Stels Bike How To Change Speed

Stels bike how to change speeds

Surprisingly, many amateurs, buying a bicycle, do not even imagine why a bicycle needs gears and think that the more speeds. the cooler the bike. At the same time, you can often see a cyclist storming a mountain in high gear when it is very difficult to turn. Or vice versa, a cyclist who rides downhill in low gear and barely has time to pedal.

What is cadence?

To understand how to properly shift gears, you must first understand what cadence is. Cadence. is the cyclist’s cadence. Among cyclists, there are the following concepts that characterize cadence:

  • low cadence;
  • high cadence;
  • optimal cadence.

With a low cadence, that is, with too low a pedaling speed, to maintain the speed of the bicycle, you have to press hard on the pedals, muscles quickly clog, and there is a high risk of joint diseases. Low cadence. one of the causes of knee pain when cycling.

When the cadence is high, i.e. when the cadence is too high, the cyclist begins to swing strongly in the saddle. In this case, the forces begin to be spent irrationally, especially if the contact pedals are not used.

The optimal cadence is different for each rider and depends on many factors. But, on average, when driving on asphalt and ground, the optimal cadence is considered to be from 80 to 100 rpm.

The easiest way is to use a cycling computer with a cadence display to always know the exact cadence.

Gear selection

So, obviously, the gears on the bike need to be shifted so that the cadence is always optimal. Thus, the trip will not become too tiring and, more importantly, the risk of joint diseases will be reduced.

However, getting the right gear doesn’t just mean getting the best cadence. It is very important to try to select the gear so that the chain is not too skewed relative to the sprockets. It is the skew of the chain. one of the reasons for the rapid wear of the sprockets (on this topic we recommend reading the article bicycle chain care).

For example, a combination of the smallest star in front and the smallest. the rear (e.g. 1-9) is absolutely useless and can be easily replaced with another combination with approximately the same gear ratio (e.g. 2-4).

Gear shifting

Particular attention should be paid to the moment at which the changeover occurs. It is necessary to switch gears one at a time, simultaneously with the rotation of the pedals. In this case, the pedals should be pressed very lightly, in order to avoid a heavy load on the chain. If shifting with or without pedaling, there is a high risk of damaging the switches (especially when using entry-level equipment), breaking the chain, and even getting serious injury. For example, about approaching a steep climb, it is best to select the desired speed in advance.

Gear shifting should not be neglected. This will help save energy and reduce the likelihood of serious injury. For example, in low gears it is very easy to go into almost any climb, and in high gears it is possible to reach top speed. Just try and enjoy all the possibilities of a modern mountain bike!

How to learn how to switch gears correctly on a bike

The bicycle appeared as a fast means of transportation, but was designed for hardy riders and was far from comfortable. On the first “balance bikes” the rider sat on the frame and pushed off the road with his feet, even such familiar things as pedals and a saddle did not appear immediately.

Modern models, among other amenities, have a transmission that allows you to change the effort on the pedals if necessary. Next, we will consider the design and explain the principle of switching the most common type of transmission. chain transmission.

It is popular due to the relative simplicity of the device and ease of maintenance.

But the speed of the bike is more dependent on the pedal effort than the number of gears. A regular road bike with a single gear is just as fast as a high-speed road bike.

So why do you need a lot of gears on a bike? We’re going to answer this question and also find out important related points.

Why bike speeds are needed

In cars, gear shifting is necessary to reduce engine load and save fuel when driving conditions change.

Gear shifting in a bicycle drivetrain serves the same purpose: to reduce pedaling effort and reduce cyclist fatigue.

If you slowly ride several times a week along a standard route, then the load on your muscles is more or less uniform and there is no particular need to change gears.

Cadence is the number of revolutions of the pedals performed by the cyclist in one minute. For example, they say: “cadence 90”. This implies driving at a pace of 90 pedals per minute. There are also concepts such as high, low and optimal cadence:

  • Low cadence. you do a little RPM but still pedal effort. It is unsafe to ride at this pace for a long time due to the enormous stress on the heart and joints.!
  • High cadence. you pedal very quickly. The load on the legs is small, but there is little sense from such a ride. moving at a snail’s speed is not very pleasant.
  • The optimal cadence is the pedaling tempo that is convenient for you personally, it allows you to travel far and for a long time without getting tired. You ride for pleasure, but at the same time your muscles and joints are not overloaded and train endurance. For an amateur, the optimal cadence is 60-70 at the beginning of the season, and after a couple of months of continuous riding, you can pedal with a cadence of about 90-100. Athletes who do regular training are able to maintain an optimal cadence greater than 100.

