How often and with what means it is necessary to wash the chain?
Experts recommend carrying out this procedure after each trip through contaminated areas. The fact is that if you systematically leave particles of clay, sand or earth on the chain, very soon it will begin to rust and fail.
If we talk about what exactly to wash the chain, then there are many options. Some people use ordinary detergents and soap for this purpose, but then the chain must be thoroughly dried, otherwise it will quickly rust. You can also clean the chain with white spirit or kerosene. It is undesirable to use gasoline for these purposes. As a last resort, you can clean the dried-up dirt with a dry cloth or brush. it’s better than leaving the chain dirty anyway.
How to properly lubricate your bike chain: tips and tricks
One of the most important parts of your bike is your bike chain. Its serviceability directly affects the ease and speed of the bike, so every bike enthusiast should very carefully monitor the condition of this element and keep it clean.

The fact is that with systematic contamination of the chain, you will very quickly overtake the wear of the sprockets or the whole cassette and other serious troubles. An unkempt chain will quickly deteriorate, and its replacement. the process is quite complicated, and most importantly expensive.
Of course, if you are fond of short walks in a metropolis, then the problem of chain pollution is irrelevant for you. And it is necessary to wipe it from time to time. Quite another matter. Cyclists who prefer extreme off-road riding. After each such trip, a significant layer of dirt adheres to the chain, which must be removed.
How to properly lubricate a bicycle chain?
It is very important not only to regularly clean the chain from dirt, but also to lubricate it with a special agent. Bicycle chain lubricants are ideal for these purposes. If you carry out this process systematically, you will significantly extend the life of this component.
In order to lubricate the chain, we only need three things:
- Clean dry cloth
- Chain lubricator
Experienced cyclists who have not lubricated the chain for the first time know many secrets that greatly simplify this process:

Having examined your bike, you can make sure that it is not completely rusted, even if it has been lying on the balcony all winter without any shelter. For example, the frame is most likely intact.
Why?. Because it is painted, and a special anticorrosive agent is most likely added to the paint. Most often they rust:
- iron parts of the pedals;
- steering wheel;
- unpainted steering column;
- iron parts of wheels;
- knitting needles.
Important! The frame can also rust if the coating is broken.
Preparation of materials and tools
- metal brush or scraper;

How to remove rust from a bicycle
A bicycle, like any vehicle, needs care. If you are not good enough with him, at the right time he may present some unpleasant surprise. However, surprises can await you even at the moment when you are just starting to prepare for the cycling season. For example, you decided to look at the condition of your two-wheeled friend, brought it from the balcony into the room and found that the steering wheel and iron parts of the pedals were covered with a reddish coating.

Important! True, it is better to refrain from using inorganic acids in this case. They, of course, will save the bike from rust, but they themselves very readily interact with iron, especially nitric acid.
Sulfuric and hydrochloric acids can be used, but very weak solutions must be prepared. In addition, work with these substances should be done with gloves and respirators.
How to clean a rusted dirty bike chain. 4 different ways!
The bike needs to be washed
Although the baking soda solution has neutralized the acid, the bike needs to be thoroughly washed. There is nothing unusual about this, wash it as you always do, only more thoroughly. Conveniently dampen a paper towel with water and rub thoroughly all the areas where you rubbed with acid.
Multiple Ways to Deal with Rust on Bicycle Parts
Several tools and methods help to remove traces of corrosion from bicycle parts and assemblies.
How to remove rust from a bike
Experienced cyclists know that anything can happen to a faithful horse. For example, metal and vehicle parts will rust. In some cases, this happens if the bike:
- caught in the pouring rain and would not be properly dried after;
- poorly tolerated wintering in a damp room or on a balcony;
- was poorly wiped after washing and left for a long time (washed before winter storage, for example).
However, you should not be upset, in most cases such a problem is fixable. There are several effective ways. And the choice of any one depends on a number of factors:
- the objective state of rusted parts (the degree of rust penetration);
- the presence of this or that means for cleaning “here and now”. that is, at hand, if you need it urgently;
- amount of free time.
However, for true cyclists, the last two points are of no fundamental importance.
An effective way to deal with rust is the acidic method of removing it. According to experts, it is he who is able to eliminate the deepest corrosive lesions.
