How to Shift Gears on a Bike 24

How to shift gears on a bike

When choosing a bike, beginners pay primary attention not only to its design, but also to the number of available speeds. At the same time, they do not understand the principle of their work and believe that the more they have in stock, the better. Of course, if it is great without any speed at all, then this is no good. it is physically very difficult to ride it and reach some record indicators or pedal for a long time without the appearance of chronic fatigue. Great with the ability to shift gears opens up ample opportunities for the cyclist.

Benefits of Timely Gear Shifting

Timely and correct gear shifting on a bicycle will not only allow you to ride for a long time without much fatigue, but also climb slides that ordinary bicycles will not be able to do. Competent and skillful gear shifting on a bicycle will ensure the following:

  • The work of the cyclist’s muscles will be at maximum efficiency, their efficiency will be really very high;

shift, gears, bike

  • The wear of all parts of the bicycle transmission will be significantly reduced or even completely reduced to nothing. The chain, sprockets and the gearshift mechanism itself will last much longer than usual;
  • The health of the cyclist himself. The load on the knees is significantly reduced, the health of which the cyclist must and always need to maintain.

Correct switching of bicycle speeds. we do everything correctly

An experienced cyclist, like a motorist, changes gears very quietly, smoothly and gently. The inexperienced will ride in jerks, the gears will jam, the bike mechanisms will creak and crunch. the ride will turn into a battle with the bike without becoming a pleasure. There are some general guidelines for gear shifting that are recommended for both beginners and experienced cyclists:

  • The process of gear shifting itself should be carried out only while driving. It is highly undesirable to do this business while standing still, as the chain mechanism will break. If you have to change speeds on the spot, you need to raise the rear wheel of the bike and pedal. And only then switch. Most often this is done to lower the gear, in case of forgetfulness, lower it while driving. There is an exception. special planetary hubs, but they are still installed on a very limited number of bicycles for city walks;
  • You need to switch at a time when the load on the circuit is minimal. At the same time, this must be done in a timely manner, without waiting for a decrease in speed. The pedals should rotate easily and naturally;
  • Before changing gear, you need to stop for a couple of moments and not pedal. At all. Only after changing the speed can you start their smooth promotion. Gradually you will understand when the right moment comes and will do everything automatically, correctly;
  • It is very undesirable to switch several gears in a row at once, everything must be done measuredly, gradually and in order. Of course, in this case, no catastrophe will occur, but the switch will fail so sooner or later;
  • It is advisable not to shift reverse and forward gears at the same time. The chain will very easily get stuck between the stars and the mechanism will come to an end;
  • When changing gears, make sure that there is no particularly large chain distortion. For example, if your bike has three stars in front and eight in the back, then it is advisable not to switch like 1-8, 3-1, 3-4, and so on. This can damage the entire switching mechanism, a wedge will occur.

It will be useful for beginners to find out, and for experienced cyclists to remember that the average working star in the unit is usually considered, therefore, most often the reverse speeds can be switched without compromising the speed of the movement itself. The pedaling efficiency will also remain the same and the chainrings will not have to worry about. Similarly, but vice versa, you can change gears from higher to lower. If you change gears on a bike exactly as described, then the above three most important advantages will always be with you.

Cadence. what is it and how is it related to gear shifting

The word cadence refers to the cadence of a bicycle. It is quite logical that the cadence is directly related to the speed the unit develops. The cadence must be maintained at a certain level. usually about eighty revolutions per minute (plus or minus ten revolutions). With the correct cadence, you will use your strength more evenly and will be able to protect your knees from unnecessary dangerous loads.

And some recommendations from professionals:

  • If you are driving through an area with mud, then turn on an overdrive. so the probability of getting stuck will be much lower than usual;
  • If you are driving on sand, then it is advisable to put a lower gear. otherwise, when the speed decreases, turning the pedals will be very difficult. Although, if the section with sand is short, you can safely pass it in high gear, here the inertia force will help out;
  • Analyze the rise before climbing it. It is necessary to carefully review all areas where the gear change will be optimal. On the highway or off-road, always plan your route slightly ahead of time and calculate gear changes in advance;
  • Regardless of your physical condition, always maintain a single cadence.