Changing gears makes it easier for you to maintain a constant cadence all the way, whether you are driving uphill, with a headwind, or racing on smooth asphalt. The cyclist must constantly monitor the maintenance of the cadence. To do this, it is convenient to use a cycling computer with the ability to calculate cadence.

Bicycle Speed ​​Shifter

A bicycle drivetrain is perhaps one of the most complex mechanical parts.

And of course the most important one, because it is he who sets the bike in motion, transmitting the efforts of the legs through the pedals, cranks, sprockets and the chain to the rear wheel.

  • single speed
  • multi-speed

With the first point, everything is simple, we have a classic composition of elements: a front rear sprocket, and a chain between them. The size of the gears (the number of teeth) will determine the ratio with which the efforts of your legs are converted to transfer them to the rear wheel.

Often, manufacturers use average values ​​to make the cyclist on a single-speed bike feel confident on flat terrain, he had enough strength to conquer a slight rise and accelerate a little off the slope.

If the ratio does not suit him, you can increase or decrease the number of teeth on one of the sprockets, thereby ensuring the optimal load.

Yes, there, high-speed bicycles allow you to ride where it is difficult to climb on foot, as well as accelerate almost like a car (albeit for a short period of time).

Speed ​​bikes are much more complex and require special training to handle.

Consider the composition of the transmission on a bicycle with speeds: chainrings, front derailleur, chain, rear stars, rear derailleur, and most importantly, the bike’s gear shift knobs.

In addition to the number of speeds, they are also distinguished by the device of the switching system: planetary (gears of different diameters are located inside the rear hub or bottom bracket of the bicycle), or the classic multispeed, where all nodes are visible to the outside.

Types of speed switches

There are two main types of speed switches. external and internal shifting.

Internal switching mechanism

City bikes often use an internal gearshift mechanism that is hidden inside the rear planetary hub. Planetary hub bikes have only one chainring and one sprocket. The number of speeds / gears in planetary bushings is usually from 3 to 7. The planetary hub has a rather complex internal structure.

Pluses of planetary bushings: they withstand adverse weather and road conditions well, since the mechanism and all its parts are enclosed in a case and, as a result, are reliable and durable; you can switch speeds without pedaling.

Cons of planetary bushings:. heavy weight;. very difficult repair, impossible in field conditions.

External switching mechanism

This type of derailleur is used on most multi-speed bikes, from city to mountain bikes. Gear shifting is carried out using the front and rear derailleurs.

Front derailleur The front derailleur transfers the chain between the chainrings. The derailleur design has a moving frame within which the bicycle chain runs. When shifting gears with a shifter, the frame moves and becomes above the desired sprocket, which ensures the movement of the chain to this star.

Rear derailleur The rear derailleur is a spring-return mechanism that moves a frame (or foot) with rollers between them within the transverse axis.

In one direction, the switch is moved with a cable, and in the opposite direction, with a return spring.

When you move the derailleur, the chain passed through it is thrown from one rear sprocket to another, and the chain tensioner automatically removes the chain slack.

Advantages of external switches: simple design low weight low price high number of gears

Disadvantages of external derailleurs:. highly susceptible to adverse external factors. need for adjustment and maintenance. risk of breakage if the bike falls down. it is impossible to change gears if the bike is stationary

How to properly switch gears on a bike

No matter how many speeds your bike has, you definitely need to know how to use them correctly in order to extend the life of the transmission components and the ride does not turn into a nightmare with crackling or slipping of the chain. It is important to remember a few rules that will help make gear shifting easy, and most importantly safe.

  • Study the transmission of your bike. you should know how many gears you have; how many stars are in front and how many behind; where you need to move the shift knobs to increase or decrease the load.
  • Pedaling is a prerequisite for speed shifting. It is not enough to simply push or turn the crank, it is important to make one full turn of the front pedals so that the chain takes up the sprocket of your choice in front or behind.
  • Gear changes will only occur when no or minimum load is applied to the pedals. Even the most expensive derailleur will not be able to move the chain onto an adjacent sprocket if you are not pedaling with all your might. Therefore, practice doing it among flat areas, and over time you will be able to change gears even in the most difficult conditions.
  • Monitor the technical condition of your bike’s shifting system. When the components are not worn out, lubricated in time, and the switches are adjusted, then the gear change occurs in an instant.
  • Remember, the main thing is to cycle as much as possible using the gearshift system. The developed muscle memory will allow you to change gears in spite of the transmission or indicators on the steering wheel with light finger movements without squeaks and other troubles.

