How to properly adjust bike speeds

Preparing to set up the transmission

It is wrong to start adjusting the gearshift system right away. The bike has been on the road for some time, therefore, there is a certain amount of adhering dust on the chain. Be sure to remove all the dirt from it, lubricate the rollers, sprocket points and the switches themselves. Sometimes problems with a tight transition from one speed to another lie in the dirty chain. If, after cleaning and lightly lubricating, the problem is resolved, then you do not need to adjust the switches.

Next, pay attention to the drive cables: they must be flat, without bends. Otherwise, they will have to be changed. Inaccurate shifting and jumps may be due to faulty cable.

Another preparatory procedure is to inspect the cock near the rear derailleur. The rooster must be in an upright position and strictly in the same plane with the rollers. You can align it, but it is better to change it to a new one.

As for the bike’s front cassette derailleur, you need to make sure that the inner frame is parallel to the chain travel. The distance between the largest sprocket and the outer frame of the switching device must be within 2-3 mm.

Everything is all right, and the speeds keep turning on badly? Then it’s time to adjust the transmission. We loosen the tension of the cable to the maximum, tighten the drums on the switch until they stop. After adjustment, the system will work more accurately, and there will also be a necessary margin in case of lengthening the drive cable.

What to do if you can’t adjust the bike‘s rear derailleur

There are several methods for solving this issue. But if the standard tuning instruction did not work, to tune the rear derailleur you need to:

  • dismantle the chain, remove the cable;
  • move the switch to the chain position to the smallest star;
  • use adjusting bolts (this way you can tighten the cable);
  • set the adjusting bolt H to the extreme position;
  • move the part called the parallelogram to the big star and adjust the position of the bolt L.

The regulator is fixed with bolts. It must be set to the extreme position. After that, the chain must be displaced in this order: the front cassette is the largest star in diameter, the rear one, on the contrary, is the smallest.

Despite the fact that the bicycle was invented a long time ago and, it would seem, should have been out of date for a long time, but this two-wheeled vehicle is gaining more and more popularity every year. Cycling enthusiasts prefer this type of transport due to its convenience, ease of operation, environmental safety and practicality. Not only ordinary bicycles are very popular, but also mountain, track bikes, which use modern innovative technologies. In order for the owners to enjoy cycling, they need to take care of it and monitor the condition of all parts and assemblies. If, in the process of cycling, you hear extraneous sounds, creaking, knocking and twitching during gear shifting, it’s time to pay attention to such a detail as the gear selector.

Adjusting the front derailleur

properly, adjust, bike, speeds

  • We put the speed switch in the following ratio: the smallest star in the front and the largest in the back;
  • We unscrew the cable;
  • Using the screw of the limiter for low gears, we adjust the position of the frame, it should be at a distance of no more than 3 mm from the chain;
  • Stretch the front derailleur cable slightly;
  • Switch the speed to the middle sprocket and check if the chain is touching the outer frame. If it touches, it is necessary to tighten the cable more;
  • We put the derailleur on the smallest sprocket and check how easy it is to change gears. If the switch does not work, adjust the high gear limiter screw.

How to adjust the front derailleur

There are also clear and simple step-by-step instructions for adjusting the front derailleur:

  • Shifting the chain to a smaller star.
  • Unscrew the fixing screw and release the cable.
  • We find the screw marked “L”, with its help we adjust the position of the frame so that the chain is between the plates of the frame, but at the same time does not touch them.
  • We stretch the cable, fix it with a screw.
  • Now we move the chain in the cassette to a smaller sprocket. it is convenient to do this using the rear derailleur.
  • With the front derailleur, move the chain to the middle sprocket and look. if the chain on the second one touches the outer side of the frame everywhere, then you need to increase the cable tension using the drum located on the left shifter.
  • We switch the gear to the largest sprocket in the cassette and check. if the chain touches the walls of the frame, you need to move the last element so that the chain is in the middle. This manipulation can be done using the screw marked “H”.