Required for cleaning activities:
The sequence of actions is as follows:
- First, you should prepare bicycle parts and units for processing: clean them of dirt, dust. Then degrease and dry well.
- Acid is poured onto the abrasive material (!) And not onto the surfaces to be treated. over, it is applied so that citrus juice does not drip, and the pressed metal shavings are simply moistened.
- Sanding material moistened with lemon or lime juice should mechanically remove rust from the affected areas. You need to clean everything. the rims, the chain (only then it is from this part that acid residues must be removed very carefully. every last drop), spokes, etc. Clean the sprockets with extreme care.
- For subsequent washing, the bike is turned upside down.
- Actually, this is followed by flushing. It is necessary so that the acid does not corrode the metal in the future. The acid residues are washed off with water. Clean rags are well moistened and all cleaned surfaces are thoroughly treated with it.
- After cleaning, the bike needs to be thoroughly dried. Wipe it dry (several times) with a clean cotton rag.
For added effectiveness, table salt can be added to lemon juice. Better. large for also abrasive impact.
You will need to lay a strong film under the bike and you can get to work:
- clean the treated surfaces from possible dirt and dust;
- degrease the parts and assemblies to be processed;
- dry surfaces well;
- apply the transforming composition with a thinner layer, spraying from a can (if equipped with a spray bottle) or using a regular sponge;
- wait for the time indicated on the packaging of the product;
- remove the composition using a clean cotton rag or napkin.
If the first time it was not possible to remove the rust completely, it is necessary to repeat the full processing cycle. until the traces of corrosion are completely removed from the cleaned bicycle parts and assemblies. If complete cleaning is impossible, some other, more effective method should be used.
Bicycle parts most susceptible to rust
Those who believe that the first bicycle frame to rust in adverse conditions is very much mistaken. Most likely, it will never suffer, since it is covered with a special paint spraying with a high degree of protection against such troubles. But the steering wheel, rims, front fork, metal parts of the pedals, bolts, arches under the saddle, etc yes, there is corrosion here, where to roam.
In any case, to start dealing with damage, it is necessary to clearly determine which parts were really damaged. Assess the degree of rust penetration and select a method for dealing with corrosion damage. And at the end of the cleaning measures, make sure. that absolutely all parts requiring cleaning are in perfect condition.
There is another (quite often used) way of getting rid of bicycle parts from deep (and not so) rust. The method is quite interesting and, importantly, really effective.
- small zinc piece;
- longer wire;
- soldering acid;
- dry clean rags;
- a piece of cotton wool;
- one self-tapping screw;
- light bulb (12V);
- protective gloves.
Cleaning work is carried out in stages:
- Zinc will need to be wrapped first with cotton wool, and then wrapped in a clean rag.
- Self-tapping screw is screwed into zinc, through layers of cotton wool and rags.
- Next, a simple electrical circuit is created. a wire is connected to the self-tapping screw, which is then connected to the battery through a twelve-volt lamp.
- A piece of zinc is moistened in soldering acid (it is imperative to work with protective gloves);
- Parts and assemblies (previously cleaned of dirt and dust, degreased and dried), affected by corrosion, are processed with a zinc swab. Before the formation of a characteristic gray plaque.
- The tampon is disconnected from the battery, and the cleaned surfaces are washed and dried (very thoroughly).
The “trick” of this original and extremely effective method is that the treated areas will never rust again! And you don’t even need to cover them with some kind of special protective layer.
It is often used as the most accessible tool when there is no caliper or caliber at hand. Using a tape measure, the total length of the first 24 links is measured (from the center of the first pin to the middle of the 25th axis), on the basis of which the conclusion is drawn:
- Up to 304.8 mm. The chain is new.
- 304.8-306.4 mm. You can ride.
- 306.4-307.9. Change.
- than 307.9. Replace chains and cassette.
Why do chain slip through the stars occur?
This is the easiest tool to control. It is calibrated to two sizes in percentage terms: 0.75% and 1%. How to use it? Insert the fixture between a section of several links with one foot, then turn the fixture over and place it in the same way. No matter how you twist it, you can’t make a mistake. Diagnostics makes one of three diagnoses:
- You can ride. The chain is not considered to be stretched if neither side of the tester is slid.
- The chain needs to be changed. The foot of 0.75% passes freely, but 1% does not.
