When the bicycle chain is old and damaged, what kind of crisis will it run into? Chain dropping may be easy to solve, but it also directly predicts that your chain is quite old. Breaking the chain is an unforeseen and unexpected situation. It is not as easy as Bluetooth Printer to take photos. You must carry the repair tools at any time and reconnect the chains in halfway to restore the original state.

After ending such long-distance riding distance, not only is it consuming its own physical fitness, but also because of long time stepping on heavy teeth or at the same time shifting speed, it also adds muddy and wet riding conditions, causing the chain to get stuck in too much dirt, and on the chain. During the alternation of the lower chain, the wear of the chain is increased and its life is shortened. What are the crises that will be encountered in the old and damaged chains? If you neglect the maintenance chain for a long time, then clean it regularly, oil it, chain will get stuck in the environment because of many dirt after many uses, make the chain lose its function, can not easily transform your top The chain and the chain directly cause the ride to go wrong and there is a kind of kaka feeling.

Everyone knows that if the chain is not properly maintained or used properly, it will soon be damaged. Without the chain, the existence of the bicycle is meaningless. Therefore, the chain must be properly maintained, but how can it be maintained and used correctly?

How To Lube Bike Chain

  • First of all, make sure that the lubricant used is the right chain oil in the chain. Not all lubricants are the best for the bicycle chain. If you do not know how to use the most suitable lubricant, you can ask questions. The master of the car or a professional person.
  • In order to avoid excess oil build-up and blockage, only oil in critical parts of the chain, such as “Roller”, will reduce wear and abnormal noise during operation of the chain.
  • Just use a little lubricant against Chizhou rust in other parts of the chain.
  • When we oil the chain, we can’t do it perfectly. So before we finish we need to wipe off the excess lubricant on the chain surface.
  • In the case of variable-speed vehicles, attention should also be paid to rear-shifting pulleys, gears, and flywheels. Use the same principles to maintain and lubricate these parts.
  • After the bicycle chain is lubricated, use a dry cloth to wipe the excess oil on the chain to prevent dirt and dust from adhering.
  • Be sure to add lubricant to your bicycle chain every time you clean it, wipe it, or clean it with solvent.
  • Before applying the lubricant, make sure your chain is dry. Do not lubricate the chain after it has rained. This is not very effective and the chain is also unfriendly to the lubricant.
  • Lubricate the lubricant through the chain bearing and then allow it to become viscous or dry. This can really lubricate the parts of the chain that are subject to wear.

Questions about chain maintenance

The timing of chain maintenance depends mostly on your riding situation. Humidity and muddy riding environments will, of course, be more frequent than dry and tarmac roads. Below to introduce you to the bicycle chain maintenance time and the correct use of knowledge.

Pay attention to the timing of maintenance:

  1. Reduced transmission performance.
  2. The chain appears tight (the chain snaps into the front chainring).
  3. Noise is generated when the drive train is running.
  4. You can hear the chain rattling when you walk through a tunnel or through an object. (This means the chain is too dry)


When driving on a general road, it needs to be maintained at least once every month or every 150 kilometers (150 miles); when driving on off-road roads,

At least every 100 kilometers (60 miles) should be cleaned and maintained once.

How To Clean A Bike Chain

  • Clean your chain after every ride, especially in rainy and wet conditions.
  • Take care to wipe the chain and its accessories with a dry cloth.
  • If necessary, use an old toothbrush to clean the gap between the chains.
  • Also don’t forget to clean the front derailleur and the rear derailleur.
  • Use a brush to remove dirt and dirt that accumulates between the chains and, if necessary, warm soapy water.
  • Do not use strong acid or strong alkaline cleaners (such as rust remover) because these chemicals can cause damage or even breakage of the chain.
  • Do not use chain cleaners with added solvents to clean the chain. This type of cleaning will definitely damage the chain.
  • Avoid the use of organic solvents such as scouring oil, which not only damages the environment but also removes the oil from the bearing area.
  • Always add lubricant after each cleaning, wiping or chain cleaning with solvent. (It is not recommended to use organic solvents to clean the chain)
  • Make sure your chain is dry before applying the lubricant.
  • Lubricate the lubricant through the chain bearing and then wait until it becomes sticky or dry. This can really lubricate the parts of the chain that are subject to wear.
  • Confirm that you use the right lubricant, you can pour some hands on the test. Good lubricants begin to feel like water (penetration), but after some time they become sticky or dry (permanent lubrication).
  • In order to avoid excess oil build-up and blockage, only oil on critical parts of the chain, such as “roller”. After oiling, it will reduce wear and abnormal sound when the chain is running.
  • Only a few lubricants can be used to prevent rust in other parts of the chain.
  • Wipe off excess lubricant on the surface of the chain.
  • In the case of variable-speed vehicles, attention should also be paid to rear-shifting pulleys, gears, and flywheels. Use the same principles to maintain and lubricate these parts.
  • After applying lubricant, wipe the excess oil on the chain with a dry cloth to avoid dirt and dust adhesion. Before reinstalling the chain, remember to clean the chain connection to ensure that there is no dirt residue. After the chain is cleaned, before the joints are assembled, it is necessary to apply some lubrication to the inside and outside of the shaft Oil.

