Why remove and raise / lower the steering wheel?
Before we come to the question of how to raise and lower, remove and put back the handlebars on a bicycle, let’s decide why this is usually done? Let’s not be distracted by the not-so-frequent cases when the bicycle wheel has broken down and needs to be replaced. It is already obvious that in cases of repair, a broken bicycle handlebar will have to be removed and replaced with a new one. In the overwhelming majority of cases, manipulations with the height of the bicycle handlebar are resorted to to regulate the height of the rider’s seating position.
The zero, or universal level of a bicycle handlebar is considered to be its height, which is equal to the height of the saddle. If the level of grip on the handlebars is higher than the level of the saddle, the handlebars on the bike are considered high. If the hand grip is below the level of the saddle, the handlebar is considered low. The interdependencies are as follows:

- the higher the handlebars, the straighter the cyclist’s seating position, the more relaxed the back and arms, and the more comfortable but slower cycling. This position is suitable for long and comfortable riding, but not suitable for high-speed.
- the lower the handlebar, the lower the position of the cyclist’s body, closer to the horizontal, aerodynamically streamlined, the ergonomics of the muscle frame approaches the most effective, but the muscles of the back and arms in this position are constantly tense. This position of the cyclist is used for short-term high-speed riding, but is not suitable for prolonged stay in the bike.
Types of mounting a bicycle handlebar
It turns out that the design of the bicycle handlebar mount is different, so the approach to its height adjustment is also different for different types of bicycles.
Threaded mount, with the stem secured in the steering column using a wedge lock. This design is most often used on budget, but the most popular city bikes or road bikes. It is characterized by the simplicity and clarity of the approach to the issue of removing, installing, adjusting the bicycle wheel in height. But this design is heavy, and therefore it is not used on sports bicycles popular today.
Threadless fastening, with the stem fixing in the steering column using an expanding anchor, and additionally with a stem clamping collar. This bicycle handlebar design is characterized by its structural simplicity and lightness. Most often used on modern sports bicycles. But in the matter of adjusting the steering wheel in height, it is characterized by ambiguity and multivariate approaches.
Removal, installation and height adjustment of the steering wheel with a threaded fastening
In order to remove or adjust such a bicycle wheel in height, you must:
- using a wrench of the appropriate size, loosen the fixing nut on the top of the steering tube;
- use a wrench of the appropriate size to loosen the expansion screw of the wedge-retainer (in the upper end of the structure) so that there is a play in the bicycle steering wheel attachment;
pull out the steering wheel assembly and remove it from the steering tube, or adjust it to the installation height (raise or lower), then tighten the wedge-retainer screw and the fastening nut in sequence.
Removal, installation and height adjustment of a handlebar with a threadless mount
In this design, removing / installing a bicycle wheel and adjusting it in height are often different concepts and operations.
With the removal and installation of such a bicycle handlebar, everything is more or less clear and monotonous, it must actually be disassembled into parts:
- loosen the armature screw (at the upper end of the steering tube) with a hex wrench;
- we also loosen the stem clamp screws with a hexagon or wrench;
- remove the stem with the steering bar assembly.
But the regulation of its height is not so unambiguous, and has options:
- After removing the steering wheel, by placing washers-spacers between the stem and the head tube. But the range of such adjustment is insignificant, limited to a few centimeters.
- By purchasing an adjustable stem. Everything is clear here. on such a stem, the adjustment is made by a built-in mechanism (there are different designs), easily and quickly, literally on the go or at a short stop.
- By adjusting the stem height. Conceptually, everything is simple. a new stem of the required height is bought, the old and new stem are swapped. But you won’t be able to do it quickly. maximum, just before each trip.
- By selecting the steering bar, according to the lifting height of the handles. The principle is the same as in the selection of the stem. I bought the right steering wheel, installed it, took a ride, got tired. replaced it with another one, with a different lifting height of the handles.
