How to shift gears on a bike

shift, gears, speed, bike

Almost all modern bicycles are equipped with a large number of speeds. There is an opinion: the wider the speed range of the bike, the better it is.

All this, of course, is true, but for those who first got on a high-speed bike and do not know how to properly change gears on a bicycle, this function is useless.

To appreciate all the advantages of this function at its true worth, you need to understand what it is all about and learn the basic rules.

The number of gears determines the number of sprockets on the front and rear wheels. Determining the number of speeds on your bike is easy.

You need to count the number of stars on the front wheel (usually there are from one to three), and then count them on the rear (as a rule, there are more of them than on the front). Multiply the counted numbers among themselves.

The resulting number is the number of speeds included in the bike.


The third transmission is suitable for driving on quality asphalt, which allows for high speeds. Back. not less than fourth.

For beginners, mastering the basics of moving from one speed to another seems difficult. However, constant training will eventually bring it all to automatism and will allow you to fully enjoy all the benefits of this function.

Gear shifting rules

There are a number of specific rules for shifting gears. Compliance with them is mandatory!

The second

For driving on poor terrain, poor quality road surface or dirt road, it is recommended to use the middle front transmission. The back one should be in the range from 2 to 6 (or 8, if the bike’s capabilities allow).

How to properly switch speeds on a bike. gear selection, shift rules, errors and problems

A bicycle is a rather complex and at the same time unique design. How to properly switch gears on a bike? The art of cycling requires attention and patience, because it is not enough just to buy a bike and learn how to balance well.

An important feature is the speed control. At first glance, this algorithm is not difficult, but in fact it has some nuances.

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 the 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 the sake of interest. If it is around 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 to 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 flip 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

    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 for this you will need to accelerate. 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 on the front and 7 stars on 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 one moves the rear chain spreader.

    On the shifters, there are numbers showing the number of the current star. The stars 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 selection 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 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 well-groomed 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, thick grass. Spins optimally with rear sprockets 1 to 3.

    We consolidate knowledge or how to change gears correctly on any mountain bike without harm to humans 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 while moving. 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 transmission exclusively with the rapid 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 to several stars at once. It only takes one click to change the position of 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 the front and a large sprocket 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, is to use the rear sprockets in the whole, and put only a large one in front.

    For your information. 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 transmission speed 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 purpose 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 moving 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 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 to 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 begins to turn into red, then we switch to a higher gear. For convenience, you can also use a speedometer. In this case:

    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! Only in this way will you be able to move around on a bike as efficiently as possible, 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.

    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 when driving 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 traffic (bumpers, pillars 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 of braking to a complete stop.

    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 of the SAE30 / 85-90W class.

    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 the second to the 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.