- Replacement of the bike chain and cassette with a set is required. If even 1% moves freely between the links, then the chain will slip, and the teeth of your favorite rear sprockets are already “extended”.
Attention! The gauge shows the distance between the rollers, not between the axes of the links. The roller diameters of Shimano, SRAM, KMC chains are the same. Campagnolo has a larger one, so the standard gauge does not fit them.
Bicycle sprocket crank problems: what to do
Once you’ve identified the source of the problem. the cranks. and figured out the cause, you can start fixing it. The simplest case is sprocket contamination. Just rinse the parts thoroughly, wipe with a dry, lint-free cloth and let dry. Never lubricate parts wet! After thoroughly drying, you can lubricate with special oil. An important point: there should not be too much grease, otherwise it will again lead to malfunctions.
If the sprocket is “lapped”, then it must be removed, disassembled, cleaned of dirt. A worn sprocket may need to be replaced or sharpened. Even if the sprocket on the bike can be repaired, then it will not last long, so it is better to spend money on repairs right away. If you’ve never done anything like this before and are worried about scrolling on your bike, repairing is the best solution.
The main causes of chain slip
The transmission loses ground as soon as you put load on the bike. The problems are pronounced if the cyclist is heading uphill, and the model of the two-wheeled bike does not matter. single speed or high-speed transport. Experts identify several reasons why the chain slips on a bicycle under load:
- links are lengthened due to wear;
- teeth located on the sprockets in front and behind are worn out;
- two parameters at the same time.
The last option is familiar to bike owners who have previously repaired the chain or cassettes separately.
If you create ideal operating conditions for the axles of the links of the bicycle chain, then the components of the chain drive can travel for years. about 10,000 km without any intervention. It is still possible to guarantee the absence of distortions, but it is difficult to ensure surgical cleanliness and the constant presence of grease in the roller-pin contact patch.
For your information. The experience of operating the Shimano chain is about 10,000 km instead of the usual 1,500 km. To achieve this level, after each ride, clean all links with a kerosene-based preparation, such as WD-40, and lubricate with a dust-repellent bicycle lubricant. Well, distortions, of course, are unacceptable.
Transmission wear due to incorrect gear shifting
Not every bicycle owner knows how to use it correctly. skills come with experience, but while it is being developed, the risk of transmission malfunctions increases dramatically. Remember the basic rules:
- When counting the stars at the front, start with the smallest.
- On the rear cassette, the opposite principle works. the counting starts from the largest star.
- When shifting gears, combine the combination of large stars in the front and small ones in the back.
- You may have noticed that there are fewer sprockets on the front cassette. It is easy to conclude that there are several rear sprockets at once per one front sprocket. Consider this moment when changing gears.
Only by learning how to properly shift gears on a bicycle, you can avoid excessive skewing of the snake, which provokes wear and tear of parts at a rapid pace.
What to do if the chain slips under load on the bike?
A bicycle is a complex of parts and moving mechanisms, which tend to wear out and break over time. One of the popular problems is when the chain slips, what to do? It is quite simple to get an answer to this question if you know the design features of a two-wheeled vehicle. It is also important to take into account the type of bike, operating conditions, and support for the technical condition of the device. Thus, you can significantly reduce the wear of all parts, ensure the performance of the bike and a comfortable ride.
Causes of chain problems
Even the simplest bicycle contains a complex of interconnected parts. The precise and uninterrupted functioning of each element ensures the reliability and performance of the equipment. For example, many cycling enthusiasts have a question: the chain slips, what to do? To get an answer, you need to determine and eliminate the causes of such a situation, and for this it is worth knowing the design features of the vehicle.
One of the main parts of the bike is the chain, which is stretched over the sprockets. Due to the rotation of these elements, movement along the track is carried out. In this case, even the simplest systems can fail, that is, the chain will begin to slip. This situation can arise for the following reasons:
- Significant wear of the chain links, which leads to the elongation of this element;
- Due to wear, the teeth of the front and rear sprockets are grinded;
- Too much wear on the cassette stars;
- Simultaneous impact of the above factors.
Long-term and intensive use of a bicycle without maintaining the technical condition, timely replacement of parts and their lubrication inevitably leads to disruptions in the performance of equipment. Most often, the chain slips due to a lack of proper and quality bike maintenance. That is why it is important to properly care for the technical device, performing inspection, lubrication and replacement of parts in a timely and regular manner.
