Rusty Bicycle Chain What To Do

Old bike chain slips

She stretched out to a critical level. If you want to be sure. purchase one of the control devices and estimate the degree of elongation:

Rusty Bicycle Chain What To Do

  • Special chain gauge. The meter is simple and convenient.
  • Calipers. In terms of accuracy, this tool is preferable to caliber.
  • Roulette. Most inaccurate fixture.

Replacing the chain and cassettes

When replacing a chain in cyclists, difficulties arise that can be avoided by performing the following algorithm:

When replacing cassettes, use:

  • Key with chain;
  • Adjustable wrench;
  • Retainer ring remover for bike cassettes.

Algorithm for removing the cassette:

  • Take off the wheel;
  • Install a puller so that the spitz falls into the retaining ring;
  • Place the handle of the key with the chain (whip), the case of the cassette, and from the bottom of the chain, on the star, so that its links are tightly installed on its teeth;
  • Put the adjustable wrench on the cassette remover, and return it counterclockwise, holding the whip and preventing the views from scrolling;
  • Unscrew the locking wheel;
  • Remove and unfold the stars and washers in the order that no confusion arises during installation. this is the final stage of removing the cassette.

Algorithm for installing the cassette:

  • There are various grooves and pins with the same size on the sleeve and stars, with the help of which the installation will be in the required order;
  • Lubricate the thread of the retaining ring before installing the cassette;
  • Put on the stars and spacer rings alternately;
  • Some cassette models assume pressing the last asterisk during installation;
  • After installing the last sprocket, screw the retaining rings, check the correct installation of the views, and if correctly installed, tighten the retaining ring with the Cassette Remover until it stops.

Why chain slips on a speed bike 2 reasons and recipe for treatment

Statements such as “I’ve been rolling for the third year, we do NOT service anything, and everything is fine” ultimately lead to serious problems. Slipping tenaciously with power pedaling is one of them. This fact happens more often from ignorance: what and when needs to be changed. Less often, interruptions in the smoothness of the chain are caused by actions that contradict the instructions for setting up SEPARATE components.

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:

  • Extension of the chain due to wear of its links (in particular, their thinning)
  • Sprocket wear;
  • Two reasons at the same time.

“Chain damper

To eliminate the risk of chain falling off the stars, cyclists install a Silencer. They can be equipped with rockring. special parts made of plastic to protect them from impacts while passing obstacles. curbs, pits, etc.

How they are installed ISCG calming agent:

  • Prepare tools: hexagons, squeezers, carriage pullers, thread clamps, keys for removing the bonds and lubricant;
  • Remove the stars and connecting rods so that the large star is set to the middle one;
  • Screw on the rockring;
  • The optimal position of the roller is selected (with a 6-inch suspension travel, the position is strictly at 12 o’clock, with a smaller one. at 11:30)
  • Tighten the bolts;
  • Threaded fasteners drip in the area of ​​the mounting bolts;
  • Install connecting rods;
  • They put the stars on the chain;
  • The rollers are attached;
  • Align the distance between the inner pancake and the star so that it is identical to the distance between the outer pancake and the star;
  • The chain is not required to touch the pancakes;
  • After tightening the bolts all the way.

Sprocket wear

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. Then you need to replace it with a new one.

Caliber

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 the sections 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 will NOT be able to 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 gauge is crawled.
  • The chain needs to be changed. The foot of 0.75% passes freely, and 1% is available.
  • Replacement of the bike and cassette with a set is required. If even 1% moves freely between the links, then it will slip tenaciously, and the teeth of your favorite rear sprockets are already “elongated”.

Attention! The gauge shows the distance between the rollers, not between the axes of the links. The diameters of the rollers in Shimano, SRAM, KMC chains are the same. In Campagnolo it is larger, so the standard gauge does not fit them.

Conclusion

If the size of the chain and the stars are correct during overshoot, then the problem lies in the breakdown of the switches. This usually happens with a recent replacement of parts, and over time it fades. In this case, the inconvenience is temporary. In the second situations, the help of a service specialist may be required.

