How To True A Bike Wheel Without A Truing Stand

methodological developments, presentations and notes

The purpose of the master class: 1. Mastering and subsequent active application of technology in the practical activities of a teacher-educator. 2. Improving the educational process to expand.

“Children and the Road”. this is the Program of educational work of preschool teachers and children of younger, middle and senior preschool age with the involvement of parents (legal representatives) of pupils.

The study of traffic rules in preschool age, forms and methods of work.

It is at this stage that it is important to form in children a model of safe behavior on the roads, streets and in transport, which allows them to act adequately to a specific real road situation.

Target section of the program. 2. Substantive section of the program. 3. Organizational section of the program. 4. Additional section of the program. 5. Bibliographic list.

Speech on teaching preschoolers traffic rules using the method of problem situations.

The purpose of the program is to create conditions in the preschool educational institution that optimally ensure the process of teaching preschoolers to the rules of the road and the formation of the necessary skills and abilities in them, the development of positive.

Foreign body in the tire

After a puncture, the camera was sealed using a flipper tape, but the working element is still constantly lowered. Perhaps, a shard of glass remained in the tire. It is difficult to detect and constantly creates problems for the cyclist.

On a note! Before boarding, carefully check the wheel for small stones, glass and other foreign debris.

When beading and disassembling a wheel, you need to use a special tool. a beading blade. Discard screwdrivers, keys and so on.

Worn tire

Most often, a bicycle is deflating a wheel that has served its life. The surface of the tire becomes more viscous, collecting various debris, small glass and so on. All the little things gradually penetrate inside, right up to the camera. As a result. another puncture.

In addition, holes are formed on the worn rubber, into which the bicycle tube is visible when inflated. It can simply come into contact with the road when driving. This will inevitably lead to another unpleasant situation.

We eliminate the problem correctly

You need to remove the camera. Pump it up and grease it with glue. Then apply to the patch. Wait for the glue to set, and after 5 minutes the camera can be mounted.

Tape designed to prevent punctures

Indeed, protective tape can be source of problems. It is tough, with sharp edges. If not installed correctly, the camera can be cut.

Note! Constant use of an anti-puncture tube reduces tire wear resistance.

Why flattens a wheel on a bicycle

Problems associated with the wheels constantly accompany outdoor enthusiasts and athletes. If a whole staff of employees is involved in the maintenance of bikes for professionals, then amateurs have to independently decide why they deflate a wheel on a bicycle.

An annoying nuisance that seems impossible to avoid. But this is only at first glance. Often we ourselves are to blame for the flat tire of the bicycle. What is it about?

Working element pumped over

Another reason for deflating a wheel on a bicycle. From the inside, the rim is glued with a flipper tape. It is she who protects the camera. The pumped-up element may break the flipper or burst.

What to do if the camera goes down

If, after you have sealed the puncture on the bicycle tube, it still lowers over time, then you should check:

  • Does the air poison from under the patch? To do this, the place with the patch should be immersed in water and make sure there are no air bubbles. If they are, then you will have to tear off the old one and glue a new patch.
  • Check for other, smaller punctures by lowering the camera in water. If found, glue.
  • Check for air leaks through the nipple. To do this, you should spit on it (or, if you do everything correctly, apply a soapy solution) and observe for several tens of seconds. If it passes, then bubbles will form on it. In case of leakage, tighten the nipple with a special wrench.
  • Whether the metallized cord has come out. It happens that over time on cheap bicycle tires the cord breaks down, which is a thin wire (more expensive tires use nylon threads and other materials), which can crawl out from the inside of the tire and constantly pierce the tube. If such a problem is found, the tire should be replaced as soon as possible. A temporary solution is to pull out the protruding cord wire and seal this place with a patch for the camera. But I repeat that in this case a tire replacement is required. this will be repeated regularly.

If the chamber is damaged at the base of the nipple (for example, it is frayed with the rim), then it is better to replace it immediately. As a rule, such defects cannot be repaired.

How can you glue the camera

Not any glue or patch will work for fixing a puncture on a bicycle wheel. Therefore, it is worthwhile to dwell in more detail on the topic of what can and should not be used to glue the bike’s camera. There are several options, which we will consider below.

