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.

Option one. Right

This option is suitable for those who have a well-prepared and properly stored bike. So, let’s begin. You have a bicycle that was washed in the fall, the wheels were lowered, the cables of the switches and brakes were loosened, the chain was removed from it and stored in a bag, and it also hibernated in a dry room.

To begin with, just wipe it with a slightly damp cloth, remove the accumulated dust that can get on the mechanisms, besides, it’s just more pleasant to work with a clean and shiny bike. Next, we make a small plan of what we need to do:

  • Tidy up and put on the chain.
  • Check and tighten all tightening and securing bolts.
  • Check the wheels in the “combat position”.
  • Adjust and adjust the brakes.

How to tension and adjust a bicycle chain

Adjusting the rear derailleur (Shimano, SRAM) is easier than you think. It will take about 15-20 minutes if you take your time. Read longer than adjust

Check before departure

Every time, going to ride a bike, it is necessary to check the serviceability of the vehicle.

Slippage is the 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 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.

Mountain & Hybrid Chain Length

1 way. Place the chain on the largest chainrings on your bike (large front and large rear), pull the rear derailleur foot as far as possible to move it forward. this is your optimal chain length. You should get it so that the body of the switch lies almost on the same straight line with the foot (this is the limit, further. breakage). It will be correct to set the foot at a slight angle, as in

If you make a mistake and make the chain shorter than necessary, then in the event of an accidental inclusion of the two largest stars in the system, the length will not be enough, and the switch will tear off to hell.

Method 2. The same as the first method, only we throw the chain onto the largest sprockets without using the rear derailleur and remember the desired chain length, after which we add 2 more links to this length and get the ideal length. In theory, you should get about the same as in method number 1.

A chain link is a chain element, a distance that is limited by two pins (axes) of the chain.

Method 3. Place the chain on the smallest sprocket at the back and the largest at the front, and adjust the chain length so that the derailleur foot is perpendicular to the ground, i.e. the roller axles of the switch were under each other.

Attention! If you have a double suspension, then it is necessary to measure the length of the chain in this position of the rear shock absorber, when the driven stars are as far as possible from the carriage (when the shock absorber is compressed).

How to adjust the chain on a speedy bike view.

A mountain, road or other type of bicycle that uses in its mechanism the ability to move the chain from star to star, requires a separate method of chain tension. In such a two-wheeled mechanism, there is no 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 chain with respect to sagging. This can be done in two ways.

We set the speed to the maximum front chainring and the same rear. In the area of ​​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 that directs and the one that pulls the rear cross-over must be aligned along the axis and be perpendicular to the surface of the earth.

The pull-up process consists in removing the links that turned out to be superfluous. 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 chain tensioner is mounted next to the rear derailleur. The simple 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 itself 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 purchase of a tensioner is necessary in order not to get into a difficult situation while traveling.

How to properly tension the chain on a bicycle if necessary?

Every self-respecting bike enthusiast should know how to properly tighten the chain on a bicycle and how to adjust it, since it is it that determines the quality of the ride. The article provides general guidelines for setting up a bicycle chain with both no gears and a high-speed.

The most important element in the design of both children’s and adult professional bicycles is the chain, which determines the ride quality, ride smoothness and smooth gear shifting. Before you tension the chain on the bike, you need to make sure that its length is chosen correctly: in the normal state, the chain can be in a slightly free state, sagging by 3 mm, but not more. In general, the question of how to properly tension the chain on a bicycle is always relevant, since it is part of the mechanism that determines the movement and will often require maintenance due to the large number of rubbing parts. You can check the tension of the chain as follows: press it with your finger approximately in the middle (opposite the outer radius of the rear wheel) and measure the amount of slack. If it is more than 1.5 cm, the chain must be tightened.

So, to tighten the chain on a bike that has only one gear, you must first turn it upside down, placing it on the seat and steering column. Next, you need to loosen the rear wheel fasteners (in most cases, the wheel is fastened with eccentrics or nuts), but not completely remove it. Then you need to find a special adjustment groove, which is called a dropout (from the English ” drop out ”. to lower), and move the wheel to one side or the other. After the required chain length is selected, the wheel should be fixed back, making sure that the plane of the wheel axis is parallel to the plane of the carriage shaft (this will prevent the development of the “figure eight”). It is important to know that it makes no sense to tighten the chain too tightly for two reasons: firstly, it is very difficult to pedal when the chain is too tight, and secondly, the complete wear of the chain elements occurs much faster.

