The bicycle chain is one of the main bike knots. Many leads to a stupor question how to pull the chain on a high-speed bike? Special skills and availability of a special tool for this operation is not required. Actions can be performed independently, sufficiently follow the instructions.

Causes of the tear or gap

One of the main parts of the bike is a chain. But even with normal ride, it can fly or break. The main causes of breakage:

1. Damage to one of the stars Gearboxes. Speed \u200b\u200bbike gear systems are divided into collapsible and unintended. The replacement of the star is possible in the collapsible system. The unintended gear system is changed completely complete. If one star is damaged, ride is possible at speeds that remained serviceable.
2. Incorrect speed setup. Front and rear speed switches have special bolts that regulate the transmission. If these bolts, then the probability appears that when switching gear, the chain flies.

Tie a bicycle

The mechanism is possible to pull on its own, both on high-speed models with shifting and bicycles without them.

In order to correctly pull the chain by bike, especially if it will need wrench (which usually come complete with vehicle) And some patience.

On bicycles without speeds

Before working with this element of an ordinary bike, which differs from others, should be aware of the main rule - you can not pull the chain to the status of the string. The normal state of this node is considered to be a saving to 5 mm.

How to pull the chain on conventional bike, sequence of operations:

1. The vehicle is turned over. In order not to damage the seat or the surface of the steering wheel, you can enjoy small pieces of soft material.
2. The rear wheel holds on two nuts. To work with the chain, they must be loosen.
3. The consequence of the movement of the wheel on inclined grooves, you need to configure the required sagging.
4. After the recommended distance of 5 mm was reached, the rear wheel must be fixed on 2 nuts, which then should be neatly tightened. Do not apply a lot of effort.
5. Too stretched mechanism will not give the cyclist freely rotate the pedals. Also, when the transport return is returned to the original state, carefully monitor the wheel axis takes place parallel to the carriage shaft.

On high-speed with gears

How to pull the chain on? The design of the high-speed provides the tension of the link element by increasing the rigidity of the rear switch spring. In the case of incorrect selection of the length of the link element and the subsequent replacement, the switch will not provide proper tension.

With a strong savage, the chain will beat on the frame, and gear shifting will become difficult. Also, one should not put too short mechanism, the tension will accelerate the wear of the entire speed mechanism.

Important! Sometimes when installing a new chain on speed \u200b\u200bbike You need to shorten its length, remove the unnecessary links.

This can be done in two ways:

1. We stretch the chain to the largest front and rear sprockets. I pull for it, reducing the rear switch to the maximum forward. Add two levels and get optimum length chains.
2. Ride the chain in front of the biggest star, behind - the smallest one. Pull it up to such a position when:
   • the rear reproot frame will indicate smoothly down;
   • switch rollers must be in one vertical line.

How can you shorten the chain?

Chains of ordinary unscrewed bikes collapsible. One of the links has a special castle. Its opening will allow you to remove extra links or add new ones.
Important! Before proceeding to remove the unnecessary links of the all-wheeling chain on the high-speed bike, a special squeezing is purchased.

With it, you can carefully split the locations of the clamps, leave their necessary quantity, and then ropping.

There is another way to solve: in the absence of the tool, the pins on the links are scolded using emery paper. After that they are removed.

How to pick up and install chain calm

Soothing is simple designMetal manufactured from high quality metal that prevents the link element. To properly function, it is necessary to correctly install.

The procedure for installing the sedator:

• rent from bicycle stars shifting gear. In some models, you must remove the carriage;
• the largest star, the place of which rockling will take, must be installed in the middle place;
• secure the design at the locations of the cartridges;
• lubricate all rubbing elements;
• take the chain and pull it right.

Important! Soothing should be put forward to the star so that it does not interfere with the free work of the entire gear shift system.

Following the instructions described above, you can understand how to sports bike Tighten the chain or make the same operation on a simpler two-wheeled transport.

Sooner or later, every avid cyclist fails. Fortunately, there is no need to give a bike for repairs to an expensive workshop if you can fix the situation yourself. The following tips will help you in the shortest possible time to eliminate the problem.

