HOW TO CHANGE SPEEDS on a bike?
Any cyclist should know how to switch gears on a bicycle and how to set them. Just Stick to some simple rules to make your cycling comfortable and efficient. Plus, your derailleurs will last you longer and save you money.
When we were small, there was no trace of speed on the bike, and no one thought about it. We just pedaled and the bike just moved. But today the simplest model of a bicycle is necessarily equipped with a certain number of speeds and has two brakes. At the same time, many people think they know how to switch speeds on a bicycle. But, in fact, it is not as easy as it seems at first glance.
ADJUSTING THE FORWARD SPEEDS OF THE BIKE
You need to adjust the forward speeds in about the same way, there is nothing difficult there, and you can figure it out at the level of intuition, therefore, we will consider only some points. The chain moves along the front sprocket with a stop made of metal, which can be adjusted with two bolts. The principle is the same, so, as mentioned earlier, there is nothing complicated about it. And, again, so that it does not suffer with the setting again, switch the speeds correctly, as described above.
Correct gear shifting is determined by one main rule, the observance of which is very important. when driving, you need to make sure that the chain does NOT warp. This can happen if the chain is engaged at opposite extreme positions of the chainrings and chainrings. With this arrangement of the chain, it clings to all possible and impossible obstacles, is exposed to uneven loading and wears out much faster.
Here are some tips to help you switch gears correctly:
- Better not switch gears when driving downhill. The first thing that will happen to you is the loss of your riding rhythm, which will affect your stamina and movement speed, respectively. This is also not worth doing, since when going uphill, the voltage of the chain is already quite high, and if, at the same time, you are engaged in throwing the chain between the stars. Such actions will adversely affect the resource of parts, and, soon, a breakdown may follow. So you need to switch gears before lifting, at the moment of the greatest relaxation of the chain.
- A huge number of BIKE people rarely use the front derailleur on their bike. Why it happened so is difficult to answer, but, nevertheless, it is a fact. It is much more efficient to use forward gear when driving on a sloping road. One shift on the chainrings, in this case, will have more effect than two or three changes on the rear. Just put the chain in the back on the middle sprocket and switch in front of them.
- When a fairly serious descent is planned on your way, then, again, perform gear changes before starting to go down. This is due to the fact that when the process of driving downward begins, it is better not to be distracted from the brakes, and you will need to follow the road especially carefully, because falling on the descent is an unpleasant thing.
- Gear shifting should be smooth. There should be no rumbling, grinding, knocking and other extraneous sounds. If you follow this, then the gearshift system will serve you for a much longer time.
ADJUSTMENT and adjustment
Sooner or later, any cyclist begins to notice that the gearshift system emits extraneous sounds, such as crunching, rumbling, etc. It happens that during gear shifting the chain jumps a couple of sprockets or the opposite situation: you cannot switch to the required sprocket. So what’s the deal? You just do NOT have gear shifting configured. So how do you set your bike speeds? Let’s try to figure it out.
The gearshift setting may go astray because you are NOT familiar with the gearshift rules and is not changing gears correctly. Or your gearshift system is simply too dirty and needs to be flushed out. But the reasons are a separate conversation, and we will focus on setting.
We will NOT delve into the nuances of professional tuning. professional cyclists are unlikely to search for speed settings on the network. Therefore, let’s move on to the Quick Course on Speed Tuning:
- Fix your bike upside down (using a special stand or just put it on the handlebars and seat). The speed setting is carried out using the special bolts on the switch.
- Now you need to set the chain in the leftmost positions (on the large chainring and small rear). After that, Unscrew the part that serves to fix the cable to completely unhook the cable.
- Now, tightening one of the bolts on the speed switch, you need to adjust the two gears so that they are opposite one another. You will recognize which torque bolt by the “H” or “High” mark next to it. What does High speed mean?
- After that, we install the chain in the rightmost positions of both stars (on the largest rear and smallest in front). We again adjust the gears with the second screw, which is marked “L” or “Low”. Putting the stars in one line.