Chain placement on a speed bike

The position of the bike chain on certain gears also has some peculiarities that affect the accuracy of gear changes and the durability of the transmission parts. Some very helpful tips: never use the smallest star in the front and the smallest in the back.

The same applies to the large star in front and the large star behind. If you neglect these recommendations, a so-called chain skew is created in the transmission, which will negatively affect not only its durability, but also the efficiency of the cyclist.

The fact is that with a strong skew of the chain, the links have a detrimental effect on the teeth of the front / rear sprockets, bending or licking them to one side. Also, if the ratio of the stars is incorrectly selected, the connections between the pins and the chain links will be loosened, accelerating its wear.

Optimal cycling gear range

Depending on the training of the cyclist or the terrain on which the bike rides, you use a certain set of ratios of front and rear sprockets, which leads to their accelerated wear.

If you never include at least 50% of the speeds on your bike, it is worth thinking about optimizing not only their number, but also the gear ratio. For example, your bike has 22/32/42 chainrings and a 12-32 cassette at the back.

In this case, you most often include gears 22 and 32 in front, and only middle sprockets at the back. In this case, consider changing the cassette to a model with fewer teeth on the large side. For example, modification 11-28 or 11-25.

The same can be done with chainrings, but in addition to reducing their size, you can reduce the number of speeds by removing 1 or even 2 stars.

In addition to optimizing the load and more rational use of transmission parts, you will slightly reduce the weight of the bike;).

In the case of a lack of low gears, it is worth installing a set of rear sprockets with an increased number of teeth on the larger side or reducing the size of the chainrings.

Shifting when going uphill

Novice cyclists are often frightened by the fact that it is categorically impossible to switch uphill. But this is not the case! The rules for switching uphill are simple. If you need to slow down on the chainrings, then you should slow down the torque with the pedals, that is, make the shift as smooth as possible.

Decelerating the torque with the pedals when shifting forward gears should be because the difference between the stars on the front transmission is usually about 10 teeth, and this requires a smooth shift. Therefore, moving uphill (and just on level ground), you need to slow down the torque with the pedals, then a smooth and correct switching will occur.

If, while driving uphill, you need to switch the speed on the rear transmission, then on the contrary, you need to increase the torque with the pedals.

The only thing that you should definitely not do when going uphill is to increase the speed on the chainrings (switch from 1 to 2, as well as from 2 to 3). You can increase and decrease the speed on the rear stars when going uphill absolutely calmly, without fear that something will happen to your bike.

To be honest, personal experience will teach you how to switch gears correctly, so ride, try, train, and then you will succeed!

And remember that proper gear shifting is not only a guarantee of the health of your bike, but also maximum riding productivity in any terrain.!

Preparatory operations for setting

All the guides written on how to set up the rear derailleur on a bicycle, the first paragraph contains advice on how to properly prepare the bike for this operation.

The fact is that the speed switch is a rather thin device located in a relatively inaccessible place.

Before you begin to regulate it, it will be necessary to eliminate all the reasons that prevent the correct implementation of such a procedure.

The next stage of the preparatory work will be the transfer of the bicycle chain so that it stands on the stars of the smallest diameter, both in front and behind.

To do this, you will need to find the adjusting screws located on the switch, which are labeled: H (high) and L (low). Their purpose is to adjust high and low range gears.

Here you need to unscrew the screw under the letter “L” to the maximum value.

Before you start adjusting your bike, you need to clean and lubricate it.

After the screw is unscrewed, it is necessary to turn the drum until it stops, moving clockwise.

It also turns in a similar way, while you will need to stop without screwing about 4 turns to the stop.

One of the final steps to prepare your bike derailleur is to remove the screw that secures the cable directly to the derailleur. If it is rusty and dirty, then it will have to be replaced. In the case when it is not too worn out, namely, it is not visible that it is unraveling, clean it and lubricate.

It will be necessary to check the ease of sliding of the cable through the “jacket”, which are plastic tubes mounted on the bike frame. The fact is that in most cases the gears change poorly precisely because they are clogged with dirt. To prevent this from happening, “shirts” must be washed.

In the event that you do not have sufficient experience in operating a bicycle and do not know how to adjust the rear derailleur on a bicycle, you will need to carefully study the instructions for your bike.

