Adjust the speed switch on the stern bike

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 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Despite the fact that the bicycle was invented a long time ago and, it would seem, should have been out of date for a long time, but this two-wheeled vehicle is gaining more and more popularity every year.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.

Leave the chain on the middle sprocket of the front block and place it on the large sprocket in the rear block. If chain friction is observed, re-engage adjuster L. To adjust stop H, the chain moves to the largest sprocket at the front and smallest at the back. The adjuster will help to position the chain in the optimal position without friction and excessive tension on the chain. At the end of the work, be sure to check the quality of its implementation.

How to adjust the speed switch on a bike

It often happens that either the speeds on the bike are not switched clearly, or some new transmission elements have been installed. In this case, you will need to adjust the speed switch and it is quite possible to do this work on your own, without contacting specialized workshops.

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 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.

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.

Rear derailleur

The gear selector is an important part of a multi-speed bike. Thanks to this component, it becomes possible to move in extreme conditions, which include upwind movement, ascents, poor road quality. The transmission unit must cope with all these problems. The quality of the ride and the safety of the cyclist depend on the smooth operation of the speed switch. This skill is very useful, and every bike owner should learn how to independently adjust the gear shifter. Each cyclist can make adjustments to the bike’s gear shifters on their own. You need to study the theory in detail by reading the instructions, or using the advice of experienced bike owners.

Before setting the derailleur, the rear derailleur must be adjusted. Placing the bike in the correct position (wheels up) will greatly facilitate the entire adjustment process. So, all the necessary details will be in plain sight, and it will be much easier to get to them.

Reasons for poor gear shifting:

  • physical defects of the switch parts;
  • contamination of parts. To prevent this from happening, the components of the transmission unit must be periodically cleaned of dirt, dust and old grease;
  • worn out cable with elements of damage. Such a part requires replacement;
  • damage to the cock.

If you observe damage, deformation and wear of the constituent parts, they must be replaced as they are practically irreparable.

If all parts are OK, adjust the switch. What is the speed selector made of? The components of the speed switch are as follows:

  • The handle for shifting the speeds, located on the steering wheel;
  • A shifter that attaches to the handlebars near the handles. Handles and a cable are attached to the shifter. It is with the participation of the cable that the impulse is transmitted from the shifter to the stars;
  • Cassette, which includes stars of different sizes;
  • front fixing mount;
  • rear derailleur, whose main function is to transfer the chain to the necessary sprockets.

Correct installation of the front derailleur

You can only start the front derailleur setting after adjusting the rear derailleur. Installation is the initial step in adjusting the speed switch. It’s very important to do it right.

  • before installing the switch, it is necessary to inspect the condition of the constituent parts and, if necessary, clean them from dirt and lubricate.
  • The next step is to adjust the location of the front derailleur. On the frame, it should be located along the pipe under the saddle.
  • Set the steering angle parallel to the drive sprocket on the front cassette of the transmission unit.
  • Next, you need to adjust the gap between the underside of the derailleur frame and the upper mowing line of the teeth of the large gear. The gap should be minimal.
  • Adjust the cable tension.
  • Place the chain close to the inside of the frame.

It is also worth paying attention to setting up the chain. The bicycle chain is a very important element, with the help of which the impulse is transmitted from one chain to another and the adjustment process takes place. The technical condition of the circuit is of great importance for the operation of the entire system. If, for some reason, the bicycle chain stretches or deforms, this cannot but adversely affect the operation of the entire transmission unit. To prevent this from happening, the chain must be periodically removed and cleaned, and then set the correct position. There are lock and lockless models of bicycle chains. They differ in the way they are connected. To remove the locking chain, it is enough to find the link with the lock and disconnect it with a screwdriver. The lockless bicycle chain is disconnected using a squeeze. This tool helps to push the link axle out and make the connector. If it skews for some reason, this can adversely affect the gearshift process.

One of the best manufacturers of bicycle parts, including derailleurs, is the Japanese company Shimano, which has a proven track record of producing products in which Japanese quality is combined with budget and price. Shimano derailleurs are suitable for all types of bicycles. Shimano derailleurs are installed on both regular touring bicycles and mountain and track bikes with gearboxes up to 33 speeds.

Another recognized market leader is Sram. The products of this company are used on bicycles of the city bike category, as well as on sports bicycles. Sram products are of good quality and affordable price for cycling enthusiasts.

Every bicycle owner who prefers this type of transport to others is obliged to understand how to switch its speeds. It is believed that the more speeds a bike has, the better it is. But in fact, speed only allows you to improve the quality of maneuvering and squeeze the maximum out of the bike’s capabilities, so then everything depends on the dynamic efforts of the person riding the bike. Conventional bicycles have a simpler design compared to high-speed ones. With a bike like this, there is less hassle, but it also has fewer options. In the transmission unit of such bicycles there are only two stars: one large and one small. Multi-speed bikes, which have gained popularity in recent years, have two sets of sprockets in their transmission units: front and rear. Each cassette consists of stars of different sizes. To switch gears correctly, you need to remember a few basic rules:

  • If your bike is not equipped with a planetary hub, you only need to switch gears on it while driving, otherwise there is a danger of damage to the bike.
  • During gear shifting, it is not necessary to apply significant dynamic forces, in order to eliminate the danger of a burst of flowers, it is advisable to change gears sequentially, without making sharp jerks.

