How To Properly Pump A Bicycle Wheel

How to inflate a bicycle wheel? How to pump up a bicycle wheel?

Pumping the wheels with air is no big deal. But not knowing all the subtleties, you can spoil such a simple process.

How to properly inflate a bicycle wheel?

To properly inflate a bicycle wheel is possible only while observing the manufacturer’s recommended air pressure. The sides of the bike tires contain all the information necessary for the correct operation of the bike. The manufacturer indicates two values: the minimum pressure and the maximum allowable.

When pumping, consider:

  • The rider’s weight is taken into account. Manufacturers do not indicate the minimum weight in the characteristics, but the maximum is always. And although there is a certain paradox between the characteristics of bikes and tires in terms of weight limitation. however, most bikes are designed for a maximum of 120 kg, and one good tire can withstand more than 100 kg, for a total of more than 200 kg for the entire bike. And this is not without reason. when falling into a hole, or when jumping, upon impact, all the weight goes first to the front, and then to the rear wheel, therefore, it turns out that your weight is the impact force = a load of more than 100 kg per wheel.
  • The right pump. To properly inflate the wheels of a bicycle. a bicycle pump must be equipped with a pressure gauge. If, unknowingly, you purchased a pump without a pressure gauge, then the situation will be corrected by a special pressure gauge to check the tire pressure. Most of the models of such pressure gauges are adapted for an automobile nipple. If you have a Presta nipple, you only need a bicycle pump with a pressure gauge. Because even the tire changers do not measure the correct pressure on the Presta nipples.
  • The purpose of the tire. A purchased bicycle tire that is designed to ride on dirt and dry ground at any pressure will not perform well on asphalt. Do not use tires designed for hard road surfaces on the ground for a long time. The pressure in highly specialized tires must be selected by trial and error. we pump the average pressure between the minimum and maximum recommended. Trying to ride. If the feeling is that it is harsh, we lower it a little with a pressure gauge, if it is very soft, then we pump it up. It is imperative to find the optimal pressure in the wheels of the bicycle for your weight. Remember this meaning.
  • Temperature difference. If in the heat you, for example, pumped 4-5 atmospheres, and in the morning there is only 3.8bar left. do not rush to disassemble the wheel and look for a puncture. It is hot during the day. the air heats up and the tire pressure rises. It’s cool at night. the pressure drops. Therefore, it is recommended to inflate the bicycle wheels in the morning. If it is hot during the day, cool at night. you can pump 0.2 atmospheres less than your usual pressure in the bicycle tires of two-wheeled vehicles in the morning for a more comfortable ride, but it’s better not to do this. the rims will be more intact.
  • Inflating your bicycle tires with gas is the best option to protect you from temperature extremes. CO2 gas is not affected by temperature changes. Initial pressure does not change while riding. For such a procedure, special bicycle pumps are provided for inflating the bicycle wheels with gas.

What is definitely not recommended is to check the tire pressure with your finger. By pressing your finger on the bike tire, you cannot determine the pressure in any way. Improper tire pressure ALWAYS leads to increased tire wear. Over-inflated bike tires. wear quickly in the center. Underdeveloped. increased wear along the edges. Only the correct pressure will ensure full contact of the entire tread with the road surface. This will not only extend service life, but also give better handling and traction.

These are the simplest tips that help and rescue millions of cyclists. I hope our article was useful for you too.

How to pump up a bicycle wheel. methods, instructions

You can’t go far on flat tires. In order not to turn into a dull pedestrian in an instant, you need to know how to pump a bicycle wheel with a hand pump. It may seem to someone that there is nothing tricky here, but you still need to know some of the nuances, and today we will talk about them.

Required tool

A hand pump is needed to inflate the wheel. There are two types of instrument:

  • Standard.
  • With pressure gauge.

Equipped with a gauge, the pump is a more practical solution because it allows you to monitor the pressure level in the bicycle chamber and prevent exceeding the recommended parameters.

How to properly pump wheels with a hand pump

  • Remove the nipple cap.
  • Bleed air while holding the spool.
  • Insert the outlet and turn the valve to the maximum limit.
  • Take the stem and begin translational movements, thereby filling the chamber with air.

What should be the pressure

The recommended value is stated in the data sheet. It is clear that documents may not always be at hand, so the required parameter can be found on the bus. Average indicators:

  • on asphalt. from 2 to 3.5 atm.
  • cross country. from 2.5 to 2.8 atm.