How to properly adjust the rear derailleur

To independently adjust the rear derailleur on a bicycle, you just need to strictly follow the step-by-step instructions from specialists in this process. So, follow all the steps:

How to Properly Adjust Bicycle Shifting

  • Move the chain to the small sprocket with the right shifter.
  • Unscrew the fixing screw and release the cable.
  • Find the screw marked “H”. Use a screwdriver to adjust this screw so that the smallest star lies in the same plane with the rollers, which are located in the foot (frame).
  • Pull the cable by hand and fix it with the screw.
  • Check the operation of the switch, and if it does not work correctly, the chain does not switch well to large stars, then you need to tighten the cable harder (either with the help of a drum or with a switch).
  • Move the chain to the largest sprocket available in the cassette.
  • Find the screw marked “L” and adjust it so that the tab (frame) and the sprocket are in the same plane. in this case, the crossover will not be able to get into the spokes of the front wheel.

Setting up the rear derailleur

  • Setting the switch to the smallest star.
  • Loosen the cable. To do this, unscrew the clamp screw located on the rear derailleur.
  • Putting the front derailleur chain on the middle sprocket.
  • We check the operation of the chain. To do this, you just need to twist the pedals. If the chain starts to fall, adjust the high gear stop screw. As a result, your rear derailleur and the smallest sprocket in front should be on the same line.
  • Pull the cable tightly and tighten the bolt, which is responsible for fixing the tightening.
  • We begin to test the switch by clicking each speed from the lowest to the highest. If in a certain place the system fails, then adjust the tension of the cable until all speeds are easy to switch.

When adjusting the speed switch, be sure to remember that all manipulations with the cable must be done smoothly and very carefully. Be patient and avoid sudden movements. When loosening or tightening the bolts, do it gradually, no more than one turn at a time.

Remember that speed tuning is a very important issue that affects the overall performance of your bike. Therefore, take the drive mechanism very seriously, and once you have mastered the technique of setting speeds, carry it out systematically.!

The bike chain is one of the most important parts of your bike, so not only the overall feeling of riding, but also your safety depends on its serviceability.

The drivetrain plays a very important role in the operation of the entire bike, so you must carefully monitor the wear of its individual parts.

In order to install disc brakes on a bicycle, you can go to any bike workshop, or carry out this process yourself.

The braking system of any bike is the most important element of the mechanics, which is responsible for your safety during the trip.

The need to remove the bike chain occurs when it needs to be replaced, cleaned or a broken link must be removed.

How to fix defects

The speed switch will work perfectly and the bike itself will be with a new (or not very old) cable, with absolutely intact shirts (and not dry!) ​​And not deformed (or in a small volume) stars and chain.

If the cable is just stretched, then you just need to pull it up. But if the cable breaks, then you cannot do without replacing this element. The process of replacing the cable is not difficult, the main thing is to strictly adhere to the recommendations of the specialists:

  • unscrew the cable fixing screw, which is located on the cross-over;
  • pull the cable out of the shirts;
  • if necessary, disassemble the shifter and pull the cable out of it;
  • a new cable must be inserted into a special groove in the shifter, and it is the metal tip of the cable that must enter into the groove;
  • lubricate the entire cable with a special grease, you do not need to spare the consumable;
  • pass the cable through the shirts;
  • there are special grooves on the frame, into which shirts are tucked;
  • fasten the cable with a screw on the front end.

In case of poor gear shifting, pay attention to the return spring. it must be clean and lubricated. To achieve this, you just need to rinse the spring under running water, dry it completely and lubricate it thoroughly.

If the frame of the rear derailleur is crooked, then this can only mean one thing. the cock is bent. If this is not critical, then you can correct the cock with your hands. you need to take the rear switch in your hand, which is fixed on the cock, and hold the frame with the other hand. Slowly pull out the problematic transmission element (cock) until relatively even setting.

Note: this “repair” of the cock is a temporary solution to the problem of shifting gears. The fact is that the rooster is a consumable that needs to be changed in time, and not constantly repaired / pulled.

In some cases, the bike owner pays attention to a deformed rear derailleur (the front derailleur rarely suffers on impact). it can also be returned to its original position with the help of hands. But if the rear derailleur is deformed too much, then it is advisable to replace it.