Usually People Will Ask: How Often To Replace The Bicycle Chain

This is very difficult to answer, when to change the chain, because the degree of wear of the chain is:

  • Usage habits (performance, frequency of shifts, frame centerline).
  • Environment (topography, moisture, dryness, loach, moisture, salt).
  • Rider riding conditions.
  • The degree of maintenance.

How To Reduce The Wear Of  The Chain?

Different treatment methods also have different effects on the life of the chain. If you use KMC wear and high performance products (such as the X and XSL series chains), you can expect better performance.

Preventing unnecessary chain wear.No matter which chain is used, in order to maximize the life of the chain drive system, we offer you some tips:

  • Follow our recommended maintenance procedures.
  • When shifting, try to maintain the perpendicularity between the chain and the flywheel. (For example, do not use the smallest gear with the smallest flywheel, or the largest gear with the largest flywheel and other extreme gears.)
  • Predict road conditions when changing speeds. (For example, when climbing uphill to advance gears to avoid changing gears, excessive force is added to the chain.)
  • Before parking, please change to the smallest tooth plate to avoid shifting when still.

Some riders use two or three chains at the same time and replace them every week (or every 500-700 kilometers for replacement). This is said to reduce wear, especially for the more expensive gear discs and flywheels. This is quite reasonable.



How To Remove A Bike Chain?

Usually people will ask: how often to replace the bicycle chain

Disassembly and assembly of the bicycle chain: When lengthening or shortening the chain, the chain must be dismantled when changing or repairing the flywheel, rear axle, tire change, and washing chain.

Disassemble method: Use a pair of pliers to abut the joint shaft, and the other point of the pliers abuts the head of the U-shaped spring piece, and then forcefully pinch the spring piece out of the groove of the joint shaft, and the spring piece will fall off the chain link. Then use a small screwdriver to pry off the outer section of the chain and the inner chain can be removed.

Assembly method: When assembling, insert the joint shaft into the hole of the chain link, insert the two holes of the joint piece into the joint shaft, insert the joint piece close to the chain link, expose the joint shaft groove, and put the spring piece on the shaft. With a needle-nose pliers, one end against the bottom of the U-shaped spring piece, one against the joint shaft, and forcefully pinch the pliers so that the spring piece enters into the shaft groove of the joint shaft, so that the joint shaft is stuck and cannot come out.

Drop chain installation: When the chain is mounted too loose, or the sprocket flywheel is not on the consent plane, a long chain drop occurs. How to avoid falling chains? The method is to adjust the chain and sprockets. After the chain is dropped, if it is in the state of a half chain cover or a chainless cover, the chain can be hung on the flywheel, and the chain wheel can be rotated counterclockwise so that the chain is completely buckled on the sprocket teeth. If it is a full chain cover, first remove the front chain cover of the full chain cover from the plug board, and then use a screwdriver to cover the edge of the chain cover, and then pull down the chain cover and align the cover opening with the ankle. The chain is then snapped onto the sprocket teeth from below and the sprocket is rotated counterclockwise to bring the chain into the sprocket. If the flywheel is dropped, the chain cover must be removed. When removing the cover, remove the cover plate of the back cover of the chain cover, unscrew the fixing screw with a screwdriver, hold the back cover with both hands, pull it out after forcefully, and then remove the back cover of the chain cover. When the chain is on, first the chain is buckled into the upper teeth of the flywheel, and then the sprocket is rotated counterclockwise until the chain is fully buckled on the flywheel teeth.

Sometimes the chain joint is damaged or lost, and the spring piece on the link head is more likely to be lost, causing the joint piece to fall off without the spring piece blocking, even the whole chain is disengaged and the chain is transferred into the chain cover.