One of the common reasons for the rapid wear of the transmission is incorrect gear shifting. In any case, the sprockets, chain and all parts of the moving mechanism need regular maintenance to keep the bike in good working order. Timely lubrication of elements, replacement and careful operation of equipment allows you to avoid a long time of occurrence of such a situation when the chain jumps on a bicycle under load.
After finding the answer to the question about the cause of the chain malfunction when the bike is loaded, it is worth subjecting the technician to repair. Such an event can be carried out independently, because the main reasons for parts wear and breakdown are known. In this case, all actions should be carried out very carefully, and the old elements must be replaced with new ones with suitable dimensions. Such a careful approach allows you to quickly and efficiently change the necessary system parts and ensure the bike‘s performance under optimal load.
An extended chain can damage the sprockets, and therefore all system components must be replaced. If the problem is detected early, changing the sprockets can be avoided, but it is best to carefully inspect the teeth and determine if there is any damage. You also need to remove the chain from the bike and measure its length. If this parameter is more than 308 mm, then the part should be replaced. Otherwise, the chain will slip on the bike under any load.
With large stretching of the links, the probability of damage to small and medium stars is quite high. Therefore, a thorough examination of these elements is important and allows you to determine the next steps. If the sprockets are worn out, the sprockets of the required size should be selected and the cassette renewed. An alternative option for replacing parts is to install a special “damper”, which allows you to maximize the life of damaged elements. Such a device is often used in cycling and prevents the chain from flying off the stars.
One of the most common causes of circuit problems is inaccurate switch settings. In this case, the bike chain slips under load. In this case, it is necessary to adjust the switches, and for this you need to set a suitable tension for all cables, adjust the travel in the lowest gears and optimize the travel in large sprockets. In this case, the features and characteristics of the technique should be taken into account.
Why does the chain slip on a bicycle
The first symptoms of transmission malfunction occur when shifting gears while depressing the pedals. Cyclists often notice this immediately when going uphill, because then the load on the bike is one of the strongest.
Reasons for chain slippage on a bicycle:
- stretching of the chain due to wear of its links (in particular, their thinning);
- wear of the sprockets;
- two reasons at the same time.
What to do if a chain slips on a bicycle?
Any type of cycling will always have a significant impact on its drivetrain. Why is a chain slipping on a bicycle and how to fix the problem? The chain and stars will wear off or deform over time.
To prolong their life, regular maintenance is recommended in the form of cleaning from dirt and dust, and lubrication. But even if all the rules for caring for the transmission are followed, its parts will still wear out over time. Then their replacement is required.
What to do if the chain slips?
If the chain slips on the bike without gears, it is enough:
- unscrew the nuts in the area of the rear wheel axles;
- pull the wheel towards you;
- tighten the nuts, controlling the immobility of the wheel to the center of the frame.
The stars can deform due to wear or mechanical damage resulting from impact. In both the first and second situations, it is impossible to restore the cassette teeth. Therefore, a replacement with a new one is required.
Measuring chain stretch
Stretching the chain does not imply its lengthening, it occurs when the links are worn, as a result of which the distance between them increases, and the chain wears out. There is some discrepancy in the pitch between the sprockets and the length of the chain link in the worn part. As a result, the cassette and the entire transmission system do not work properly.
To determine the degree of wear, you will need:
- use a tape measure to measure 24 chain segments;
- this can be done without removing the chain from the bike. on the upper tensioned part;
- normally, the length of 24 segments is 30.5 cm;
- the distance from 1 to 25 axis is measured.
Based on the results obtained, they understand how necessary the replacement of the chain is:
- 30cm 48mm. new chain condition;
- from 30cm 48mm to 30cm 64mm. normal length;
- from 30cm 64mm to 30cm 79mm. the length indicating the chain is worn out, replacement is required, otherwise the first problems with the transmission will appear;
- over 30cm 79mm. critical stretching, in such a situation, replacement of both the chain and the cassette (or sprockets) is most often required.
With a stretch of 30.8cm, the ride becomes unbearable. The chain either gets stuck or slips and dangles. Some use a squeeze to shorten the chain by a couple of links, but this does not help to solve the problem for a long time, and as a result, they come to a solution to replace parts.