Note: After performing specific manipulations to repair bent / deformed parts, you should not use the bike for too long. this may end in a fall, another breakdown at the most inopportune moments. And in some cases, such carelessness can lead to a traffic accident.!

How to adjust the speed switch on a bike

Having become the happy owner of a bike, you should be prepared for the fact that over time you will have to carry out basic maintenance of the bike yourself. Of course, if we are talking about a serious malfunction, it is best to seek help from specialists, but many manipulations can be safely performed on your own.

How to properly adjust the rear and front derailleurs on a bicycle: photo and description of the process

Despite the fact that the bicycle was invented a long time ago and, it would seem, should have been out of date for a long time, but this two-wheeled vehicle is gaining more and more popularity every year. Cycling enthusiasts prefer this type of transport due to its convenience, ease of operation, environmental safety and practicality. Not only ordinary bicycles are very popular, but also mountain, track bikes, which use modern innovative technologies. In order for the owners to enjoy cycling, they need to take care of it and monitor the condition of all parts and assemblies. If, in the process of cycling, you hear extraneous sounds, creaking, knocking and twitching during gear shifting, it’s time to pay attention to such a detail as the gear selector.

Setting switches at home

Now let’s figure out how to set up the high-speed system ourselves. Derailleurs on bicycles with multi-gear transmission are divided into front and rear. The latter are most vulnerable when riding in a variety of road conditions, the risk of damage is higher compared to the front ones, but the adjustment must be done at the very beginning. Obviously, the rear derailleur serves more stars, so it takes longer to set up.

Attention! If there is damage, and the tensioner is not parallel to the frame and cassette, then it will not be possible to correctly adjust the system!

First you need screws L and H. they are clearly visible, no need to look. Also includes a cable adjuster, tension and fixing screws.

How to Adjust a Rear Derailleur – Limit Screws & Indexing

  • H is used to align the roller with the small rear sprocket. By tightening the screw L, we set the roller on one straight line with the large rear sprocket.
  • Set the highest speed on the shifter.
  • Tension and fix the cable with the fixing bolt.
  • Large gears should be included without interference, otherwise, using the adjuster, the cable is slightly weakened. Additional tension will be needed if gears are poorly reset.

Actually, the adjustment itself is made, it remains to adjust the switching accuracy. This is especially true for systems with a large number of stars. For this, the chain is mounted on a large chainring at the back and a small chainring at the front. By tightening the tension screw, we achieve the optimal position of the roller. as close as possible to the cassette. The same must be done and vice versa: set the chain to the maximum chainring in front and minimum. at the back. The roller should not rub against the cassette, just be located next to it.

How to properly set up the switch in front:

  • Check device attachment.
  • At minimum speed, release the cable tension.
  • Use screw L to create a gap between the derailleur body and the chain (1 mm).
  • Secure the cable with the adjusting bolt.

The same should be done with the H-screw. The maximum speed must be set, and the gap with the chain must not exceed one millimeter.

Adjust the speeds on both derailleurs until the chain is free to swing from one chainring to the other. If it is difficult to walk, it is necessary to adjust the correct position of the cable using the adjusting bolt.

After all the manipulations, the entire system is checked. To do this, you need to ride a bike and try all the recommended gear ratios. Note that on mountain bikes, the transmission adjustment is a common periodic procedure, and if suddenly the transmission goes tight, we are not in a hurry to draw conclusions about the breakdown, but we do what is described above.

Do not think that a high-quality transmission does not need to adjust the shifting system. Yes, it may be necessary to do this less often for shimano components, but sooner or later you will still have to face.

We just saw an easy way to adjust the front and rear derailleurs. Is it really necessary? Adjustment of the shift mechanism is necessary for the transmission, like tires for a wheel. Timely assistance to the “traffic node” will allow not only to solve current problems, but also to prevent them in the future. Eliminate all inconveniences in time and ride with pleasure!

How to adjust the rear derailleur on a bike?