The method of wearing the chain is: first to go slightly longer than the chain cover, a smaller diameter than the chain pin shaft hole a hard wire, from the channel on the front of the chain to the back of the hood, pull the wire out of the head, the other end Into the chain pin hole, the wire is folded into a dead ring to prevent the zipper strip off. Then pull the wire, the chain into the channel on the chain cover, continue to pull the wire, pull the chain out of the rear chain cover, the chain buckle on the flywheel, wire and then from the chain channel through the lower channel, the chain into Down channel. After the chain passes through the lower channel, the wire is folded into a round shape. At the same time, the chain is fastened on the sprocket and the sprocket is rotated counterclockwise. The chain is hung on the sprocket. At the upper end of the sprocket, the other end of the chain is picked up and loaded. In the joint, remove the wire hook from the end of the hook wire, insert the pin of the connector into the hole of the chain link, install the outer sheet, tighten the spring sheet, and the chain is connected.

How To Tighten A Bike Chain?

Method one:

Pulling the distance between the front and rear wheels widened the chain tightly. There are two reasons to drop the chain: one is the loose chain, the other is the deformation of the roulette wheel, and the flywheel is not in a line. This phenomenon is many, and the faster the ride, the more violent the roulette, it is easy to drop the chain.

Method Two:

1. Loosen the rear axle screw.

2. Pull the rear wheel back so that the chain is tight.

3, screw the rear axle can be tightened.

Method 3:

The bike chain is loose because the distance between the center axis and the rear axle is too close, so we must knock down the distance.

Method 4:

The chain is one of the most important parts of a bicycle. The chain connects the bridge between the hub and the sprocket and is the most important thing in the transmission of power. Therefore, many riders will face the problem of loose chains.

There was a problem with the sound of the dental plate and the hub, and the chain felt loose. You can check through the above methods to see if you really have these problems.

When the chain is tight, it is loose, and when it is in a certain position, it is loose. When it is in a certain position, it is normal. This problem is definitely a problem with your tooth plate, and the tooth plate is deformed.

Due to long-term brakes and the like leading to deformation, the quality of the sprocket is not good, change the sprocket, you can try to turn the sprocket to your brake angle to see if the chain will be loose, go to other parts and change back Tight. The only way is to change the sprocket!

There is also a way to loosen the five screws above the crank of your crankshaft, readjust the position of the sprocket, move it a little forward, and tighten the scrotal screws. If this still does not solve the problem, then you can change a new tooth plate!

How To Fix A Bike Chain?

During cycling, accidents often occur. Apart from accidents, they are not as comfortable as those lying on the Floor Chair at home. For example, if the bicycle chain breaks, punctures occur, etc. If you are on the way, how can you solve these problems yourself?

How does the bicycle chain break?

As long as there is a chain hitch and a chain snap, you can pick back the broken chain.

  • Remove the broken chain first: Put the ejector lever on the plug in the chain, and slowly remove the ejector by tightening the chain catcher.
  • Put the chain buckle into the opposite ends of the chain.
  • then put the two ends of the buckle, the broken chain will be connected.

The chain beater is a small tool for disassembling the chain pin and is very useful in the maintenance of the bicycle.The chain drive consists of a screw and a base body. Above the base body there is a rack of the chain and the screw hole of the screw. When the screw is screwed into the screw hole, the pin of the chain can be pushed against the pin of the head.

Today’s chain hoists generally have two chain racks. A rack is far from the screw hole, and there is a very strong cutting board behind. After the chain is hung on the pylon, the chain piece away from the screw hole is supported by the cutting board. This usage can cut and connect the chain. The other rack is closer to the screw hole. When the chain is hung on it, only the chain piece facing the screw hole is supported. This usage is used to adjust the deadlock of the chain.

To cut the chain, hang the chain on the pylon that is far from the screw hole. Fix the chain first with your hand and gently push the chain with the thimble. After ensuring that the thimble accurately and positively resists the pin of the chain, the screw can be smoothly rotated and the pin of the chain can be pushed out. The chain is already disconnected after the pin is top-to-face and is about to be flush with the inside of the outer chain. When you are at the top, you should pay attention to controlling the amount of movement and avoid completely dropping the top of the pin – it is difficult to reinstall the pin that is completely covered. (The easiest

The solution is to use a hammer, hehe). A careful observation of this process reveals that all the chains are supported. The pin is completely pushed out of the first chain and continues to move through the hole of the other chain until the chain can be disassembled. . The situation in adjusting deadlock is different.