Stretched chain

The most common cause is chain stretching due to long-term use of the bike, which causes the chain components to wear out. The main indicator of chain wear is its length (normally it is 304.8mm).

As a result, the spring on the derailleur does NOT tension the chain. This contributes to chain sagging and a decrease in the quality of gear shifting (which is especially noticeable when changing from low to high speeds).

It is almost impossible to restore the elasticity of a worn part. After that, there is only one way to solve the situation. replacing the chain.

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:

  • Extension of the chain due to wear of its links (in particular, their thinning)
  • Sprocket wear;
  • Two reasons at the same time.

Measuring chain stretch

Stretching the chain does NOT imply lengthening, it occurs when the links are worn, due to 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:

  • Using a tape measure, 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;
  • Measured distance from 1 to 25 wasps.

Based on the results obtained, they understand how necessary a chain replacement is:

  • 30cm 48mm. new chain condition;
  • 30cm 48mm to 30cm 64mm is 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 the decision to replace parts.

Sprocket wear

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. Then you need to replace it with a new one.

What to do if the bike chain slips?

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? 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 greasing. But even if all the rules for caring for the transmission are observed, its parts will still wear out over time. Then their replacement is required.

“Chain damper

To eliminate the risk of chain falling off the stars, cyclists install a Silencer. They can be equipped with rockring. special parts made of plastic to protect them from impacts while passing obstacles. curbs, pits, etc.

How they are installed ISCG calming agent:

  • Prepare tools: hexagons, squeezers, carriage pullers, threaded clamps, keys for removing bonds and grease;
  • Remove the stars and connecting rods so that the large star is set to the middle one;
  • Screw on the rockring;
  • The optimal position of the roller is selected (with a 6-inch suspension travel, the position is strictly at 12 o’clock, with a smaller one. at 11:30)
  • Tighten the bolts;
  • Threaded fasteners drip in the area of ​​the mounting bolts;

  • Align the distance between the inner pancake and the star so that it is identical to the distance between the outer pancake and the star;
  • The chain is not required to touch the pancakes;
  • After tightening the bolts all the way.

Both factors at the same time

Also, the chain can slip due to the stretched chain and wear of the sprockets at the same time. This pattern is due to the following: as the distance between the chain rollers decreases, the sprocket teeth also narrow. To determine the degree of wear, it is enough to compare the width of new and worn views.

The reason for the one-time wear of the chain and sprockets is also incorrect gear shifting. This leads to a strong distortion of the chain, and some parts of the parts are under increased pressure, and they wear out faster.

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, control the immobility of the wheel to the center of the frame.

Bicycle chain problems

The chain is also subject to wear over time, and if your chain breaks off while driving, it may be stretched and requires replacement. Although things may be much simpler. It may be sufficient to rinse it out of dirt with water, and then lubricate it well

, dripping one drop of oil for each link. A characteristic sign of a poorly lubricated chain in this case can be a squeak when driving, pedals spin poorly and significant efforts are required. Doesn’t rape the bike, just oil the chain.

Then there is such a situation. Personally, I met with a replacement chain.

The chain was stretched and replaced with a new one. So, at that moment, I drove for about a couple of years of intensive riding and of course the chain and sprockets came into a state of slight wear. I replaced the chain, but when I put a new one on, everything was fine, until I got caught in the rain and in very heavy mud. From that moment on, the chain began to slip on the bike. I cleaned the bike pretty well and oiled it well. Although this had never happened before, no matter how mud I rolled, there was no scrolling. Well, so it turns out there is such a need (feature) as “aging of the chain”, ie. The chain was too new for my rear sprocket, and therefore I just need to wait for it (chain) to age for some time. In a simple way, you need to go and wait until the chain is rubbed with an asterisk. In this case, the problem arose only when the bike got into the mud.

Ideally, the entire transmission of the bike should be changed. The transmission in this case is the entire mechanism leading to the movement of the bicycles. stars, chain, cassette (rear set of stars). If the chain is old, then it leads to wear on the stars. If the stars are erased. they will lead to a gradual deterioration of the state of the chain.