Any cyclist should know how to properly switch speeds on a bicycle. When they buy a bicycle for children, they are always interested in how many speeds it has. And the higher the number of speeds, the better. But experienced cyclists know that the speed of a bicycle depends on the rider, or rather, on the work of his muscles. And the art of competently changing gears is the quality of cunning professionals, which allows you to squeeze the maximum possible resources out of the car in rough terrain.

It used to be simple: the road bike had one speed. Therefore, on the plains, everything depended on the skills of the cyclist himself, and to ride in the mountainous terrain, one had to adapt to the terrain conditions: while riding downhill, the cyclist accelerates the car as much as possible in order to enter the next mountain by inertia. If the ascent is protracted, then the cyclist rides uphill until he can pedal. Then he dismounts his bike and proudly walks alongside to the top to continue his journey down again.

Modern bicycles have two sets of gears. front (sprocket) and rear (driven sprocket). It is extremely important to learn how to choose the right gear depending on the nature of the ride. First, you need to learn a few simple rules for shifting gears:

  • There is no need to change gears when the bike is stationary. This could damage the switches.
  • You should change gears even before your speed drops in front of difficult-to-pass areas (for example, sand or loose snow) or on the rise.
  • You don’t have to pedal hard when changing gears. Switching is easiest if there is no load on the circuit and there is a speed margin.
  • When switching, you need to make sure that the chain is not strongly skewed. That is, you should not use a large chainring and a large rear sprocket. In reality, you should use the following gears: with a small star in front to 4-5 stars in the back, from the second front. from 3rd (2nd) to 6th (7th), and with a large front. from 5th to last 8th (9th).

Now let’s talk about choosing stars. It is impossible in advance to accurately match a particular gear to specific road conditions. Of course, there are many formulas, graphs and tables, but most of them are calculated for road bikes, fair weather and smooth asphalt. Should the conditions change, and all the calculations are down the drain. The choice of gear depends on the road or lack of it, the slope of the track, temperature, soil conditions, tire pressure, wind, the physical condition of the cyclist, adrenaline and blood sugar levels. There are other criteria that cyclists can be guided by. One of them is cadence. It is known that the optimal cadence when driving on a horizontal surface. for example, on road bikes. is an average of 95.115 rpm, while for cross-country riders this value will already be 70.90 rpm. But for amateurs and cyclists, this is just a guideline, not a rule. There is no need to try to start immediately from high gears, first in low gears we warm up the muscles, unwinding to optimal gears. When choosing a gear, as in any business, the cyclist needs to stick to the “golden mean” and not go to extremes. A slow pace of driving in large gears is very detrimental to the condition of the knee joints. Pedaling too often will reduce riding efficiency and fatigue more quickly. In difficult road conditions (driving on mud, sand, grass or snow), the gears are lowered due to the need for a torque reserve. The technical capabilities of the switches do not always allow the chain to be dramatically shifted from small stars to large ones. For mountain hikes with backpacks, a set of chainrings, for example, 48, 38 and 28 teeth, is usually sufficient.

When driving against the wind or uphill, you need to switch to “lower gears” close to 1: 1). This set of gears increases cadence but decreases speed. When driving on flat terrain, the gear ratio can be 4: 1 to maintain speed. In a motorcycle race, a speed of over 100 km / h can be achieved. In these record-breaking rides, cyclists use a gear ratio of 8: 1 or more. However, usually the muscle strength of the legs is not enough to spin such gears from a place. Even athletes do not use gears greater than 5: 1, but rather increase their cadence.

Switch device

In order to properly use gear shifting, you need to understand how it works. The principle of operation of the transmission of a bicycle is based on the same gear ratio from school physics. This is how all manual transmissions work. For simplicity, if a small star turns a large one, this is a power low gear (i.e. you can go up a hill without effort), and if a large one turns a small one, then the opposite is true. It will be a high-speed gear or an overdrive.