Steps

Replacing a broken chain

Evaluate the breakdown and try to do something. If the chain broke while driving, swing the bike to the sideline, and put it on the side, asterisks up. Inspect the location of the chain break - most likely the chain hangs on an asterisk, and you can easily find two torn end. In the usual chain of the links, they are connected to each other through a pin (pin, or a cylindrical glass), fastening the inside plate, through which the pin and the roller located on top of the glass passes. Therefore, if you are an experienced cyclist, and bring a tool for mounting a chain and spare parts, you can independently fix the chain and pull it again (see method 2). Mostly, cycling chains divided into three categories:

• Chains with special rivets. With such chains, special rivets are supplied from the manufacturer. If you do not have such rivets with you, then, for the repair of the chain, you will have to get to the nearest bike shopping store.
• Chains with closing links. In such chains there is a special link with two rivets, which connect the ends of the chain. If this connection is breaking, then you will have to replace this link.
• Chains with "Normal" links. Old, traditional chains consist of standard links, each of which can be replaced by the same (if you have a tool).

Remove the broken chain. If you understand that it will be easier to replace the chain than to repair, then the first thing you need to do is remove the old chain. If she broke in full, just scroll through the pedals, and she herself subsides from the asterisk. If the circuit does not fall when scrolling, then it must be separated manually. This can be done using a squeeze, available in almost any cymagazine.

• Chain link connector with squeezing: Position chain chain opposite pin pin. Then tighten the pin of the pin, squeezing the PIN. If you plan to use the chain again, do not remove the PIN completely, but only to the level sufficient to separate the links of the chain.
• After you disconnect the chain, scroll through the pedals to sleep with the cassette. If you want to replace the chain, do not forget to calculate the number of links in the old chain (in bicycles with a rear switch, take into account the error). Also consider the type of your transmission, as it defines the type of chain suitable for your bike. For example, a chain for 9 speeds is suitable for transmissions with 9 speeds, etc.

Lift the rear wheel. The next step is to make a new chain through the rear switch. To do this, you will need to scroll the rear wheel, what will be done much easier if it does not stand on Earth. If you have a bike rack, or a pin in the wall that you can hang a bike, take advantage of this. If you don't have such goods, just lift the back of the frame, putting something, for example, a box or a slag block under it.

Grind the chain in the rear switch. Most modern mountain bikes The rear switch is a spring system of mechanisms downward down, under the main rear sprocket. Chain Details through this mechanism requires special attentionSo it depends on the safety of the ride. Take the "Mom" (end of the chain without Pin) pre-selected in the size of the chain, and circle it around the lower tensioning roller, and then - around the top. If everything is done correctly, the chain will pass S-shaped. If S turned out to be uneven, perhaps the chain did not go into all the grooves of the rollers, or for something caught.

• A small metal ear can be located between the tension rollers of the rear switch. The chain should not touch him.
• For some bicycles, for example, "delay" (bicycles with fixed transmission), or bicycles with planetary bushings, there is no rear switcher. In such cases, just pull the chain on the asterisk and scroll through the pedal, as is advised in the next step.

Put the chain on the back cassette. On mountain biking, the rear cassette is a set of several stars attached to the rear wheel. After the chain of the progress through the switch, put it on the smallest star in the cassette. After making sure that the chain went securely through the switch and tightly lying on the asterisk, stretch it slightly.

Grind the chain into the front switcher. On most modern mountain bikes in the area of \u200b\u200bthe front asterisk, there is a metal mechanism moving chain from one sprocket to another. Swipe the front end of the chain through this switch. If the circuit does not get, shove the rear wheel a little further.

• From "Glumchah", again, no front switcherSo, just put on the chain on the front asterisk, as shown in the next step.

Put the chain on the front asterisk. Put the chain on the smallest front asterisk. Tense well, and check that it lay on all the stars' teeth, then scroll through the pedal.

Connect the ends of the chain. Now that the chain reliably passed through all the elements of the transmission, you can connect its ends, and enjoy the trips again. Place the link connected ("Mom" and "Pope") in the clip, on the stop, which is closer to the locking screw. By adjusting the position of the chain, move the pin to the clamping pine so that they are coaxial. Sit down with a locking screw. Rotating the handle, clamp the PIN in the link. Constantly control the degree of immersion of Pina. Failure to comply with this subtlety can cause breakage.

• There is one useful tool - a C-shaped bracket (a small slim piece of metal) that helps hold two end of the chain nearby. It greatly facilitates work, since you do not need to keep two end chains themselves. Such a C-shaped bracket can be a bent clip.

