Assuming you need to fix the chain on your mountain bike because it has come off:
1. Put the bike in a repair stand if you have one, or flip it over so the drivetrain is accessible.
2. Find the master link. This is the link that hold the two ends of the chain together and can be removed without tools. It will have two pins that need to be presses out in order to detach it.
3. Once the master link is out, the chain should be able to be pulled apart. Put the chain around the cassette (back gears) and front chain ring. 4. Push the ends of the chain together until the master link can be inserted. The master link will only go in one way, so make sure the halves of the link are oriented correctly.
5. Press the pins on the master link in with your fingers or a small tool until they click. You might need to use a chain tool to get the pins started.
6. Test the chain by shifting through the gears. If it feels tight or wonky, make sure the chain is on all the gears correctly.
If your mountain bike chain has come off, you can easily fix it yourself. You will need a chain tool. Most chain tools come with a few spare links, so if you don’t have one, you can buy some at a bike shop.
1. Put the chain back on the ring.
2. Use the chain tool to push out a pin.
3. Put the end of the chain through the gap.
4. Use the chain tool to push the pin back in.
5. Repeat steps 2-4 until the chain is the correct length.

Can you repair a mountain bike chain?
If your bike chain has snapped, it can be fixed relatively easily – providing you have the right tools to hand. We show you how to do it.
If your chain is coming off at the rear, it’s often a simple matter of adjusting the limit screws on your rear derailleur. If the chain is coming off the inside of the cassette, put the chain onto the smaller chainring (at the front) and the largest sprocket (at the rear).
How do you fix a slipped bike chain
Before getting off the bike, downshift bike into lowest front gear (using the left shifter). Being in the lowest front gear means the chain will be riding on the largest chain ring. Continue pedaling. This step alone may realign the chain.
A master link is a great way to reconnect your bike chain. Simply insert half of the master link onto each end of the chain, pull the ends together, assemble the master link and use a master link tool to snap the link into place. It’s possible to link a master link without a tool, but it’s always best to use one to ensure a secure connection.
Can you fix a snapped chain?
A broken bicycle chain doesn’t have to mean the end of your ride. With a little bit of know-how and the right tools, you can often repair it on the road, at least well enough to get you home.
You’ll need a bicycle chain-tool, which is usually included as part of a multi-tool. You’ll also need a spare quick-link. If you don’t have a quick-link, you may be able to improvise with a master-link, but it’s not as reliable.
Once you have your tools, simply remove the broken link and replace it with the quick-link. Make sure the quick-link is properly secured before you ride off.
With a little bit of practice, you’ll be able to fix a broken chain in no time. And with that, you’ll be able to keep on riding no matter what.
There are several reasons why your bike chain might break, but the most common reason is shifting under a heavy load. Shifting puts extra stress on the chain, and if you’re already pedaling hard, it can cause the chain to snap. Even if you’re not pedaling hard, though, just shifting can put stress on the chain. So, if you’re going to be shifting a lot, try to do it before a climb, and then back off the pedaling a bit when you do shift. That way, you’ll avoid putting too much stress on the chain and snapping it.
Why does my bike chain keep popping?
If your bike chain keeps popping off, it could be due to a bent cog spike. However, if the noise is just a loud noise, it is likely due to increased tension on the chain and is nothing to worry about.
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike, your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
One way to fix this is to simply readjust your derailleur. Without getting too technical, each time you shift gears, your derailleur moves the chain a tiny bit. Over time, this can cause the chain to come off track. You’ll know it’s happening if your chain starts skipping, or if it feels like it’s being pulled to one side.
To readjust, start by shifting your bike into the biggest cog in the back and the smallest cog in the front. Then, loosen the screw on the back of the derailleur until there is some play in the chain. Next, pedaling slowly, shift up to the next biggest cog in the back. You should hear the chain clicking into place. If the chain skips or falls off, turn the screw a tiny bit tighter and try again. Repeat until the chain stays in place when you
How do you tighten a bike chain with a derailleur
To adjust a bike derailleur, first shift into a small ring on the cassette. With your thumb, push the body of the derailleur toward the large cog. The top pulley should align with the largest cog in the cassette. If the pulley moves past the largest cog toward the spokes, turn the limit screw marked “L” clockwise to tighten.
The chain on my bike has been slipping when I pedal hard. I think this is because the chain is getting weaker and stretched out over time. The cogs (crank) also wear down over time, which leaves the chain less to “grab” onto. I’m going to replace the chain and see if that solves the problem.
Why does my new bike chain slip?