Accordingly, on a bicycle we have an open transmission. There are large stars in front (2-3 pieces in the standard case), and behind a cassette of 5-8 stars. It remains to throw the chain between them. For this, the gear selector is used (both front and rear derailleur).

The movement of the chain through the blocks is provided by the front or rear derailleur, and the derailleur is connected to the levers on the bicycle handlebars (shifters). The right trigger usually adjusts the position from the front, the left one from the back. By combining different positions of the chain on the sprockets, the cyclist varies the speed of the bike, and with this changes the gear ratio, and therefore the muscle effort required to obtain a result. Shifting on the front block allows you to radically change gear ratios and quickly jump between the main modes. Moving around the cassette makes it possible to more accurately select the desired ratio.

How to shift gears on a bike

If you’ve never ridden a high-speed bike before, the presence of handlebar levers and a row of sprockets on the crank arm and cassette are sure to ask you a lot of questions. In addition, sometimes happy owners of a bike with speeds or a simple mountain bike hardly understand why speeds are needed at all.

On a flat road with good coverage, it is quite possible to do without gear shifting. The cyclist simply selects the optimal chain position and a comfortable gear ratio. The speed of the bike here is determined by stubbornness and physical form. But it’s better to learn to play with gears even here, choosing the optimal cadence depending on the angle of inclination and road conditions. The preferred gear ratio for most beginners is 2-5 or 2-4.

To drive up a hill, drive through sand or snow, the speed ratio alone will not be enough. On bicycles at the same speed in such a situation, everything depends only on the intensity of pedaling, the strength of the cyclist’s muscles, riding technique and the ability to “pull” in time.

The presence of gears greatly simplifies this process, but only on condition that the speeds are changed correctly and in a timely manner. In addition, you shouldn’t forget about the health of your knee joints. It is much more useful if the knees do not overload on difficult areas, but do more movements. i.e. cadence more.

There are some simple guidelines:

Avoid distortions

There is such a thing as prohibited transmissions. When changing gears while riding, make sure that there are no strong distortions of the chain. If the front of the chain is on the outermost sprocket, and at the back. on the extreme inner (or vice versa), then, in addition to the likelihood of the chain slipping, there is a danger of its premature wear and damage to the mechanism. The more parallel it is in relation to the frame, the better. Optimal combinations of front and rear chain positions can be summarized as follows:

Do not step on the pedals

This rule is especially important for chainrings. This group is responsible for the upper part of the chain, which stretches as much as possible during movement. If you do not relieve the pressure on the pedals and change the position of the speeds, the chain may break.

How to properly shift gears on a bike?

On modern bicycles, a multi-speed transmission is most often installed. It is needed to make it easier for you to pick up speed or go uphill.

Experienced cyclists shift gears without even thinking. Over time, the brain and body become so familiar with this process that they perform all actions automatically.

But it takes months, if not years, to become an expert cyclist. And it is desirable that during these months the transmission remains safe and sound. After all, the more complex the mechanism, the easier it is to damage it. What can be more complicated in a bicycle than a transmission? Therefore, remember a few simple rules that will help you reach an advanced level of skiing without significant losses.

  • The first important rule is to change gears only while driving. Only then will the chain jump to an asterisk higher or lower. If you do this during a stop, then, most likely, you will not be able to change gear, and during the start, the chain may fly off or hang in an incomprehensible position.
  • During gear shifting, the chain must not be heavily stressed. Do not press on the pedals, but rotate them slowly, trying to catch the moment when the chain is fully moving higher or lower. Otherwise, you run the risk of being left without a chain or knocking down the tuning.
  • It is theoretically possible to switch gears on a bicycle while climbing uphill. Cyclists on the Tour de France do this all the time. But let’s not take an example from them. At least until we have a top hitch and a few medals in regional competitions.
  • The same cyclists mentioned in the previous paragraph somehow manage to switch several gears at once! But if you are not striving to overtake your rival in the fight for first place, then it is better to do it in stages: click-work of the transmission-complete movement of the chain-click-work of the transmission and so on.
  • Due to some laws of physics and mechanics, large distortions of the chain must not be allowed. In other words, if you have the first speed in the front and the last one in the back, this is bad. You can reduce the efficiency of your efforts or the accuracy of the transmission.