Replacing a weakened chain

1. Determine where the chain jumped out. Sometimes the chain is not broken, but just coming down from his usual position. Since in this case it is still in the front and rear switches, no special intervention will be required - everything you need to do is install the chain back to the asterisk. If the chain slept on the way, get off the bike, put it on the side, asteristers up, and find the place of the scope. Usually the chain falls from the front sprocket, but remains on both switches.

   • Look for places where the chain can shove. Take appropriate measures before the next trip.

2. Extrarich's lightness in case the chain appeared. As mentioned above, sometimes the chain is stuck between the rear asterisk and the frame. In this case, loosen the rear wheel eccentric and unscrew the eccentric nut so that the chain can be removed.

   • Eccentric opens by defering the small lever located in the center of the rear wheel. After that, unscrew the nut on the opposite side of the lever, and release the chain.
     • Do not forget to hold the eccentric back before the trip. The nut must be in moderate, so that the lever is clogged not too tight and not too weak. If the lever is clamped too tight, unscrew the nut slightly, and try to clamp again. If the lever is clamped too easy, the nut must be twisted.

3. Bicycles with rear switches should be loosen the tension of the chain, and pull it on the front asterisk. On most bicycles in the rear switch there is a spring that provides chain tension when driving. Overcoming the resistance of the spring, pull the chain so that it can be put on the smallest front asterisk. Then let go of the chain, and make sure it is stretched enough.

   • As a rule, now you can continue to drive. The first time the bike can go randidly until the chain is in the right position.

4. In bicycles without speeds, the chain is stretched on the front asterisk by scrolling the pedal. As mentioned above, in many bicycles, for example, there are no speed switches in the "muchahrices". In this case, put on the chain on the back asterisk, and, hooking her for the as much as possible of the teeth from the bottom on the front asterisk, scroll back the pedal. The chain should catch and start wreking on an asterisk. When the chain rolls on the last top of the sprocket, it can function normally.

   • Twist pedals will be easier if you raise the rear wheel. To do this, you can put a bike on the rack, or put any material under it. You can also ask someone to hold the rear wheel on the weight, or, as a last resort, simply turn the bike.

• There is nothing unusual that the chain of from time to time falls, but if it happens too often, the help of a specialist may be required.
• If you have such an opportunity, purchase a special tool called the chain tensioner. Buy yourself a couple, and follow the instructions on the package. As a rule, you will need a cruciform screwdriver and a universal wrench of a certain size. These tools will help you maintain the necessary chain tension.
• If your chain still saves, and you cannot seek help to a specialist, you may need to remove several chain links to shorten it. But, do not mind it, if you do not know how to relieve the links.
• Each cyclist must have basic knowledge and repair skills. So you can not only save on the service, but not to be in a hopeless position, being away from the bicycle system.

Cautions

• Take long hair, fuel clothing and fasten the width to the end before repairing the chain.
• It is better to use gloves when repaired, so as not to fall out in the lubricant.
• Do not drive your fingers into the chain, otherwise they can be injured, or lose at all.

The popularity of two-wheeled eco-friendly transport has no doubt. Special popularity acquired bicycles with speeds. But, the pleasure of driving is obtained if the bike rolls easily without making foreign sounds. Therefore, the question of how to adjust the speeds of cycling is correct relevant for many cyclists.

ARTICLETOC: Enabled \u003d YES)

After all, it is the inability to switch and configure them leads to the creation of emergency situations on the roads and injury. When buying a two-wheeled bike in the store, you can contact the seller, which will set the speeds, making safe your ride.

If you need to make the setting on your own, you need to read the instruction that is easy to find on the Internet, setting a specific model of the bike in the search bar.

The speed changes the cyclist depending on the situation, so the coin, the signal from which goes to the speed switch, throwing the chain to the rear sprocket of the bicycle, should be within its reach, i.e. On the frame or steering wheel.

There are two switches on the bike: one is installed in front, the other is rear. Their task also includes maintaining the optimal tension of the chain. The switch resembles a parallelogram having springs and rollers that serve for the chain guides.

It is installed on the bicycle frame, and holds its device, called the "rooster" - a metal holder that does not allow the switch damage.

Directly involved in choosing a cassette transmission or a rear set of cycling transmission, which consists of gear wheels of different diameters installed by the rear wheel.