You can determine conditionally by probing the camera around the perimeter. If the deflections are not felt, then everything is in order. However, more experienced cyclists and craftsmen recommend using a pressure gauge for this purpose. a device that comes with most modern bicycle pumps. I must say that an insufficient amount of air in the chamber is fraught with not the most pleasant consequences:

  • poor maneuverability;
  • high probability of puncture;
  • have to pedal with great effort.

The situation is approximately the same with the wheels, the pressure level in which exceeds the permissible standards. This is fraught with:

  • insufficient adhesion of the wheel to the road;
  • high probability of an emergency on the road;
  • punctured tires.

The optimal amount of air in the wheels is a prerequisite for comfortable and safe driving.

How to inflate a wheel with a car pump

Many bicycles are equipped with a shrader. This only means that the wheel can be pumped up by means of a compressor, which is available at almost every gas station. Sequencing:

  • Remove the cap and insert the pump connection.
  • When using a universal device, put the jumper in the “auto nipple” position.
  • Close the front cover and turn on the pump.
  • Switch off and disconnect the pump, tighten the nipple tightly.

What if you have to deal with Presta? Here you need a special adapter to which you can connect the compressor. You can also push the jumper out with the thin end. Inflate the wheel according to the recommended rate.

How to inflate a wheel without a pump

It is not always possible to pump up the wheel in the usual way. But the way out can be found in any situation. There are several ways:

  • Vacuum cleaner with blow-off function. A flexible hose is used to connect household appliances to the nipple. For better sealing, you can use electrical tape, tape, pieces of fabric, etc.
  • Regular plastic bottles (2 pcs.). Cut off the lower part from one and, passing a thin hose through the neck, connect it to the outlet of the chamber. You need to insert a second bottle into this structure and pump air.
  • Mouth. Like a balloon.

Well-inflated wheels are the key to a safe and comfortable ride. When creating the right pressure, it is important to consider the type of nipple and the recommended parameters specified by the manufacturer.

How to pump up a wheel with a bicycle pump

Hello! My name is Darina, I am an illustrator and graphic designer, recently I was fond of cycling around the city and now I am writing about my experience in It’s my! Bike. When I was 10 years old, I rode a bicycle in the country house. it was my only and favorite transport to fly through the fields and get to friends, dash away from a scary abandoned house or quickly drive home under an owl ooh in the dark. Probably like many. After that, for 12 years, I almost never used a bicycle (but secretly dreamed of going to the market and in a skirt with a wicker basket and a skirt). in the center I was scared to drive next to cars, and on the sidewalks it was unbearably slow. Everything changed when I fell in love, and my friend, and now my husband, gave me a blue road bike and for the first week accompanied me on all my routes. in the morning to work, in the evening for salsa, on weekends to explore the markets and bike paths, because I was alone it’s so scary to drive next to the humming cars! When I got used to it and felt equal on the road, just like the driver of a car, I realized that there is no better transport, and now I talk about how life changes when you ride a bike (go to the nearest park for lunch from work, overtake a traffic jam. get Pavlova’s posture, improve concentration). Plus, I’m so impressed with Copenhagen, which has more bicycles than pigeons, that I wish it were the same. Every day I choose a bike and tell you why.

When I ride my bike, it rarely happens to me that the wheels are flat and I need to pump them up: every morning I go out with a pump to the yard where my bike lives and check the elasticity of the wheels. I check them ingenuously. I feel the tire around the entire circumference and if it bends somewhere, then you need to tone it up.

Pumping up a wheel with a hand pump is not difficult, and even mischievous. you immediately remember how in the country before you drive off for the whole day you quickly and quickly pump up your bike and fly out of the yard with a bullet.

I spin the wheel so that the nipple (the very process on the wheel) is on the side. Almost all modern pumps have two holes. a larger and a smaller one for two types of nipples, I think you will see which one suits you.

I unscrew the nipple cap, put the pump on it, lower the pump lever down and fill the tire with air (almost morning exercises are obtained, especially if you pump not only with your hands, but with your whole body weight) Now we snap the lever back, remove the pump and tighten the cap on the nipple. Finally you can rush on business.

I try to find a balance in this matter. if I don’t finish it, then it’s hard to drive, and I’m angry that the wheel is almost dragging on the asphalt, I have to put a lot of effort, and the wheel is rubbing. If you are pumping, then the tire may burst from the glass or jumping onto the curb. There is no ideal recipe, as in luck, with inflating the wheels, but on the side of the wheels is written the maximum to which you can pump the tires. Most pumps have a pressure gauge and it is better to choose a pump with it, because there you will see exactly how much more you need to pump up the wheel for an easy ride.

