jump off. Sometimes there is a tight stop of the wheel in the edges of the grooves and the extra links are removed.

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.

Weak tension

The bike chain is mostly loose due to weak tension. On newer bike models equipped with a special tensioner, the pull-up process is automatic. True, the chain on such bicycles can come off due to a malfunction of the shifting mechanism. Try changing the cable on the derailleur. If this does not help, replace the switch itself completely.

On older models, the chain is tensioned by hand. Unscrew the rear wheel and tighten it, adjust the position of the wheel. Do not tighten too much, the chain may break during the operation of the bicycle. After completing this procedure, properly lubricate it. This will extend the life of the chain mechanism.

How to chain a child’s bike

Children’s bicycles are designed in exactly the same way as regular bicycles (not speed bikes). Therefore, in order to tighten the chain on children’s bicycles, you need:

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:

  • 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.

Loose chain tension

On regular road bikes, the chain is not that difficult to tighten. To do this, you need to remove the rear wheel and pull back in the fork. Weak Tension and High Tension are equally problematic when driving, so it is important to stop in time so that the chain has medium tension.

If it is stretched to such an extent that it is no longer possible to cope with a simple suspension of the wheel, but you DO NOT consider it necessary to change it, since it slips noticeably, then it makes sense to remove it and knock out one or more links and shorten it in this way. This is not a difficult action. In this case, your task is to ensure that the chain length is the same as it was originally. If you are NOT sure if you can re-fasten the chain, then it is better not to take this step.

When to tighten the chain?

1) On the move, the chain of the roadman jumps off a little and a terrible rumble is heard.

2) You already feel that it is not long before point 1).

3) On a speed bike, gear shifting is NOT easy to adjust.

4) You yourself realized that it’s time to tighten the chain :-).

Let’s start with a road bike. everything is very simple on it.

In order to tighten the chain, it is necessary to remove the wheel and pull it back in the fork so that the chain is taut. It is not necessary to tighten the chain very tightly or weakly. you need to stop at an average tension.

But what to do if the chain is already much longer than the ideal, that is, it is so developed that you cannot tighten it by simply pulling the wheel? Everything is very simple. you need to knock out one or two links of the chain, so that the chain acquires almost its original length. It’s very simple and I will not dwell on this problem. The main thing is to reattach the chain well. You will understand the rest on the spot.

Now let’s talk about a speed bike.

The first thing to do is to try to tighten the chain in the above ways, if you didn’t succeed then in a speed bike there are several simpler ways:

Remove the chain from the gears, knock down the stopper on the switch and begin to twist the part of the switch, where the guide sprockets are located, towards a higher spring tension. It is allowed only on an old switch with a weakened spring. You just rip the spring on a new one!

You will laugh, but sometimes just pulling up the derailleur cable is enough.

As always, I wish you a successful renovation! Don’t forget to miss your chain!

Replacement

A bicycle drivetrain also has a lifespan. One piece is designed for 3-4 riding seasons. After which a replacement will be required.

There are many reasons why a part may wear out.

  • Mechanism age.
  • Weather conditions that adversely affect the performance of this part (Rain, snow, dirt, dust, small particles, etc.).
  • Chain production quality.
  • Improper care of her.

When all the chain pulling steps are completed, there will never be any difficulties with the transmission. All the experience that can be accumulated in the process of tightening the chain will definitely come in handy. You can also share your experience with friends and family. After all, every person who drives such a vehicle may have a similar problem.

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 tighten a chain on a bike at speeds

In relation to high-speed vehicles, there are two more ways to properly adjust the tension of the bicycle chain.

Method onePulling the chain on a sports bike:

  • Remove the links from the gears;
  • Gently knock down the stopper on the speed switch;
  • Rotate the switch towards the spring tension. Thanks to this action, the part is automatically tensioned to the desired level.

Method two. just pull up the switch cables (in some situations, this method may come in handy).

These methods will perfectly cope with the problem of chain stretching.

If the chain falls off on a mountain bike

If the mountain bike chain piece stretches and falls, then the Pull Up will not help. In this case, a replacement part will be required. Because in this case, the mechanism is responsible for the operation of the transmission. The spring in this type of transport is responsible for the operation of the chain and automatically adjusts the tension in which the mechanism should be.

Some craftsmen solve this problem quite simply. Tear apart a metal part, remove several links and fasten it with a special lock. But, unfortunately, this method is not always effective, since it will NOT be able to please with its work for a long time.

We will tell you how to fix circuit faults and how to properly use a special tool for circuit assembly (chain wringer or circuit breaker). Below you will find Step by step instructions that will help you repair the chain yourself.

While chain breakages are rare, they can quickly ruin a good day you were going to cycle. And if you have NOT encountered such breakdowns yet, having driven many miles, your time may soon be approaching. If, unlike an experienced mechanic, you have the right tool and the necessary knowledge to cope with such a breakdown, then you will find yourself in a hopeless situation. Forcing the chain is a must-have tool that should be in your backpack. Fortunately, a squeeze is a small tool and it only takes a few minutes to repair a chain, you just need to learn how to use it.

  • Chain extractor or universal tool kit with chain extractor included

Before you start doing anything, you need to understand what type of chain is installed on your bike. If you have a Shimano chain, you either need to connect the gap using a reusable chain link from a second manufacturer or install a new Shimano link. If you do not have either one or the other, you can follow the steps, what is written, to put your bike on wheels and leave the area in which you find yourself, but be careful, because The restored connection in the chain will not be as strong as when the link is replaced with a new one and the chain may break again. I would recommend that you take your bike to the nearest workshop for a complete chain repair before you head out on a new ride.