  • Specialized repair kits. Many bicycle parts manufacturers produce so-called bicycle camera repair kits, which are usually a box, a crayon to mark the puncture site, a sander (usually a metal perforated plate or a piece of sandpaper), several patches of different shapes and sizes, and glue. The composition of the glue is specially designed for joint use with the surface of specific patches (with which it enters into a chemical reaction), therefore, using it in conjunction with patches from another manufacturer may not give a result. Fortunately, in most of these repair kits, the amount of glue is clearly calculated for the number of patches.
  • Chinese bicycle camera repair kits. Some riders underestimate the power of the Chinese industry and look at their harnesses with disdain. I can’t talk about everything (I’m sure that some of them are really terrible), but for the last 4 years I have been using exclusively Chinese patches from Red Sun (although this may not be a company, but the name of a repair kit). They are quite common. For several years of use, none of the patches flew off and did not allow air to pass through. And the cost of this product is lower than that of famous brands. The disadvantages include that the set contains only glue and patches, and what is most offensive, patch is incommensurably more than glue. Well, these are little things. In general, I advise everyone.
  • The third option is the most unreliable and therefore should only be used as a last resort. Here we have highlighted homemade patches that can be made from an old bicycle camera. Almost any plastic glue for rubber can be used as an adhesive. But in this case, the reliability of the patch is very low. Here they say so, “at your own peril and risk.” When using homemade patches, you cannot use glue, which, when hardened, can burst in places of bending.
  • Curing. It sounds good, it turns out very reliably (better than using any glue and patches, considering that you vulcanize in a specialized workshop), but in fact it is not worth the money and the hassle. It is quite difficult to do at home (and impossible in the field) and you can easily screw up the camera.

How to stick the patch correctly

After we have found and marked the puncture site of the bicycle tube, we should start repairing it, namely, glue this hole. To do this, you need to perform the following operations.

  • If the chamber is wet (after searching for a defect), then wait until it is completely dry. Plus, it must be completely deflated.
  • Using sandpaper or a special perforated iron plate (which is usually found in bicycle kits for repairing cameras), we clean the puncture site until a matte color appears. The sanding area should be 1 cm larger than the diameter of the bicycle patch. After this procedure, we try not to touch this place with our hands or other objects.
  • Remove the protective film from the surface of the patch, which we will glue to the camera.
  • We apply glue. It can be applied only to the patch, only to the camera, or both. This information can be viewed on the glue tube. We also draw attention to the exposure time in air indicated in the same place and the time of complete solidification (the last two points may not be indicated).

How to determine the puncture site

At first glance, a very simple procedure for identifying a puncture site can be significantly complicated depending on where you find a flat tire (at home or while driving). To simplify the search procedure, it should be borne in mind that in 90% of cases it is located on the so-called “contact patch” of the wheel with the road, usually no higher than 2/3 of the camera height. An exception may be damage from the rim (if the rim tape is out of order on the latter) or crawled out iron threads of the tire cord. Therefore, we will consider several options for how to find the hole in the bicycle chamber through which air is released.

  • The easiest way is to lower the camera into the water. It is enough to have an insignificant tank, the depth of which allows it to be immersed at least 2/3 of its height. We rotate the camera until we find air bubbles that will burst out of the water. After we take it out, we find the puncture site and proceed to repair.
  • If there is no water nearby, then fine dust (which can be found on unpaved roads) will come to the rescue. We increase the pressure in the chamber to strengthen the air stream from the hole and bring it a short distance to the dust (without touching it). We rotate the camera and look at the place where the dust begins to scatter.
  • If the weather is calm outside, the puncture can be detected by holding the camera to the wet wrist (the inside of it). The skin should be wet to make the search as easy as possible. For this method, it is also desirable to increase the pressure.
  • With a strong puncture in a quiet place, it can be detected by ear.

Bicycle camera repair, how and how you can glue the puncture

Sooner or later, every cyclist experiences such an unpleasant situation as a puncture of the bicycle camera. If you find that a wheel has flattened at home is one thing (although it also requires some knowledge of camera repair), but what if you punctured it during a multi-kilometer ride, for example, somewhere in the field? How to determine the puncture site in such a situation, correctly change and glue the bicycle camera, what glue and patches are best suited for this purpose. Additionally, in this article, we will consider some of the nuances of repair and proper operation of bicycle cameras, for example, we will talk about what pressure should be in them and much more.

