How To Determine The Number Of Speeds On A Bike

How to determine the number of speeds

The nominal number of speeds is determined by the combination of front and rear sprockets. For example, if a bicycle has 10 rear sprockets and 3 front sprockets, then the nominal number of speeds will be 30, and if there are 9 sprockets behind, then 27. However, there is one caveat. the actual number of speeds that can be used will be less. This is because due to skew and incorrect chain tension, all possible sprocket combinations should not be used.

What are we for

Switching the speed on the bike, we throw the chain from sprocket to sprocket and change the cadence, that is, the cadence, taking into account the force required to press them. By varying the gear ratio between the pedals and the wheel, we can change the pressure on the pedals. In order for the energy to be evenly distributed during rotation, we turn on different gears.

When riding in rural areas, on steep inclines or descents, the cyclist is forced to pedal at high speed. One, two, three times this can be done without risk to health, but constant experiments on the body can lead to serious problems with blood vessels. What can be done? Turn on the lowest possible speed. The bike will go slower, but the load on the muscles and blood vessels will decrease due to the pedaling speed.

When descending, the speed, on the contrary, will need to be increased. You have to put in a little more effort, but the bike will accelerate and run smoother. For driving on flat surfaces in the city, average speeds are usually chosen, while the chain is stretched evenly, and the load is distributed between muscle groups.

It turns out that the multi-speed system passes the following tests with dignity:

  • Climbing steep hills;
  • Abrupt descent from the hills;
  • Overcoming high barriers;
  • Driving on sand, mud, off-road.

Summarizing what has been said, we can summarize: transmissions are necessary to save muscle energy in different parts of the path. That is why the question of the number of speeds directly depends on what bike and on what roads you are going to ride.

What does “switch gear” mean??

Gear shifting is a chain transfer from one chainring to another. This changes the gear ratio and the effort “on the pedals”.

Why Bike Speed?

Primarily for convenience. Gears allow you to save power and choose a comfortable pedaling mode Based on:

  • Road relief (plane, ascent or descent, acceleration or smooth braking)
  • The quality of the road surface (highway, Country road, mountains);
  • Required speed;
  • Weather (tail or head wind)
  • Rider’s physical condition.

How many bike speeds do you need and how to switch them?

A common but diminishing misconception is that the more speeds the better.

Need to ask the question which is better? Or who is better?

Today you can find solutions from 1 to 33 speeds. In various combinations: 1 × 7, 1 × 11 2 × 9, 3 × 10 (the first number is the number of stars in the front, the second number is the number of stars on the back of the cassette). Multiplying these numbers, you get the maximum number of speeds that can be “turned on” while riding.

Why Bike Speed

Whether such technical moments are needed is up to the owner himself. If the bike is used exclusively for recreational purposes, for rare and close trips, it is better to use conventional models, but when the owner of a two-wheeled car plans frequent and long trips to the track, it is worth considering purchasing a product with such equipment. Switching is provided to maintain certain load modes and in the terminology of cyclists, to denote this phenomenon, the word cadence appeared.

It is customary to call cadence the frequency of pedaling that occurs over an equal period of time. It can be conditionally divided into three groups: low, high and optimal.

  • Low. the load on the athlete’s legs is increased, because K. You have to press the pedals very hard to spin the wheel at a low frequency, and this riding style can also be used when going downhill;
  • High. the rotation is very fast, but the efficiency is low. for a certain period of time a very small distance is covered, this option can be useful for burning excess fat accumulations;
  • Optimal. a reasonable ratio of load, frequency of movement and energy consumption to obtain the most beneficial result.

Optimal gear shifting

In order to avoid skewing and slipping of the chain, it is recommended to change speeds as follows:
The first chainring works with chainrings in combinations 1-1, 1-2, 1-3 and 1-4.
The second chainring works with chainrings in combinations 2-4, 2-5, 2-6 and 2-7.
The third chainring works with chainrings in combinations 3-6, 3-7, 3-8 and 3-9.

