A trick for better switch performance
There is one secret to how to properly shift the gears on your 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. Over time, as you become more experienced, you will feel when to release the lever.
Bicycle front derailleur
Let’s start setting up the front derailleur. To do this, in the front we put on a small star, on the back. on a large one. Take the hex key to loosen the screw holding the cable. Take the screwdriver and the 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.
How do I switch gears on my 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 switch 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 is no problem. 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 take you by surprise. Competent gear shifting 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 switching forward speeds on the device. The right trigger coin is responsible for shifting the reverse gears.
How to change speeds
It is imperative to 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 no distortions simply 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 on the front is large and the chainring is also large. That is, you need to evenly switch both on the cassette and on the crank chainrings. Extremes are undesirable here, unless they are from the bottom side.

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 front to be thrown over to the second. If the chain hits the frame, then the cable must be tightened. We pull it with the “lamb”, it is located on the shifter, which is on the left. You need to turn until 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 tuned.
How to set your bike speeds so all your equipment works great
We adjust the rear derailleur. The chain needs to be translated into a small asterisk. After letting go of the cable, for this you need to unscrew the bolt that clamps it. After we find the screw that is responsible for displacing the foot of the rear derailleur. It is marked with the letter “H”. Using 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, it was lying in the same plane.
After that, we take the cable and pull it out as much as possible, then fix it with the screw, which we had released before. After fixing, we try how the rear derailleur works on the bike. If the chain is poorly thrown onto larger stars, you need to tighten the cable. This is done using a special “wing”, which is located where this cable enters the switch, it looks like a nut with more convex edges. We twist it clockwise.
We put the chain on a large sprocket. This is done with the screw, which is marked with the letter “L”, change the position of the switch in order to shift the foot and place it in line with the large star located on the cassette.
What not to do on the climbs
The only thing you should definitely not do when going uphill is to increase the speed on the front chainrings, switch from the first to the second and from the second to the third. You can increase the speed from behind absolutely calmly, without fear that something will happen to the bike.
If, after changing the gears, you hear a clatter or other extraneous sounds, then this means that the switching has not happened, 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.
What to do if your bike’s derailleur is broken
Transmission components must be kept in good condition at all times, lubricating the chain promptly, adjusting switches and troubleshooting.
As the kilometers increase on the bike, individual parts wear out, and if maintenance is not performed on time, the part may become unusable altogether. In this article, we will look at the most common problem associated with speed derailleurs.
It must be understood that the speed changes only when the chain moves forward. If you jerked the shifter, then you need to turn the pedal so that the chain spreads from one star to another. If, when switching, clicking or any other extraneous sounds are emitted, you need to adjust the switching.
The main reasons for inaccurate switching:
- The transfer cable is torn, stretched, or is on the verge of breaking.
- The switch itself is broken or the spring in it is worn out.
- The teeth of the rollers are worn down.
- The switch needs to be adjusted.
- The chain or cassette is worn out.
- There is a lot of dirt in the chain.
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, on the contrary, is the smallest.
Transmission repair steps
Repair includes adjusting the front and rear derailleurs, as well as checking the condition of the cables, chain, cassette and rollers.
- Unscrew the bolt holding the cable.
- Disassemble the shifter and remove the cable from it and from the shirts. Shirts are also recommended to be replaced!
- Clean shirts and put a drop of oil in them for better cable glide.
- Thread the new cable through the shifter and then into all shirts.
- Start configuring the switch.
- Bite off the excess part of the cable and secure the end with a special tip.
If you see that the teeth of the transfer rollers or cassettes have worn out, they must be replaced with new ones. Worn cassette or rollers rotate the chain, and the quality of gear shifting on the bike suffers greatly.
Over time, the chain deteriorates. It is recommended to keep several chains in stock and change them every 100 kilometers, because the chain deteriorates due to chain wear. Multiple chains will wear out more slowly and your cassette will last longer. You can determine the state of the chain using a special tool. It is impossible to repair the chain, you just need to replace it if necessary.
If the chain is in good condition, simply remove it, clean and lubricate. Remove excess with a napkin or dry cloth.
Cycling does not switch gears
You will need a hex wrench and a screwdriver. Place the chain over the largest sprocket in the front. At the back we put the chain on the smallest star. This is done using the speed switch, even if the settings are knocked down.
The cable on the switch is fixed with screws, which must be loosened as much as possible. There is a “drum” on the coins. It must be screwed in all the way. And then unscrew it a few turns. Rotation pulls or lowers the cable. Thus, micro-adjustments of the switch are made. But now we are not adjusting anything, but creating the necessary range for future settings.
Find the screw H on the switch. It must be signed. Turning this screw adjusts the position of the derailleur tensioner rollers relative to the small sprocket.
Your task is to match the tensioner roller clearly opposite the small sprocket.
Now tighten the cable and fix the screw. It is not necessary to pull very hard. It is necessary that the cable is simply straightened and resilient. But it’s better to fix it as it should.
