Cycling is a great way to exercise and improve your cardiovascular health. However, if your chain falls off your bike, you may not be able to ride as safely. Chain fall can be dangerous not just because it can because you to fall, but it can also cause your bike to become uncontrollable.
One common issue cyclists face is their chains falling off while they pedal. There can be many reasons why this might happen, but oftentimes it is due to wear and tear on the chain or the connection between the chain and cassette. In order to prevent this from happening, make sure to keep your chain in good condition and make sure the connection between it and your cassette is tight. If you experience this issue recurring, do not hesitate to get in touch with a professional bike mechanic for assistance.
Adjustment of the rear derailleur
Nearly all contemporary bicycles have materials prone to breakage installed in the rear derailleur hangers.
You risk bending or misaligning the hanger for your rear derailleur if you ride over a large bump or pedal while exerting much effort. This can happen when you ride over a bump. If the rear derailleur is broken or misaligned, which can occur with a loss of tension in the shifting cables, the chain may slip and fall off the sprockets.
You can correct a derailleur hanger bent incorrectly by straightening it out. You will need a small collection of tools that are not overly expensive to do this work. Please ensure you are confident in using these resources before doing it yourself. In addition, if you are not secure, then in this scenario, taking the hanger to a bike shop to get it serviced might be a wise decision.
Check the rear wheel to confirm that the derailleur on the back of your bike is set up correctly and that it is working properly. Careful inspection is required to ascertain whether the alignment is accurate.
The derailleur, connected to the shifter cable, can be positioned correctly by rotating the nut in either the clockwise or counterclockwise direction. As a direct consequence of this, the pulley oscillates in height. It would help to turn the nut until the pulley is in the correct position.
If an alignment issue cannot be fixed by bending or tweaking, it may be a sign that the rear derailleur needs to be replaced.
Front derailleur positioning
A front derailleur body placed incorrectly on your bicycle may cause a problem with your shifting chain.
Most individuals would rather pay skilled technicians to adjust their automobiles than attempt to do it themselves. The following methods can be used to double-check the measurements and ensure that the front derailleur of your bicycle is set up correctly.
The two most common problems are the front derailleur’s limited screw adjustment and the derailleur’s unintentional height.
Place the derailleur’s outermost arm directly over the ring furthest from the hub. Ideally, the chainring and derailleur’s outer cage would be as near together as possible without actually touching (approximately 2 mm). Numerous sources recommend using a coin of moderate thickness as a measurement unit.
To adjust the position of the front derailleur, you will need to detach the mounting bolt first. This bolt, situated on the opposite side of the seat tube, secures the derailleur to the bicycle’s frame.
It is possible that loosening the derailleur cable will also improve its performance.
After unlocking the derailleur, set it so that the outermost chain ring is at the correct distance from the rear wheel.
Worn Out Cogs
Used gears, which have been used before, may have worn out over time, another possible cause of the slipping chain on your brand-new bicycle. Regardless of how carefully you take care of your bicycle, the chainring and chain cassettes will wear down over time and need to be replaced at some point.
In addition to this, it is essential to check and see that the cogs on the chairing have not become too worn. This is because sprockets that have been used for a long time and are worn out can quickly ruin chains that have only been recently attached.
It is usual for a cassette to have a couple of worn teeth, but if you observe more than that, you should replace the cassette as soon as possible to prevent further damage to your chain.
Changing out the chainring is a simple and speedy process that takes a few minutes to complete.
On the other hand, to successfully do the task, you could want a chain whip in addition to a cassette tool. Remember to acquire the appropriate standard for the chain ring you will be installing. Please consult the owner’s manual for your device for further assistance.
Cleaning Sprockets
The accumulation of filth on the chain ring and sprockets makes shifting gears more of a chore and hastens the wear and tear that would otherwise occur over time.
Ensure that the new bike chain fits appropriately; checking the sprockets for signs of dirt or oil buildup is essential.
Furthermore, it would be a waste if you discarded a chain ring when the problem might have been fixed by cleaning it. The filth on the chain ring may be easily scrubbed off with some degreaser and an old toothbrush.
Once the cassette has been removed from the wheel, it should be placed in a basin containing a degreaser and given adequate time to soak. Don’t worry about it; allow a few minutes to sort itself out. Use the toothbrush to scrub the sprockets until they are scorched, then remove any remaining grime with a paper towel. Remember to re-oil it before you replace it in its original location.
Regular cleaning with a rug or pipe cleaners can sometimes reduce the need for this work.
Change Shifting Cables
The accumulation of filth on the chain ring and sprockets makes shifting gears more of a hassle, and it causes them to wear out more quickly than they would otherwise.
Ensure that the new bike chain can be put without any problems. The sprockets should not have any dirt or grease buildup. If cleaning the chain ring was the solution to the issue, then getting rid of it would be a waste of time and money.
It is possible that the filth that has built on the chain ring can be removed with some degreaser and an old toothbrush.