If it is difficult for you to understand everything, you can contact the master who has sufficient experience in adjusting this unit.

The very same adjustment procedure must be started by checking the location of the roller designed to tension the chain, exactly above the small sprocket.

If this position is not installed, it must be set using the adjusting screw marked with the letter “H” In order to move the roller to the left, you need to turn the screw clockwise, if you need to turn it to the right. against.

Limiting scheme

Once you’ve made sure the large gears are set correctly, you can begin installing the derailleur cable. To do this, you need to thread it into the mounting screw.

If you are new to cycling and do not know how to adjust the rear derailleur on your bike, remember that the retaining screw must not be tightened to the maximum torque.

After the cable is installed, it is necessary to adjust the small gears. For this purpose, the chain is transferred to the rear sprocket of the largest diameter. After that, check if the tensioner roller is above the large sprocket, setting it in this position using the screw under the letter “L”. It is configured in the same way as above.

If your derailleur has the ability to adjust the chain tension level, adjust it. After you finish adjusting the derailleur, try changing gears on your bike while moving. They should change quickly and easily. If you feel some difficulties, then adjust the device additionally using the cable tension drum.

It will be best if you choose the optimal settings for yourself and remember them. In the future, you can set them, already knowing which position of the adjusting screws or the drum is optimal for you. This will make cycling easier and will greatly extend the life of your bike.

Correct gear shifting

Now that you’ve figured out how to set up the rear derailleur on your bike, it’s worth investigating the correct gear shifting on your bike. The fact is that if you do not “click” the gear shift knob, but approach the issue of their choice responsibly, you will significantly extend the life of your bike.

Choosing the right gear

If you try to change the speed in a stationary position of the vehicle, it can lead to failure of the transmission. Before you start shifting, the pressure on the pedals must be released.

If you need to change gears quickly, try to do so consistently without jumping over them. The fact is that when you miss a few gears, it can break the stars and the derailleur itself. In the same case, when this procedure is carried out sequentially, all units and parts of the transmission will not be damaged.

Throw position relative to the chain

It is worth remembering the following rule: if you want to overcome the hill, shift the gear up before starting to climb it. By doing this, you will not only save your strength, but also protect the transmission from damage. The same rule applies when descending from a hill.

Finding the right combination of stars

Experienced cyclists choose the right chainring for a comfortable ride, depending on the particular bike model. The most common combination for urban driving or on an asphalt road is the tandem of the 4th and 8th rear sprocket.

If you are going to go to the country or ride on rough terrain, you will need a combination of the leading star with the followers, starting with the 3rd and ending with the 6th. The same combination is useful if you want to add stress to yourself while driving on the highway.

In this case, riding uphill requires a combination of the small leading sprocket with the 1st to 3rd followers. In this case, the forces transmitted to the pedals by the cyclist will be minimal, but you will have to rotate them more often.

Frequently asked Questions

The number of speeds is determined by the quantitative combination of front and rear sprockets. To calculate how many speeds are on the bike, multiply the number of chainrings by the number of rear wheels. For example, there are 3 stars in front, and 8 stars in the back, a total of 24 speeds.

The number of speeds is determined by the number of front and rear sprockets. Modern mountain bikes usually have 3 stars in the front and 6-10 stars in the back. So a bicycle with three front and six rear sprockets will have 18 speeds, with seven rear sprockets. 21, 8. 24, 9. 27 and 10. 30. Today, the maximum possible number of speeds on a bicycle is 33.

In an ordinary way, the largest “front” sprocket is intended for physically enduring athletes on flat tracks or descents, “medium”, and the smallest one for mountain ascents. After selecting the mode, use the gear selector on the driven sprockets to select the optimum load for you. THE BASIC RULE OF CYCLING is to pedal in such a way that you can barely feel the load on the thigh (does not apply to steep climbs). Having set the leading middle sprocket, adjust the load by the followers: in the absence of wind and in a straight line, lower the sprocket (controller forward). in a headwind or ascent. pull the speed lever towards you, picking up the load.

Only change gears while the bike is in motion, this will prevent possible damage to the derailleurs. 2. Try to change gears in advance, before the bike loses speed on an uphill or in a difficult area. When the chain is under load, the shifting may not work, or pressing the pedals too hard may break the derailleur or open the circuit. 3. We recommend not to increase the gear when overcoming inclines, switch in front of the hill. If there is a descent in front of the hill, then you can properly accelerate from the hill in order to drive onto the next one by inertia. Avoid skewing the chain when the chain is on the largest chainring sprocket and the largest rear sprocket, and vice versa. 5. Try not to switch to several gears at once, make the shift in stages, after waiting for the clear operation of one gear, switch to the next. Some types of equipment provide for safe shifting of several gears at once.