Also, chain slip problems can be caused by a jammed link. THOSE. Some link bends not softly enough, roughly speaking, it is bent to one side or at the wrong angle. In this case, you need to drive the link into place or, alternatively, bite it out of the chain.

Bicycle sprocket crank wear

Bicycle sprocket problems can be seen with the naked eye. If you apply too much force to the pedals of the bike while riding, this can lead to a number of problems over time. For example, a bicycle chain is stretched and then you have to change the bicycle chain

READ  Replacing The Rear Wheel On A Bike With Speeds

There may be another option that the sprockets on the bike are erased (lick off over time) and, as a result, poor grip, which leads to pedaling while riding.

It is quite possible that your asterisk is just dirty and it will be enough to just rinse it thoroughly from dirt, and then wipe it with kerosene to remove excess impurities.

If you have a problem with a licked asterisk. So you will first need to remove the rear sprocket, and then disassemble it and possibly replace some parts with new ones, or maybe sharpen the teeth of the sprockets. It is better to give it to a professional for study. in a service center, or even better to replace the drive mechanisms I bought new parts instead of old ones, because how long after repair they most likely will NOT last.

Rear ratchet problems

A malfunctioning ratchet can also be a prerequisite for pedaling. Perhaps too thick oil was poured into the ratchet and the bearings inside the steel stuck. Perhaps there is no oil at all and the mechanism is rusted, it is possible that the lubricant inside is mixed with dust and dirt, i.e. The lubrication has become patchy. The ratchet bearings may have fallen off. In this case, remove the bike ratchet, clean it, if necessary, from dirt (until it is completely cleaned), and then grease it with thick oil.

It is imperative to check whether anything needs to be Lubricated at all. When you removed the ratchet, look at the color of the oil, if it is black or so to speak dirty or with an admixture of metal (the bearing flew). in THESE cases, we clean and lubricate. See if all bearings are in place. It so happens that a bearing breaks over time. this must be replaced with a new one. Also, when you look inside the cassette, make sure there is no liquid inside. If there is still liquid, we clean and then lubricate. So to summarize, if you look inside the ratchet (or cassette) and see clean oil, bearings are in place, fluid is present. in this case, do not touch anything. the bicycle chain lubrication and cleaning are simply not needed.

Why can a chain on a bicycle come off. an overview of the causes and their elimination

Thousands of new members are added to the cyclist army every year. Novice owners often do not know what causes the chain on a bicycle to fly off and what to do in such situations. Let’s consider the main causes of the problem.

  • Weak chain tension in bicycles without gears
  • Insufficient chain tension in shifter bikes
  • Damage to SEPARATE bike parts
  • Bicycle sprocket crank wear
  • Bicycle chain problems
  • Rear ratchet problems
  • How to quickly and conveniently clean the chain.
  • Conclusion

Weak chain tension in bicycles without gears

The rear fork of a conventional bicycle, without shifting speeds, under the influence of loads and vibration, changes the position of the shaft along the axis of the rear hub. Chain drive slack increases. A slight push releases the chain from the sprocket teeth. The chain slips off. To fix the problem, you need to follow the steps in sequence:

  • Upside down bike.
  • Loosen tensioning bolts.
  • Will settle the wheel to the required depth.
  • Tighten the bolts hard in the new location.

Cycling will be fun and the chain will not go off anymore if you fit the wheel properly. Correct position implies:

  • Lowering the chain by about 5 mm. the state “in line” makes it difficult to pedal;
  • Here the rear wheel hub should be perpendicular to the plane of the frame. Otherwise, the risk of deformation of the rim increases;

To improve the grip of the nuts, use lock washers.

If in the extreme position of the sprocket critical slack is NOT eliminated, you need to rivet the links to reduce the chain length.