It is necessary to know how to tighten a chain on a bicycle of a conventional design without gears, but at the same time you should be able to remove unnecessary links from the chain, since there is often a situation when the wheel has nowhere to move in the groove, and the chain still sags. In this case, you will need a special tool. a squeeze, with the help of which the roller is removed on the weakened chain and two adjacent.

How to Tighten Bike Chain | Single speed and Internal Gear Bikes

It is somewhat easier to tension the chain on a bicycle with gears, since it is partially regulated by a parallelogram switch (the gear shifting itself is based on the principle of adjusting the length and stiffness of the chain), however, even the mechanics will not be able to compensate for a chain that is too long, as a result of which problems with the movement of the bicycle at medium speeds may occur. To start adjusting the chain length on a bicycle with gears, you must also set it up with the wheels, then switch to the largest sprocket both front and rear, thus determining the top gears.

After that, the rear derailleur should be taken as far forward as possible by the chain, and the chain on the shifting system (where the pedals are) should also be taken slightly forward in order to determine the optimal chain length. Then the chain is released and carefully put on the special teeth. The idea is that after a complete run of the chain, the mechanical switch will use the rollers to pick up the normal position. It, of course, if desired, can be firmly fixed in one state or another, but in this case, switching will be impossible. After such a rough adjustment, you should proceed to a finer one, setting the chain at the pedals to the largest sprocket, and at the rear wheel to the smallest. For the chain, it is worth finding such a position in which the axes of the switch rollers, if not connected in one vertical line, are at least close to this.

Break of the chain

If you switch the speed at the moment of load, for example, when climbing a mountain, a chain break is likely. When a chain break occurs, the link is often riveted or broken. If riveting occurs, you can try riveting the link again. 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 the bike chain is a simple job. It is enough to pull back the rear derailleur itself on the weakened chain and put it directly on the front sprocket.

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 optimal sag and tension of the bike chain. You need to move the wheel along the grooves. The mechanism is fastened only in a parallel position of the axis relative to the carriage shaft. The correct slack is 5 mm. When tightening the chain, there is a difficult rotation of the pedals. Insufficient tension will cause the mechanism to kick off. Sometimes there is a tight stop of the wheel in the edges of the grooves and the extra links are removed.

Reasons for the chain rally

The mechanism fails in two cases:

tighten, chain, bike
  • Bending of a star on the system (front group of stars). In this case, it is possible to drive at a different speed, where there is no bent star. When using all speeds, it is strongly recommended to replace the damaged part soon. In a collapsible system, only one bent star is replaced. Continuous system assumes complete replacement of the system along with the connecting rod.
  • With incorrectly set speeds. After making sure that the connecting rods are in good working order, it is advisable to tune the speeds. The high-speed derailleurs (front and rear) are supplemented at the top with adjusting bolts to prevent over-the-top transmission. If the adjustment is incorrect, there is a high likelihood of chain failure. If the mechanism flew off the main large sprocket, the L-bolt is screwed in (low implies easy transmission). It is screwed in to the parallel position of the stars on the switch of a relatively large star. By analogy, in reverse order from the smallest sprocket, the H-bolt (high. high gear) is screwed in to the parallel line of the 7th speed switch.

If the front part of the chain with a small chain sags, the L-bolt should be tightened to the bike frame, the correct adjustment of which directly depends on the setting of the minimum speed on the bike. Screwing in continues until the distance from the inner chain of the derailleur to the chain is reduced to 1 mm. In case of serious damage and excessive wear, the chain must be replaced.

Provided that the chain falls off a large sprocket, the H-bolt is screwed in, the adjustment of which is supposed to be at the highest speed. Tightens up to 1 mm distance from chain to outer frame of derailleur.

Tensioning the bike chain

Method 1

Bend the bicycle spoke with a spiral and place it on the transmission. It is necessary for the spiral to pull back on the bike chain. This is an old and uncomplicated method, where the soothing does not look very aesthetically pleasing.
