Which Sprocket Corresponds To Which Speed On The Bike

How to switch speeds on a bike: rules and basic mistakes

All truly modern bicycles are equipped with a large number of speeds, which greatly simplify the riding process. Different gear ratios allow you to change the speed depending on the terrain, road congestion or the banal fatigue of the rider. But for all this to be of practical use, you need to understand how to switch speeds on a bicycle, and do it correctly.

Planetary systems

In addition to the familiar external switches (in the form of a dangling foot on the rear wheel), there is another fairly common type of gearbox. planetary hubs. The mechanism of operation is such that a gear system with a set of different gear ratios is located in the rear hub housing. This design is very well protected from dirt and moisture, which allows it to work for many years even without special maintenance.

The Shimano Inter 3 and most Sram hubs use a clickbox as a derailleur. If you take a closer look, on the right side of the frame, on the rear wheel axle, you can see a cable line or a plastic box on Nut. this is the clickbox. It controls the gears inside, and itself is controlled by the shifter. The gear selector on the handlebars on a planetary bike does not visually differ from a grip shift, but it has a set of second indices and therefore is NOT compatible with conventional transmissions.

On some bushings, for example, Sasch S7 and in general all versions of those bushings, to switch it was necessary to act like this:

  • During acceleration / deceleration, stop pedaling.
  • Switch speed on the shifter.
  • Start pedaling in a new gear.

If I could not quit the rotation, then the gear will not change. Shimano Inter and Sturmey Archer have this feature.

What speeds to use?

Many novice riders are also interested in which bike speeds should be used more often and which should not be touched at all. Unfortunately, this question cannot be answered with certainty, since all transmissions and people are different. Someone likes fast and aggressive driving, someone more measured, away from mud and extreme, and accordingly, the sets of speeds used will be completely different.

One thing is for sure: in 80% of cases, ordinary users practically DO NOT use the left shifter, but simply put the second gear and eat until the star is erased. Indeed, set 2 / (where is any cassette gear) is very popular as it contains most of the most commonly used gear ratios, but it is worth using other speeds to extend the life of the transmission.

Cycling gear changes correctly

If you constantly follow at least some of the rules for shifting speeds on a bicycle, you can significantly extend the life of the transmission. Many, without hesitation, pull the levers on the shifter. Doing this is strongly discouraged, since every component of the drive suffers greatly.

Here are some tips for using all the speeds on your bike correctly and safely:

  • Switch gears to bike off load. To do this, you just have to accelerate harder, regardless of the selected gear and at the peak moment click the shifter.
  • If you stopped, at the beginning of the movement you found that the gear is set too high and starting from it is impossible, it is better to switch it “on the fly” by lifting the rear wheel and turning the pedals, slow down.
  • Avoid tightly skewing the chain, say 3/2 or 1/9 sets. This will grind off the stars severely and may cause the derailleur to bend.
  • DO NOT jerk the levers with all your might, unless you have expensive triggers. On old shifters, although there is automation, it still has no limiters, so there may be problems with the rear derailleur on the bike.
  • Avoid Blocking the Transmission with Branches and Grass.
  • If the chain suddenly starts to slip even on level road sections. Contact a workshop to measure its wear.

In general, if the speed and terrain allow, try to think one step ahead, when to stick the speed higher, and after how much slow down.

How the switching system works

There are two types of cable on a bicycle: for shifting and for braking. Here is the quality of the first one directly depends on the speed and clarity of the caliper. And the brake cable may not be at all, since in older bike models it is reasonably replaced by a hydraulic line.

Among all manufacturers, Shimano derailleurs are among the most famous and accomplished parts. Only Sram can compete with them. The Japanese pay enough attention to both the Beginner Groups and the professional equipment kits, which go well with the cool racing frames.

What not to do

For good shifting on low to mid-range transmissions, it is recommended NOT to do the following:

  • Switch speeds under load.
  • Switch several speeds at a time.
  • Starting AT NOT fully shifted gear.
  • If the chain is tightened under the carriage or bushing, do not try to pull it out, put more pressure on the pedals.

Now let’s finally figure out how to switch speeds on a bike in different situations. Beyond that, learn some of the features and secrets of shifter control and transmission care tips.