Thus, if you have a sports bike and would like to be able to change its height adjustment quickly, right while riding, there is practically no alternative to an adjustable stem. Although, as an option, you can purchase and install a multi-position bicycle wheel. a ram, a butterfly and others. Multi-position handlebars allow you to get away from the problem of changing the position (position) of the cyclist during the trip even easier than the adjustable stem.
How to remove a chain without a lock?
First of all, you need to choose a link that will be sorted out. If this happens for the first time, it does not matter what it will be, if possible, look for the link with which the chain was connected at the manufacturer’s factory (as a rule, it stands out). However, if this has already happened before, it is very important to choose a new one, and not the link that was dismantled, otherwise the probability of rupture increases.
Next, we arm ourselves with squeeze. This is a special tool like a miniature press with the same extrusion wedge. We install the selected link in the squeeze, carefully fix and squeeze out the axle using the rotating handle of the press. It is strictly not recommended to extrude the axle to the end if you do not plan to replace it, otherwise it will be very problematic to insert it into its original place. It should remain in the opening on the back of the link cheek, so that there is room in the middle. The chain is removed. For the installation process, everything happens the same, only in reverse order.
How to remove a bicycle chain?
The bicycle chain is one of the key transmission units of any bike, which directly transfers the rotational-translational energy of the rider’s legs to the rear wheel, which sets the entire unit in motion. In this case, the chain is subjected to the most intensive work and various external influences of a destructive nature, which means that it needs careful care, prevention and ensuring the initial working condition.
Depending on the conditions of use of the bike, if it happens occasionally in favorable sunny weather, you can limit yourself to simply cleaning and lubricating the chain without removing it. But when riding happens regularly with extreme elements, including rough terrain, landscapes, rainy, windy weather, etc., regular wear and tear occurs and the need to remove the chain from the node for thorough washing from dirt in special solutions, lubrication, possibly a complete replacement or in separate cases. adjusting its length.
You need to know that bicycle chains are produced only taking into account the compatibility of various transmissions and are available with or without a coupling lock and, accordingly, are called locking or clamping. A separate global manufacturer tries to develop its own sound technologies, proprietary developments in connecting mechanisms and implements in each model, adhering to certain principles.
Chains with a lock are considered more practical, especially in assembly and disassembly, which do not require much effort. Clamping devices represent a monolithic structure, which means it is more reliable, but they assume the presence of a special tool. squeeze, the handling of which requires experience and work skills, which is hardly suitable for beginners.
How to remove the lock from a bicycle chain?
Carefully inspect all the links of the chain, usually the lock has a prominent shape with more enlarged holes for pins, or in the form of an elongated horseshoe, an elongated oval and similar nuances. You will need to loosen the chain in the area of the lock, this method is also great for installation. For convenience, you can use a wire or make a bracket out of it and fix it on the links on both sides of the lock so that it sags down, somewhere two or three links from the connection, and more, as it is convenient for you. To keep the chains in a slack state, special holders are sold, you can use them. Further, if you cannot remove / fasten the lock manually, then use ordinary pliers and slide the pins (axles, pins) on each half of the lock cheeks. the circuit will open. There are on sale special pliers in the form of a movable trident for opening and closing locks, which can be purchased, it will be easy to work with them.
How to remove a chain from a bicycle without squeezing?
Dismantling the chain without a puller is considered vandal and such a bicycle chain will be loosened at the point of separation by improvised means. But how to do it. we will tell you in this article.
- We start by loosening the tension by removing the chain from the cranks and putting the bike on its side (which is no longer good, you can damage the paint).
- We spread the chain so that you can knock out the pin. It can be a bushing of a small diameter, a nut, two objects lying at a short distance from each other…. Anything…. We turn on imagination and ingenuity.
- We take a hammer and a tip slightly smaller in diameter than the pin. and gradually knock it out. We knock out not completely so that it does not fall out. This will make it easier to put the chain back together.