- Now, you need to install the chain on the middle sprockets in the front and rear and adjust the gear shifting as precisely as possible using a screw, which is called “lambs” and the cable floor is located directly. It must be remembered that our goal is to ensure that the middle gears are opposite one another. Before you start twisting the “lamb”, it is better to perform a test drive, which will give an idea of how difficult it is to switch or, conversely, too easy.
However, the shifter is a kind of “heart” of the transmission system and, for the most part, it is he who is responsible for the quality of gear shifting. Today, a limited number of companies are involved in the production of high-quality derailleurs, and the most popular among them is the Japanese giant. Shimano.
For the convenience of customers, all Shimano derailleurs are divided into groups. Let’s dwell on each of them in order:
- Shimano Tourney is the easiest derailleur for beginners. They are distinguished by their low cost and high reliability. Bicycles equipped with components of this class are designed for leisurely ride on the track or on densely packed soil. This Shimano derailleur cell needs constant adjustment and starts to malfunction if too much dirt gets on it. Fits Shimano 2300 Road Group.
- Shimano Altus / Acera is also the entry-level equipment. But Acera derailleurs are already installed on bicycles designed for use in sand and mud, naturally only at the amateur level. For those people who, for whatever reason, cannot purchase more expensive options and ride both on the ground and on the asphalt, this type of Shimano derailleur will suit perfectly. Fits Shimano Sora Road Group.
- Shimano Alivio. This group of equipment is something in between, it can not yet be called professional, but it is no longer amateur. Equipped with Alivio derailleurs, the bikes are great for both the trailblazer and the cycling adventurer. This Shimano derailleur group is reliable and unpretentious. The price-performance ratio in this group of switches is implemented most successfully. Fits Shimano Tiagra Road Group.
- Shimano Deore is a professional line of derailleurs, but if you look at things soberly, the differences from the Alivio are not that great. All that changes is the indicators of lightness and reliability, they get a little better, but the price increases significantly. Fits Shimano 105 Road Group.
- Shimano Deore SLX and XT are lightweight and reliable professional equipment. The reliability of the Deore SLX / XT derailleurs is reflected in the cost: the price of the Shimano Alivio rear derailleur is about 45 and the Deore costs from 90 to 110 Ideal for professional athletes to train every day. Fits road groups. Shimano Ultegra and Ultegra Di2.
- Shimano Deore XTR is the Highest Category Racing Equipment. NOT afraid of any stress. Extremely expensive. Fits Shimano Dura-Ace Road Group.
Shimano makes derailleurs not only for mountain and road bikes. There are many derailleurs available for touring, city and adventure bikes. But we do not consider them, since these bicycles are NOT popular in the CIS.
The myth and truth about the ascent
The upper levers are one click toggle and do NOT require any pressure. Beginning cyclists are often frightened by the fact that it is categorically impossible to switch speeds when riding uphill, but this is not so. The rules for shifting uphill are very simple: If you need to reduce the speed on the chainrings, then you should slow down the torque with the pedals, that is, the shifting should be smooth.
Slowing down the torque with the pedals while shifting forward speeds follows after that the difference between the stars on the front transmission, as a rule, is about 10 teeth. This requires smooth shifting. Therefore, when moving uphill, or just on level ground, it is necessary to slow down the torque of the pedals. Then there will be a smooth and correct switching. If, when lifting, you need to add speeds on the rear transmission, then you should slightly increase the torque with the pedals. Knowing how to switch speeds on a bike correctly, you will significantly extend the life of your second two-wheeled.
What not to do on the rise
The only thing that you should definitely not do when going uphill is to increase the speed on the front sprockets, switch from first to second and from second to third. You can increase the speed from behind absolutely calmly, and not fear that something will happen to the bike.
If, after shifting the gears, you hear a clatter or other extraneous sounds, then this means that the shifting has not occurred, and it is necessary to squeeze the lever. Or the switches need to be set correctly. Proper gear shifting is best taught by personal experience. So ride, try, train. And then the question of gear shifting will not be difficult.