The most popular drive is three stars at the front and eight at the rear (example. Author Stratos ASL 2015). The largest sprocket in the front is well suited for driving on a level, straight surface without too many obstacles and headwinds. It matches the rear sprockets from the eighth to the fourth (large).

The middle chainring will help out in heavy traffic, bad asphalt, dirt road and other imperfect surfaces, as well as in strong winds. With it, you can use any reverse gears, dexterously maneuvering between cars or houses.

Finally, the smallest star in front turns on when we have to overcome a slight rise or ride through mud, sand, tall grass. Combine it with rear sprockets 1 to 5 (small).

Whichever gear you are in, the pedaling speed should not drop below 60 rpm (this is considered ideal cadence). Experiment with the transmission on different road surfaces, but try to pay less attention to the switches themselves. your eyes should be fixed on the road. Over time, you will stop thinking about it altogether and one fine day you will catch yourself choosing gears on the machine.

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.

Please 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.

Please note: after performing specific manipulations to repair bent / deformed parts, do 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.!

Adjusting the Limitations and Quality of Chain Hopping on the Front Derailleur

The next part of tweaking the transmission is adjusting the front derailleur. The work includes debugging the accuracy of the chain travel limits using the H and L-screws, as well as the speed of the chain transition when gears are engaged.

If it was correct to start from the rear with the high gear limiter, then here first the position of the roller is adjusted from the side of the lower gears:

  • The chain is transferred to the “lower front, higher back” position.
  • The cable is detached from the derailleur.
  • By turning screw L, the smallest possible distance of the chain from the inner frame is achieved.
  • The cable is put on and pulled by the drum adjuster.

Setting the correct limiting with screw H differs from the L-setting by reversing the chain position on the stars (smallest in front and largest at the back) and approaching the chain to the outer frame of the derailleur.

How to Adjust the Accuracy and Response Speed ​​of the Front Derailer:

  • We turn on the top gear from the front.
  • We consistently transfer to lower gears.
  • We tighten the cable if the chain is tight and slow.
  • We reach the lowest star and switch in reverse order.
  • We release the tension by turning the drum if the chain does not go to higher gears.

Tightening and loosening the cable with the drum adjuster

When tuning, you should achieve fast operation of the switch on all stars. Initial position of the chain at the rear: when checking for insufficient tension, the smallest sprocket, and for excessive tension, the largest sprocket.

It is on this simple principle that the front and rear parts of the transmission are debugged. Quality parts such as shimano rarely need adjustments and last a long time afterwards. In any case, it is quite possible to fix the imbalance problem with your own hands without going to the workshop.

Operation: how to adjust the reverse speeds on any type of bike

Before starting the process of adjusting the rear derailleur, you should familiarize yourself with its configuration. The standard module has five adjustment elements:

  • nut securing the cable;
  • cable tension drum;
  • limit screw for the lowest gear (Low);
  • limit screw for the highest gear (High);
  • chain tension screw.

The method “how to adjust the reverse speeds on a bicycle” consists of three stages.

Why randomly switch gears

The reason for this phenomenon may be the condition of the cable that passes under the carriage of the bicycle frame. When pedaling, the frame flexes in different directions under load. These deformations affect the tension or loosening of the cable with each subsequent revolution of the pedals.

How to use the gears on your bike properly / How to use your bicycle

With a large friction of the cable in a certain area, one-sided jerks occur. the tension of the cable, in which it does not return back during the opposite movement of the pedals. The best way to solve this problem is to lubricate the cable.

If, nevertheless, the above methods cannot help, then more drastic measures must be taken. For example, to make the movements of the cable predictable and correct, you can install additional rollers along which the cable will pass. This will help fix the problem.