A dropped chain is the term used to describe the chain falling off the front chain rings (or crank set) on the frame. This leaves you helpless and unable to pedal. In most cases this happens when a derailleur is out of adjustment.
Do all chains have a master link
The master link on your bike chain is the extra-wide link that allows you to disconnect and remove the chain without the use of a chain tool. Not all bikes have these links. They are most likely to be found on BMX bikes, single speed bikes or three-speed town bikes with internal gears. The more sprockets a bicycle has on its rear cassette, the narrower the chain must be and therefore the less room there is for this extra-wide master link.
If your bike chain is starting to feel loose or sticky, it may be time to replace it. Chains don’t last forever, and as they wear out, they can damage your drivetrain.
How much does a bike chain cost to replace? Entry level chains can start off around $15.00 with more expensive and higher performance chains ranging from $25.00 to $60.00 or more. More expensive chains increase shift quality and are generally more durable as they wear.
Not sure if your bike chain needs to be replaced? Bring it in to your local bike shop and they can take a look.
Are all bike chains the same?
There are many different types and sizes of bicycle chains, and not all of them are compatible with all types of bicycles. If you’re not sure what type of chain your bike takes, it’s best to consult your owner’s manual or take it to a local bike shop for help. In general, however, most chains will fall into one of three categories:
1. Standard Chains: Standard chains are the most common type of chain and are compatible with most bicycles. They typically have side plates that are slightly curved, and range in width from 7.1 to 8.9mm.
2. Wide Chains: Wide chains are becoming increasingly popular, especially on mountain bikes. They typically have side plates that are flat or slightly angled, and range in width from 9.0 to 12.0mm.
3. Half-link Chains: Half-link chains are a specialized type of chain that is often used on BMX bikes and some types of mountain bikes. They have side plates that are curved, and range in width from 8.9 to 10.4mm.

How much force does it take to break a chain
According to European ISO standards, a chain must have a minimum breaking force of 8,000 Newtons in order to be considered safe. This is a significantly higher amount of force than what is typically required to break a chain during normal riding conditions. This margin of safety means that broken chains are less likely to occur, making them a thing of the past.
If your chain keeps breaking, it’s most likely because it’s either old and worn out, or it’s the wrong size for your bike.
How do you put a chain on a bike without a chain tool
tools required.
1. Get a new chain.
2. Break the old chain using a chain tool.
3. Connect the new chain using a chain tool.
It is not advisable to reuse a previously pushed out link pin to rejoin the chain. The chain will quickly come apart at that junction when riding.
Why does my bike click when I pedal hard
The chain will rub against the derailleur only in some gears since it changes its angle as you shift gears. That’s why your bike makes a clicking noise when pedaling hard. So, you need to shift your bike into the gear where you hear the clicking.
Livative says 3 things can cause clicking noise when pedaling and riding your bike:
1. DIRTY or DRY bearings
2. An improperly installed bottom bracket
3. Worn out parts
If you’re experiencing any of these sounds, check these areas on your bike:

Why is my derailleur so loud
We’ve all been there: You’re out for a ride on your bike, enjoying the fresh air, when all of a sudden you start to hear a weird noise coming from your bike. It might be a clicking, creaking, or even a grinding noise, and it can be pretty frustrating trying to figure out what’s causing it.
There are a few different things that can cause noise on your bike, and fortunately, most of them are pretty easy to fix. Here’s a look at some of the most common bike noises and how to diagnose and fix them.
1. Clicking, creaking, or grinding noise
There are a few different things that can cause a clicking, creaking, or grinding noise on your bike. One possibility is that a derailleur hanger is bent or out of alignment. This can happen if you crash your bike or if it gets jostled around in transport.
A bent or misaligned derailleur hanger can cause your chain to skip or make a clicking noise when pedaling. You might be able to see if the hanger is bent just by looking at it. If not, you can use a derailleur hanger alignment gauge to check.
To fix
A bike chain which is too loose will affect, among other things, the gears, which will no longer function properly. As a result, the bike chain can slip, come off or even break while riding. The best way to avoid these problems is to keep your bike chain tight and well-lubricated. If your chain starts to slip or come off, you can try adjusting it or lubing it. If your chain breaks, you’ll need to replace it.
Why does my chain go slack when I stop pedaling
If your chain is getting slack on top when you stop pedalling or backpedal, then the problem is in your freehub (or freewheel, whichever you have), a dirty freehub will cause all the problems you’ve listed, even on a brand new bike.
The rule of thumb is that the exact tightness of a chain will only allow you to move the chain about 1/2 an inch. If your chain is too loose, you will need to tighten it. However, if you find that you cannot even move the chain, it is too tight and will need to be loosened.
Final Words
If your chain has come off your mountain bike, there are a few things you can do to fix it. The first thing you need to do is identify where the chain has come off. This can be done by looking at the chain and seeing where it is not connected. Once you have found the spot where the chain has come off, you need to put the chain back on. This can be done by using a chain tool or a pair of needle nose pliers. Once the chain is back on, you need to tighten it. This can be done by using the chain tool or a pair of Vise-Grips.
If your mountain bike chain has come off, don’t worry! It’s actually a pretty easy fix. First, you’ll need to find the rivet that’s holding the chain together. Once you’ve found it, use a chain tool to push the rivet out. Next, reattach the chain to the bike and make sure it’s tight. Finally, use the chain tool to push the rivet back in.