How to set your bike speeds so that all equipment works perfectly
Adjusting the rear derailleur. The chain needs to be translated into small stars. After releasing the cable, for this you need to Unscrew the bolt, which clamps it. After we find the screw, which is responsible for shifting the rear derailleur foot. It is marked with the letter “H”. With the help of a screwdriver, it must be shifted so that the gear on the cassette where the chain lies is in line with the stars on the rear derailleur. That is, lay in the same plane.
After that, we take the cable and pull it out as much as possible, then we fix it with a screw, as before we opened it. After fixing, we try how the rear derailleur works on the bike. If the chain is poorly transferred to larger stars, you need to tighten the cable. This is done using a special “lamb”, Located where this cable enters the derailleur, it looks like a nut with more convex edges. Steep it clockwise.
We put the chain on the big sprockets. This is done with a screw, marked with the letter “L”, change the position of the switch in order to shift the foot and put it in line with the large star located on the cassette.
Bike front derailleur
Let’s start setting up the front derailleur. To do this, in the front we put on small stars, in the back. To the big one. Take hex # 5 to loosen the screw holding the cable. Take a screwdriver and an adjusting screw marked with the letter “L”, move the frame. It must be placed so that there is a gap of 3-4 mm between the inner part and the chain. When the lower limit is set, we need to fasten the cable back. To do this, we tighten it with our fingers and in this position we fix it with a screw.
Moving on to setting up the second asterisk
The cable is fixed, the chain must be placed on the back on a small sprocket, and in the front it must be thrown over to the second. If the chain hits the frame, the cable must be tightened. We stretch it with “lamb”, it is located on the shifter on the left. You need to turn it as long as the chain stops touching the frame. After the gap between the frame and the chain is 3-4 mm, this means that the first two stars are adjusted.
A trick for better switch performance
There is one secret of how to properly shift the gears on a bike so that the chain and derailleurs wear out as little as possible. When the chain is at the extreme sprocket, you need to squeeze the switches, and not immediately release them. You need to press the lever and, when the chain has shifted to the desired gear, drive a second or two, holding it, and only then release it. With time, became more experienced, you will feel when to release the lever.
How to change speeds
You must switch speeds on the move, that is, you must pedal. You need to select speeds Not only based on the terrain and your physical capabilities, but also so that the chain does NOT distort. You can make sure that there are skews just by looking at the chain. If it moves parallel to the frames of the front derailleur, then the selected speed is optimal. Skew occurs when the chain at the front is large and the chainring is also large at the rear. That is, you need to evenly switch both on the cassette and on the crank chainrings. Extremes are undesirable here, unless they are on the bottom side.
How to switch speeds on a bike? How to adjust bike speeds
Many people buying a modern bicycle do not know how to use all its amenities. They are intimidated by all these cables, switches and a lot of different things. Naturally, they don’t know how to change the gears on the bike to make it easier to ride. However, if you delve into all this equipment and understand how it works, then the ride will become much more pleasant and comfortable. And fixing this or that node will become an exciting hobby.
For seasoned cyclists, gear shifting does NOT raise questions. But for beginners, it is worth explaining all the nuances associated with the question of how to switch speeds on a bicycle. Illiterate switching sooner or later can lead to an open circuit or even breakdown of switches. And if you are on a long trip, then it can seriously stagnate you by surprise. Competent gear shifting. This is not only a guarantee of the health of your bike, but also the most productive ride in any terrain.
To make everything clear, let’s consider the design of the bike. The left trigger coin is responsible for shifting forward speeds on the device. The right trigger coin responds to reverse gear shifting.
Setting up the third star
The original chain may interfere with the frame. To fix this, you need to move it away from the bike using the adjusting screw marked “H”. This will increase the space between the frame and the chain. After everything is set, the chain does not have to touch anything.
The setting of the switches is identical everywhere and there is no difference. The bike has 6 speeds or 32 gears. It’s just that six or eight-speed only have a rear derailleur. After all, they have one star on the rods. As a result, their design has one less component.
