How to tension a chain on a speed bike

Link Removal Process

Consider a modern way to adjust the length of the chain using a device. squeeze. Its low price more than compensates for all costs.

The tool design includes two slots. The first one squeezes out a pin, the second one presses it in.

  • Choosing unnecessary links.
  • Insert one link into the squeeze and fix it with a retainer.
  • We start to rotate the crank and squeeze out the pin.
  • It does not need to be squeezed out to the end.
  • The formula of the movement will be as follows: tight move. easy. hard again.
  • Disconnect the chain, leaving the pin on the plate.
  • We count the links and dismantle them.
  • The chain is connected in reverse order.
  • Press in the pin.
  • We carefully evaluate our work.

There is a situation where the chain is stretched so much that removing the links does not have a sufficient effect. In this case, it is better to purchase a new product.

What types of bicycle chains are found

All types of bicycles, regardless of their purpose, use the same chain design. Such a product is a single-row roller chain with a clearly marked pitch. 12.7 millimeters. In this case, a separate link includes:

  • outer plates;
  • internal elements;
  • pins;
  • rollers;
  • videos.

The main difference between the chains is based on whether the speed is great or not. The number of speed modes determines the availability of suitable sprockets. This, in turn, affects the width of the bike chain. Also, a characteristic variety will be the presence of a specific lock or its absence. It serves to make it easy to dismantle the chain and reinstall it.

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.

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 you carry 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 immerse the chain in 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 keep it for several days. Next, 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.

How to properly tension the chain on a bike?

Every bicycle owner must be able not only to move around on it, but also to take proper care of it, providing repair actions if necessary. Chain problems can arise at any time, regardless of the price and type of bike.

In order to diagnose the problem in time, you should know the basic rules and nuances of replacing circuits. These rules are necessary for all drivers, because a person’s life depends on the condition of the vehicle.

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:

Fitting rear wheel and adjusting chain tension on a track or fixed gear bike

  • 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.

Slippage is a result of a transmission defect.

Part slippage occurs when the tension is weak. And the very weakness is the result 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 is worn out cannot be restored.

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

Replacement

Sometimes you have to resort to a complete replacement. To do this, the old one will need to be removed, and the new one installed.

    To remove the old chain, you will need to use a special tool. squeeze.

Maintenance

During walks in inclement weather, water and dirt accumulate on the transmission elements, and if these components and systems are not serviced immediately after returning home, then natural abrasive and rust will quickly disable them. Corrosion is the inevitable consequence of neglecting the chain, its sworn enemy. Too intensive care is also contraindicated. grease (grease) binds particles of dirt and dust, which leads to accelerated abrasion of stars and subsequent malfunctions.

How to chain a bike at speeds

How to chain tighten on a speed bike?

How can this be done? To begin with, it is reasonable to simply understand whether it is necessary to engage in tensioning the chain on a bicycle or change it, since this step is important for adequate work great. There are several signs to determine the need for this work. If, when moving, it began to rattle and jump off a little and now and then slips, then this is the first sign that it requires a new tension or it needs to be shortened. If you visually notice that the part of the bike began to sag more than usual (since the chain is not stretched all the way, then it should have a slight sag, but if the length has increased noticeably, it means that it has stretched and needs to be pulled or changed). If on a speed bike it has become difficult to adjust the gearshift settings. And when you clearly understand that it’s time to clean the chain.

Diagnostics

First you need to figure out whether the mechanism needs to be tightened? On ordinary bikes, it is not difficult to understand everything. 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 by no more than 10-15 mm, then there is no need to pull up).
  • If the tension of the bicycle chain does not lower it below 5 mm, it is necessary to immediately loosen.

Important! If the chain is loosened, it can fly off. If tight, it will be difficult to pedal.

Loose chain tension

On regular road bikes, the chain is not that difficult to tighten. To do this, remove the rear wheel and pull it back in the fork. The main thing here is not to overdo it and not to overtighten. Loosely taut and taut. are equally problematic when driving, so it is important to stop in time to keep the chain at 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. ensure that the length of the chain is the same as it was originally. In this procedure, the most important thing is to re-fasten the links with such a reliable lock so that it is firmly held, because even stretched is better than suddenly torn when moving. If you are not sure that you can re-fasten the chain, then it is better not to take this step.