There is also a front transmission set, which is also consisting of gears, differing in diameter. It is attached with rods holding the pedals necessary for the transmission drive, on the axis of the bicycle (in the front of the frame).

When do you need to spend speed setting?

There are three such cases:

• if the cable is stretched or span, the transfer of commands from the coin is broken and the need to configure;
• the wear of the return spring located on the cassette leads to the execution of functions not in full (failure when switching speed, etc.);
• the deformation of the "rooster" or switch arising from aggressive ride.

Trouble-shooting

To switch the speed of the bike has always been effective, the switch and the cable should be in good condition, on which the work of the latter depends on.

Tighten the cable using the drum located on the coin. To the cable worked properly, it periodically needs to be lubricated. The chain with gear wheels also need lubrication so that when riding a bike, extraneous noises occur to ensure easy switching and reduce friction.

Determine the state of the "rooster" can be visually or using a special instrument. It is easy to repair or replace, checking whether the switch has not been deformed who has the most weak place It is considered parallelogram.

During the operation of the bicycle, it is possible to fail the screw adjusting the chain tension.

What instruments need to configure the speed of the bike?

Usually, all of them come in a set with a bike: Passed, screwdriver, a set of hex keys or horn.

What you need to know about setting up?

Setting the speeds on the bike begins with adjusting the height and angle of the front switch, which touch the gears should not, how to defend them away from them. It is correctly fixed, if it is 3 millimeters above the gentle of the largest wheel. Adjust the angle, means that the switch must be installed parallel to the rotation of the wheels.

The following bolts are used to set up gear shift:

Putting a chain to the leftmost position, disconnect the cable by unscrewing the nut that hold it or bolt. After that, go to adjust the gear, seeking to be on one straight line, for which the bolt is screwed (with the "High" or "H" labeling) indicated in the picture. After completing the adjustment, we again tighten the locking cable with a screw.

For further settings put in extreme right position chain, i.e. At the biggest rear and the smallest star in front). The gears are adjustable with a "Low" or "L" bolt until the position is on the same line.

That is, at the first stage, the setting maximum speedUsing the screw and the smallest gear wheel indicated by the letter "H", trying the wheel and the switch of the switch parallel.

In the next step, we set up the largest gear wheel, corresponding to the smallest speed. To do this, we twist the screw on the switch marked with the letter "L", again trying to position the roller parallel and this is the wheel.

Then you need to set the position that will correspond to the highest speed.

Next, regulate the rear gear switch, for which it is for a small gear wheel and the largest rear chain. Scrolling the pedals back, regulating the tension of the chain with a screw, supply the upper roller (as far as possible) to the gear wheel. It is necessary that the gear shift is smooth.

After the installation switch is properly installed, you can continue the setting. Now we will put it on a large back asterisk and a small front.

Available in 1 mm, between frame and chain. For this, the pre-cable of the control control of the screw L, then, is fixed with the screw.

Finally, we turn to the exact setting by transferring the chain into the middle position on both stars. Use the screw allocated in the photo. Both gears should be in the same plane.

Important: When building stars in one line in several millimeters, the deviation is allowed. But because of this, the transmissions are worse. Review all flaws will help the test runoff.

How to configure correct forward gearbox?

Conduct the adjustment by analogy with the adjustment of the rear switching with a metal limiter and two bolts shown in the photo below.

The final gear setting is carried out on the front switch when the chain in front is on a large gear wheel, and on a small rear. This operation is carried out with screw N, while between the chain and the frame will not achieve a distance of 1 mm.

Test ride will tell you whether the setting is done correctly.

If the switching is difficult at low speed, the cable adjustment on the front switch is needed. If the chain is seriously moving to a large wheel - adjusting the cable tension on the same regulator.

How to set up a transfer on a mountain bike?

Setting up in five stages. If you need to configure both switches, it is recommended to start with the rear. Initially, you need to make sure that the cable is good. In the second step, inspection of the tensioner of the chain, which must be installed strictly parallel with the stars of the cassette.

This is achieved by tensioning the switch. When the requirements are executed, go to setting gear. The chain is placed on the smallest star, put the highest speed, after which the High screw is achieved so that the little star show the mark of the switch roller.

In the next step, the smallest speed is fixed, for which, by setting a large, turn the screw, while the video becomes with a large star. The chain at the same time is on the largest asterisk. Well tighten the bolt.