In this article, we discussed how to change the gears on a bike correctly, so that its components work properly and reliably, and also learned how to adjust gears. Both the back and the front, it’s not as difficult as it sounds. It is worth trying once, figuring it out, and then you can set up the equipment in a matter of minutes. Separately, it should be said about the chain lubrication, it must be specialized, in no case can the grease be used, it will kill the chain. So take good care of your bike and it will repay with great performance and ride comfort.
How to put a rear derailleur on a bike
Replacing the derailleur on a bicycle: a sequence of actions
- The replacement process begins with removing the old mechanism from the frame. To do this, by opening the chain link, unscrew and remove the old switch.
- Further to the “cock”, which is a protruding triangle with a hole, securing a new mechanism. It should be screwed on well, but not too tight.
- Then we install the chain on the smallest star so that the roller and the star are visually located on the same line.
- Carefully slide the derailleur towards the largest sprocket without holding onto the roller, which is easy to bend. Thus, you will be insured against the risk of the chain hitting the spokes.
- Using the adjusting screw, fix the position of the switch so that it still remains opposite the large star. If the mechanism hits the star, then you can lose the spokes, too much clamping is fraught with failure of the lower gear.
- Moving on to the cable. normally it should move freely in the shirt. It is necessary to check the absence of creases and the course itself. To do this, install the chain on a small star, pull the cable and fix it in a taut position.
- We check the operation of the mechanism. First of all, turn the pedals. there should be no Clicks in the process, and the gearshift up and down should be smooth, without jumping over the stars and without delays. At first, it is better to take a screwdriver on a bike ride. under load, the mechanism may need to be adjusted.
Regardless of the mechanism of which company you choose, sooner or later you will have to face preventive maintenance. After all, the rollers are consumables and wear out as the bike is used, so from time to time it is necessary to carry out their preventive replacement.
Many people think the rear derailleur is much easier to set up than the front derailleur. In both cases, you will have to make some effort, but this work will pay off with interest in comfort while riding. If you do NOT want to waste time installing the derailleur.

How to install a rear derailleur on a bike?
Having clocked many kilometers on a bicycle, I made sure that a branded derailleur is much more important for a comfortable ride than stylish grips or leather Brooks. But it’s not enough just to buy Shimano or Sram, the quality of installation and setup is important.
Preparatory operations for setting
All the guides written on how to set up the rear derailleur on your bike have tips on how to properly prepare your bike for this first step. The fact is that the speed switch is a rather thin device located in an inaccessible place. Before you begin to regulate it, it will be necessary to eliminate all the reasons that prevent the correct implementation of such a procedure.
Pay particular attention to the cleanliness of the bike and its SEPARATE structural elements. cassette with stars and the derailleur itself. You will also need to lubricate your bike chain. Such operations will allow you not to get dirty and clearly see the nodes that you have to adjust.
The next stage of the preparatory work will be the transfer of the bicycle chain so that it stands on the stars of the smallest diameter both in front and behind. To do this, you will need to find the adjusting screws located on the switch, which are labeled: H (high) and L (low). Their purpose is to adjust high and low range gears. Here you need a screw under the letter “L” Unscrew to the maximum value.
Before you start adjusting your bike, you need to clean and lubricate it.
After the screw has been unscrewed, it is necessary to turn the drum until it stops, moving clockwise. This cable tension drum is not installed on all models of modern bicycles. This is worth bearing in mind. A similar drum is usually placed on the shifter. It also turns in a similar way, while you will need to stop, and not screw it all the way around 4 turns.
One of the final steps in preparing the bike derailleur is to remove the screw that secures the cable directly to the derailleurs. If it is rusty and dirty, then it will have to be replaced. In the case when He is not too worn out, namely, it is not visible that he is unraveling, he will clean it and lubricate.
It will be necessary to check the ease of sliding of the cable through the “jacket”, which are plastic tubes mounted on the bike frame. The fact is that in most cases the gears shift poorly precisely because they are clogged with dirt. To prevent this from happening, “shirts” must be washed.
What is the rear derailleur made of?
The material of manufacture can be different: from stainless steel to titanium. On budget bicycles, as a rule, steel and plastic derailleurs are installed. such products are short-lived, work poorly. Models of the middle price segment are equipped with an aluminum mechanism, and the most expensive ones are composed of composite, carbon and titanium.