As a result, a bike with three front and nine rear sprockets is rated at 27 speeds (39 = 27), but in fact it will only have 12 speeds. And that’s enough for trips across terrain with any terrain.
It should be noted that adhering to this scheme is not at all necessary, but when using the optimal combinations of switching stars, chain wear is significantly reduced.

Switches

In order to switch speeds, just return or pull the switch on the steering wheel. Switches (they are also shifters) are of several types:

  • Rotational (the speeds are switched by turning the handle)
  • Lever (on the steering wheel there are special levers for switching speeds)
  • Griptshift (the handle should be rotated away from you or towards you);
  • Finger levers (one lever changes the speed down, the other up).

All these devices cost about the same, the latter were invented recently and will cost you a little more.

It’s all about the stars

The number of views directly depends on the type of bike. Usually there are two leading stars on Road Bikes and three leading stars on mountain bikes, but there are exceptions. At the same time, there are additional stars: for example, 3 and 7-10 gears are installed on road bikes on the front and rear wheels, respectively. To determine the total number of gears, you need to multiply the number of views on both wheels. It is easy to determine that the number on modern road bikes ranges from 21 to 30. City bikes are often equipped with five gears in the back and two in the back. Ten speeds will be more than enough for them. Most modern city bikes are equipped with seven starter gears. Do NOT need a lot of speeds and children’s bikes.

How many speeds are there on a bike

How to switch gears correctly?

In order for the bike to serve you faithfully for many years, it is important NOT to neglect some important rules.
First you need to select the correct forward gear, and then adjust the gear with the rear derailleur.
The first gear is optimal for uphill, sand and mud riding to save your strength and energy.
Second gear. for driving on uneven terrain with small inclines.
Third gear. for city and smooth asphalt.
By choosing the right gear, you can avoid fatigue during long cycling, avoid knee pain and get maximum pleasure with minimum effort.

Switching gears is easy, the main thing is to do it right:

How to determine how many speeds on a bike

Once upon a time, everyone rode bicycles with a single gear and did not even think about what could be different. Today the market is ready to offer many models with different numbers of gears. What is the difference and is there any point in overpaying for their quantity. let’s figure it out in this article.
First and foremost, gear shifting provides comfort when driving over rough terrain. Thanks to the ability to change gears, it is easy for the cyclist to climb the mountain and can relax and gain good speed while descending the mountain.
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.

Single speed bicycles. How to properly change the transmission control

For more than two hundred years of the creation of a two-wheeled friend, its appearance and equipment have changed significantly, there have been many inventions of devices that facilitate movement. Modern products boast both lightweight frames and the presence of various shock absorbers, and of course, the ability to adjust the pace of travel through the adjustment of the transmission.

We have already understood how many speeds there are on a bicycle, but we will try to figure out how to use them correctly. The amount does not help much to increase the pace of movement, but it can make the trip more efficient and comfortable.

The purpose of this equipment on the bike has a certain logic. So, to maintain movement at an increased pace, a large leading star is best suited, with a prolonged mountain climb, use the smallest, medium size allows you to maintain an optimal walking option.

Switching should be done according to the following rules in order to avoid breakage of this thin instrument:

  • Do not bend the chain. Misalignment leads to premature wear of both the chain itself and the stars;
  • Mode change occurs with rotating pedals. At this moment, you cannot make maximum efforts, but press with medium effort;
  • All rotating transmission parts must be kept clean;
  • Can’t use two switches at the same time.

If you have opted for a bike equipped with Multiple Sprockets, then try to take into account our recommendations, and adjust the change in riding mode in accordance with the rules. Having gained experience, you will switch the transmission on your car in automatic mode, which will allow you NOT to waste energy in vain and maintain the permissible load.

Practice

If the device is unpacked and assembled, the method for adjusting the brakes has been completed, the algorithm on 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 rolled intersection. Interacts with the rear block 3,4,5.
  • Small star. It is used when skiing on slopes, rough rough terrain, wetlands, viscous mud, sand, dense grass. Spins optimally with rear sprockets from first to third.

