each of us back in the childhood had to pull a bicycle chain.The design of the old bike was not perfect, so this element often flew.Since then, it took a lot of time, and innovations that came to cycling industry have changed beyond recognition mechanisms.It is already difficult to meet the transmission type "singlspid", and until recently, the popular eight-transfer thing of the past.
Now bikes are equipped with nine stars and a thin chain that require regular maintenance - this is the price paid for the transfer of comfort, speed and light weight.Consider, what rules should be followed to install the chain on a bicycle was performed correctly, and its wear was minimal.
Basics functioning
In the process of the transmission element most wear on the joints, which occurs under load extension links.As a result, a step chain is increased and it can not perform its functions.Typically, the service life of the element does not exceed 3-4 thousand kilometers that is not more than 1-2 seasons.Wear a bicycle chain is checked for its prolongation.If postponing of the leading stars tooth exposed by more than half, it must be replaced.Repairing this item pointless: after the installation of the chain will be executed on the bike, it will continue to fly, and you can not enjoy the trip.If this element is properly take care, it will last much longer and reduce your costs.
principles of work
important to figure out how to pull the chain on the bike properly when first installed, otherwise find difficulty moving bike and will break the mechanism of transmission.To do this, perform the following steps:
- bicycle wheel is turned up and is mounted on a solid foundation;
- measured the required length of chain - leave enough margin of 5-10 mm, which is compensated by a roller;
- all the stars and other elements of the transmission are lubricated to reduce friction;
- circuit is disconnected on a special link - lock, which snaps easily and opened by means of the tool, and then easily return to its original position;
- first put on the biggest stars from the back, then the front;
- circular rotation of the crank and bottom bracket shell around the axis of the chain assembly put into working position (spring-loaded mechanism gear tensioner provide her the required position when changing speeds).
If you follow this simple method of theses, you will not have difficulties with the transmission.All the accumulated experience in the installation process can be applied to teach friends how to pull the chain on a bicycle.
Maintenance
While walking in inclement weather on the elements of the transmission accumulated water and dirt, and if you do not service these components and systems immediately after returning home, a natural abrasive and rust quickly withdraw them from the system.Corrosion - this is an inevitable consequence of neglect of the chain, its sworn enemy.Too intensive care is also contraindicated - grease (grease) binds the particles of dirt and dust, which leads to accelerated abrasion stars and consequential damage.
Adjust the chain on a bicycle
In order to establish the necessary tension, the bike flipped and placed on the seat or rack mounting.The rear wheel is removed by loosening the screws or loosening the eccentric clamp.Lowered brake lever and bracket on the wings, so as not to interfere with the work.Further, the circuit is disconnected by means of the lock, remove the excess part of her, and after shortening it returns to the place.
If your bike is an old design (with horizontal dropouts), all processes are simplified considerably.Suffice it to move further along the guide wheel and the question of how to put the chain on the bike properly resolved.However, in this case it is necessary to control the deterioration of records, as ignoring them could lead to damage to the stars.
Cleaning and maintenance of chain
Preventive measures to minimize the wear of the transmission must be carried out regularly.To do this, remove contaminated chain and flush it with solvent.There are special devices that can help in this process and to preserve the purity of your hands.
They are called "slops": they are a box with special brushes, rollers and guides, filled with fluid, which washes away dirt particles.If such a procedure carried out on a regular basis, then the problem is how to pull the chain on a bicycle, will not bother you, and part with the success will last several seasons.
If cleaning is carried out for a long time, the rust is formed, which is much harder to remove.Chain must be immersed in a container of corrosion or kerosene converter (best used air as it fewest impurities) and stand for several days.Next, it must be removed, clean with a wire brush and leave to dry in the sun.After a while, every link must be of a special grease nipples and install the operating position.How to pull the chain on a bicycle, we have already discussed earlier in this article, so the complexities of this issue will not arise.It is important to follow the logic, and your intuition.
features and special cases
Despite the fact that many bicycle chains fitted with a special removable link, some of them, this time not by design.It may confound the novice mechanic - Ports item is not any desire, and how to pull the chain on a bicycle - is unclear.In reality, the issue is simple: rivet link from any distracting thin steel rod or special Clutch release device.Works are carried out in the following order:
- 2 rivets are removed from management;
- removed once the link;
- circuit is connected and installed so that the closed end of the lock plate located along its rotation;
- open part securely fastened rivet.
Now you are ready to self-maintenance drive your bike.