Pumps with a pressure gauge are available on the It’s my! Bike website

How to use a bicycle pump. How to pump up a bicycle wheel with a hand pump

Meanwhile, cyclists feel too little or too much pressure. When the wheel is not inflated to the desired value, more effort has to be applied when driving. the contact area of ​​the tire with the surface increases. If the wheel is pumped too much, this is also not good, as it can lead to a defect in the camera or its explosion.

The tire pressure is checked with a pressure gauge. Usually, the pressure that is recommended for your bike or tires is indicated in the technical data sheet of the two-wheeled vehicle, or directly on the tire itself on the side (more often indicated in bars. bar, or pounds per square inch. PSI).

Pumps

A bicycle pump is a must have for every cyclist. There are several main types:

  • Manual bicycle pump;
  • Floor standing (known as car pumps);
  • Pumps with CO2 cylinders;
  • Fork for shock absorbers or the so-called high pressure pump.

The owners of those bikes, in which the nipple on the tire fits the hoses of car compressors, are most fortunate. But when pumping the wheels in this way or using a compressor at a gas station, you need to constantly monitor the pressure gauge readings and pump with a series of short clicks. the power of car compressors is enough to quickly pump up a bicycle tire.

However, regardless of the type of nipple and the ability to use a car compressor, all cyclists are advised to have at least a hand pump with them on the road. They are small, compact, lightweight (made of plastic, aluminum or carbon), affordable and easy to use. They have mounts for mounting on a frame, can also be carried in a. backpack or bag. On the market you can find a hand pump with a pressure gauge that is compatible with different types of nipple.

How to pump with a hand pump?

  • Choose a location where you can move freely around the bike. Position it in such a way that it has support and you have access to the nipple;
  • Unscrew the cap from the nipple, and completely release the air from the tire;
  • Connect the hose head of the hand pump (if it has a hose) or the head itself to the nipple. Even if your hand pump has a pressure gauge, it is important to calculate how many strokes need to be made to achieve the optimum pressure level. This is necessary in order to, if necessary, inflate a bicycle wheel without a pressure gauge. During the inflation process, check the pressure from time to time. The optimum level for inflation is considered to be 5-6% below the value indicated on the wheel;
  • Screw on the nipple cap. Loose cap can contribute to premature deflation of tires.

To pump a bicycle wheel with a hand pump, you will have to stock up on time and energy. Due to the small air chamber of this type of apparatus, it is necessary to perform 200-300 strokes, depending on the volume of the chamber. In this sense, double-acting hand pumps are effective, which pump air both when the piston moves down and when the piston moves up.

Remember, choosing the right pressure is the key to a pleasant bike ride. After all, the speed, and ride comfort, and the mechanical state of your bike as a whole depend on this. Check your wheels periodically to keep your ride safe.

Bicycle Pump

The long-awaited summer cycling season is in full swing with hundreds of cyclists on the streets. And this spectacle cannot but rejoice, because every year there are more and more cyclists. Today we will talk about such a simple but necessary thing for every cyclist, like a bicycle pump.

A bicycle pump is a must have for every cyclist. After all, you will not go to a gas station or bicycle service every time to pump up a wheel. In addition, a puncture may occur on the road, and if you do not have a pump, then you may be provided with a long walk. Therefore, you must carry a bicycle pump with you, along with assemblies, a bicycle first aid kit, a spare camera and a universal wrench.

There are several types of bicycle pumps. The most common is a conventional hand pump. There are also stationary floor pumps and very compact bicycle pumps with CO2 cylinders. Below is a little more about the different types of bicycle pumps.

Bicycle hand pump

As already mentioned, this is the most common type of bicycle pump. The advantage is: large selection, low, which makes them affordable for every cyclist.

Floor standing bicycle pump

This is a very useful thing in the household of every cyclist who rides a lot, and is also simply irreplaceable for owners of road bikes (where you need to pump up the wheels to 7-8 or more atmospheres). Such a pump, of course, is not designed to be carried around. It will be in your home or garage and will allow you to quickly inflate the wheels without much effort. This is especially valuable if you have to frequently flip tires. Floor-standing pumps usually have a pressure gauge, which allows pumping to be performed accurately and not by eye. As in the case of hand pumps, floor pumps (if they are bicycle pumps) are universal, i.e. suitable for both presta and auto nipple.

