Setting up the speed switch on a stels bike

Correct installation of the front derailleur

The correct position of the front derailleur is considered such that the longitudinal axis of its guide frame is parallel to the chainrings, and the distance from the bottom of its outer part to the largest chainring is no more than 2 mm. To make it easier to set the correct throwing position, it is advisable to remove the chain.

We set the distance from the bottom of the outer part of the frame to the largest star by moving the crossover along the vertical tube of the bicycle frame. We bend the parallelogram of the switch from the frame towards the largest sprocket, and, aligning the frame and the large sprocket relative to each other, we try to achieve the minimum distance (no more than 2 mm) at which its outer part does not touch the teeth. To simplify this procedure, you can insert some object between the frame and the parallelogram.

If you bought a new derailleur from Shimano, then this procedure is simplified by the fact that there is a plastic sticker on the transfer frame with marks that indicates at what level it should be installed relative to the large star of the system.

After we have determined the height at which the switch clamp will be fixed, make a mark with a marker and slightly tighten the clamp fixing bolt.

To adjust the position of the frame axis relative to the star system, loosen the clamp bolt (while the cable should be folded back) and, by rotating the switch, adjust it so that the frame is parallel to the front sprockets. Due to the complex geometry of the latter, it is quite difficult to determine by eye. You can navigate by the parallelogram (if the design allows it). To simplify this operation, you can stick a ruler (on double-sided tape) or other object to the switch frame (on the double-sided tape) or other object that will simplify the positioning of the switch.

After that, we slightly tighten the clamp bolt and re-check the distance from the lower edge of the frame to the largest sprocket in the system, and the parallelism of the longitudinal axis relative to the chainrings.

If everything is fine, then completely tighten the clamp bolt.

This completes the adjustment of the position of the front derailleur. Now you can put on the chain and start setting up.

Things to do before adjusting the front derailleur

Speed ​​selector setting

In order not to keep the bike suspended while tuning, try hanging it from the saddle, thereby raising the rear wheel. You can also use an ironing board for this. We put the bike with the upper tube of the frame on the ironing board plate, threading it into a triangle.

Setting up the front derailleur is straightforward. We will write it down point by point for greater clarity.

  • We set the lowest speed using the switch on the steering wheel (remember that at this stage the cable should not be attached to the crossover). We twist the adjustment of the tension of the gearshift cable on the shifter until it stops clockwise (if you look at the entrance of the shirt into the shifter) and return it back 1-2 turns. Many recommend tightening completely, but as practice shows, for further fine tuning, it is better to leave a margin for tension / loosening of the cable in both directions.
  • Set the lowest speed on the rear derailleur (largest sprocket). As a result, you will get the first speed front and rear (the chain should be on these stars).
  • We adjust the limit switch “L” so that the inner part of the frame is as close to the chain as possible, but does not touch it when pedaling. To do this, if you need to move the frame towards the bike frame, you should turn the bolt L counterclockwise, from the frame. clockwise.
  • We insert the cable into the place of fixation on the gear selector and, pulling it (with your hands, do not use pliers), tighten the cable bolt.
  • We switch gears from the front to the largest star, from the back to the smallest (the chain should be on these stars).
  • We adjust the limiter “H”. It is necessary to achieve such a position of the guide frame in which its outer part is as close to the chain as possible, but does not rub against it when pedaling. To move the frame towards the frame, turn the screw clockwise, in the opposite direction. counterclockwise.
  • We set the 5th speed on the rear cross-over. After that, turning the pedals, we change the speeds with the front derailleur over the entire range (3. 2. 1. 2. 3) several times. Then set speed 2 to the front and, shifting reverse gears, check that there is no friction between the chain and the frame in positions 2. 2 and 2. 7 (example for 24 speed bicycles). expensive front derailleurs can achieve frictionlessness even at 2-1 and 2-8 (although you should be aware that these are not normal modes and should not be used when driving). If there is friction of the chain against the frame in these positions or an indistinct gear shifting, then the cable tension should be adjusted by rotating the adjustment on the front shift lever. In case of problems when switching from a smaller chainring to a larger one, tighten the cable (turn the adjustment counterclockwise), and when it is impossible to switch from a larger to a smaller one, loosen it (turn the adjustment clockwise). If there are no Комментарии и мнения владельцев on the work, then the next test must be performed under load when driving on roads.
  • We find a flat section of the road (without bumps and slopes) and check the operation of the front crossover while driving. In case of any problems when switching, right on the go, we rotate the adjustment on the shifter in the direction we need.