We put the speed switch in the following ratio: the smallest star in the front and the largest in the back; 2. Unscrew the cable; 3. Using the low gear limiter screw, adjust the position of the frame, it should be no more than 3 millimeters from the chain; 4. Stretch the front derailleur cable slightly; 5. 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; 6. We put the derailleur on the smallest star and check how easy it is to change gears. If the switch fails, adjust the high gear limiter screw.

Set the switch to the smallest star. 2. Loosen the cable. To do this, unscrew the clamp screw located on the rear derailleur. 3. Place the front derailleur chain on the middle sprocket. 4. 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 chainring in the front should line up. Pull the cable tightly and tighten the bolt, which is responsible for fixing the tightening. 6. 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.

On average, adjusting the speed on a bike costs 100-250 rubles, it takes 5-15 minutes in time. When driving actively during the season, you may need to adjust the gear shift. 3.5 times.

The easiest gear is when the stars are in 1-1 position. In the process of riding, you should strive for a larger number, increase power and speed, however, do not resort to the maximum increase in motion often, as this is an additional load on both the transmission mechanism and the joints of the legs.

Typically a road bike will have two or three forward gears along with eight or nine cassette gears on the rear wheel, allowing for 16 to 27 possible gear combinations.

How to properly shift gears on a bike

The bicycle appeared as a fast means of transportation, but was designed for hardy riders and was far from comfortable. On the first “balance bikes” the rider sat on the frame and pushed off the road with his feet, even such familiar things as pedals and a saddle did not appear immediately. Modern models, among other amenities, have a transmission that allows you to change the effort on the pedals if necessary. Next, we will look at the design and explain the switching principle of the most common type of transmission. chain transmission. It is popular due to the relative simplicity of the device and ease of maintenance.

Most beginners focus on the number of speeds when choosing their first bike, believing that the more gears, the faster the bike goes. But the speed of the bike is more dependent on the pedal effort than the number of gears. A regular road bike with a single gear is just as fast as a high-speed road bike. So why do you need a lot of gears on a bike? We’re going to answer this question and also find out important related points.

Why bike speeds are needed

In cars, gear shifting is necessary to reduce engine load and save fuel when driving conditions change.

Gear shifting in a bicycle transmission serves the same purpose: to reduce pedaling effort and reduce cyclist fatigue. If you slowly ride several times a week along a standard route, then the load on your muscles is more or less uniform and there is no particular need to change gears. However, if you are driving over difficult, rough terrain at high speed or enjoying long rides, then it is extremely important to monitor the selection of the correct gear. To determine the desired transmission, you need to know about such a concept as cadence.

Cadence is the number of revolutions of the pedals performed by the cyclist in one minute. For example, they say: “cadence 90”. This implies driving at a pace of 90 pedals per minute. There are also concepts such as high, low and optimal cadence:

Low cadence. you do a little RPM but still pedal effort. It is unsafe to ride at this pace for a long time due to the enormous stress on the heart and joints.!

High cadence. you pedal very quickly. The load on the legs is small, but there is little sense from such a ride. moving at a snail’s speed is not very pleasant.

The optimal cadence is the pedaling tempo that is convenient for you personally, it allows you to travel far and for a long time without getting tired. You ride for pleasure, but at the same time your muscles and joints are not overloaded and train endurance. For an amateur, the optimal cadence is 60-70 at the beginning of the season, and after a couple of months of continuous riding, you can pedal with a cadence of about 90-100. Athletes who do regular training are able to maintain an optimal cadence greater than 100.

Changing gears makes it easier for you to maintain a constant cadence all the way, whether you are driving uphill, with a headwind, or racing on smooth asphalt. The cyclist must constantly monitor the maintenance of the cadence. To do this, it is convenient to use a cycling computer with the ability to calculate cadence.

How to find out how many speeds a bike has

Nowadays, almost any bicycle is equipped with a gear shifting system. There are usually 6 to 33 gears. For a road or mountain bike, 18-27 gears are a reasonable norm. Often even city or road bicycles also have gear shifters, for this type of bike 6-7 speeds are enough.