How to Remove and Install Schwinn Kickstands
But with the modest cost of the simplest, one-time squeeze, it is better to use it. With an inexpensive tool, we handle it carefully so as not to bend the squeezing pin on the squeeze. This way you can remove the chain more than once.
How to remove a figure eight on a bicycle wheel
If you prefer to actively use your bike for its intended purpose, and it does not collect dust in your pantry and garage, then you probably had to deal with the problem of wheel alignment. This is a minor problem for an experienced cyclist, but it can be quite embarrassing for a beginner cyclist. It’s good if you find a breakdown at home and can return the bike for repair. In any bicycle workshop, within a maximum of an hour, the figure eight on the bicycle wheel will be removed. The cost of this kind of services on average ranges from 50 to 200 UAH, depending on the curvature of the wheel. But if this problem arose in the field, or you often encounter it, then this article will help you fix it yourself, without anyone’s help.
.Prevention of breakdown and the causes of its occurrence
It doesn’t matter if the rear or front wheel is bent, it is equally dangerous not only for the bike, but also for your health. It should be understood that using a wheel with a bent rim is fraught with:
- Broken brakes on your bike.
- Wheel hub loosening.
- Prolonged use may cause the spokes to become unusable.
- Calm and tidy cross-country driving.
- Adjust the spokes on each wheel every six months.
You should pay attention to the fact that if you prefer an aggressive driving style and are used to passing obstacles at maximum speed, then the adjustment should be carried out at least once a month.
.Selection of tools and materials for home repair
The most important tool in this business is the spoke wrench, with which you can adjust the tension on the spokes on your bike. In the absence of this, you can use pliers, but in this case there is a high chance of disrupting the thread on the spoke. It is best to customize the key to the size of your bike‘s spitz, rather than its universal counterpart. Also, in order to fix the figure eight on a bicycle wheel, you will need a marker or chalk to fix the places with deformation.
Detailed, step-by-step instructions for centering the wheel on a bicycle.
Also worth mentioning is the so-called forceful method of aligning the wheel of a bicycle. In this case, place the wheel with its curved part on a flat, hard surface and press firmly on it. The main disadvantage of this approach is the high risk of ditching the wheel.
Wheels, handlebars, pedals and a saddle attached to the frame. this is how a bicycle is depicted on diagrams or signs, for example, bicycle parking. In fact, a bike, even the simplest one, is equipped with various attributes, both necessary and not so. These include everything from a trunk with fenders to a bell, a rear-view mirror and a parking stand.
A footrest is a special accessory for a bicycle that gives it a stable position when stationary. There is often debate among cyclists about the usefulness of this device: some simply cannot live without a footrest, but others do not need it at all. over, they even take it off the bike they just bought. And if you look at it from an objective point of view? To what extent this accessory justifies itself, we will consider further.
Bicycle stand: where you need it, and where not
The expediency of using a footboard is determined based on the conditions of movement. The main areas of use of the two-wheeled horse:
- Relaxing rides in parks, sidewalks and paths.
- City road trips.
- Moving on the highway.
- Cycling: city and cross country cycling (hills, forest roads).
- Cycling in various directions.
For the representatives of the first group, a bicycle footboard will perfectly serve as an attribute for beauty. Indeed, with simple measured trips around courtyards, parks or playgrounds, there is no particular point in putting a great. As a last resort, you can hold it behind the wheel or lean against something (a tree or a post, for example). Although, if there is a stand, you can sometimes use it and not remove it from the bike: it does not ask for food, and its absence is not important.
The next group is cyclists who ride city bikes around the city. road bicycles with one or more gears or with an installed planetary gear system. As a rule, the footrest is installed on them by the manufacturer.