There are many reasons why your chain might break and there are many riders who prefer one brand over another. But the reality is that any chain can break and there are many reasons why this happens. The reasons can be anything from a failed shift under load, which leads to the disconnection of the outer chain plate from the pin, high wear, or even incorrect installation and setup of the bike. Despite the assurance of many riders that the chain must be weaker than the force exerted by the foot to break, there is always a reason why the chain breaks. The chain can break when you train your start, but it is not your little efforts that are the cause of all troubles!

The first thing to do is remove the broken chain from your bike. This will make it much easier to remove the broken link from the chain and check the remaining links, which may be bent or twisted and the floor is a prerequisite for jumping under load. When you look at a broken link in your chain, you can see different things. You may have different combinations of halves of dad (inner link) and mom (link with outer plates) type links depending on how the chain broke, but in order to connect them back without spare links, you will need to use squeezes and connect inner link (dad) at one end and outer link (mom) at the other.

Broken link to be removed.

Let’s good luck with the broken part. Some chain pushers are equipped with two chain link slots. The inner section serves only for repairing hard links, which may appear after the chain is repaired, but you will always need to use only the outer slot for inserting and removing links. If your squeeze has only one department, then you don’t need to think about it. One more thing you need. Please note that some of the squeezes have a screw adjustment to work with links of different widths. If you have one, just screw the trim all the way down after you install the link in the squeeze slot. This way, the link will be held in place while you work with it. When you remove damaged links, you need to keep in mind that the chain length should stay as close to its optimal length as possible. To leave the inner link (dad) at the end, simply remove the entire pin of the broken link from its hole. The outer plates will fall out and you will have only the inner link. Please note that the inner link roller must remain in place (the round roller between the inner link plates), It should not fall out, although it sometimes tries to do so.

Forcing the chain with two slots: an internal slot for loosening rigid links and a standard external slot for pressing out and pressing in the chain pins.

The next step is to prepare the opposite end of the chain with the outer link (mom). This part is more difficult. Place the chain link first in the outer section of the chain link and make sure the chain link pin is exactly aligned with the link pin. Start pushing on the pin, but the key is to stop before it is completely out of the outer plate. The goal is to squeeze it outward enough to remove the broken link, and if done correctly, you can pull it out by slightly bending the outer plate. When you pull out the broken link, you will see that the extruded pin is protruding into the link from the outer plate by about a millimeter. If you accidentally squeeze a pin out of a link entirely, you’d be better off doing it all over again on the next section of the chain, because It is not recommended to press the pin into the link if you squeezed it out completely. Also, by leaving the pin in the outer link plate to stick out a millimeter inward, you’ll be able to connect the chain much more easily when you put it on the bike, as it does. When you connect the inner link at one end and the outer link at the other, they will hook slightly and you do not need to hold the chain.

Chain ends with a new outer link (mom) on the left and the other end with an inner link (dad) case.

You are now ready to install the chain on your bike. To reduce chain tension (this will make it very easy to install), move your rear derailleur to the smallest sprocket and do the same on the front (if you have one). Stretch the chain as it should be in normal condition, but make sure that the pin, which is at one end of the chain and almost completely sticks out of it, sticks out to the outside of the bike, so it will be easier to work with.

Chain pin Protrudes outward from the bike and is ready to install.

Connect the two ends of the chain together. If you Pull out the pin at the end of the chain with the outer link as needed, you MUST COUPLE the ends of the chain easily and do not need to be held back from disconnecting. If this is not the case, you will have to keep the chain from disconnecting when you press the pin into the link. You can use this method: take a 4-inch piece of an old knitting needle, bend it into a letter “C” and CONNECT your chain with it. Before you press the pin into the chain, make sure the holes in the link to be connected and the pin are straight. If the pin is not in line with the holes in the outer link plates, you will simply break the link, or the pin will NOT fall into the hole and on the opposite plate, as a result, the chain will be unreliable and unsafe for driving. When Make sure everything is in alignment, start pushing on the pin until it protrudes the same amount on both sides of the outer link. Depending on your chain, the ends of the pin may be very close to the edges of the outer plates. It is important to make sure that the pin extends the same amount at both ends. Carefully check the new connection for defects in the chain, for example, twisting of the plates during installation.

Using a squeeze to install a pin.

There is a high probability that at the new connection point, the chain will not rotate. This is because the outer plates are pressed against each other with a squeeze when you press the pin into it. You can easily find such a rigid link connection when you pedal backwards and observe the chain on the idler roller. There are two ways to fix this situation: by hand or by squeezing. I prefer to fix it with my hands. Take the chain with one hand on one side of the link and with the other hand on the other side, so that the thumbs are in the place of the rigid connection. Bend the chain lightly from side to side directly at the rigid connection. One or two attempts are enough for the chain to turn freely to the place of the new connection. Another method of correcting flexion is to use the internal squeeze slot to slightly nudge the pin at the rigid connection. This method is also very effective.

You can work out where the links are rigidly connected with your hands. Before you hop on your bike and get ripped off, always make sure you get it right. There should be no bent or cracked outer link plates in the chain at the new connection. Go through all the gears and pedal with a little effort first before you start doing the tricks of riding your rear wheel on your balcony railing! Note that you removed the links from the chain and it is now shorter than it was. If the chain was originally the right length, now it may be too short, especially on large stars. Be very careful or you will need to replace the rear derailleur and cock!