Rear Derailleur Setting Basics
In the event that you DO NOT have sufficient experience with a bicycle and DO NOT know how to adjust the rear derailleur on a bicycle, you will need to carefully study the instructions for your bike. Usually it is written in simple and understandable language, and you can figure it out without any help. If it is difficult for you to understand everything, you can contact the master, who has sufficient experience in adjusting this unit.
The very same adjustment procedure must be started by checking that the roller intended for tensioning the chain is located exactly above the small sprocket. If this position is not installed, it must be set using the adjusting screw marked with the letter “H” In order to move the roller to the left, you need to turn the screw clockwise, if you need to turn it to the right. counter.
After you are sure that the large gears are set correctly, you can begin to install the derailleur cable. To do this, it is necessary to thread it into the fastening screw. Further work is to tighten it harder with one hand, with the other tighten the screw itself, acting on the hexagon. If you are new to cycling and do NOT know how to adjust the rear derailleur on your bike, remember that the mounting screw must not be tightened to the maximum torque.
After the cable is installed, it is necessary to adjust the small gears. For this purpose, the chain is transferred to the rear sprocket of the largest diameter. After that, check the tensioner roller over the large sprocket, set it in this position with the screw under the letter “L”. It is configured in the same way as above.
If your derailleur has the ability to adjust the chain tension level, adjust it. After you are finished adjusting the derailleur, try shifting gears on your bike while moving. They should change quickly and easily. If you feel some difficulties, then adjust the device additionally using the cable tension drum.
Bicycle Rear Derailleur Setting
It will be best if you choose the optimal settings for yourself and remember them. In the future, you can set them, already knowing which position of the adjusting screws or the drum is optimal for you. This will make cycling easier and will significantly extend the life of your bike.
How to properly adjust the rear derailleur on a bike?
How to adjust the rear derailleur on a bike is a must for every cycling enthusiast. The thing is that the Named node of any bicycle is responsible for shifting gears to the VELOBIKE while driving. If it fails, normal operation will become impossible.
A bit of boring theory
The rear derailleur mechanism throws the chain over the cassette stars, allowing you to lower or higher gears (for reference, it was invented by the Italian Tullia Campagnolo back in 1950). This device also keeps the chain taut. There have been many varieties since the invention. A little about the main, most characteristic features.
- Manufacturing material. Here are steel to carbon fiber. The entry-level models are equipped with steel, and not always of good quality, and plastic. In the right hands, these switches even work sometimes. Models of the middle category in most cases are made with the introduction of aluminum. The most expensive models can boast not only precision in work, but also titanium, carbon fiber or composite.
- Frame size. In theory, everything is simple. the longer the frame, the more gears you can choose. However, one cannot say so categorically, since someone will prefer a short frame, and not afraid of stones, while others are interested in greater comfort in switching. And everyone is right in their own way.
You can still describe in detail the action of the spring or the options for the location of the cable for a long time. However, many good articles have been written on this topic. I will only note that there is not much difference from which side the cable enters the switch. So, now about the interesting.
Mountain Biking. How to adjust the rear derailleur
Every cycling enthusiast should know how to properly adjust the rear derailleur. If the mechanism fails, its normal operation will come down to comments. To many cyclists, the operation of the rear derailleur seems complicated and incomprehensible, hidden from prying eyes. The mechanism can easily and unpretentious perform its functions, but one day it will fail. If you are inexperienced in fixing a similar problem, take your bike to a workshop, where a qualified technician will fix the problem within a few minutes.
You can understand the principles of the rear derailleur. By adhering to our recommendations, you will say goodbye to the difficulties in the further maintenance of the bike on your own.
Although the gear shifters are simple at first glance, their optimal setting can seem like a daunting task. Gear shifting is a certain sequence of actions that loosen and tighten the cable. The cable without which the rear derailleur will not work. Tuning an old and worn-out movement or a cheap model made of low-quality metal is a big challenge. After just a couple of years of operation, play may form in the switch connections.