To determine the number of gears, you need to multiply the number of front and rear sprockets. For example, on the cranks of a bicycle there are 3 stars and on the cassette of the rear wheel you see 7 stars, such a bicycle has 21 gears. gears, up to 33, are rarely needed and require more careful handling, and significantly complicates and increases the cost of bike transmission.

Having considered the concept of optimal cadence, let’s move on to studying gear shifting techniques.

How to properly switch gears on a bike

We have already understood why it is important to maintain a constant cadence. But moving, for example, on the ground is much harder than on asphalt and so that the cadence on the ground does not decrease, the gear should be lowered on the ground. You need to know that shifting to one gear on the driving sprocket changes the effort on the pedals 2-3 times faster than if you shifted to one gear on the driven stars. Changing the chainrings dramatically changes the load on the drivetrain and your muscles, so they are changed much less often than the rear.

The guide sprockets set the basic pedaling pace and must be shifted when driving conditions change rapidly. The small guide sprocket is designed for uphill driving and engages well before starting the climb. The largest guide sprocket is designed for high speed performance on quality surfaces or for descents. Usually there is a third star in the front in the middle for standard driving conditions. Rear sprockets are needed to fine tune pedaling effort.

If you see a patch of sticky ground or a rise in front of you, you need to move to the smaller guide star in advance. You can do this just before the climb, and if the climb is small, you can lower the gear in advance and, by increasing the cadence, accelerate to pass the climb by inertia.

On descent, you can switch to a large guide sprocket for better acceleration.

Gear shifters are quite delicate mechanisms, and if used incorrectly, they wear out quickly. You need to know some simple rules to keep your bike’s transmission running:

A strong diagonal chain skew is harmful and contributes to the rapid wear of the chain, and also requires expensive repairs with the replacement of sprockets. How to correctly combine combinations of asterisks is shown in the figure below. The larger the chainring, the smaller the chainring at the rear should be used with it. The two smallest chainrings should be used with the largest chainring. The two largest sprockets are designed to be paired with a small sprocket in front.

As you change gears, you continue to pedal, but you should not pedal too hard. If you are shifting the front drive sprocket, then generally reduce pedal effort to avoid jerking. Do not click gears. this will damage the switches. A simple rule of thumb: you can shift up to one gear in one turn of the pedals. Some equipment allows you to change several gears at once, but for a beginner it is difficult to switch correctly in this way.

The professional shifts gears silently. Hear one slight click when switching. great, you did everything right. If the gear changes with multiple crunching, sharp crackling, then one of two things: you are shifting incorrectly, or you have a worn out misaligned transmission.

The more gears your bike has, the more carefully you should monitor the cleanliness and condition of the sprockets and chain. The limitation on physical dimensions forces designers on bicycles with a large number of gears to use thinner sprockets, chains and some other parts. All gaps in multistage transmissions are smaller, and parts are more compact, therefore, the sensitivity of this design to contamination is higher, and wear is faster.

In the end, I would like to say that if you are going to buy a high-speed bike, then you just need to learn how to use the gear shifters correctly. Indeed, when skating, you apply physical effort, and the correct technique not only gives you pleasure from the process, but also safely strengthens your body, increases your endurance. Gain experience and gear shifting will take place on a subconscious level, and you will stop wasting energy.

How to properly switch gears on a bike

There is no special science in shifting gears on a bicycle; at first glance, everything is simple. Two levers on the left, two on the right, or even just a grip-shift. what could be easier. But nevertheless, observing novice cyclists, one may notice not entirely correct and coordinated actions. But consistency when cycling is the most important thing! This is the only way you will be able to move as efficiently as possible on a bicycle, make maneuvers, overcome obstacles.

As an example, we will consider the most ordinary mountain bike (MTB) with three stars in front and 8-9 in the back.

Let’s immediately highlight the most common errors and problems:

  • Too heavy gear is a common mistake. Many newbies even say that 44 (or even 48) stars in front are not enough for them. It’s a delusion. Constantly spinning a heavy gear you are simply killing your knees. Try to keep track of your cadence (cadence) until it becomes automatic. You can even count the number of revolutions per minute for fun. If about 90-100, then this is very good. And so, gear 44-11 is enough to accelerate on the plain to

60 km / h. So try to convince those who say that 44 stars are not enough for the city. By doing this, you may help to keep people healthy.