Angle adjustment

The second problem is both installation and configuration. The entire device must be parallel to the stars of the common frame axis. This is determined by special devices or by checking the parallelism by eye: we simply bring the bike up to the mowing line so that one of the edges of the wheel, bushing or other landmark is on one mowing line and becomes “invisible”, and we check if our chain or frame does not diverge.

In case of serious deviations, we work with the installation of the switch, you may even have to remove the device, with small ones. with special adjustment screws, if there are any on our model.

Eyeliner

  • Checking the cable (it must be properly closed with a jacket, easy to pull and respond to the operation of the shifters).
  • Checking the shirts (on the surface of both the cable and shirts there should be no serious damage or obvious bends, as they will eventually lead to blocking of switching in one way or another).
  • Connection (the cable must be wound and clamped in the receiver without protruding burrs and sagging places).

The second step is to install and secure the switches. This is necessary if the switch is adjusted after it has had to be repaired or replaced. The third step is threading the chain. Before fastening the switches (the circuit must be threaded into them) or, conversely, after fastening (the circuit is closed already on the installed devices).

We check all the liners and fasteners, after which we proceed to set up.

Height adjustment

The very first thing to check on the front frame is its height. During installation, inaccuracies often occur when the switch is too far from the stars, or when it touches them. The mechanisms are imperfect and the purpose of the height adjustment is to properly adjust the frame (about 2-3 millimeters above the large star). After installation. check the distance by turning the system with the attached chain.

On planetary bushings

Gear shifting in planetary hubs is completely different from the usual described mechanism, but also requires periodic adjustment. A “pusher” is responsible for changing gears on planetary gears. a small element resembling a chain that connects the shifting mechanism inside the hub with a cable.

In order to adjust everything well, it is necessary to find the slot on the pusher (the connection point of the rigid and movable part of the device) and at the penultimate speed align it with the wheel axis (for this, special viewing windows are usually provided). The setup steps are as follows:

  • We set the penultimate speed: 2 for a three-speed hub, 3 for a four-speed.
  • We remove the boot or other protection of the connection point of the cable to the pusher.
  • We release the pusher and find the required point, tracking through the viewing window the coincidence of the spline and the wheel axis.
  • We tighten the cable with the screw, aligning the pusher.
  • Close protection.

It is difficult to make any other shift setting for the planetary hub on your own. You will need to completely disassemble all the mechanisms, which is quite problematic at home.

How to properly adjust the derailleur on a bike?

Before proceeding to setting the speed switch, you should understand its place in the entire drive mechanism and general settings, because, in addition to setting, the switch must be correctly set, the correct switching system must be suitable for it, and the chain must fit the stars. Problems with the switching system are not always caused by an incorrect setting, but with a poor installation or an erroneous selection of a combination of elements. In addition, by mistake, elements that do not match each other may be placed on the bike.

Limiters

Actually, this is what is usually called “switch adjustment”. this is working with High and Low limiters. The point is to keep the chain from falling off the sprockets in extreme positions. This setting is made simultaneously on the front and rear sprockets with the (ideally) disconnected cable. Those. first, the adjustment is made, and only then a cable is wound under the screw and pressed. This increases accuracy and eliminates tensioning effects that can interfere with work.

What do you need to know? Each switch has two adjustment screws, usually marked with two letters:

  • H. high or hard. “high”, the position of the chain on the largest star in front and the smallest in the back;
  • L. low or light. “low”, position on the smallest chain in front and the largest. in the back.

The purpose of the adjustment is to set the chain on the corresponding stars, rotate the corresponding bolts with a screwdriver until the chain is parallel to the frames and, accordingly, with the correct installation of the mechanism itself, parallel to the plane of the wheel and the stars. Additional conditions:

  • The chain should not fly off when switching to the extreme sprocket.
  • The frame or chain must not touch the axle and frame.
  • The chain should not “scratch” against the speed selector.

After adjustment, the entire mechanism should be assembled and checked for correct operation. All transitions must be clear so that the chain does not sag or touch the frame or frames. The shortcomings revealed in this “test drive” require a serious approach, because they can speak not only of incorrect tuning, but also of other problems in the bike, and it is better to fix it right away, and not expect serious damage.

Stretched rope

This defect is regulated by a drum on a shifter.

  • When the chain moves silently and bounces on large stars with difficulty, it means that the cable is stretched out. Rotate the drum clockwise until the part is tensioned to the desired position.
  • In the case when the chain does not want to descend on small stars, relax the cable by turning the drum counterclockwise.
  • Check the operation of the speed switch. If necessary, spin the drum more. Adjust until the chain bounces smoothly.

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:

  • 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.