Moving on to the highways. Anyone who has tried to lift a road bike has always wondered how light it is. Almost complete absence of accessories: there is no bulky trunk, shields, mirrors and bells. There will be no footrest here either. What’s the matter? At high speeds, the weight of the bike is very important: the lower it is, the easier it is for the cyclist to accelerate on asphalt and coast. But how much does this stand weigh? Hardly more than a pound, right? Yes, it is absolutely correct, however, every gram is important for highways, because when driving, its effect on speed increases significantly!
What if you need to park? There are two options: put the bike on the ground and close the rear wheel with an anti-theft cord, or tie the bike frame to a post, pipe, tree, or, if there is a bike parking, drop the bike on it.
Cycling tourism is a popular hobby among lovers of two-wheeled vehicles. Perhaps the importance of a bicycle footboard in this area can hardly be overestimated. Cross-country driving is associated with constant obstacles: the roads are uneven and surrounded by dense grass, ravines, steep slopes. If the bike is put on the same track when stopping, it may interfere with other cyclists or cars. The kickstand will help you position the bike off the side of the road, and even if it gets in the way, it’s very easy to move.
The stand allows bike travelers to position the bike evenly when the trunk is heavily loaded and serves as a support around which the weight of the entire load is distributed. It is only important to find a hard surface, especially if the heel area is small.
Among biker travelers, most of the bike stands on a stand whenever it is necessary to get off it to rest, have a snack, take pictures of the area or inspect for malfunctions.
Do i need a kickstand on a sports bike? In principle, if it stands idle for a long time, then yes. But in the process of cycling competitions, she is simply removed from the bikes: she is unnecessarily. For example, why should she be on extreme descents from the mountain (downhill), when the cyclist simply will not stop and even more so, set the bike. The same goes for bicycles used in BMX: dancing on two wheels, tricks on a dirt track, vert, street.
Varieties of footrests
The classification of devices is outrageously simple: there are carriage, rear-wheel, two-legged footpegs and stands under the frame.
City bikes designed for city and flat terrain are already equipped with the first type of footpegs. They are located in the area of the carriage mechanism and keep the bike in an inclined position. As a rule, the heel of such footpegs is small, which does not allow the bike to stand in the sand or on scattered small stones. Such stands do not withstand a large load, especially on the trunk, but they perfectly allow you to balance a large one if you hang a bag or backpack on the steering wheel from the opposite (mainly right) side.
Sometimes on road bikes you can see stands attached to the drive wheel. They are also present on mountain bikes. With this support, you can load the rack: all the weight falls on the rear wheel, and the rest of the bike resists falling. This option is good for tourists: in addition to the knapsack on the trunk, you can also hang the backpack on the steering wheel on the other side, and load the middle part of the frame from it.
Rear stands are not always attached to the wheel axle. They can also be placed on the pen and the distance from the rear wheel can be adjusted.
Bipedal symmetrical supplies are very similar to their counterparts mounted on motorcycles. They resemble flyers in shape. A bike with this kickstand stands with a slightly raised front wheel. The weight of the bike and the load on it is evenly distributed between the stand and the rear wheel. Distinctive features are the level position of the standing bike and the large area of the stubborn heels. Disadvantages: rather large weight, about 600 grams. However, with a 20-kilogram backpack, this weighting will not be too noticeable.
And finally, let’s get acquainted with the so-called long footrest, or stands under the frame. In shape, it is a tight long pin with flyers along the edges: one for securing the frame, the other with stops for installation on the ground. Also an excellent option for travelers, but absolutely pointless when used on city bikes.
The bike stands level, and the weight and load on it are evenly distributed between the front and rear of the bike, thanks to the connection of the middle of the frame to the road surface. It is better to use on hard surfaces, in sands the stand can get stuck and lose stability.
Nevertheless, with a few exceptions, a bicycle footboard is a useful attribute that will not interfere with it on the road and will help to place a two-wheeled horse, and not dismissively put it on the ground or lean against something. However, how to handle the bike. to put it on, lay it down or lean against it. this is a matter of habit, the main thing is that it does not cause any inconvenience.