Why Bike Speed

Whether such technical moments are needed is up to the owner himself. If the bike is used exclusively for recreational purposes, for rare and close trips, it is better to use conventional models, but when the owner of a two-wheeled car plans frequent and long trips to the track, it is worth considering purchasing a product with such equipment. Switching is provided to maintain certain load modes and in the terminology of cyclists, to denote this phenomenon, the word cadence appeared.

It is customary to call cadence the frequency of pedaling that occurs over an equal period of time. It can be conditionally divided into three groups: low, high and optimal.

  • Low. the load on the athlete’s legs is increased, because K. You have to press the pedals very hard to spin the wheel at a low frequency, and this riding style can also be used when going downhill;
  • High. the rotation is very fast, but the efficiency is low. for a certain period of time a very small distance is covered, this option can be useful for burning excess fat accumulations;
  • Optimal. a reasonable ratio of load, frequency of movement and energy consumption to obtain the most beneficial result.

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

Competently switching is to choose a suitable pace at which the cyclist will use 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 helps maintain plant life of components.

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

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 the Shifter. 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 shifter, there are printed 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).

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

How to train more effectively on a bike

Let’s move on to how to ride in order to burn fat to the maximum. It is believed that in the first 40-50 minutes of training, the body uses only glycogen dissolved in the blood (a source of energy derived from glucose), that is, the calories that you ate during the day, and only after that it gets into the bins.

For the most effective fat burning, the load should be in the range of 110-130 beats / min, if less, then the matter may NOT reach fat, and if more, then the body simply will not have enough “octane” of fat, so it will switch to glycogen in the liver.

What to remember

Muscle mass. Within a week of inactivity, muscle strength is halved. The property of muscle mass to lose its volume NOT Having regular physical activity leads to sad consequences. Over time, this effect, laid down by nature in human biology, only gets worse.

By the way, we recommend:

The cardiovascular system. Lack of physical activity and a sedentary lifestyle are directly associated with diseases of the heart and blood vessels. The World Health Organization recommends thirty minute bike rides 4 to 5 times a week. Is it not about high sports results, but about ordinary bike rides in parks?

Cycling and impotence. If you spend several hours a day cycling, you may be one of those who have problems with perineal pain caused by contact with the bike saddle. The fear of the possibility of having problems sexually (especially among men) has existed for a long time, but if you choose the right saddle and size, then problems can be completely avoided.

Cycling with a pacemaker. Riding a bicycle with a pacemaker requires adherence to certain rules in order to avoid interruptions in its operation. You should avoid especially powerful sources of electromagnetic radiation, which come across on the path of the cyclist and adjust the route of your ride.

How are calories burned when cycling?

When cycling, the heart rate increases, which provokes an increase in metabolism and energy expenditure. The cells are saturated with oxygen, which oxidizes lipids. Fats break down with the simultaneous release of energy, which is spent on driving. When a gram of lipids are broken down, about 9 kcal is burned.

So, how many calories cycling burns will be determined by the following factors:

  • Pulse. The higher the heart rate, the more energy is expended.
  • Depth and breathing rate. If you breathe deeply and often, then the muscles are better saturated with oxygen, and fats are broken down faster.
  • Individual characteristics of the cyclist.

Burning calories on a bike also depends on the athlete’s weight, height, age, and fitness level. The duration of the ride and its intensity. Cyclist weight. Anyone who is overweight uses up energy faster while driving.

Determining the Calorie Consumption When Cycling

There are several ways to determine the number of calories burned while cycling, but consider the simplest.

There is a fairly simple way. If we assume that the average body weight of a cyclist is within 70 kg, then it is considered that during the time the calorie consumption is:

  • Light bike rides on city or road bikes. 280 kcal / hour;
  • Mountain bike rides with medium difficulty terrain. 420 kcal / hour;
  • Cycling with elements of sports training and medium loads. 560 kcal / hour;
  • Professional Road Cycling. 700 kcal / hour;
  • Professional mountain bike racing on rough terrain. 840. 1120 kcal / hour.