Road bicycles. Mountain bikes

The truly versatile bikes are cross-country fables. It is convenient to ride them around the city, and they are NOT afraid of paving stones, and you can dash off outside the city for pleasure. On UK bicycles, in contrast to city bicycles, slightly more gears are installed. On a budget cross-country bike, there are at least 21 gears (3 in front and 7 in the rear), and on advanced models about 30 In everyday life, only the cassette characteristic is often used to indicate the number of speeds. So, a bike with a 3/10 set can be called a 10 speed bike.

The hardtail has a fairly large number of different gear ratios for a comfortable ride both in the city and on rough terrain, and due to the absence of shock absorbers in the back, almost all the pedaling energy is directed to accelerate the bike.

On the UK fables, either trigger shifters or grips are installed (on very cheap models, usually Chinese or children’s). The former are much more comfortable and hardy, while covering a larger range of gears (7-12), in contrast to grips (8 maximum).

Road bikes

The city also includes a full-fledged Road bike. light, mobile, with wheels 700×19-35s and a very high gear ratio, they are designed to ride on prepared surfaces and are capable of developing a fairly high speed.

A true road bike will switch gears like trigger bikes, not release. The fact is that sports road bikes are equipped NOT with ordinary shifters, but with monoblocks, often referred to as pistols. Here, switching takes place with the help of the brake lever, which, in addition to direct pressure, can also deflect to the inner side of the steering wheel. Thus, the transmission on the cassette is lowered. It can be raised with a separate lever under the thumb.

Cycling Gear Shifting. WHEN YOU NEED?

Let’s figure out how to correctly and when it is necessary to perform gear shifting on a bicycle, i.e. Let’s find out the principle of gear shifting.

Most bicycles have two or three drive stars in their design, which are located in the front, and seven to ten driven stars, which are in the back.

The front stars are numbered from small to large, and the rear stars are numbered from large to small. Consider how the gear changes on a bicycle, three stars in the front and eight stars in the back:

  • The large chainring is used if you are driving on a flat, good road and you are NOT going to meet a duo with strong winds. This star assumes the use of led stars numbered 4-8.
  • The middle sprocket is designed for driving on dirt roads, sand and uneven asphalt. The driven stars that are used with her are numbers 2-6. This star will let you ride if the headwind is strong enough.
  • The small chainring is designed for uphill climbing, and also when driving in mud, sand, swampy soil, thick grass. The rear sprocket numbers that are used with it are 1-5.

Improper use of THESE devices will reduce their service life. For example, if you allow the chain to be heavily skewed.

When choosing gears, you should remember about the concept “cadence”. This word refers to how fast your bike pedals are. The cadence depends on the number of revolutions per minute. For comfortable movement, it should be equal to somewhere between 80-110 rpm.

Therefore, it is worth choosing gears so that the cadence is kept around 80-110 rpm. When starting, you should not immediately take high gears.

It is better to warm up the muscles at light speeds and reach a comfortable cadence, and then you can shift higher gears. As your riding experience improves, you will learn to intuitively sense which gear and when to shift.

MECHANISM for external switching

These derailleurs are used much more frequently on bicycles. Gear shifting takes place using two switches: rear and front. Let’s consider each of them in more detail.

TIPS AND RECOMMENDATIONS

  • The bike speed switches only while driving.
  • If you are changing gears, before that you should lower the pressure of your feet on the bicycle pedals.
  • If you have a slide on your route, it is better to switch the speed before going up.
  • Switching speeds should be done gradually, do not jump over several speeds.
  • And most importantly, make sure that a large skew of the chain is not allowed, as this will significantly reduce its service life.

By following these simple rules, you can increase your level of riding, as well as cycling does NOT turn into torment for you.

Bike speed switch: how to set up and switch it CORRECT

Bicycle gearshift is a transmission component that directly serves to shift gears. Correct speed regulation is an important part of a comprehensive approach to comfortable and safe cycling. Next, let’s talk about why you need a speed switch on a bicycle, what types there are, how to set up and how to switch speeds correctly on a bicycle.

  • Cycling speed shifting. when needed?

How to set up gear shifting on a bike

Over time, every cyclist has trouble shifting gears. Either you cannot switch from one gear to another. by jumping over a couple of stars, or it is not possible to switch at all. This is where the need for awareness of how to set up gear shifting on a bike comes in.

