Chain Slipping on Bike: Common Reasons

Bike Chain Slipping: Why It Happens and How to Fix It

When your bike chain skips or slips, this is when you attempt to change gears once, but due to a malfunction, it ends up changing twice. It is easy to identify as there is a clicking sound.

It is a mechanical problem, and it happens more often than you think. It is an issue that happens to most bikes, but it’s less common when you use a quality bike. In case you want a bike that’s known for its quality and also its durability, you should check out the best road bikes under $3000.

Most times, when riders are pedaling too hard, they may be thinking they’re solely making their bikes go faster, but rather, they’ll end up with a chain slip bike.

There are different reasons why the chain on your bike keeps slipping, and here are a few of the most common ones

Loose cables

One of the most popular reasons you’ll see your bike chain gears slipping is the presence of loose cables. The cables become loose when your bike’s cables aren’t installed properly or correctly tightened to the bike.  You can find loose cables on bikes that you’ve been using for a while, and it can lead to your chains skipping. If you notice loose cables on your bike, you should tighten them.

Worn chain

This is another reason why your bike chain keeps slipping. It is most common in old bikes, and if you notice skipping, it is one of the first things you should check. With time, and use, chains start stretching, and this will lead to damage. If you’re suffering from a worn-out chain and looking to replace it, one of the best options for you to change to is the Shimano XT/Ultegra CN-HG701 11-Speed Chain.

Worn cassette

If your chain is slipping, one of the reasons may be that your bike cassette is worn out, and you may need to replace it. In this case, a new chain won’t help.

So, you’re left with the option of replacing both of them. It is better to avoid it and always keep an eye on cassettes, checking them regularly. They should always be maintained. If you end up replacing the two, a good chain to pair with a new cassette system is the SRAM GX Eagle 12-Speed Chain. It is a very reliable option that will last a long.

Unaligned derailleur

An unaligned derailleur occurs when bikes fall over, and the derailleurs are shifted forward, which bends the hanger. This leads to other parts of the bike being affected, including the chains. When your bike isn’t in use, it should be hung or parked correctly, and this is the best way to avoid having issues with the derailleur.

Filthy sprockets

Another reason why your chain keeps slipping is because of the dirt that piles up around the sprockets. Trusted Source Sprocket - Wikipedia A sprocket, sprocket-wheel or chainwheel is a profiled wheel with teeth that mesh with a chain, track or other perforated or indented material. en.wikipedia.org The dirt can be found in the front, back, or throughout all the sprocket holes. When the dirt gets into the gaps of the sprockets, friction is created between both of the parts, and this causes your chains to skip. You should also clean your chain when cleaning the sprockets.

Incompatible parts

This is a rare occurrence, but it still happens. There are moments when the chain is not correctly attached, leading to the chain damaging and even skipping.  If you’re using a chain that’s not the appropriate size, it is bound to happen.

Damaged parts

If there are damaged parts on your bike, you’ll have issues with your chain, and it’ll eventually slip. Almost all of the components on a bike are connected, and if one part has problems, it’ll eventually affect other parts of the bike.

You must notice faulty parts on your bike as soon as they happen so you can easily replace them to prevent other parts, such as the chain, from damage. If they’re beyond repair, you should look at changing them, and if you need help identifying good quality bikes, you should check out our list of the best road bikes under $500.

Other possible reasons

  • Adjustment issues;
  • Lack of lubrication;
  • Damaged or overused cogs;
  • Worn-out shifting cables;
  • Bad or old shifters.

How to Fix Chain Slipping on Bike

Now that you know the reasons, you may wonder how to fix a slipped bike chain with gears. Well, here are step-by-step instructions for solving this problem.

  1. The first step to fixing chain slipping is to park your bike and turn the pedals until the derailleur has been adjusted to the tiniest clog. Once this is done, you’ll need to check the shifter. If you press it and nothing happens, you must apply more tension.
  2. After this, you must adjust the barrel to the final place by twisting it completely. In case you don’t know where to find the adjuster, it can be located at the back of the derailleur.
  3. Next, recheck the shifter and check whether it’ll move to the smallest hole on the cassette.
  4. If, after all of this, you still can’t shift gears properly, you’re meant to analyze the cables. If they’re too loose, you’ll add more tension, but if it’s too tight, you reduce them.
  5. Then, you’re meant to place the cable in the correct position manually. You should adjust it to the point where the cables can leave the derailleur. After you remove it, you tighten it and then gauge the tension until you can toggle between gears without any skipping.

Following these steps will allow you to fix a slipping chain quickly, but if you can’t do it yourself or still having problems with it, then you should contact a bicycle technician Trusted Source Bicycle Mechanic Occupation Bicycle mechanics or bicycle technicians service and repair bicycles.

Tips on How to Prevent Chain Slipping

A slipping bike chain can cause real damage to your bike and be dangerous for you. Here are some tips that will prevent your bike chain from slipping.

  • Always adjust the tension on your cables.
  • It’s essential that you always align and position both the front and back derailleurs correctly.
  • Ensure that your sprockets are always clean.
  • If they’re broken shifters, replace them.
  • Add lubricants to the rusty areas but ensure they aren’t too much.
  • Make sure always to check whether the chain is compatible with the other parts.

How Do I Know Whether My Bike Chain Is too Loose?

When riding your bike, your chain can become loose, but do you know when this happens? Different signs will notify you that your chain is too loose. Some of them include the following:

1. The chain is stretched

One of the easiest ways to know whether your bike chain is loose is by checking it to see whether it is overstretched. This happens over time, and you can check it using a chain checker. There are different ways to check for stretched chains Trusted Source When to Replace a Worn Chain | Park Tool This article covers the various tools and methods for determining when to replace a bicycle chain so you can extend the life of your components. www.parktool.com , including measuring with a ruler.

2. It constantly falls off

Another sign that your chain is too loose is when it constantly falls off. Typically, your chain is meant to be firm and stay in one place, but if it is always falling off, it is a sign that it’s loose.

3. It appears to be dropping

If you look at your bike and notice that the chain seems to be dropping, it’s a clear sign that it is loose. If you notice this, you should immediately look at tightening it.

Final Thoughts

If you ever notice your bike chain slipping, the best option for you is to fix it as soon as possible. Remember that one problem on your bike can lead to the whole bike being damaged, and buying a new one will cost more than fixing the problem. It is also dangerous to use a bike that has a slipping chain. To avoid accidents or any damage, you should make it a priority to maintain a bike chain regularly.