The process of connecting the chains is exactly the opposite of the truncated chain. First, the chain is cut off on the chain hitter, just like the one that had just been cut off from the chain beater. The only difference is that this time the protruding pin is facing the ejector pin. Because we want to put it back. Since the chain is broken, we must take the chain. At this time, the posture of the hand is not so simple. The next step is to gently use the thimbles to hold the pin to ensure a smooth and straightened position. After this is ready, the screw can be smoothly rotated and the pin shaft can be pushed back until the pin is exposed on the other side of the chain. The length of the pin on both sides of the chain should be equal, about half a millimeter. The amount of pin protruding must not be too small. If it is too small, reliable assembly of the chain and pin can not be ensured. It is very easy to break the chain at this chain. This chain is reconnected. Check the pin that you just pushed back to see if the reconnected link can flex.

If the link after the link is tight and awkward, we also have a way to deal with it – adjust this deadlock. This kind of inflexible link is called deadlock. Most of the deadlock was formed when the chain was attached—its two outer chains were squeezed too tightly. To adjust the dead knot, hang the chain on the pylon near the screw hole and gently top a pin. Since this rack only supports one side of the chain, after the top is over, the pin shaft moves a little in the chain piece on the top side, and the other chain piece is pushed away by the pin shaft and the dead knot loosens. some. It is important to note that it is a bit more top-notch, and it is necessary to pin out the longer side of the shaft, so that the length of the pin on both sides of the chain will be evenly adjusted. If the exposed portion of the pin at one end is too short, the pin must be topped by a chain so that its outcrop is long enough. At this time, the link will become tight again, so the process of this adjustment may need to be repeated several times to get the desired result. There are still some deadlock situations. The chain does not seem very tight and astringent after it has just been connected. However, after a period of time, it becomes inflexible. For such a deadlock, it may not be serious to clean and lubricate it. According to the circumstances, it is not necessary to adjust; serious adjustment of the problem directly on the line, this deadlock is often due to the gap when the connection is too small, another reason is that the rough transmission makes the chain has been abnormal twist, squeeze effect.

If the chain beater does not adjust the dead-knot function, the deadlock problem can be solved as well. Using a dead knot as the “axis”, bending the chain sideways with the right amount of force can also create a suitable gap between the chain pieces. Naturally, be careful not to change the type of the chain piece (do not need a lot of effort to make changes), if not sure, you can first practice with the waste chain.

Since we are talking about truncating and linking chains, we must talk about the chain slip. Traditionally used bicycles use clasp type snap-knots. This kind of slip-knocking and disassembling is convenient and does not require a chain beater, but sometimes the clasp will be lost. It is also not suitable for the kind of large bending angles of the gears and the variable speed process. May be used in front of the friction. In general multi-speed bicycles, chains with no slip knots are used, so as to avoid the problem of living knots. There are also special special slip knots on the variable speed car. We call it the magic buckle. This kind of thing is produced by both KMC and SRAM. The domestic common is the magic buckle on the Sachs chain.

This magic buckle is composed of two identical parts that can be stuck together. The interface is clever. It does not need to hit the chain when disassembling, it is very convenient. This kind of magic buckle is also easy to distinguish after installation, and the traces of the interface can be seen from the side.

Shimano’s chain has three kinds of pins, called the terminal pin, reinforced connection pin and connection pin. In order to ensure sufficient assembly strength, only the connecting pin is allowed to be knocked out by the chain drive. When connecting the chain, the old pin cannot be used. The reinforced connecting pin for Shimano must be used (this newly installed reinforced connecting pin It cannot be removed anymore, because the holes in the chain have already been expanded. The reinforced connecting pin shaft is reinforced by further expanding the hole in the chain). There are two different sizes of connection pins for Shimano, Silver is relatively short for the 9-speed chain of Shimano, Black is slightly longer for the eight-speed and the 6th, 7th-speed chain such as hg50. This connecting pin shaft is very convenient to use, it has a section of the guide shaft, you can first cut the chain to wear together and then linked to the chain linker. After the connection is completed, the guide pin is exposed on the outside of the chain and it can be pulled off with pliers.

The chain beater is a very useful tool. It can be useful both for daily maintenance and emergency repairs on the road. The riders may wish to prepare a chain beater for themselves. A good chain hitter is exquisitely crafted, the base body is firm and precise, and the ejector pin is accurately located on the axis of the screw shaft, and the screw and the screw hole are precisely matched, the gap is small, and the screw hole is longer. Such a chain-driver screw is not easy to swing, which means that it is not easy to work when working. It is recommended to choose a small size and it is relatively easy to carry; the chain linker in the combination tool is also good, that is, it is not as good as a single tool. The most recommended nature is ParkTool CT-5, weighing only 70 grams, small and exquisite, extraordinary quality.

The maintenance of the chain beater is very simple. If you clean it and lubricate the threaded part, it will serve you faithfully for a long time. Sometimes the ejector pin may be damaged, and most chain beaters can unscrew the bad ejector pin and replace it with a new one (the above-mentioned CT-5 has a special spare ejector pin). When installing a new thimbles it’s packed tight enough.