CO2 pumps

A much less common type of bicycle pump, although it has a number of advantages. This pump does not require any physical effort when inflating and is quite comfortable in racing and cycling conditions due to the inflation speed. Also, its dimensions are very compact. The principle of operation is simple: a disposable CO2 cartridge is connected to the nozzle, the pump is put on the nipple and the wheel is pumped up to the required pressure rather quickly. Such a pump (for example, SKS Airgun CO2) allows you to inflate a mountain bike wheel approximately (depending on the size of the tire and the volume of the cylinder) up to 2.5-3 atmospheres, and for a road bike up to 7-8. The main advantages of the pump are its compact size and pumping speed. But the disadvantages are also quite significant 🙂 and cylinders (several hundred rubles), the weight of the cylinders and their disposability. It’s up to you to decide, of course, but personally I feel sorry for a few hundred rubles for one pumping of the wheel

Forklift pump (for shock absorbers) or high pressure pump

A good air suspension fork, and an advanced double suspension, is no longer a surprise to anyone. But air forks and shock absorbers are quite demanding to maintain, and also require maintaining a certain air pressure, which greatly affects the quality of their work. An ordinary pump is not your assistant here and you should pump up the shock absorbers with a special high-pressure pump with a pressure gauge (although there are models without it, but I don’t see much sense in them). Forklift pumps are usually quite compact and you can carry such a pump with you if necessary. In many cases, the pump is included with your fork or bike, but you may need to purchase it separately.

What brands should you pay attention to. How to use the universal hand bike pump

Since this type of pump is the most common, we will write for beginners how to use it correctly. So, we have the simplest universal pump without a hose. The first thing we need to do is determine which nipple is on our bike’s wheels. The most common types of nipples today are shredder (automotive nipple) or presta. As mentioned above, most manual bicycle pumps are universal, i.e. suitable for two types of nipples. The pump can have two holes at once, but most often there is one and the type of nipple is changed, in this case, by turning the parts in the pump head. How to do this should be indicated in the instructions for your pump.

After you have decided on the nipple and installed the parts in the desired direction, you need to unscrew the protective (plastic) nipple cap. Further, in the case of an auto-nipple, you simply put the pump on it and fix it with a special foot (if there is one), after which you inflate the wheel to the desired state. In the case of a presta type nipple, under the protective cap there is also a metal valve that must be unscrewed for inflation and do not forget to screw it back after. Having unscrewed it, you also put the pump on the nipple, fix and pump. In the event of a stalled nipple, be extremely careful and try not to move the pump too much during inflation, as that same valve is rather fragile and can be bent or even broken off.

As a conclusion, I would like to remind you once again that a bicycle pump is an essential tool for every cyclist, which must always be carried with you. You may be wondering whether or not to buy a floor pump for use at home, but a simple universal hand bike pump should be in your backpack or attached to the frame with a special mount (usually sold as a kit). You can also read the article, which describes how to change and glue the bike camera.

Pumping a bicycle wheel with a hand pump

No matter how many new ways to quickly inflate bicycle wheels appear, users of this transport are still interested in how to inflate a bicycle wheel with a hand pump. After all, it is this device that is included in the mandatory kit of the cyclist and can restore the transport’s ability to move. But you need not only to have a manual device for pumping air at hand, but also to be able to use it.

A hand pump is included in a must-have kit for a cyclist and will help to quickly restore the ability to move.

In general, such manual devices are divided into two types. The difference between them lies in the presence / absence of a device for measuring the pressure level inside the tire. a pressure gauge. It is better to buy a model with a pressure gauge if such a device is not lying around in your home. To make it easier to inflate bicycle tires in the future, you can calculate how many inlets you need to make to obtain optimal pressure. In this case, you can even do without a pressure gauge, but you will need to be careful and focused at each pumping, and this is not very convenient.

Inflation process

Every cyclist should know how to use a bicycle pump and be able to apply this knowledge in practice. To cope with this task, you need to perform a number of simple steps:

  • Scroll the wheel until the nipple is at the bottom. This is if the bike is in an upright position. In the event that the transport is lying or the wheel is dismantled, then the location of the nipple does not matter.
  • Unscrew the cap.
  • We deflate the tire, while holding the tongue from the nipple.
  • We insert the outlet pipe from the pump, and then turn the valve to the maximum level.
  • Install the pump in a vertical position.
  • We take the stem, lower and raise it with smooth movements, thus pumping air into the chamber.