If you do not understand something about how to set up the front derailleur, then we advise you to watch a video on this topic.

How to set up and adjust the bike’s front derailleur

Sooner or later, every cyclist has to adjust and tune the bike’s front derailleur. And the cheaper the transfer, the more often. This happens for many reasons. For example, the cable is stretching, or you decide to adjust after replacing the derailleur. This does not change the essence. For this operation, you need to perform approximately the same steps. Therefore, we decided to talk in detail about how to set up and adjust the front derailleur of the bicycle using the example of pictures and videos, and what needs to be done before performing this procedure.

Design and principle of operation of the front crossover

The design of the front derailleur is very simple. We will consider all its components, as well as their purpose below.

  • Clamp. This part attaches the front derailleur to the bike frame.
  • Parallelogram. Parallelogram-shaped hinged spring-loaded part. It is the main moving part of the front bulkhead, to which the frame is attached.
  • A guide frame that has an outer and an inner part. A chain runs inside her.
  • Adjusting bolts L and H (stops). There are two of them. They restrict the movement of the guide frame towards the frame (L) and away from it (H).
  • Cable fixing bolt. Locks the gear shift cable.

The principle of operation is based on a simple collision of the chain on the desired star. When the gear is shifted from a larger (in diameter) star to a smaller one, the cable tension is weakened, and the switch spring pulls the parallelogram with the guide frame a certain distance towards the frame. The outside of the frame pushes against the chain, causing it to bounce onto the smaller sprocket. When switching from a smaller star to a larger one, the opposite process occurs. The derailleur cable tightens and moves the parallelogram and guide frame away from the frame. The inner part of the frame presses on the chain, and thanks to the special shape of the frame itself, as well as special hooks on the sprockets of the front system, the chain engages and throws it onto a large sprocket.

This design provides limiting bolts (L and H), against which the parallelogram rests when reaching the end positions. If the setting of the front derailleur stops is not correct, the chain will jump off the carriage or connecting rod.

Adjusting and adjusting the front derailleur of the bike

After you have made all the preparatory measures, you can proceed to the adjustment and tuning. If you install a new derailleur or remove it during cleaning, then before adjusting it should be positioned relative to the chainrings, and then proceed with the adjustment.

Why can’t I adjust the front derailleur

If you have not been able to clearly adjust the front derailleur of your bike several times, then most likely you have one of the following problems:.

  • Wrong switch or star system.
  • The switch is deformed or out of order.
  • Tight running of the cable in the shirt.
  • The shifter is out of order.
  • The chain is too stretched.
  • Derailleur, cable and chain are heavily soiled.

Adjusting the front derailleur

  • 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.

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.

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 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.

Correct cycling gearshift setting

Modern bicycles equipped with a gear system allow you to move quickly and with minimal energy losses in any conditions: long climbs, rough terrain, roads with sharp turns that require constant changes in speed and gear ratio. This can also include driving against the wind, off-road conditions, poor quality asphalt In general, the value of the transmission unit is simply colossal, especially on mountain bikes.

Despite the invaluable help, the transmission is great and requires frequent attention, care, and sometimes long and tedious fuss. One component that needs to be taken up periodically is the shifting mechanism, which consists of front and rear derailleurs. At first glance, the arrangement of these parts seems complicated. In practice, setting up gear shifting is very simple.

Why is there a violation of gear shifting

To understand what action should be taken to adjust gear shifting, you need to understand what causes may lead to the problem in question. Experts identify several such predisposing factors:

  • deformation of the rooster;
  • stretching the cable;
  • deformation of the speed switch;
  • malfunctioning return spring.

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.!

Correct adjustment depending on the type

Adjustment is necessary in cases where shifting speeds on the bike starts to cause problems. As a rule, such actions are carried out in such cases:

  • a bike was purchased that was poorly adjusted in the sports department;
  • violation of the rules for transporting a bicycle;
  • vehicle mileage is large enough.