Adjustment on speed bikes

How to tighten the chain on a bike at speeds such as a mountain bike? For a high-speed bike, if tightening the links in the first two methods did not give the desired result, then you can try two other methods.

The first method only works for high-speed bicycles that have already traveled with a weakened spring, that is, with an old derailleur. On a new one, you simply cannot do it manually. First step. remove the links from the gears. Next, knock off the stopper on the switch and rotate the switch in the direction of greater spring tension.

The second method of chain tensioning on a bike at speeds is not difficult at all, but sometimes it works. In order for the system to work efficiently, it is sometimes sufficient to simply tighten the derailleur cable.

Replacement

Sometimes you have to resort to a complete replacement. To do this, the old one will need to be removed, and the new one installed.

  • To remove the old chain, you will need to use a special tool. squeeze. Having set the squeeze of the chain opposite any roller, they begin to tighten the screw so as to squeeze out the pin. Then the tool is loosened and removed. The device is also removed with the help of a squeeze in order to regularly clean.

For replacement, you need a chain with the same number of links as the old, but shorter. To tighten, carefully place it on the gears and the derailleur in the same position as in the previous position of the links. Carefully fitting the rollers onto the gears, leave the two teeth open at the bottom. This step will make sure that the installation of the new one went right. Use the squeeze again to re-install the new pin. Both ends of the chain fit into the tool cavity to form a hole for the pin to be pulled out. Place your finger against the hole and gently, without haste, tighten.

Last step. installation in place of the pin. Make sure the pin goes in smoothly and easily. If resistance is felt, it means that both ends are incorrectly set and this needs to be changed. When installed correctly, the pin should fit snugly inside the roller, but it will not be difficult to place it.

Quite often, cyclists use a lock to quickly change or remove and clean the chain. On the one hand, this is convenient as it allows you to quickly remove the chain with a lock, on the other hand, it is better to leave a new chain intact at least until the start of regular suspenders, when it becomes clear how much more convenient it will be to use a replacement with a lock. Many cyclists have prejudices about the lock, as the chain supposedly breaks with it more often. There is no reliable data, but the new chain looks more reliable for most without a lock.

Do not forget that for a safe ride, you need to carefully monitor the operation of the bike and promptly eliminate all technical problems and change worn parts.

Types of bicycle chains

For single speed bicycles

Such chains are installed on city, children’s and teenage bicycles, as well as on vehicles with a sleeve. This type is characterized by the presence of one sprocket on the rear wheel and a gearshift in the rear hub.

Proper use and care of the components allows them to last a long time without wearing out. This is due to the fact that the mechanism looks like a straight line, so it is not subjected to unnecessary stress. These types are made from hardened, hard and thick plates that are pre-heat treated.

The single-speed links hold the mechanism more tightly, because of this, the load is distributed more evenly. This property allows the links not to stretch.

For multi-speed bikes

Such a mechanism is relevant in transport with gear shifting. The main difference is the presence of a gap between the component parts of the link. This factor allows the chain to move sideways. The design is characterized by a smaller width.

Misalignment is often diagnosed in such chains, this affects the convenience of bike control, and also leads to frequent wear of transmission parts.

Design includes internal and external links.

The structure includes hollow pins and plate perforation. They differ from conventional mechanisms in lighter weight, higher cost along with low strength.

Suitable for racing bikes where model weight is important.

With one repeating link

It is commonly called. Halflink. The difference from other models is that the links have the same structure and size, there is no division into internal and external. The advantage of the Halflink is that it is easy to dismantle, you can adjust the length and remove unnecessary links. This model is more prone to damage and stretching.

Adjusting the bike with speeds

The amount of chain tension on a bike with a rear parallelogram derailleur is determined 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 slack, 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 cause accelerated wear of the transmission parts. This primarily applies to two-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 on it, pushing the rear derailleur all the way forward. Now it only remains to add two links, and the optimal length will be determined.
  • Place the chain on the front of the largest sprocket and on the back of the smallest sprocket. Pull up the chain until the rear derailleur frame points straight down, more precisely, when the derailleur roller axles become one vertical line.

On double suspensions, it will be more correct to adjust the chain length by pressing the rear swingarm down 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.

Tensioning the bike chain

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.

How to chain a speed bike will help the following video.

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 is for pressing it in. A mounting location farther from the pressure screw is for ripping the chain pins. You can learn more about using such a tool in the following video.