If you have a different weight, the composition is proportional and Let’s display your numbers in the calorie consumption on a bicycle.

Bicycle Calories

Cycling requires quite decent physical activity and energy expenditure. Cycling calorie consumption varies by individual. Naturally, every person wants to know how much energy he has spent in a certain period of time or the distance covered on a bicycle.

Especially if he ate he set a goal to spend more calories than he gained in the process of eating or saved while lying on the couch. The amount of energy spent while cycling is influenced by many factors:

  • Average travel speed.
  • Duration of trip.
  • Terrain.
  • Height above sea level.
  • Cyclist body weight.
  • Bike type.
  • Type of bicycle tires.
  • Bicycle pressures.

And here are many other minor factors, but which together can affect the result.

How to Calculate Calorie Consumption When Cycling

Fitness calculators in apps tell you how many calories you can burn in a time:

  • Cycling at 15 km / h: 300-400 kk
  • Cycling at 20 km / h: 400-500 kk
  • Jogging 8 km / h: 450 kk

Unfortunately, all fitness trackers shamelessly overestimate energy consumption, for example, the same Endomondo gives 400-500 kk for riding at a speed of 20 km / h. Trackers at least add basic calorie consumption. that is, a person of 90 kg, an office worker, should consume about 2000 kk, so as not to lose weight and NOT get fat, that is, 80-100 kk is burned every hour directly to maintain body work.

These 100 kk are added to the 200-300 calories actually spent, which is most likely wrong, since when we count calories daily, we calculate the base rate separately.

It is better to independently assess the level of energy expenditure using a heart rate monitor, based on personal experience. Nobody but you can know your body better. Recommend slightly underestimates calorie consumption.

Let’s repeat the main

When cycling, the heart rate increases, which provokes an increase in metabolism and energy expenditure. The cells are saturated with oxygen, which oxidizes lipids. Fats break down while releasing energy, which is spent on driving.

So, how many calories cycling burns will be determined by the following factors:

  • Average travel speed.
  • Duration of trip.
  • Terrain.
  • Height above sea level.
  • Cyclist body weight.
  • Bike type.
  • Type of bicycle tires.
  • Bicycle pressures.

If we assume that the average body weight of a cyclist is within 70 kg, then it is considered that during the time the calorie consumption is:

  • Light bike rides on city or road bikes. 280 kcal / hour;
  • Mountain bike rides with medium difficulty terrain. 420 kcal / hour;
  • Cycling with elements of sports training and medium loads. 560 kcal / hour.

I would like to say that nothing is more conducive to weight loss with the use of a bicycle than multi-day group cycling trips with a movement mode of 60. 90 km per day. There is mutual assistance, common goals and interests. Join the cyclists and be healthy!

How many bike speeds do you need and how to switch them?

A common but diminishing misconception is that the more speeds the better.

Need to ask the question which is better? Or who is better?

Today you can find solutions from 1 to 33 speeds. In a variety of combinations: 1×7, 1×11, 2×9, 3×10 (the first number. The number of stars in front, the second number is the number of stars on the back of the cassette). Multiplying these numbers, you get the maximum number of speeds that can be “turn on” while riding.

What does “switch gear” mean??

Gear shifting is a chain transfer from one chainring to another. This changes the gear ratio and force. “on pedals”.

How To Determine The Number Of Speeds On A Bike

Why Bike Speed?

Primarily for convenience. Gears allow you to save power and choose a comfortable pedaling mode Based on:

  • Road relief (plane, ascent or descent, acceleration or smooth braking)
  • The quality of the road surface (highway, Country road, mountains);
  • Required speed;
  • Weather (tail or head wind)
  • Rider’s physical condition.

With the right gears:

  • Move faster and more economically (in terms of physical strength);
  • Get longer service life of bike components;
  • Reduce stress on knee joints.