How the rear derailleur works?
For the efficiency of tuning, it is advisable to study the device of the component of interest to us. The key principle of operation is based on gear shifting when changing the chain from one drive sprocket to another, of a different diameter. Let’s start by comparing the front and rear derailleurs. Structurally, the front derailleur is a regular steel frame that moves in different directions. During movement, this chain shifts to the side, from one sprocket to the next.
The rear derailleur has a more complex mechanism. It has a special spring-loaded foot with small rollers. By dropping the chain onto smaller diameter sprockets, the cyclist uses a shifter to loosen the cable, thereby shifting the chain to the desired sprockets. For chain transfer to a larger sprocket, the shift process is slightly different. In this case, the cable is pulled, after which the foot brings the chain to the star of a larger diameter, friction arises in the grip of the tooth, which can be sent to a new gear.
Reasons for the failure of the rear derailleur
1) Mechanical failure. The gear shifter most often breaks down due to mechanical damage, for example, when a cyclist falls on the track. The first step is to make sure He’s not bent. Ideally, the foot should be parallel to the cassette stars. If there is even a slight skew, you can judge the deformation of the “cock” (rear derailleur bracket), and not the derailleur itself.
Often, after impact, the switch is bent inward, closer to the spokes. Sometimes it hits the needles. It’s bad if the frame is NOT equipped with a removable bracket. then the spokes, derailleur and dropouts break. all this leads to frame breakage. The bracket is attached to the frame with a bolt and the rear derailleur is attached to the second bracket. Straightens in a simple way. just pull the switch. But this only works with a slight deviation. Otherwise, you just have to replace the “rooster”;
2) Poor cable lubrication and contamination;
3) Incorrectly adjusted rear derailleur;
4) deterioration of related parts. Worn out sprockets and chains, rollers in poor condition also lead to breakage. On their own, poor quality rear derailleur models often break down. A lot of problems can be caused when shifting gears and a malfunction of the shifter.
If you experience difficulty in shifting gears and the bike is unruly on the move, inspect the bike carefully. When adjusting, do not pull on the rear derailleur foot only, as this may lead to deformation.
You will need: hex keys or a set of them (a 3 and 5 mm key is required), a Phillips screwdriver. Before starting debugging, it is important to make sure that the switch is still functional.
The gear selector is a delicate mechanism in hard-to-reach places. Therefore, before starting direct adjustment, it is necessary to eliminate key obstacles to the quality of the procedure.
Pay attention to the cleanliness of the bike, its SEPARATE mechanisms associated with the operation of the switch. Take care of your bike chain lubrication. Next, the bicycle chain is transferred to such a position that it becomes on the small stars in front and behind at the same time. To do this, find on the switch the adjusting screws with the inscriptions H and L. It is necessary to the maximum Unscrew the screw under the letter “L”.
Then Unscrew the cable tensioner clockwise until it stops. A similar one is located on the shifter. The procedure should be repeated with it. Remember that the rear derailleurs have five key details:
1) Bolt and nut for securing the cable;
2) Screw with hollowness and cable tension adjustment;
3) Screw for limiting the stroke, tossed over to the largest sprocket (L);
4) limit screw for small sprocket (H);
5) Tensioning screw for chain.
Some low-cost models do not have cable and chain tensioners. The final preparatory operation is to unscrew the screw that secures the cable directly to the switches. If rust forms, it must be replaced. Slight wear of the part indicates further operation with a prerequisite for cleaning and lubrication. Place the chain on the smallest chainring at the front and the largest chainring at the back, then pedal back. Then the upper roller of the rear derailleur, turning the tension screw, bring it as close to the star as possible, but so that it does not touch it. Such actions will help to achieve smooth gear shifting. At the end of the preparation check the ease of sliding of the cable through the “shirt” on the bike frame. Sometimes it needs to be rinsed.