After being removed from the wheel, the cassette needs to be cleaned thoroughly by being immersed in a degreaser for an adequate amount of time. Just give it some time, and I’m sure things will sort themselves out. Use the toothbrush to provide the sprockets with a good cleaning, and after that, wipe them down with a paper towel to remove any residue that may have been left behind. It is important to remember to re-oil it before putting it back in its original spot.
Keeping a rug in the area or utilizing pipe cleaners regularly are two simple ways to reduce the frequency you need to perform this chore.
Consider Investing in a New Shifter
The chain may skip gears if you utilize old or low-quality shifters due to the loose shifting wires. When the shifters are employed, this occurs.
When paddling through unstable terrain, the shifters could have been damaged. Without functioning shifters, the chain can slip gears, causing the bike to shift into a gear it was not expecting.
Verify that the New Chain is Compatible
It’s possible that the new chain won’t function properly with the other drivetrain parts if you don’t carefully read the manufacturer’s instructions before installing it.
Under those circumstances, there is a chance that the chain will slip and the gears won’t engage properly, to name just two potential issues.
It is crucial to confirm that the new and old components of the bike are compatible with one another, following the criteria established in this field before purchasing one.
Modern bicycle drivetrains are renowned for being intricate and challenging to understand. Without a thorough understanding of component compatibility and interchangeability, it is easy to make some common errors of inexperienced mechanics if you attempt to replace components on your own. One of the most common instances is the directed chains seen on a range of Shimano and SRAM drivetrains from the current age. In other words, there is only one way to attach the chain to the drivetrain to guarantee that the links will mesh with the cogs and rings as planned.
If your bike has this type of drivetrain, doing this will undoubtedly cause the chain to slip while you are riding it, or at the very least, it will cause excessive drivetrain noise and less-than-ideal shifting.
Length of the Chain
Another element that may impact a gear’s efficacy and efficiency is the length of the chain.
The old chain may slip, and the new chain may fall between gears if the new one is too long for the old one. If the chain is too short, it might harm both the transmission and the rear derailleur.
A new bike chain typically has 116 links, which is likely too many for most bicycles.
It can be easier to handle by just taking out a couple of the chain’s links.
You might use an old chain to measure how much shorter your new bike chain has to be.
The chain should be attached to the largest sprocket at the back and the largest chain ring up front (without putting it through the rear derailleur).
It is crucial to ensure the chain is tensioned correctly and to leave an extra inch or link for the derailleur. Once you are done performing this, the new chain will be the proper length.
Avoid Too Much Lubrication
An excessive amount of lubrication will prevent the teeth of the sprocket from making contacting with the chain, reducing the frequency with which the chain slips. Because of this, the sprockets and chain rings get very sloppy, which prevents the chain from properly gripping them.
An excessive amount of lubrication can cause the chainrings and chain to absorb an excessive amount of dirt and dust, which will shorten the lifespan of both components.
If you have applied too much grease to the chain, you will need to give it and the whole drivetrain a good cleaning. When re-greasing, you should only use a small amount of lubricant.
Gear indexing issues
One of the most frequent reasons for a skipping chain is a drivetrain that only needs a simple indexing change. Due to the problem’s pervasive nature, many brand-new bicycles may also exhibit these symptoms.
The good news is that this is likely the most straightforward issue to identify and fix out of all those that can develop. Most of the time, all that has needed to get everything working properly again is a simple barrel adjuster turn, a cable tension reset, and re-indexing of the gears in line with the manufacturer’s instructions.
Worn chains
On older bikes or bikes that have seen much use, the chain is often one of the first items that should be checked if skipping. Check the chain tension if your chain is jumping.
Chains must frequently be changed to keep the drivetrain in the best possible condition because of the natural stretching that happens with use.
A unique tool called a chain checker can determine whether your chain is stretched, and if it is, you should replace it. If it does not fix the problem and you have already ruled out the previously mentioned potential causes, then show the bike to an expert.
Worn cassettes
If the chain has been stretched beyond where it can withstand the strain and is worn out from repeated use, it may be too late to repair it on your own. If your chain has been frequently used after the point at which replacement is indicated, then it is likely that you will need to replace not only the chain but the cassette as well.
Since the cassette cogs will have worn and broken beyond repair with a brand-new chain, it will not be possible to reuse the tape because it will no longer be playable. Because at that point, it will no longer be feasible to undo the damage that has been done.
When the bicycle is subjected to strain, it is common for the rider to place a brand-new chain onto an extremely outdated one inadvertently. This can lead to the dreaded skipping chain syndrome.
Final Words
Even the thought of identifying the problem’s root cause and coming up with a remedy on your own could make you feel worn out. However, the reason for your brand-new bike chain skipping gears or shifting more than once is typically not highly complicated.
You may quickly identify the underlying issues once you have personally examined each component, noted whether or not it is appropriately aligned, and searched for any evidence of damage.
The simple methods and techniques outlined in the essay will make fixing the issue quite simple.
At the least, you should attempt adjusting the tightness of the shifting cable and derailleur before you go and replace any components.
