How is the chain on the bike

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

While chain breakages are rare, they can quickly ruin a good day on your bike. And if you haven’t experienced such breakdowns yet, having driven many miles, your time may be coming soon. If, unlike an experienced mechanic, you do not have the right tools 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.

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 will need to either connect the gap using a reusable chain link from another manufacturer or install a new Shimano link. If you do not have either one or the other, you can follow the steps that are written to put your bike on wheels and leave the area in which you find yourself, but be careful, because the restored link 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 the other. 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 improper installation and adjustment of the bike. Despite assurances from many riders that the chain must be weaker than the force applied 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 effort that causes all the trouble.!

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 rest of the links, which could be bent or twisted and cause jump under load. When you look at a broken link in your chain, you can see different things. You may end up with different combinations of dad (inner link) and mum (link with outer plates) halves depending on how the chain broke, but in order to connect them back without spare links, you will need to use a squeeze and connect an inner link (dad) at one end and an outer link (mom) at the other.

Broken link to be removed.

Let’s remove the broken part. Some chain pushers are equipped with two chain link slots. The inner section only serves to repair the hard links that may appear after the chain is repaired, but you will only need to use 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 to pay attention to, some 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 consider that the chain length should stay as close to its optimal length as possible. To leave an inner link (male) 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 must 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 aligns exactly with the link pin. Start pressing on the pin, but the key is to stop before it is completely out of the outer plate. The goal is to push it outward enough to remove the broken link, and if done correctly, you can pull it out by bending the outer plate slightly. When you pull out the broken link, you will see the extruded pin protruding into the link from the outer plate by about a millimeter. If you accidentally squeeze a pin out of a link entirely, you might be better off doing it all over again on the next section of the chain. it is not recommended to press the pin into the link if you squeezed it out completely. In addition, leaving the pin in the outer link plate to stick out a millimeter inward makes it much easier to connect the chain when you put it on the bike. 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 (female) on the left and the other end with an inner link (male) on the right.

You are now ready to install the chain on your bike. To reduce the 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 is almost completely sticking out of it, sticks out to the outside of the bike, so it will be easier to work with.

The chain pin protrudes outward from the bike and is ready to install.

Connect the two ends of the chain together. If you have pulled the pin on the end of the chain with the outer link as much as needed, you should easily interlock the ends of the chain and do not need to be kept 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 “C” shape and use it to hook your chain. 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 to ride. When you are sure everything is in alignment, start pushing down 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 the chain will not rotate at the new junction. 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. Grasp the chain with one hand on one side of the clamped link and with the other hand on the other side, with your thumbs in 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 rotate freely in 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 dash away, always make sure you’ve done the right thing. 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, then now it may be too short, especially on large stars. Be very careful or you will need to replace the rear derailleur and cock!

How to shorten a chain on a bicycle: features of the procedure

Cycling is largely done with a chain. Over time, it sags, which makes the trip more difficult. This raises the question: how to shorten the chain on a bicycle? You can do this procedure yourself if you use simple practical advice.

What are the chains?

To understand how it works, you need to know the types of bike chains and their features. All bicycles now use single-row roller targets with a pitch of 12.7 m.Each link has outer and inner plates, saws, rollers and rollers.

The number of speeds changes the width of the product. If there are many sprockets, then the chain is narrow. Products are distinguished by the presence and absence of a lock, which serves for convenient dismantling and installation of the chain.

What affects chain elongation?

The wear of the chain pins (pins) is due to a number of factors. This is due to the accumulation of old oil between the structural parts, which attracts dust and debris. Elongation occurs when the chain is loaded excessively when driving up steep inclines.

A common cause of target sagging is the end of its useful life. The product deteriorates from impacts, metal corrosion. To eliminate the inconvenience of driving, you need to know how to shorten the chain on your bike. After that, the vehicle is again suitable for a comfortable ride.

Determining the required length

Before you understand how to properly shorten the chain on a bicycle, you need to find out how long it should be for normal movement. To determine this, the chain must be thrown over large sprockets in the rear and front undercarriage.

Then you need to open one link. At the end, you need to tighten the chain as much as possible. Add a few centimeters to this length so that there is no overvoltage. This will be the optimal length.

Getting ready for work

To make it easier to work with the chain, you need to clean it. This requires a small rag to remove debris and dust. Only the material must first be treated with kerosene. A special wash is also used, for example, liquid AB-80 or WD-40.

Tools

When there is no squeeze, you can use the tools at hand. All you need is a hammer and a metal rod, which will be a punch to eliminate the link axes. Nuts are also required and must be placed under the links.

Pomace shortening

How to shorten a bicycle chain using a squeeze? To do this work using a special tool, you must go through the following steps:

  • Place the squeeze so that its core is in the center of the link axis.
  • Rotate the tool to force the axis out of the link.
  • Disconnect the circuit, then do the same procedures with other sections.
  • Eliminate unnecessary links and fasten the structure.

Once you understand how to shorten a chain on a bicycle, you need to determine how it can be connected. A narrow half-link is inserted between the wide cheeks. Then the axle enters the bore of the bushing. Then you need to check the mobility of the links. If it is of poor quality at the joint, the hinge should be developed with pliers.

Shortening without squeezing

How to shorten a bicycle chain without squeezing? If there is no special tool that is used to separate the links, then this can be done without it. As mentioned earlier, the alternative is a metal pin, a nail. You also need a hammer that will serve to knock the axles out of the links.

This method requires caution, since careless actions can lead to deformation of the link plates. To avoid this, nuts are placed under the chain. If this is the first time this work is done, then it is best to practice. Old chain or individual links can be used. This takes skill. Therefore, before working on correcting the chain with a hammer and a punch, you need to perform these actions many times, and then evaluate the result of the work.

For the product to last a long time, care must be taken. The chain must be lubricated regularly to prevent the accumulation of dust and dirt. It is necessary to follow the rules for using the bike, which will extend its service life. Also, no permanent repairs are required.

Thus, this procedure is simple, the main thing. observe safety. Each bicycle owner can shorten the chain independently. After that, the transport will again serve for travel.