  • Curve transmission. it is not uncommon to observe how people, without looking at the chain, include gears like 3-1.2. In this case, the chain goes to bend, its wear increases, at the wrong moment it can simply fly off. The optimum chain position is when it passes from the chainring to the rear with minimal skew. So be sure not only to make it easy to twist, but also the position of the chain.
  • Switching under load. so even fragile girls manage to break chains, what can we say about healthy men. And what a crunch at the same time. When shifting, reduce the load on the pedals to a minimum, just rotate them with ease until the chain jumps to the desired sprocket. Therefore, it always makes sense to assess the situation, possible obstacles and change gear in advance.
  • Chain biting is when the chain is pulled up by the chainrings when shifting. An unpleasant situation in which the nib near the carriage assembly may be severely scratched. This could be due to cogging on the star, dirt, improper assembly and setup. This is another plus to why you need to watch the shift, and not just mindlessly clicking the shifters. All movements should be smooth, even airy.
  • Chain skipping. for example, you put a new chain on an already similar cassette (by the way, the chain resource
  • 1500 km). As a result, when the load on the pedals increases, the chain slips and the pedals fail unpleasantly. This must be taken into account and travel more carefully until everything gets used to it. Even for a fairly strong cassette, the rubbing period is about 200 kilometers.

    If you are new to the saddle, pay a lot of attention to pedaling, shifting, try to work with both the front and rear derailleurs. Try to choose a gear depending on the maneuver being made. For example: you slow down, but you will need to accelerate for this. Shift the gear lighter even when braking, then it will accelerate faster.

    The clarity of gear shifting is highly dependent on the technical condition of the bike components. Monitor and, if necessary, replace the cables and shirts in time, the rear derailleur rollers, the switches themselves, the drive elements. the chain, cassette, front sprockets.

    Forming a skill: how to switch gears correctly using the example of a Stealth bike with 21 gears

    Competently switching is to choose the appropriate pace of the ride, at which the cyclist will spend the minimum amount of energy. How important this really is is clear from the following theses:

    • Optimum crank speed ensures joint integrity.
    • Acceptable cadence is the key to effective muscle work.
    • Exemplary speed preserves plant life of components.

    You can learn and learn how to shift gears correctly on a mountain bike only after mastering its high-speed design. So, on any Stels Navigator model the following are installed:

    • 3 stars in the front and 7 stars in the back.
    • Handlebar shifters.
    • Rear and front derailleurs, which are regular metal frames attached to the frame.
    • 2 cables connecting the steering gears and frame spreaders.

    The process of regulating the position of the chain between the stars with the help of frames is called switching. It is carried out by working with shifters. The latter are of two types: trigger (with levers) and pin (rotate). They are installed on the steering wheel in two copies:

    • The left one is responsible for the operation of the front transmission.
    • The right moves the rear chain spreader.

    On the shifters, there are numbers showing the number of the current star. The asterisks are numbered from left to right. The shifting process itself consists in pressing or rotating the levers. When pressed (trigger shifters):

    • Upper Left Stick. Resets to smaller chainring in 3-1 sequence.
    • Lower Left Arm. Folds over to the large front sprocket (1-3).
    • Upper Right Handle. Throws to parts with fewer teeth located at the back (1-7).
    • Lower Right Lever. Moves the rear frame towards the large stars (7-1).

    The gear selector mechanism is similar on pin switches. By rotation, the cable either loosens or stretches, pulling the frames behind it.

    If the device is unpacked and assembled, the method for adjusting the brakes has been completed, the algorithm for how to switch speeds on a Stealth bike is clear. you can ride. When moving, it is worth choosing the gear ratio correctly, excluding chain distortions:

    • Big star. Used when driving from slopes and no wind. Cooperates with rear set 5, 6, 7.
    • Medium asterisk. It is used when starting, moving along a flat road and a well-groomed intersection. Interacts with the rear block 3,4,5.
    • Small star. It is used when riding on slopes, rough rough terrain, wetlands, viscous mud, sand, thick grass. Spins optimally with rear sprockets 1 to 3.

    We consolidate knowledge or how to change gears correctly on any mountain bike without harming people and equipment

    Awareness of the gearshift mechanism is not enough to operate a bike confidently and safely. It is also worth familiarizing yourself with the tips on this matter:

    • The chain can only be thrown during movement. If the position of the frames was changed on a stationary bike, you need to spin the pedals at idle (raise the rear wheel).
    • Use the transmission only with an unloaded chain. In other words, to move the links of the chain drive exclusively with fast rotation of the connecting rods, but not at the start or under load. This is fraught with the fact that the actuators can break and the chain break. And indeed, with a lot of effort on the pedals, there is a great risk of not switching at all when the corresponding command is given.
    • Do not transfer multiple stars at once. It only takes one click to reposition the frames. In this case, the clarity of the transmission is ensured.