Pressure control

Bicycle pressure gauge

It is important not only to know how to use a bicycle pump, but also to be able to control changes in air pressure. This can be done in several ways:

  • Using a pressure gauge, tracking the movement of the arrow.
  • If the pressure gauge is not connected to the pump, then periodically you will have to disconnect it and insert a measuring device into the nipple.
  • Feel the tire, while assessing its hardness.

The latter option must be performed even when using a pressure gauge. After all, the pressure in the pump during inflation may increase, and air will not enter the chamber at the same time. Accordingly, the readings of the pressure gauge will not correspond to reality and the wheel, as a result, will not be well inflated.

Assortment of nipples

Bicycles can be fitted with a variety of nipple options, of which not all will be suitable for conventional manual bicycle pumps. Automotive nipples and Dunlop are the most common. Thin wheels are often fitted with Presta valve elements. When working with such a valve, you need to be careful and clean. Such specimens are often found on road bikes and hybrids. Here it will be possible to bring the air pressure back to normal using a special pump, which is designed for a small volume. The use of a conventional pump will be possible due to a special adapter.

Riding a bicycle with flat tires is not permitted. It is not even worth thinking about such an option here. So that you do not have to drive your two-wheeled friend to the nearest place for inflating the wheels, you must always have a pump at hand and be able to use it.

Which is the best pump for a bike?

The bicycle pump is a separate type of positive displacement auto pump specially designed for inflating bicycle tires. It can have two heads or an adapter for connecting to one of the two most common types of bicycle nipples. Schrader or Presta. The third type of nipple is called the Woods valve (also called Dunlop), a bicycle tube with such a valve can be filled with a pump with a Presta head.

There are several main varieties of bicycle pumps:

  • Outdoor or automotive;
  • Fixed to the frame;
  • Manual or compact;
  • Foot;
  • Double acting.

The basic design of every bicycle pump is such that it can only function thanks to a manually operated piston. During the upstroke, this piston draws in air from the outside through an opening in the housing. During the next downstroke, the piston moves air from the pump to the bike chamber. Most floor pumps, also commonly referred to as automotive pumps, have a built-in pressure gauge to indicate the pressure in the chamber.

The electric pump is primarily designed to inflate car tires (as in most garages), but can in principle be used to inflate bicycle tires if the right type of coupling head is available. Some models of electric pumps cut off the inflation until a suitable pressure is reached (for a bicycle tire it is significantly higher than for a car tire), and the bicycle tire remains very weakly inflated.

Other models may not cut off inflation, but they provide too high a flow rate, which is needed to quickly fill a large car tire. There is a risk of over-inflating and bursting the bicycle tire if the powerful electric pump is not stopped within a fraction of a second after starting to build up pressure.

Bicycle pump types

If you ask yourself how to choose a pump for a bicycle, then their variety is limited to the main types.

There are three main types of bicycle pumps.

Floor pumps

Also known as automotive pumps. During operation, the user rests the base of this unit on the floor, steps with his feet on the base, pulls and pushes the handle at full speed. The connecting hose is screwed to the chamber through a one-way valve installed in the head or inside the auto pump.

It is very convenient to use such a product, since it has a fixed stop in the ground, and you can grasp its handle with both hands.

Hand pumps

There are two main types: with a hose and with an integrated head.

The hose pump has a separate tubing for connection to the chamber nipple. These devices have the advantage of being cheap but ineffective compared to other types. They have many connections through which air can escape.

Pumps with an integrated head have a rubber insert in the side hole, which is needed to seal the nipple around. Often, when connected, such a tab is crimped using a lever on the head. Since this elastic seals well, connects rigidly, and so that a hose is not needed, this type of product is very effective. An 8 “integral will generally pump the wheel faster than an 18” hose pump. But working with an integral type pump, without holding it with your free hand, there is a risk of pulling the nipple out of the chamber, especially the Presta design.

The simplest hand pump has a cup-shaped plastic or felt piston. When moving forward, the air presses the walls of this cup, just as tightly against the cylinder as the check valve. This piston can only push the air forward to the outlet at the opposite end.

The most efficient pumps are double-acting. Their piston is sealed on both sides in the cylinder and can force air into the tire during both strokes. forward and backward.

The small pump can be mounted on a frame bracket, on a clamp or screw, or on a soldered hanger, and can also be carried in a basket or bag on a bike, or in a backpack or cyclist .

Pumps carried on a bicycle are often quite small so as not to be heavy. But due to their small size, the amount of air they can supply is much understated compared to the floor-standing options. So it takes quite a lot of taps to pump up the wheel.

Foot pumps

These pumps are definitely not designed for road bikes. They do not generate enough pressure to keep narrow road tires running properly. But they are good for large, low pressure tires like mountain bikes.