If the bike has a digital scoreboard, the tension of the cable can be adjusted when driving. Otherwise, the correctness of the adjustment is determined by the experimental way, performing control riding. With a difficult speed set, the cable must be loosen, with its difficult decline - pull it out.

Finally, the step is the fifth - adjustment of smooth gear shift. Putting a chain on a small star in front and at the big back, turn the pedals, bringing closer roller and an asterisk. This is completed on this.

Video: Setting the speeds by bike

All cyclists are sooner or later faced with the need to remove and subsequent installation of the chain by bike, which has a gear selection function. Such a procedure is necessary for periodic cleaning and lubrication chain, repair workassociated with the rear wheel or to directly replace the chain itself when it worked out its resource. Despite the fact that this operation is relatively simple, a number of questions may arise from beginner cyclists.

Since the chain from the bicycle has already been removed, then, most likely, you already know what type of chain is equipped with a cloth or solid chains, and also possess necessary tool, Namely, special squeezing, to work with solid type chains.
How to put a chain on a high-speed bike
Speed \u200b\u200bbike, unlike Singlespid, requires a slightly different algorithm for action.

After installing the chain on a high-speed bike, it is necessary to check the correctness of its installation. To do this, scroll through the pedals and try switching the front and reverse gears. If any jams are not observed and extraneous sounds - it means the circuit is set correctly.

How often it is necessary to clean and lubricate the chain
Clean the chain with removing it from the bike and lubricate it is recommended approximately every 100-150 km of run. At the same time, it should be noted that this recommendation is valid only when proper use different types lubricants in accordance with weather conditions. If for any reason you put a lubricant for wet weather and ride a bike in dry weather, then the likely probability is that it pollutes dust significantly faster.

It should also be noted that there are special deviceswhich allow cleaning the chain without removing it from the bike.

When the chain needs to be replaced
To determine the degree of wear of the chain, it is necessary to measure the distance between 24 pins (axes) of the chain using a caliper. The permissible distance value ranges from 304.8 to 306.4 mm. If the distance exceeded the upper border, the circuit must be replaced.

For more uniform wear of the bicycle transmission, experienced cyclists advise to have a set of three chains and periodically alternate them in their work on your bike.

At the end of the article we offer to your attention seen, which demonstrates the entire process of installing the chain on a high-speed bike.

Or to replace when it is already.

How to remove the chain from the bike

With a lock

To remove the chain you need to reveal the lock. There are several types of locks, but the opening processes are similar, for this you need to close the axis of the lock and remove the lid.

If problems occur when you open the locks, you can use tools, such as special pliers for opening locks.

Without a castle

If a bike is a chain without a lock, then you will have to press the axis from the chain link. Also, this process will need to be carried out in order to reduce the number of chain links when it is necessary.

For the reasons for the axis of the chain, you need a special tool - squeeze chains. For this operation, you can choose any link chain, the only condition, when re-extracting it is better to use a new one, since after the operation, the link is slightly loosened.

Insert the chain link into the tool and secure the screw. Note that in some chain screenings there are two seats, one place to press the axis (it is closer to the locking screw), and the second place is used only to adjust the axis. Watch carefully scinting screw, thereby squeezing the axis.

Do not extrude the axis to the end if you plan to assemble the link with the same axis, otherwise it will be problematic to establish it back!

The chain is removed.

How to install a chain on a bike

Before installing the chain you need to make sure that it is suitable for your bike. Complete with a chain is usually sold special axis, with a pointed end. It serves to facilitate the installation, after pressing the axis, this end must be broken with pliers. Also, the axis can already be installed in place, in the case when the chain is supplied without a special axis.

To install the circuit, move the speed switches on small stars. Then grind the circuit through the tensioning frame of the switch, do not confuse the directions, the bottom roller circuit runs on the left, and the top right.

Connect open links, install the axis. We insert the link in the squeeze chain and fix the locking screw. The rotation of the squeezing chain handle is inserted into the place, it must be equal to the edges of the chain. Remove the squeeze chain, choose the end of the axis if necessary.

Check for this chain link freely, if it runs tight, then it is necessary to adjust the screening axis. Insert the link in this case to the second seaside seat, then you can see both ends of the axis.

The chain is installed.