Setting the speeds on a bike is not a complicated procedure (although at first glance it seems like that). If you are setting up two switches, start from the rear.

How to set up the REAR SWITCH

To begin with, you must make sure that it is not bent (the chain tensioner is parallel to the cassette stars). Now let’s start adjusting.

At high speed, the chain should be on the small star of the cassette. We put everything in this position. To adjust, we need to find two screws (in the figure they are designated H and L).

Screw H is necessary. Tighten so that the switch roller is aligned with the small star. Likewise, tighten the L screw. the roller should align with the large sprocket.

After that, we pull the cable (the maximum speed is on the shifter). It should fit exactly into the groove near the fixing bolt (number one in the picture). Now it should be tightened.

Fastening the cable with a stretch. Check if high gears engage well. If not, loosen the cable with the adjuster (marked with number two). Also check if the speeds are reset well (if it is bad, then pull the cable while unscrewing the tension adjuster).

The last item in the rear derailleur adjustment will be to set the smoothness when shifting gears. To do this, you need to put the chain on a small star in the front and a large one in the back.

The tension screw (marked with number three) should be tightened so that on the rear derailleur the upper roller is as close as possible to the star, but does not touch it.

Now put the chain the other way around (in front on a large sprocket, and at the back on a small one). the roller should also NOT touch the cassette sprocket.

INTERNAL SHIFT MECHANISM

These types of switches use planetary bushings. In this case, the shifting mechanism is hidden inside the rear hub, which results in one sprocket on the front wheel, a chain, and one sprocket on the rear wheel.

The current planetary hubs have a different number of gears (from three to fourteen), they can also have a built-in brake.

Such mechanisms are mainly used on walking and road bicycles, very rarely on mountain bikes.

Consider the merits of these switches:

  • Increased resistance to weather and road conditions (parts of the mechanism are in the case)
  • Built-in brake;
  • They are quite reliable and durable;
  • Such a mechanism allows you to change gears rather than pedaling;
  • Simple enough maintenance.

However, such mechanisms also have disadvantages:

  • Heavy enough weight;
  • Complication of movement may occur due to strong friction of the nodes;
  • It is impossible to repair the mechanism in field conditions.

HOW TO PROPERLY switch SPEEDS on a bike: A FEW practical tips

Every cyclist should know how to properly switch speeds on a bike. Correct gear shifting will allow you to drive much faster and more comfortably with less effort, and, moreover, this will increase the life of the sprockets and chain.

The first thing I would like to note is that I always select the gear so that it is easy to pedal (cadence 80-110 rpm).

So, what you need to know for proper gear shifting?

Modern bicycles have a chain drive. This means that when the cyclist pedals, he transfers the force from the pedals to the cranks, and then to the stars of the system, which are located on the front wheel (leading), and then, accordingly, to the driven cassette stars. Ending the effort to spin the wheel.

If we consider switching speeds, then the essence is to drag the chain from one star to another. Of course, while choosing the right star size.

Let’s take an example of the correct speed switching algorithm. We put the middle sprocket in the front and start off. I select the gear with the rear derailleur, taking into account that there is no heavy load on the legs.

If the road goes uphill, then I throw the chain over the big star in front. We carry out this principle of action with low gears, when we are going uphill, and there is not enough range of cassettes, with the middle front chainring on, then we go to small.

Most importantly, remember that the middle chainring is the working chainring, only there will be no significant chain skew from it. If you take into account all of the Above when riding a bike, then the transmission will last for a very long time.

COMBINED GEAR SHIFT MECHANISM

Such gears are hybrids of the conventional gearshift mechanism and the planetary hub.

Such mechanisms are in most cases installed on city bicycles. On the second types of bicycles, they did not receive their distribution, since they have all the shortcomings, which have mechanisms for internal and external switching.

Action guide: how to set bike speeds with front and rear dealers

The gearshift module, capable of providing a comfortable gear ratio in all riding conditions, is the most vulnerable system on a bicycle. Smooth and fast operation of the rear and front derailleurs, depending on the operating conditions, is observed only for several tens to hundreds of kilometers, after which a qualified adjustment of the nodes is required.
How this article will be useful to the reader and what we will find in it:

Step # 2: how to tune the front speed row on a bike with two or three sprockets

Setting up the front derailer occurs only after debugging the rear derailleur. Before starting the process, you should definitely check two parameters here:

  • Parallelism of the inner chain frame;
  • The gap between the Largest sprocket and the outer frame of the dealer (should be about 2 mm).