Insufficient chain tension in shifter bikes

Often the reason why the chain flies on a high-speed bike lies in the failure of the compensating springs to perform the functions to prevent sagging. Occurs when the spring is loose or the chain is stretched. If the test shows excessive chain elongation, you need to remove the extra links. A weakened spring cannot be repaired, you will have to change the rear gearshift block.

Adjustable by bolts with indexes “H” or “L”.

  • The chain does NOT fly off the rear wheel cassette if the derailleur sprockets are in the same plane as the largest or smallest sprocket in the cassette. Bolt “H” changes the alignment with the smallest, and bolt “L” with the largest diameter stars.
  • For the front wheel, bolts “H” or “L” set the gap between the teeth of the stars and the walls of the front derailleur frame equal to one millimeter. A knob with the letter “L” sets the gap between the largest star and the inner wall of the frame, and with the letter “H”. between the smallest star and the outer side of the limiter.

You need to carry out the action with the gearshift unit with the setting on the shifter of the speed mode corresponding to the selected star.

Damage to SEPARATE bike parts

Sometimes the chain on a bicycle flies off when the teeth are deformed from a blow or fall. In such cases, it is very difficult to return the teeth to their previous position on their own. Depending on the mounting of the stars on the cassette, a separate damaged star or the entire block changes.

Violation of the geometry of the bike frame or wheel (figure eight) can lead to imbalance and slipping of the chain from the star.

The cause of the breakdown is a change in the direction of the carriage and bushing axes. As a result, the chain links do not fit tightly enough to the teeth of the sprocket and easily jump off. An additional negative manifestation of deformation of SEPARATE parts of the bicycle is accelerated wear of moving parts.

A minor figure eight can be corrected at home by loosening or tightening the knitting needles. Riding with a warped wheel is possible, but you should remember that a rock or pothole increases the figure eight and the chance that the chain will come off on the bike. It is best to contact the Repair Shop, where they will explain to you why the chain on the bike flies and solve the problem with the breakdown.

Bicycle pedals spin or chain flies

  • Articles:
  • You have worn out drive sprocket or rear sprocket
  • You have problems with your bike chain
  • You have problems with the rear wheel hub, ratchet
  • Find out also what pedals can be put on the bike and why you need it

Conclusion

Now you know how to fix bike chain wear with your own hands. With the replacement of the necessary functional elements and the correct adjustment of the switches, the bike will ride like new again, pleases its owner with excellent speed and transmission on any part of the route.

The details of any mobile mechanisms, during their service, have properties, they wear out and becomes unusable for work. On a bicycle, these parts include: front, rear sprockets (cassette), bicycle chain and other mechanisms. Each unit in any technique requires proper care, this makes the parts work out their resource and contributes to reliability and long service.

But still, how NOT to care for a bicycle chain, there comes a time when it starts to slip, time and load gives its own. In such cases, do not pull to replace the chain, as this may damage the sprockets on the cassette and pedals.

First of all, make sure that the front and rear derailleur settings are correct. First of all, you need to Pay attention to the hit of the chain on the sprockets and DO NOT lie between them. If the bike is not fast and has no derailleurs, then the first cause of chain slippage is loosening. In this case, it is necessary to tighten it.

If the switches are set correctly, and the circuit begins to slip under load, there are several reasons for this:

  • The chain is severely stretched
  • Front sprocket wear
  • Worn cassette sprockets
  • Or all of the above at once

Since when cycling, the chain inevitably stretches over time, the chain links no longer fit correctly on the teeth of the front and rear sprockets, and begin to wear them over time. The wear of the stars also occurs from contamination of the mechanisms with dust and dirt, therefore the chain must be periodically washed and lubricated. Read about how to do this in the article.

What to do if the chain starts to slip on the bike?

If, nevertheless, if your bike is already starting to overshoot syndromes, then you need to prepare to replace the chain and sprockets. Get ready immediately to replace the chain and cassette, as the already stretched chain

It could easily damage its teeth, it may also be necessary to change the chainrings, it is necessary to watch their wear.