  • Maintain the working pressure in the wheel at the required level. There is no specific figure here, since the nominal working pressure may differ for certain tubes / tires. For example, on mountain bikes the pressure in the chamber should be about 2.5-5 bar, and on road bikes it should be 6-9 bar. The bicycle tire has corresponding minimum and maximum pressure labels. It looks something like this. If the pressure is too low, it greatly increases the risk of puncture. It is worth remembering that when driving in winter or in the autumn-spring period, the temperature outside is lower than in the apartment. Therefore, on cold days, the chamber should be inflated a little more (because when the air temperature in a closed volume decreases, its pressure decreases). Therefore, if you pump up to 3 bar in the summer, then in winter you can increase the pressure by about 1 bar (but not higher than the maximum allowable).
  • Change tires after wear. With the depletion of its resource (wear of the tread), the probability of a puncture also increases. And if you have a worn out tire, and you began to notice that the wheel began to break through more and more often, you should think about replacing the tire.

On the bicycle parts market, you can find two more devices that are designed to simplify life (at least, they position themselves this way) when cycling. This is an anti-puncture tape and sealant, which is poured in a small amount into the chamber and is designed to “tighten” punctures while driving.

Anti-puncture tape is a strip of soft, rubberized plastic or, in more expensive products, Kevlar, which can be glued or simply inserted between the tire and the bicycle tube and protect against punctures. But there are pitfalls here. A cheap anti-puncture, firstly, does not always protect against punctures, and secondly, it can fall apart inside the tire and grind the camera into dust with its fragments, thereby dooming the latter to ejection. Plus, it’s overweight. In general, after sitting on the forums, I agreed that they are more hayut than praised.

As for the sealant, it’s not so good either. As a temporary solution, when you do not want to bother with replacing the camera, of course, you can use it. But the sealant does not seal the puncture completely, but only reduces air leakage. Plus, there were complaints after use, when they wanted to stick a patch on the puncture site.

In general, according to the editors, it is better to use better quality bicycle tires with built-in puncture protection, carry a spare camera with you and not bother with the above accessories.

Bicycle carriage creaks

One of the most common ailments. The carriage squeaks when it is very wet or unwound. The source of the squeak is the carriage thread. It is characterized by the fact that it occurs at the moment of intensive pedaling and looks more like a crunch than a creak. Sometimes it seems that in the center of the bike something has come off and continues to hamster. In addition, this nasty sound can also be emitted by an unscrewed connecting rod, which walks on its landing point. Both problems are treated by disassembling the entire assembly, wiping the threads, applying graphite or lithol to it, and pulling back. Sometimes it is enough to tighten a careless connecting rod bolt or bottom bracket indiscriminately. But if we have already reached this point, then it is better to drag everything.

It is especially fun for the owners of old non-cartridge carriages. They are hard to twist, but they loosen and squeak many times stronger. By the way, the mechanism itself will also be useful to miss.

Bicycle chain creaks

The bike chain squeaks if it is not lubricated in time or if its wear is very high. How to lubricate the chain, we have already read in this article.

The squeak of the chain is easy to recognize and has a drawling nasty sibilant character.

What to do if your bike squeaks

Any bike needs maintenance. If the bike squeaks, it means that you completely forgot about repairing the bike. But moral reading is not our goal at all. We need to figure out what to do if the bike squeaks and how to figure out what exactly squeaks in the bike.

I will say right away that this article is focused more on beginners than on those who like to constantly pedal. Therefore, we will use simplified formulations, and keep the style of the article simplified. Although, jokes are jokes, and at one time I spent a lot of time to figure out why my bike squeaks. It turned out that the reason was trivial. But everything is in order.

Bicycle wheel creaks

A bicycle wheel most often squeaks due to washing out of the grease in the wheel hub. If the grease was grease, then you need to grease the wheel again. If it was liquid, then the bushing need not even be disassembled. If the bushing misses, then a whistle, this is a normal condition indicating that the bushing is worn out (but not broken). Lubricate the bushing with liquid grease.

If there is any doubt about the bushing adjustment, then check the axle mobility. The wheel should rotate without snagging or cracking. After all, a creak sometimes appears precisely because of the tightened sleeve.

Bicycle fork creaks

This trouble was inherent mainly in the old spring forks. Build quality was not particularly good, with the spring inside shaking and brushing against the sides of the fork inside. Any stops and parts moved relative to each other. So the effect of an old sofa was obtained. Modern wikis are no longer creaky. If a modern fork creaks, then you need to sort it out and if it is oily, then change all the oil inside and flush the valves. You also need to apply silicone to the oil seals.

In general, this problem occurs, but a strong squeak will bother you only on budget forks.

Bicycle shock absorber creaks

The situation is similar to the creak of a bicycle fork. A spring or a point of contact may creak. In addition, the fixing points of the shock absorber in the frame very, very often creak. They need to be pulled up first.

Also, don’t forget that inexpensive shock absorbers squeak straight from the factory. It is almost impossible to eliminate this creak.