Finally, attach tips and precautions for maintaining the chain:

There is a state in which the chain is dialed to the smallest wheel of the smallest wheel before the chain is dialed, so that the chain is relatively loose and easy to operate, and it is not easy to “bounce” after being cut off. After the chain is cleaned and refueled, slowly invert the sprocket, and the chain links coming out from the rear should be able to be straightened. If some chain links still maintain a certain angle, it means that it is not smooth and is a deadlock. It should be added. Adjustment. It has been found that damaged links must be replaced in time, and the maintenance of Shimano’s chain recommends strictly distinguishing the three pins and using the connecting pins. Use a chain beater to pay attention to leveling, so that it is not easy to get rid of the thimble. Careful use of the tool not only protects the tool, but also achieves good results. If not, the tool is easily damaged. Damaged tools are more likely to damage the parts. This is a vicious circle. The function of the tool is just like the MOP at home. It keeps the house clean and gives you a comfortable environment. If you are interested in learning about MOP, you can read this article: Best Hurricane Spin Mop And Dust Mop– Recommended Purchase .

How To Replace A Bike Chain

When replacing the chain, the shift is the front inner, the rear top, and the transmission is more convenient to operate in a relaxed state. When removing the chain, one by one pulls out the ampoule pin at the connection chain block, and at the end of the rotation, it is found that there is no bite. The chain is a fragile accessory. People who often ride bikes should be maintained in advance. It is best to have a chain cutter.

  • Remove the old chain. After finding the pin, insert the chain cutters from both sides of the chain and press the shaft against the center of the needle.
  • It is pin off state. Unhook along the chain line. Be careful not to hurt the body.
  • When using the new chain, the length of the chain is basically the same as the old one. It is easier to compare the old and new, and to align the blocks.
  • When there is no old chain and the length is unknown, the front of the chain is outer, and the rear is top. Doing so will increase 2 more.
  • Place the new chain attachment amphule pin by hand and insert it with a chain cutter.
  • The ampoule pin is engraved with a line mark and it is inserted to be visible from the other side.
  • The part of the ampoule pin protruding inwards is inserted into the hole of the chain blade and the knife can be twisted to fold it.
  • Finally, rotate the shaft to check the tension of the chain and the operation of the transmission.
  • The effective way to oil the chain is to inject the oil into the voids in the joint block. Excess grease that is exposed on the outside must be wiped off. Because it will stick dust and other things. Also pay attention to oil, do not stick to the tire. The chain should be in the outer x top state.
  • Special tool for chain replacement.

How To Change A Bike Chain

Place the chain measuring tool with a curved end between the chains, then pull the chain against the chain axis and try to place the other end of the measuring device in the gap in the chain. If you can’t put it in completely, it means that the chain doesn’t need to be replaced. You should pay attention to cleaning chain, roulette, and day

Regular lubrication can be. If the other end can be inserted, the chain stretch distance is too large and it needs to be replaced immediately.

Clean the chain, flywheel and sprocket before replacing to prevent the new chain from getting dirty.

Adjust the bicycle gear to loosen the chain and remove the chain from the upper teeth of the sprocket to prevent the chain tension from being too large to remove the magic buckle.

Find the position of the chain magic buckle, push the two sides of the magic buckle together and remove the magic buckle.

If the chain does not use the magic buckle, you need to use a chain cutter to separate the chain. Hold the chain in the groove of the chain tool to ensure that the chain link is perpendicular to the drive tip and avoid the top hole being worn.

Push the thimble in. Tighten the handle of the chain tool so that the thimble can just top the chain pin. When all thimble passes through the chain, unscrew the ejector pin.

Pull out the chain in the direction of the chain’s rotation during everyday riding.

Compare the lengths of the old and new chains and cut off the extra parts of the new chain.

Re-enter the new chain. At this time, it should be noted that the chains of some brands are designed to be one-way, so when installing, it is necessary to ensure that the brand logo is placed outside the chain.

Make the chain hole straight and insert the pin into the chain.

With a chain cutter, the new pin is snapped into place. The new pin is very easy to start moving. Only when it is the last millimeter, you feel that the pin is fixed.

After the new chain is installed, you need to remove the guided pin. With pliers, quickly twist the larger direction to separate the pin sections.

The first time the ordinary chain just installed will be a bit tight, causing skipping. Therefore, it is necessary to use the thumb to adjust the back and forth on the chain link to ensure the flexibility of the chain when working and shifting gears.