The procedure responsible for the task of how to adjust the forward speeds on a bicycle includes three key transitions.

Step 1: 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 fixing the cable;
  • Drum for cable tension;
  • Limiting screw for lowest gear (Low)
  • Limiting screw for the highest gear (High)
  • Chain adjuster screw.

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

Quality control by transfer

It is a key operation in the process of how to set the rear speed range for both road and mountain bikes. The process technology is simple: the smallest sprockets are installed in the front and rear; by rotating the adjusting drum, they ensure that the re-throw works clearly and instantly:

  • In case of insufficient tension of the cable, the switch poorly (slowly) switches to lower gears (large sprockets). the drum must be returned counterclockwise;
  • In case of excessive tension, the derailer stays in the same position (it does not go well into the upper gears. small asterisks), emitting a knock (metallic clang) during operation (the drum must be turned clockwise).

Setting the quality by flip

The answer to the question of how to adjust the smoothness of gear shifting on a bicycle is quite simple. By rotating the adjusting drum, a dead zone is found, in which the movement of the dereiler, both from upper to lower gears, and vice versa, will occur instantly and without delay. By twisting the drum, the switch will move more efficiently from small to large stars. When spinning the drum, a completely opposite dynamics is observed.

Preparation for commissioning

Before adjusting the bike speeds, you need to clean and lubricate the chain and derailleurs. It is also advisable to produce:

  • Inspection of the drive cable for the presence of rough bends that violate the smoothness of its movement along the inner surface of the shirt, unweaving and solidity of the connection with a stop based in the shifter;
  • Monitoring the condition of the jackets. in case of strong wear of the inner, often silicone insert, or the presence of fatigue fractures, their replacement is required;
  • Inspection of the rear derailleur and the frame counterpart (rooster) for deviations from the vertical position. the cassette rollers and the counter sprocket must lie strictly in the same plane.

Also, before adjusting the speeds on the bike, it is necessary to loosen the cable tension and it is strongly recommended to turn the adjusting drums all the way. In the already tuned state, the following dependence is observed: the less the drum is unscrewed, the more accurately the system works, and also a guaranteed departure margin is maintained, which is necessary for instant compensation of the cable lengthening during the trip.

Operation of the transmission: how to correctly switch speeds on a bicycle in various conditions

Maintaining cruising cadence when driving on flat, flat areas or pedaling confidently and lightly on rough terrain. the transmission unit of a modern bicycle is able to maintain the most suitable gear ratio for an athlete.

Experts give the following recommendations on how to properly switch speeds on a bicycle:

  • Change gear only while driving;
  • Moves to the required sprocket only under conditions when the minimum load acts on the chain (it is desirable to reproduce this process at a high cadence)
  • DO NOT change gear when climbing / descending (suitable stars must be selected in advance)
  • On muddy, sandy and slippery areas, drive in higher gears (deliberately increase torque to avoid loss of traction).

With the correct implementation of the sequence of actions in the process of how to adjust the gear shifting on a bicycle, the following requirement should be attributed to the main limitations of the gear selection process. to exclude the skew of the chain, which significantly reduces its service life. You can avoid the latter, using the example of a 24-speed system, as follows:

  • A small sprocket (1) is installed in the front, in the back: 1. 4;
  • Front. middle (2), back: 4. 6 (7)
  • Front. large (3), back: 6. 8.

High gear limiter adjustment (H)

It is done as follows:

  • The chain is installed on the largest sprocket in the front and the smallest in the back;
  • By turning screw H, you should find the optimal position in which the chain will be as close as possible to the outer frame of the switch, and not touching it.

Tensioner adjustment (guide roller height or chain angle)

In the technology “how to adjust the rear speed on a bicycle”, this adjustment is aimed, all other things being equal, to improve the quality of gear shifting.

The smallest sprocket is installed at the front, the largest at the back. By turning the screw, the idler roller approaches or moves away from the sprocket. The task is to achieve a gap between the roller and the sprocket of 3-5 mm.