Mostly designed more for cars, since they only have a head for Schrader valves. Therefore, you need a small brass adapter to use them on bicycle tubes with Presta valves.

Air Shock Absorber Pumps

A separate type, not related to inflating the wheels, is the high pressure pump. It is directly related to bicycle accessories, as it is the only one that can inflate the front fork’s air shock. It is impossible to do this with a conventional pump, but you can only finally bleed air from the shock absorber.

By the way, a pump designed for a bicycle fork can also pump the wheels. it has a hose with a threaded connection for a Schrader nipple. But they will have to work for a long time, because it is primarily needed to pump a small shock absorber cylinder, and not a wheel chamber, of a much larger volume.

High pressure pump start at 30. for good bicycle tire inflating pumps start at 20 and go up to about 30.

CO2 cartridges

Gas-filled bicycle cans are of unknown origin but appear to have emerged between the two world wars. One story has it that they were invented like this: one cyclist, after watching the owner of a cafe refuel bottles of beer, asked him to fill one bottle with carbon dioxide for himself.

The cans use liquefied gas, which cannot be pumped at home. The later versions, which are most successful, use cartridges originally sold for carbonating drinks. The inserted cartridge is punched by a lever, and the released gas is always enough to inflate one bicycle tire.

Modern gas cartridges are often used by mountain or road bike riders to keep weight low and save puncture time during the race. This can be a disposable balloon or a pump with a replaceable cartridge. Most use standard 16 gram carbon dioxide. CO2 threaded cylinders.

Carbon dioxide flows out through the rubber walls more intensively than air. Despite the fact that the CO2 molecules are large, they are weakly retained by the rubber, and after a few days the inflated wheel can become completely flat.

Electric pumps

12-volt air compressors designed for car tires are also compatible with bicycle tires. The portable car starter battery can be used to power these units. Even custom, homemade 12-volt electrical circuits, which are primarily made for bicycle lighting, can sometimes be used to power these pumps if they have a cigarette lighter socket.

The main advantage of electric pumps is that the latest models take up less space than hand or foot versions. In fact, there will be plenty of space in the electric pump basket. This makes them suitable for use on well-equipped e-bikes.

Tire pressure

The pressure rating is usually stamped somewhere on the side of the bike tire. It can be written in PSI (Pounds Per Square Inch) or in Bar bars. The pressure limitation can be labeled “Maximum Pressure” or “Inflate to” and is typically a pressure range (eg 90-120 PSI or 35-60 PSI). Inflating to the lower digit of the range increases grip and makes the ride more comfortable. Pumping to a higher figure makes the ride more efficient and reduces the chances of getting a puncture, but only a hard ride should be expected.

How to use a bike pump?

There is such a bicycle pump. How to use it? its main controls: a nut that is screwed onto the part that attaches to the wheel and a clamp. There is also such a pump. for him, the algorithm is as follows. put a pump on the nipple, then begin to open the clamp until the moment when the noise of air coming out of the wheel is heard. as soon as such a noise is heard. slightly cover the clamp and you can start swinging the piston by hand. after pumping with one hand, hold the piston until it stops and lower the clamp to its original position by quickly removing the pump from the wheel:

You put the pump on the nipple, open the clamp, pump up

I can’t put it on. apparently the nut is interfering? why is it needed? tried to unscrew it. then he just does not fight on the nipple

Try to turn over the plastic crap and gum that are clamped with a nut, in general this is a cool system you can turn over and swing another nipple.

usually there are two holes for nipples of different diameters, but if there is only one hole, then disassemble and turn the washer on the other side there are bicycle nipples. there are car

yes, exactly, if you turn the rubber band over, you can swing the old nipples. but I need a new one (but it doesn’t work out, to what extent should the nut be tightened? and to what extent should the clamp be opened? in the second pump it is necessary at about 45 degrees. if more, then all the air from the tire does not even have time to end up. then the air does not go into the tire not from it.I can not suck in any way, what is the principle of operation of this thing

On the one hand, there is a presta nipple, on the other, an autonipple. You turn the rubber band in the way you want, put it on the nipple (you don’t need to wind anything) until the nipple opens. Then you open the clamp (the elastic will grip the nipple tightly) and swing. The clamp usually opens fully to 90 degrees. As a last resort, go to youtube and find the video.

and how much to load the nut did not understand? if you do not tighten it, will the rubber still not grip the nipple? if screwed in all the way. it will not be put on?