    A lot has been said about the need to avoid skewing the chain. Why is this necessary? It’s simple: when the chain is in the position, for example, a large sprocket in front and a large one. at the back we have obvious wear, which is expressed in additional grinding of flexible links. By the way, a typical mistake of drivers who ignore the technology, how to properly change gears on a high-speed mountain bike with 18 and more speeds. use the rear sprockets in the whole.

    Note. The chain must be washed with, say, a high pressure washer and lubricated. If it slips on the cassette, it must be changed along with the rear sprockets.

    Another important aspect is to select the speed of the transmission so that pedaling is easy. The optimal cadence verified by cyclists is 80-90 rpm. To measure it, you can use bike computers, for example, CatEye Strada Cadence. Be sure to drink during pokatushek. These two rules will save your knee joints.

    • The main goal of the transmission is to provide an easy pedal travel (80-90 rpm) in any driving situation.
    • Switching is carried out by pressing or rotating (trigger or pin shifters, respectively).
    • The selected gear is displayed on the steering wheel shift control.
    • When traveling around the city on a 21-speed bike, it is optimal to use the middle chainring and one of the three rear sprockets: 3, 4, 5.

    How to change the speed on the car? Tips for novice car enthusiasts

    • We release the gas and smoothly press on the clutch. It is important that the first pedal is turned off and the second is depressed with minimal waiting. In practice, you will catch this moment.
    • We translate the gearshift lever according to the diagram drawn at the top of the handle to the desired position. But before changing the speed on the machine, you first need to move the handle to neutral position and after 1 second engage the desired gear. This is done in order to reduce the load on the transmission gears.
    • Next, smoothly release the clutch and press on the gas a little.
    • After releasing the clutch completely, apply pressure to the right pedal.
    • Continue until the next gearshift.

    First you need to understand at what point you need to switch from a low gear to an upshift. The tachometer, speedometer and, of course, the sound of the engine always help us in this. We will not pay special attention to the noisiness of the latter, but on the readings of the dials. just the opposite. The question of when and how to change gears on a car is really nothing complicated. If the tachometer needle has left the green scale and slowly starts to turn into red, then we switch to a higher gear. For convenience, you can also use a speedometer. In this case:

    How to change gears correctly

    • release the gas pedal;
    • reduce the speed of the vehicle by pressing the brake pedal until the corresponding low gear;
    • fully squeeze the clutch;
    • engage the appropriate gear with the gear lever (do not hold the lever in neutral);
    • release the clutch pedal smoothly and simultaneously increase the fuel supply using the accelerator pedal.

    You need to travel a certain distance in second gear to feel confident and comfortable at that speed. Remember to look at the road while driving, not at the instruments or your fellow traveler. Try to control movement on the sides, behind the car, monitoring the situation with the help of side mirrors and rear-view mirrors. It is necessary to learn how to timely notice traffic signals, road signs, markings on the road, means of organizing road traffic (bumpers, posts along the road, barriers, etc.). Be sure to try to stop and pay attention to the braking distance. this is the distance that the car travels from the moment it starts braking until it stops.

    How to change gears on a car

    Before you know how to change gears on a car, you need to understand how a manual gearbox works. It consists of: a primary shaft connected through a clutch to the engine output shaft, an intermediate shaft with a set of gears with different gear speeds and, finally, a secondary, rigidly connected to the driven (cardan) shaft of the car. All this set is placed in the case. the crankcase. The gears are lubricated by spraying. The grade of oil belongs to the type of transmission and is usually class SAE30 / 85-90W.

    Then you need to pick up a speed of about 15-20 km / h, quickly and smoothly squeeze the clutch with your left foot, move the gearbox handle with your right hand to the 2nd position, while simultaneously throwing off the gas with your right foot, release the clutch and add gas. If it is necessary to switch from second to third speed within 40 km / h, the motor starts to “howl” slightly. In this case, it is necessary to repeat the manipulations described above. In short, it looks like this: in turn: the clutch is squeezed out, then the gas is released a little, the manual transmission handle is moved to the 3rd position and the clutch is smoothly released and gas is added. The transition to the 4th and 5th speed is identical to the previous ones.