In some cases, you can postpone the purchase of stars. It is necessary to look carefully at the teeth, as a rule, it happens that cyclists prefer to ride at several speeds, while others only use NOT a lot of time. After looking at wear, try NOT to switch to the speed at which the maximum output is, Use other stars. But this is still not a long way out of the situation, it is better to replace the necessary element, and boldly ride, Do not forget to service it, clean it, Lubricate it on time.

Consider a common mistake made by beginner cycling enthusiasts. chain skew due to incorrect gear selection. In this situation, not only the chain, but also the front and rear sprockets, wear out strongly. The rule of gear shifting must be observed. For example, if the chain is on the front largest sprocket, then on the back you need to choose small ones. 1, 2, 3 stars.

For example, it is not worth driving uphill in heavy gears (large sprocket in front, small ones in the rear), since the load also strongly affects the stretching of the chain and wear of the sprockets, and besides, it is easier to change the correct gear and calmly continue driving with ease.

Check regularly that the gear derailleurs are set correctly, as they can also cause chain distortion and wear on the sprockets.

What to do if the chain is off the bike

Imagine this situation. you are riding, drove away quite far from your home and here “bryms”, a bicycle chain flies. The problem is not the worst, but if you have never put the chain back in place before, difficulties may arise. It is especially unpleasant that cyclists usually do not have any tools with them.

This article is planned as a short Emergency Guide to be used in the field. And also, below we post. So that you can quickly solve this problem.

First, be prepared to get your hands dirty with oil. As they write on modern memes: “You can’t just take and put the chain in place, and not get your hands dirty”.

Secondly, problems begin not just when the chain is off the bike, but when the chain gets stuck between the system and the frame. This is the worst case. But let’s take everything in order.

First, let’s figure out why the bicycle chain flies at all?

There are several reasons:

  • Strong shaking while driving
  • Too stretched chain
  • The chain was recently oiled
  • Switch incorrectly configured
  • One of the chain links is biting, not turning
  • Sprocket is bent or cassette is damaged

Most often we deal with a combination of factors at once.

The most unpleasant situation, when the chain falls into the space between the frame and the star, occurs if at one of the moments the chain is “in an advantageous” position for this. All Factors Described May Play.

The principle of a light bulb in the mouth works here. it fails in one direction, but does NOT get back. But, unlike a light bulb, the situation can be corrected without the help of a traumatologist.

Depending on the type of bike you are using, there are two different options, which depend on the type of transmission.

So, what to do if the chain fell off?

  • If the bike is fast and the chain does not fall between the system and the frame, simply place the chain over the desired sprocket with your hands, bending the derailleur foot. Step the pedals and enjoy the ride.
  • If the bike has one speed and the chain is tensioned by moving the rear wheel in the fork, then the situation is a little more complicated. Turning the bike over and scrolling the carriage with the system. We try to hook the chain off with the tooth of the chainring. If it starts to engage, then gently help the chain to slide into place with your hands and do not forget to rotate the cranks at the same time. As a help, you can use a screwdriver or an ordinary stick.
  • If the chain falls into the space between the frame and the system, then you are in the most unpleasant situation. You need to try to catch the position in which the chain fell into this space. Of course, if you have a squeeze or a connecting rod puller with you, then the situation can be simplified. But usually they are not. Therefore, you need to try to push the chain back. The chain itself needs to be rotated in different planes and look for an advantageous angle. Sometimes you have to help the chains come out, hooking it with a star and cranking it through the frame. It is best not to do this, because you are forming a notch on the aluminum frame, and it may crack at this point. This option can be used only if the situation is completely hopeless.

Try to help yourself with various objects. sticks, screwdrivers, etc. The star can be slightly bent (by 1-2 mm) using a lever (just do not overdo it, otherwise the whole system will need to be changed).

  • Similarly, the situation is solved in the hit of the chain between the cassette and the spokes (if suddenly the protection is not installed).

Remember! The most important thing here is patience. The situation seems insoluble only at first glance. After a long search for an advantageous position, the chain will surely jump out of this dead position, and you can put it back on. Most importantly, DO NOT make it worse J DO NOT use excessive force and do everything carefully.