the nut is always tightened, the tightness is regulated by the clamp

it won’t work. if you tighten the nut, then it flattens the gum in the waste, so that the hole becomes so narrow that the pump cannot be put on the nipple

Something, it seems to me, you are doing wrong. Perhaps you are inserting the adapter incorrectly. Here you can see how the presta is being pumped up (shown how the gum turns over). If you need an auto-nipple, insert it with the other side. However, you already showed in the first post that you disassembled the pump. So it’s strange that something doesn’t work out.

this is a feature and not a bug: everything is twisted, you put it in a closed state when the hole is big, you open it. it flattens out and squeezes the nipple, you can swing it

it looks like when you open it, the lever flattens the gum to narrow the hole. the nut does a similar action. if you screw it all the way, it bluntly flattens the gum so that the hole becomes so narrow that it is unrealistic to put it on the nipple.

one of the two following algorithms should help: I. 1) assemble the pump for thick nipples 2) unscrew the nut 3) put it on the nipple 4) tighten the nut, from this the rubber band will grip the nipple 5) swing 6) quickly unscrew the nut and remove the pump II. 1) assemble the pump for thick nipples 2) tighten the nut to the end 3) put it on the nipple 4) unscrew the nut, from this the gum will grip the nipple 5) swing 6) quickly tighten the nut and remove the pump if both algorithms did not work, then maybe this not a pump, but shit I had shit of this design, it could pump up to half the atmosphere, and then I went to the store and said that either let them demonstrate it in work, or let them give the money back

that is, the clamp lever can be left alone? and poisoned where. right in the piston? it was impossible to just plug the hole so as not to poison?

why, then, a pump with three cants (it has no nut, but with two outputs) works normally only with a lever of 45 degrees, if less, it simply does not pump, if more (under 90), it wildly poison?

And what position do you take for 0?

As far as I know, there is no non-return valve in the car. does it mean it is in the pump? where is he in that pump? Could it be that I lost it when I unscrewed the nut and put the rubber band in the correct position? Or is it somewhere inside the pump and cannot be lost? or it doesn’t exist at all?

now I tried to blow my mouth into the pump in the opposite direction. the air quietly leaves somewhere in the area of ​​the arm. it turns out when I put the pump on the nipple all the air from the wheel instantly comes out of it in the same way? that’s why it doesn’t work for the campaign. no check valve.

You were asked the right question here. You have a lever when you screw the nut. in what position?

I have the same pump as in the picture. I bought it at Decathlon. But I also bought a tube that hung nearby. The tubing pump works fine. Without a tube, I could not assemble the pump so that it would pump the wheel with a nipple.

The tube turns out to be called a hose. Here is this http://www.decathlon.ru/shlang-dl-ruchnogo-nasosa-id_5553480.html And the air will escape a little until the structure is completely assembled and screwed onto the nipple.

The valve doesn’t seem to turn on. If it is in the pump (and it should be either in the pump or in the hose), it works constantly. Until you tighten the gum around the nipple with a lever, the air is poisoning through the junction. So either your valve in the pump is broken, or you really have this type of pump where the valve in the hose should be. You can’t pump without a valve. There are no valves in either the auto nipples or the presta. here you are right.

Yes, now I checked it on the second normal pump. I blow into it, nothing comes out of nowhere. then this pump is broken, most likely, since air in it poisons from where it should be sucked in.

Try to make it out. On a fairly common pump from cyclodesign, this is done by knocking out the pin and getting the valve and rubber band http://i.imgur.com/uowbqio.jpg

Well, you can assume that the pump is broken. But, in my opinion, he will “fix” the hose.

The nipple itself is a valve but when the pump is on it is open. According to the description, the pump is broken, nothing should come out through the handle.

Yes, he said bullshit. Thanks for correcting. Of course, a nipple is a valve, otherwise it would not hold air =) It means that the nipple does not have such a “valve” (or is it somehow called something else? Which would let air through only in one direction. Upd and offtop. I tried to understand the terminology and technologies. The nipple is essentially a check valve (which seems to follow from the definition). Then it’s not entirely clear to me why the bicycle pumps press this valve and open it (and the check valve in the pump itself is activated). the nipple will not open itself by the air flow?