There are some simple guidelines:

You can only change gears while the bike is in motion. In a stationary state, the shifter will also work, but the position chain will not change. Then, after the start of the movement, there will be a sharp jump from one star to another. This could cause the chain to jump off or become stuck between the sprockets.

Switching speeds is possible only when there is no load on the pedals. When climbing up, overcoming irregularities or quickly screwing in, the load is maximum, and it is too late to fold the gears. This should always be taken care of in advance. For example, if you see a rise in front of you, then you need to switch at least a few meters before it. Otherwise, the mechanism may simply not work. In addition, there is a possibility of damage to the stars and breaking the chain. However, you can also switch on the mountain. High quality equipment allows you to do this. But both with an expensive quality body kit and with the simplest switch, there is a way to switch on the mountain. It is enough to accelerate the bike until inertia appears, then release the pressure on the pedals and, while rotating the pedals while the bike is moving by inertia (or is at the balance point), change the gear. In this case, switching will not cause difficulties.

For the same reason, on inexpensive switches, you cannot simultaneously throw off or raise the gear by several values ​​at once. This needs to be done in stages: click. moving the chain. several turns of the pedals. click- and so on. In case you are trying to throw over several stars, you will need to make sure that the chain is in the right position and only then make efforts.

There is such a thing as prohibited transmissions. When changing gears while riding, make sure that there are no strong distortions of the chain. If the front of the chain is on the outermost sprocket, and at the back. on the extreme inner (or vice versa), then, in addition to the likelihood of the chain slipping, there is a danger of its premature wear and damage to the mechanism. The more parallel it is in relation to the frame, the better. Optimal combinations of front and rear chain positions can be summarized as follows:

  • 3. large front. 4-8 back
  • 2. middle front. 3-6 back
  • 1. small front. 1-3 back.

Correct chain position

The main rule for the position of the chain is its parallel arrangement relative to the plane of the sprockets, without kinks and distortions. If, sitting on a bicycle, look from above at the chain in the transmission, then you can see its location:

  • The front and back of the chain lie parallel or under a slightly noticeable bend. these are the correct speeds;
  • There is a sharp bend between the front and rear of the chain. this is a skew. It will be visible when you set the first speed at the front (left shifter) and the highest at the rear (right shifter). This ratio is not correct and may damage the bike chain and mechanisms.

With feeling, with sense, with arrangement: how to change gears correctly

How can you tell an experienced cyclist from a beginner, even if they ride the same bikes at the same speed? Answer: by ear.

Experienced in the knowledge of how to properly change gears on a bicycle. This happens to him without a single sound. The beginner has a terrible grinding noise. What is the reason?

Answer: Inexperienced cyclists shift gears without releasing pedal pressure. This is bad: this is how the resource of the chain and transmission stars is reduced. And sometimes such a shift even leads to breakage of the gear derailleurs.

How to properly shift gears on a bike?

  • First you need to slow down your pedaling. Slow down so that they spin “idle”.
  • Change gear.
  • Continue pedaling at idle speed. As soon as you feel that the chain has jumped to a new star, you can pedal again in your usual mode.

For more information on how to shift gears on a bike, see the following video:

Do not skew the chain. That is, if you are driving the chain on the smallest chainring, it should not be on the smallest chainring at the same time. Conversely, when on the largest chainring, the chain should not be on the largest chainring. This also reduces the service life of the chain, stars and the gearshift system as a whole.

How to Shift Gears on a Bicycle: A Visual Aid

Do not shift reverse and forward gears at the same time. During such a switch, the chain may jam.

Switch to the desired gear well in advance. For example: there is a rise in front of you. Seeing it, shift into the desired gear a few meters before you feel the lean angle. Otherwise, you will begin to switch at the moment when you apply strong pressure on the pedals. This is bad. Why is the answer above.

Shift gears a few meters before lifting

Take care of your bike. Gear shifters must be clean and free of dirt. The same applies to the chain (learn how to clean it here). Only in this state will they work correctly and last a long time.

Take care of your bike. and it will serve you for a long time