Now we throw the chain over to the largest star in the back. So far, the gears may be shifting incorrectly, because the settings are not completely finished. Don’t be scared.
At the front, the chain should be on the smallest star. And the sequence of actions is repeated. Only this time, you need to adjust the position of the tensioner rollers relative to the large sprocket using the screw L. Its movement may be less noticeable, so be careful.
Now check the quality of the settings. Maybe indistinctness. To eliminate it, you need to make a few clicks with the drum. Now let’s check again the same positions where the fuzziness was.
And you also need to check the bike on the go. And to correct the indistinctness with the drum clicks. Practice will help you.
It is important to set it up especially accurately, since if the adjustment is not good enough when switching speeds, the chain can fly off or even break. The sequence of your actions will be as follows:
Use the rear shifter to shift to the middle sprocket so that the chain is not too skewed.
Next, put the chain in first gear and unscrew the bolt securing the cable.
Use the screw “L” to move the transfer frame so that the distance from the chain to the switch on the left and right coincides.
Without too much tension, place the cable and secure with the bolt.
Switch to the biggest star in the front.
Tighten the screw “H” so that the chain is again exactly in the middle of the frame.
Check adjustment results and achieve maximum shifting accuracy with the thumb on the shifter.
If the shifter triggers are too tight, loosen the cable tension.
Causes of fuzzy operation of gear switches
Cables and shirts. This is the most common problem, especially for beginner cyclists. I just wonder what a terrible state some cyclists are in.
At the end of the cable, there must be an aluminum cap that protects it from loosening. Using pliers, you can carefully remove it and unscrew the bolt securing the cable to the rear derailleur.
Release the shirt from the stops by carefully removing it from the cable. The cable itself can be left in its slot in the shifter. When he is completely naked, once again inspect for raised threads and scuffs. Spray WD40 on a rag and wipe it thoroughly.
The shirts, if they are in order, can also be used a second time. Fill them with more WD40, and gently rub there with a cable. The task is to drive out all the dirt that has accumulated during the riding period.
Here I ask Honor for such a thing. ropes and shirts do not need lubrication. Never lubricate them with thick lubricants, such as grease. Literally after a few trips on the ground, you will have a consistency in your shirts, consisting mainly of dirt.
If you need to calm the soul, then spray with Teflon spray, it dries quickly, but leaves a thin gliding layer. Which, however, will be erased after a dozen switches.
One more point. There are teflon-coated cables, such as the Shimano XTR Cable, which cost quite a lot of money. In the days of fetishism, I used only these, because of the sliding cover, the effort on the shifter is slightly less.
Unfortunately, after about a year of active skating, Teflon in places of friction is erased completely. However, these cables have a very big advantage. they come with spout stops, which effectively prevent dirt from getting in.
Returning to shirts, make sure that nowhere are too long, or vice versa, short sections, because of this, there will be increased friction in the bending places, and sooner or later dirt will accumulate there.
Bent cock. If you do not know what this part is, then here you can read a note about the bicycle cock. Sometimes it happens that a seemingly perfectly tuned rear derailleur does not work clearly, despite fresh cables and shirts.
The reason may be that during transportation, the bicycle is clamped somewhere, and the cock bent slightly. If you cannot achieve a clear gear change, then remove the cock and put it on the table.
If it is a little crooked, then you need to bend it. Do not overdo it, aluminum can give microcracks. How exactly to bend it. I will not advise. I do it in a handicraft way. I put it on the bike and pull it with my hands. Ideally, you need to edit with a special typewriter, which even takes into account the asymmetry of the dropouts.
Rear derailleur play. Move the rear derailleur towards you and away from you, keeping where the cable goes. Ideally, there should be no backlash at all, but a small free play does not represent anything criminal, especially on the initial transmission groups.
During operation, this backlash tends to increase, and then delays in switching, fuzziness, etc. begin. If everything is in order with the cables and the rooster, then with fine tuning you can overcome the negative effect of backlash.
over, many Catalans drive like this, and find it normal when the speeds are switched according to the principle of three forward, two back. Guys, this is not normal!
Any drivetrain, even the lowest Shimano Tourney, needs to work well. Do not get used to the bad, otherwise, even if you buy an expensive bike, you will get the same thing in a season or two.

How to fix defects
The rooster is the bracket to which the switch is attached. This is a known weak link, because when the switch hits the ground, it is this component that will be damaged, and the frame will remain intact, which is much more important.
By the way, there are switches that are attached to the hub axle. The mechanical strength of the system is higher, but this only applies to extreme equipment.
Titanium frames are made with non-removable roosters, as the material itself is strong. Interestingly, in English it sounds like Derailleur hangar. We also have the name rooster because of the scallop at the end.
Detachable shanks are mounted on carbon and aluminum frames. This component is cast from a large carbon aluminum alloy. Durability is low.
If the rooster is bent, then it is better not to straighten it. It will crack anyway.

Roosters have different geometry. Please be careful before purchasing. On cycling trips, participants take spare roosters with them. And usually one bike is enough for two. They do not break very often.