Yes, thanks for the clarification. Opened Wikipedia, read more about the car nipple. http://ru.wikipedia.org/wiki/%D0%9A%D0%BB%D0%B0%D0%BF%D0%B0. It clearly states that “Another disadvantage of the Schrader valve is that the opening is carried out by pressing the valve stem, and the Schrader valve itself is not a check valve. some air is lost when connecting and disconnecting the pump hose, although this is the norm, in while the Presta valve is only opened by directly supplying air into the chamber. ” Regarding the position of the valve. in the picture that I found (where the pin is knocked out), it turns out that it is located immediately after the elastic.

press because in order to push through the resistance of the spring, the pressure needs much more than that to which the wheels are usually pumped. Atmospheres 10

Well, that is, by definition, he is still a “check valve” and Wikipedia is lying? If air is supplied under high pressure, it will push?

will push, of course, it is obvious even from the picture on Wikipedia. How can you not push through. But the pressure needs a lot.

Here, too, the picture hints to me that this is also a check valve.. can you tell what you’re leaning on when you say that shrader is not a check valve? The fact that it is not used as a check valve when a bicycle pump is used (and it opens mechanically stupidly) is understandable. Therefore, an additional check valve is needed in the pump itself. But by definition, sort of. By the way, I have presta nipples on my bike and they also open by pressing (at least with my pump) and the pump check valve is activated, which is why I argued that there are no one-way valves in Presta either.

Why always? Why can’t it be possible to open the nipple by mechanical action? On this video, dunlop at 13 seconds unscrew the nut and it starts to release air

well, in such intricacies of terminology, I no longer understand) the fact is that when it is necessary. namely, during the pumping process, it is not and when it is not necessary (that is, when I just ride the bike and don’t pump anything) I don’t care what he is. reverse or not. you can at least just use an ordinary valve with the same success and open it if necessary, pump it up and then close it.

Ok, thanks for the topic =) I managed to figure out some of the subtleties, interesting. I hope you can figure out the pump.

the bike pump works fine I don’t understand how the pressure gauge works explain

How to pump up a wheel with a bicycle pump

Hello! My name is Darina, I am an illustrator and graphic designer, recently I was fond of cycling around the city and now I am writing about my experience in It’s my! Bike.

When I was 10 years old, I rode a bicycle in the country house. it was my only and favorite transport to fly through the fields and get to friends, dash away from a scary abandoned house or quickly drive home under an owl ooh in the dark. Probably like many.

After that, for 12 years, I almost never used a bicycle (but secretly dreamed of going to the market and in a skirt with a wicker basket and a skirt). in the center I was scared to drive next to cars, and on the sidewalks it was unbearably slow. Everything changed when I fell in love, and my friend, and now my husband, gave me a blue road bike and for the first week accompanied me on all my routes. in the morning to work, in the evening for salsa, on weekends to explore the markets and bike paths, because I was alone it’s so scary to drive next to the humming cars! When I got used to it and felt equal on the road, just like the driver of a car, I realized that there is no better transport, and now I talk about how life changes when you ride a bike (go to the nearest park for lunch from work, overtake a traffic jam. get Pavlova’s posture, improve concentration). Plus, I’m so impressed with Copenhagen, which has more bicycles than pigeons, that I wish it were the same. Every day I choose a bike and tell you why.

When I ride my bike, it rarely happens to me that the wheels are flat and I need to pump them up: every morning I go out with a pump to the yard where my bike lives and check the elasticity of the wheels. I check them ingenuously. I feel the tire around the entire circumference and if it bends somewhere, then you need to tone it up.

Pumping up a wheel with a hand pump is not difficult, and even mischievous. you immediately remember how in the country before you drive off for the whole day you quickly and quickly pump up your bike and fly out of the yard with a bullet.

I spin the wheel so that the nipple (the very process on the wheel) is on the side. Almost all modern pumps have two holes. a larger and a smaller one for two types of nipples, I think you will see which one suits you.

I unscrew the nipple cap, put the pump on it, lower the pump lever down and fill the tire with air (almost morning exercises are obtained, especially if you pump not only with your hands, but with your whole body weight) Now we snap the lever back, remove the pump and tighten the cap on the nipple. Finally you can rush on business.

I try to find a balance in this matter. if I don’t finish it, then it’s hard to drive, and I’m angry that the wheel is almost dragging on the asphalt, I have to put a lot of effort, and the wheel is rubbing. If you are pumping, then the tire may burst from the glass or jumping onto the curb. There is no ideal recipe, as in luck, with inflating the wheels, but on the side of the wheels is written the maximum to which you can pump the tires. Most pumps have a pressure gauge and it is better to choose a pump with it, because there you will see exactly how much more you need to pump up the wheel for an easy ride.

Pumps with a pressure gauge are available on the It’s my! Bike website