The work will need the following tools:

The front derailleur setting is significantly different from the rear derailleur setting.

Necessary terminology

To understand the process of self-adjusting the speed switch, you need to know the definition of some specific terms, otherwise it will be difficult to understand the instructions.

  • Speed ​​switch (crossover). This is a transmission element that is specifically responsible for gear shifting. If there is a rear crossover, then it also acts as a support for the tension of the bicycle chain. The crossover (back and front) can be described as follows: it is a parallelogram mechanism equipped with a powerful return spring, on which the frame is fixed. The rear derailleur has two rollers inside the frame. if the level of cable tension increases, then the frame shifts the chain to large stars, and if this cable tension decreases, then the chain is shifted towards small stars with the help of the frame. The mechanism of the front derailleur works in the same way.
  • Shifter. It is designed to switch speeds by changing the tension level of the cable. Most often, the shifter is located on the handlebars, but in some models of bicycles it can also be located on the lower tube of the frame triangle. Note:shifters and speed switches have a common connection on the steering wheel (this is provided by a cable) and are covered with a jacket.
  • Cassette. This is the name of the rear transmission unit, which consists of stars of different sizes (of different diameters and with a different number of teeth) and is installed on the rear hub drum. If the bike is old, then a ratchet is used instead of a drum in the rear hub.
  • Cock. It is a metal part that helps maintain the integrity of the frame and rear derailleur in the event that the vehicle has been hit. The rooster is always attached to the frame, and a cross-over is already attached to this metal part. When a blow occurs, it is this very cock that breaks, and the frame and the speed switch (crossover) remain intact.
  • System. This is the name of the front transmission unit, which consists of stars of different diameters and with a different number of teeth. These stars are fastened to each other and the connecting rods with special hollow bolts on the connecting rods, but you need to know that there are no hollow bolts in cheap bicycles. the stars and connecting rods are riveted to each other.

Take the survey

The following types of mechanisms are professional:

  • Shimano XTR, Deore XT. The device has a high degree of reliability, but belongs to the category of expensive.
  • Saint. A professional, reliable variety that differs from the previous ones in the raw materials used. Composite materials are used in its manufacture. Thus, it is possible to reduce the weight of the components.
  • Hone, Deore LX. Top class products, but more affordable than other professional movements.

Among sports equipment, the Deore bike’s derailleur system deserves attention. This model belongs to the initial group. Parts with reduced weight and maximum strength are used in the manufacture.

The Alivio model is also considered to be sports. It is a cross between amateur and professional devices. Often, preference is given to it, due to the small mass of parts.

XTR Deore XT Saint Hone Deore LX

Amateur gears can be used to change gears:

  • Acera. Able to withstand heavy loads. Often, beginners use the mechanism incorrectly, so manufacturers have made it unpretentious. When adjusting the gear shifting on a Shimano bike, this does not require high precision.
  • Altus. An affordable device for beginner cyclists. Designed for quiet walks in parks and city streets without heavy loads and frequent speed changes.
  • Shimano Tourney. The mechanism is not designed for extreme driving. Shimano Tourney often has unexpected situations.

Shimano derailleur settings, regardless of variety, follow the same setup. All mechanisms function the same, are considered interchangeable.

How the switches work

Using the handle and shifter, the cyclist activates the required speed. In a certain position of the handle, the cable is pulled. As a result of this tension, the frame is thrown onto larger sprockets; when the cable is loosened, it is not thrown onto small sprockets. As mentioned above, you can start setting up your bike from the rear derailleur. Procedure for adjusting the rear derailleur:

  • select the second star in the front block, and the smallest in the rear one and set the switch chain on them;
  • The bike’s rear derailleur system has two bolts that act as stops. One is abbreviated as H, and on the other. L. These two bolts are used to adjust the high and low gears on the sprockets. If during the adjustment process any extraneous sounds arise, you can get rid of them with the help of the latch;
  • check the tension of the cable and if the tension does not correspond to the required one, use the regulator located on the shifter;
  • Test the switching quality. If the switching occurs smoothly, no extraneous sounds are heard, then you did everything right.

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.