The rear derailleur is set as follows:

  • We set the speed on the bike in such a way that the chain is on the smallest star.
  • Loosen the shift cable by unscrewing the clamp screw located on the rear derailleur.
  • Using the front derailleur, install the chain on the middle sprocket of the front carriage.
  • We start to pedal. If the chain starts to fall off during movement, the screw of the upper gear limiter should be tightened, which is indicated by the letter H. Ultimately, the smallest star on the front carriage and the crossover should become one line.
  • Tighten the cable and fix it with the bolt.
  • We check the operation of the switch, changing the speed from the lowest to the highest. If somewhere the switching is carried out incorrectly, you need to adjust the tension of the cable by turning a special drum on the shifter.

Be sure to remember that any actions with the cables are best done slowly and very carefully. When tightening or unscrewing the bolts, do not make more than one turn at a time.

Setting up the rear derailleur

The first step is to put the chain on the smallest sprocket in the cassette. This can be done using the right shifter. it is this detail that directly affects the rear derailleur on a bicycle. To release the cable, you need to unscrew the screw that fixes its position. The screw marked H must be unscrewed with a screwdriver so that the smallest sprocket is in the same plane with the sprockets in the foot. Next, the cable must be pulled and secured with a screw.

After that, you should definitely check the work of the transfer. If the chain does not switch to large rollers (stars), then the cable must be tightened even more, using the drum already on the shifter or on the transfer. The chain is moved to the largest roller and the position of the switch is adjusted with the screw L. Ideally, the cross-over should not be able to hit the knitting needles, that is, the foot and the star should be in the same plane.

Let’s define the terminology

Before talking about such a concept as adjusting the speed of a bicycle, you need to understand the basic definitions so that even a novice cyclist understands what is at stake.

The speed selector is sometimes called a toggle switch. It is an indispensable component of any modern speed bike. It looks like a rectangular spring mechanism with a frame (or foot) attached to it. When it comes to the shifter, it is impossible to ignore the shifter. a device that is designed to control the transfer by adjusting the cable tension. Usually this important part is attached directly to the handlebars. But there are bicycle models where the shifter is located on the down tube of the front triangle of the frame.

Every seasoned cyclist knows what a rooster, cassette and speed bike system is. For the rest, we will give definitions to these terms:

How to adjust the speeds on a bike without fixing screws? The two notorious switches marked H and L are right on the cross-over. First. Hight. this is a stop screw for adjusting large gears (or small sprockets or gears). L (Low) adjusts small gears. Their location may vary on different models.

Possible causes of indistinct / incorrect speed switching

Before talking about how to adjust the speeds on a bike, let’s talk about the possible causes of such defects:

Finding out how to set the bike speeds? Learn how to adjust the speed of your bike?

Despite the fact that the derailleur has a primitive mechanical design, adjusting it can be quite difficult for cycling enthusiasts. Read this article to learn how to set your bike speeds and learn how to use the derailleur correctly.

How to adjust bike speeds?

There are two gear selectors on modern models of these vehicles. front and back. Usually, the adjustment begins with the latter, but there are also cases when it is necessary to adjust only one crossover.

How to fix defects?

Every speed bike must have an attentive owner. That is all the details. cable, sprockets and switches. must be lubricated with special agents. lubricants.

If the cable is stretched, it can be slightly tightened. In the event that it has already been torn, it should be immediately replaced with a new one. Algorithm of actions:

If the spring does not work well enough, then it must be rinsed with water and lubricated.

Rooster deformation can be seen not only in special bike shops. A bent cock is visible if you place the rear derailleur frame obliquely. In case of slight deformation, it can be leveled independently by pulling it out until the hind foot is level. However, remember that this is only a temporary measure. It is best to replace a deformed part with a new one. The same goes for the bent crossover.

Adjusting the front derailleur

This algorithm of actions will tell you how to adjust the speed on the bike by setting the front overhaul:

After reading this article, you will know for sure the answer to the question of how to set the speeds on your bike. The main thing. follow the above algorithms, and the process of adjusting the speed switch will not seem so difficult to you.