And also faster to go downhill, climb uphills spent less effort or go at a comfortable constant speed.

How many high-speed transmissions are there?

Rear on the cassette, if the bike is multi-speed, usually from 5-11 stars. So transmissions are 7/8/9/10/11 high-speed.

If the bike has 6-7 speeds, it means that it has one front sprocket (s) and a rear cassette of 6-7 stars. If 18 or more, there are 3 chainrings and a rear cassette of 6-7 stars. Sometimes the rear cassettes are 9-10-11 stars, which allows you to bring the number of speeds to 27-30.

The front usually has 1 to 3 stars.

Why did everyone want to make faster speeds before?

It was believed, not unreasonably, that the greater the gear ratio on a particular bike, the more accurate the gear can be selected for a specific terrain. It really is.

However, today it has come to the conclusion that fewer sprockets on a bicycle can be dispensed with. The most important to save weight, since the extra stars in the front and front derailleur are removed.

Why does the chain NOT fall off one sprocket in front?

Development of recent years. A special Narrow Wide chainring with variable and higher cross-section of teeth, as well as a special rear derailleur, which dampens all unevenness. Taken together, this eliminates the need for a chain damper on the chainring.

How much does it all cost?

The trend is that the higher the class is the transmission. From 7 to 11 speed, the more expensive it is.

  • 7-9 speed bikes are put on the most affordable bicycles;
  • 10 speed bikes can be found on middle class bicycles;
  • 11 and even 12 speed versions are found on professional models.

The more stars there are in the cassette, the closer they become to each other and the chain will be thinner. From this, the price of such a product will be higher, and the durability is lower.

In the photo 10 and 11 high-speed cassette.

What do the numbers mean in the description of the transmission 48x36x26T?

They represent the number of teeth on the sprocket. If you are a beginner, then the information is almost useless for you as there is nothing to compare with. But if you are already an experienced bike enthusiast, you can choose a new transmission or bike according to your preferences based on the experience of previous bicycles.

How to properly switch gears on a bike

If you want your chain and sprockets to last as long as possible, it is recommended to switch at the moment of minimum load. Let us explain. Shifting in the middle of a climb puts a very heavy load on the transmission, which can lead to situations up to a derailleur break or an open circuit.

Also try to switch early and avoid excessive chain skew.

Gear shift breakdowns.

After some riding time, whether you lubricate the chain or not, attention to the drivetrain may be required. The chain may stop switching perfectly as at the very beginning. Problems can be as follows:

  • The gearshift cable is stretched. It is required to pull up with a special lever on the shifter or switch;
  • Too much dirt has accumulated in the cable jacket. Better to replace together with the cable;
  • Rear derailleur NOT configured. Customization required, better in a workshop.

What types of steering wheel switches are?

Shifting gears with special handles on the steering wheel. shifters. They are:

  • Rotary. gears are switched by turning the knob;
  • (Revoshift and grip-shift, grip-shift). when you rotate the handle towards yourself or away from you, the speed changes.

    Lever. gears are switched by special levers.

Dedicated finger levers. One switches to a higher speed, the other to a lower one. These shifters are more comfortable for many cyclists, less whimsical to maintain, but often more expensive.

Typically, the left shifter is responsible for shifting the three front gears, and the right shifting gears in the rear cassette. Thus, the left derailleur and chainrings are used to adapt to the main terrain. And the right one for private and short-term changes during the trip.

What “cadence”?

More professionally speaking, changing speeds changes the cadence. Cadence is the cadence and the required pressure applied to the pedals by changing the gear ratio between the wheel and the pedals. Cadence is important in terms of strength and health benefits to evenly distribute the energy expended on pedaling.

The optimal cadence is considered to be in the region of 60-100 rotations per minute.

If you are driving uphill or on uneven terrain, you need to make a lot of effort to pedal, which, for a long time, can lead to arthritis. Turned on low speed, you will relieve yourself of pedaling, Reduce the load on muscles and joints, but the bike will go slower.