Begin adjusting by checking the position of the top roller. it should be on the same vertical line or slightly to the left of the smallest cassette star above it, or slightly offset to the left when viewed from behind. The position can be corrected with the adjusting screw marked “H”. To move the roller to the left by turning the screw clockwise, to move it to the right. vice versa. Set up the high gear limiter like this:
1) put the largest star in the front and the smallest in the back;
2) Loosen the shift cable by loosening the derailleur bolt holding it. It is possible to screw in the cable tension adjustment on the switch and on the shifter to the maximum;
3) Make sure that both rollers are in the same plane with the smallest sprocket;
4) at the end of the adjustment, it is necessary to pull the cable and clamp it on the switch.
After installing the cable, you must go to the setting of small gears. Place the chain on the rear sprocket with the largest diameter. Next, check the position of the rollers under the large sprocket. The bolt responsible for the position of the rollers is located under the letter “L”. Adjust the chain if the derailleur has the ability to adjust the tension level. Each cyclist selects the optimal settings for himself. it is advisable to remember them in order to ensure comfortable use of the bike.
Modern models have two spring-loaded levers. The lower one lifts the switch frame upward, when positioned on small stars. The upper one provides movement of the frame back to the large star. The spring tension of both levers must be balanced for correct gear shifting.
I set the chain to the lowest gear, when the screw is loosened, the guide roller rises, Approaching the star, reducing the angle of inclination of the chain. this improves the shifting quality. The roller should not touch the sprocket and the gap should be approximately 5 mm. It is advisable to perform this procedure when replacing the cassette or when changing the chain length.
How to switch gears correctly
After adjusting the rear derailleur, you need to make sure that the gears are shifted correctly. Thoughtless “clicking” of the switch is not the best solution for testing the switch functionality. The key rule is that gear changes are carried out while the bike is moving. Before changing the speed, it is desirable to put less pressure on the pedals. Change gears sequentially. If you want to climb a mountain on the move, change the gear to a lighter one at the start of the immediate climb. To descend from a hill, the same rule is relevant, but you only need to switch to a gear in which it is more difficult to pedal.
Combinations of correct combinations While for different riding
Experienced cyclists select the optimal sprocket combinations for a comfortable ride with their bike model. The most popular combinations are:
for urban driving and asphalt roadway outside the city. a large front and between the 4th and 8th rear sprockets;
for cross-country travel or for fast driving on the track. a combination of a large chainring with a follower (3rd and 6th);
when going uphill. a combination of a small leading star with a driven one (from 1st to third).
Too much skewing of the chain will shorten its life. As soon as there is a sudden extraneous sound when driving, immediately stop and check the switch for faults.
Cable and shirt maintenance
Sometimes it is enough. Keep your shirts and cables clean and lubricate them regularly with liquid oil. It is then much easier to adjust the bike’s rear derailleur. Switches of different rulers and manufacturers serve different periods. it all depends on the price range. But even the durability of cheap switches can be extended with gentle handling and care.
A cable shirt is needed to keep out dirt. If you find a torn cable with unbraided threads, then hurry up to replace it with a new one.
In case of cable corrosion and constant jamming in the jacket, it is better to treat it with graphite grease. Then the rear derailleur adjustment will advance faster and the gear shifting will remain as smooth as before. Damaged shirts should be replaced.
Diagnosing a cock problem
If the chain throwing by the rear derailleur fails, there is a reason to check the “rooster” for serviceability. The rear derailleur is often damaged. There is a huge load on it. Often from a strong blow to the log and the curb, the “rooster” bends or bursts. Therefore, make sure that the two tensioner rollers are strictly vertical in relation to each other.
The dissonance of the geometrical parallels of the rollers means breakage. The chain, passing along the rollers, must be strictly vertical. without distortions. DO NOT level it in a field, forest, snowy mountains. Trying to straighten it by hand will only bend the switch frame. Experts do NOT recommend that you straighten the curved cock by pulling on the switch. Its frame is very fragile. First, it will bend, then the fasteners will deteriorate. this will only aggravate the situation with the repair. It is better to completely remove the cock, spread it out on a flat surface and use tools in an attempt to straighten.
Following our instructions, you can independently consolidate theoretical knowledge in a bicycle in practice. No one but you will actually be able to make it work: only you know all its pros and cons.