By the way, if the rooster is still broken, but you want to ride, then you can make a single speed:
- To do this, take a squeeze.
- We press out one of the pins. It doesn’t have to be a connector pin. He is thicker than the others. You must press out the pin in such a way that it does not fall out, but remains in the link. It is best to unwind to the end and check how much the pin came out.
- Now we shorten the chain to the desired size. It is better to move the rear wheel forward in advance. We measure, squeeze out the excess links completely. By the way, the old chain is replaced with a new one in the same way.
- We install the chain in the squeeze with the back side. We press until the pin clicks. You can skip this click. Be careful, otherwise the pin will go further than necessary.
- It is much more convenient to use a connecting pin, the long rod of which is fixed in the links, and the excess is removed with pliers.
- Now we move the wheel, so the chain will stretch a little.
Setting up your bike derailleurs is easy. You do not need to have special skills and knowledge for this. Follow the instructions and you will succeed!
Why it is not possible to set up gears on a bike?
The transmission of a bicycle consists of a dozen parts, and, to work well, each of these mechanisms must work like a clock.
It is worth just one component to go wrong and this will affect the operation of the entire transmission.
And yet, with improper operation or poor gear shifting, we often encounter the stereotype that the front or rear derailleur does not work well.
We’re in BIKE MARKET KYIV we believe, we know and have proven more than once in our own experience that good gear shifting is the result of the correct operation of not only the rear and front derailleurs, but also the steering wheel switches, the state of the chain, stars, shirts, cables and even the rear frame hook.
What components does the transmission include and what to look out for if the transmissions start to junk. After all, sometimes the problem is completely not where we are looking for it.
Most bicycles boast a gear shifting system. Such functionality will allow you to easily overcome any hill or accelerate even faster on straight roads.
The bike speed system includes:
Front and rear stars
Front stars. It can be one or there can be two, three.
Rear stars. They can be attached as on the thread, so on splines. This article will help you find out the differences between these two mounts.
The number of stars can vary from 6 to 12.
It is by the number of stars that the number of speeds on the bike is determined, by multiplying the number of front stars by the rear.
3 for 8 = 24 speeds
2 by 9 = 18 speeds
1 in 10 = 10 speeds
Excessive wear on the sprockets will result in delayed shift response and overshoot. Of course, setting up the correct shifting on such a bike will not work. It is necessary to replace these units in a timely manner.
I think it’s not worth explaining what a chain is for a long time. Chain transfers traction from the pedals and chainrings of the bicycle to the rear and, accordingly, to the wheel. Over time, any chain stretches, wears out and should be replaced. Chains are usually replaced at the same time as the sprockets. You can read more about this about Honor here.
Rear and front derailleur
The mechanisms responsible for the movement of the chain along the stars. They have many design and compatibility features. Front derailleur may not be present depending on transmission configuration.
Selection features front and rear derailleur we also consider in our blog.
Steering wheel switches
Regardless of whether they are monoblocks, shifters or duals for a road bike, their function is the same. correctly, clearly and in a timely manner to feed the cable through the shirt to the gear switches. The correct operation of this mechanism is directly responsible for the clarity of the transmissions. Many bike manufacturers underestimate this mechanism and, as a result, install more budgetary derailleurs on the steering wheel than the derailleurs themselves, and this affects the overall level of gear shifting. Buy and select these components you can in this section.
Shift cables and shirts
Do you think it doesn’t matter? But vice versa! It often happens that the problem with shifting speeds, which we are offered in the workshop to eliminate by an expensive replacement of the star switches, or the chain lies in the jacket of a broken tube clogged with dirt, or a dry cable. Ropes and shirts. these are the arteries through which the force from pressing the lever on the steering wheel is transmitted to the derailleur at the stars.
The hook on the frame is also often called the pitukh. This is the mounting location for the rear derailleur. Of the features of this part, it can be noted. it was created to break, this is a kind of fuse. Under excessive load, for example, when the switch hits the frame, the hook should burst, thereby protecting the frame and other expensive parts of the bike from damage. The deformation of the hook also affects the quality of switching, since the position of the switch along the axes will be violated and, as a result, it will be impossible to adjust the gear correctly.
If, when adjusting the speed of the bike, you cannot get a clear and well-coordinated shifting in all ranges, do not rush to sin on the speed switch, or even on the bike itself. Perhaps the problem lies elsewhere, and, often, it is.
- Your sprockets and chain are rideable, use a ruler to measure chain wear and visually inspect.
- Make sure the rear and front derailleurs are in proper condition and set correctly. The rollers of the rear derailleur are not erased, and the derailleur itself has no play in the pins.
- The gear cables are not stretched, broken, or pinched by any accessories on the bike. Shirts are clean and lubricated on the inside for a good glide of the cable, are of the correct length. there is no excess or lack of length.
- The steering wheel switches are intact and click into place. The cable feed is clear. The mechanism itself is not clogged with dirt and dust.
- The hook on the frame has the correct shape, is not deformed, is tightly attached to the frame without backlash.