On a flat track or when descending a mountain, you need to turn on High Speed, then more effort is required to pedal (in comparison with models without speeds or other gear), but the two-wheeled horse will become faster, more stable, it will move smoother and more stable.

So how many speeds do you need to be happy?

Let’s answer this question as follows. As in the article how much does a good bike cost, we will note that it all depends on the use of the bike and the place of riding.

If you only ride on paths in a park or sidewalk, you really don’t need to cycle speed. But fans of cross-country driving, long journeys with alternating ascents, slopes and flat sections, real athletes will appreciate this parameter.

For city and folding bicycles, there is a need for more than 7-9 speeds. For them the thesis “the bigger, the better” does not work.

For mountain bikes of the middle and high level, 1×10, 1×11 solutions (one sprocket at the front and 10-11 at the rear) are already offered today. Wherein “Total” 10-11 speeds are enough even for mountainous terrain. On more affordable bikes, options like 2×10, 3×9 are more common.

For amateur riding, 18 speeds are enough. Riding in a city, park or woodland less demanding on gear ratios.

How to switch

There have never been and never will be strict rules for gear shifting. But there are some combinations that help to shift more efficiently, as well as prolong the life of the entire transmission. Indeed, during operation, the chain is often skewed due to the arrangement of the sprockets in parallel planes, which causes its wear.

The picture shows the recommended gear combinations for different types of terrain.

In order to reduce wear and increase the life of the gearshift mechanism, sprockets and chain, it is recommended to shift at the moment of minimum load. This means that shifting in the middle of an uphill place a very heavy load on the transmission, which could result in derailleur breakage and chain breakage.

Therefore, riders and amateurs participating in cross-country competitions, where the load on all the mechanics is especially great, try to protect themselves from unpleasant surprises and acquire high-class attachments, as well as monitor the condition of the chain and stars, regularly wash, adjust or replace mechanisms.

The need to switch

The gears on the bike are primarily needed for comfortable, efficient movement in certain conditions. With their help, the cyclist can go faster, accelerate downhill, effortlessly drive up steep inclines, and easily maneuver in difficult areas. for example, in sand or soft mud. or around the city, making constant Detours. The presence of speeds is one of the hallmarks of a mountain bike, and the more there are, the less suffering will be caused by difficult paths and paths.

How many speeds on the bike

People who are far from cycling still have no idea that modern bicycles are equipped with many speeds, a kind of “gearbox”. The presence of a gearshift mechanism makes it possible for a cyclist to ride in different conditions, which are determined by both the road surface and the terrain. And yet, how many speeds on a bike does a rider or amateur need to have to be completely happy? For everyone, happiness is measured in its own way, but we will try to find out what the programs are for.

How many speeds on the bike. depending on what!

So, a modern bicycle has 2-3 stars in the front (system) and 5-10 stars in the back (cassette). Gear shifting is carried out using the rear and front derailleurs, which work with the chain, throwing it over the stars of the connecting rod system and along the small stars on the rear wheel hub, from which the speed changes. Gear shift control levers (coins) can be in the form of levers and grip shift. a rotary shift mechanism on the handlebar.

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 the front, and 8 stars in the back, for a total of 24 speeds. There are other variations: 3×5, 3×6, 3×7, 3×8, 3×9, 3×10. Moreover, systems and cassettes can have a different number of teeth on the stars, the speed also depends on this.

Feel the bike. switch correctly

You can only set the right combinations individually by putting your bike to the test. Everyone has different physical capabilities, and for someone 5 stars are enough, and for someone 10 is not enough, because the main trump card, whatever one may say, remains constant training, exercises and loads on the working leg muscles.

The switching picture shown is a rough guideline that a beginner can use. Experienced cyclists who have learned to feel their bike, and not watch whether the gear is correct. The driving conditions and the level of training of the person sitting behind the wheel of a two-wheeled vehicle are the determining factors.
