What Is The Purpose Of A Bike Chain?

Your bike moves ahead by transmitting energy from the pedals towards the vehicle wheels through a bike chain.

The chain of a bicycle is made up of several steel parts. This contains many sets of internal and exterior plates fastened together by fasteners. While pressing the fasteners across both exterior plates, a wheel divides every pair of interior plates. The internal plates and rollers allow the rivet to pivot freely.

The bicycle chain’s responsibility is to provide force and power through the pedaling to ensure a comfortable ride. Sadly, the power decreases as the bike becomes more supple. As a result, pedaling will need significantly more effort, making riding practically impossible.

Derailleur chains, as well as single-gear chains, are now the two different categories of bicycle chains.

Derailleur: How To Tighten A Bike Chain? Summarize

Turn the bicycle over and put it onto a platform before you begin to adjust the chains on a gear wheel bicycle. The chain may be made tighter by releasing the back wheel and afterward pulling back upon that back tire. Re-tighten the rear tire after ensuring the chain is not excessively tight or slack.

Locate the derailleur nut after standing the vehicle up or turning it on its side. By rotating the nut clockwise, you may tighten the chains. Removing the braking from the wire and tightening the derailleur are the next steps in rear tire adjustment. Before beginning your ride, reassemble it all and check the tightness.

Derailleur: How To Tighten A Bike Chain? In Stages

1. Set The Bicycle Properly

Positioning your bike appropriately for watching is the initial step. You can flip your bike upside down, which is the most straightforward and fastest move. That will make it simpler for you to find the derailleur and get to the wheels.

2. Find Where The Derailleur Nut Is

Finding the derailleur nut must be simple now that your bicycle is in the proper position. The derailleur, made up of gears and screws, has a complicated-looking design.

Usually, a “B” is etched next to the bolt but behind the derailleur. You can rapidly tighten your bike chain with this nut. To raise chain pressure, turn it around in a clockwise manner.

3. Get To The Back Tire

One must gain access to the back tire to tighten the derailleur chain. To begin with, you must cut the braking cable connection. You may then access the rear tire by lifting the brake pedal.

4. Modify The Back Tire

One could now modify the back tire because you have accessibility towards it. To tighten the derailleur chain, tighten the tire axle. The bicycle chain will now remain taut as you pedal so that you can depend on it.

However, be careful not to over-tighten the derailleur chain as this might disrupt your pedaling.

5. Assemble Everything Once More

Putting things back together now and testing your bicycle is the final piece. Once more, tightening your screws will ensure proper chain strain. Attach the brakes. Check whether the wheels contact the chains or frame by spinning them once.

You’ve correctly adjusted the chain on your bicycle if neither of them is touching. Last but not least, you may test everything out by riding the bike!

Single Gear: How To Tighten A Bike Chain?

1. Prepare Your Bike

We strongly advise using a bike rack or turning your bicycle inverted to reach the components if you have never performed it previously or are unfamiliar with doing it.

2. Relax The Back Axle

You’ll have to unbolt the axle bolts securing the tires to the bicycle to finish the task. Righty tighty, lefty loosey, shall we say. Therefore, use the ratchet wrench to spin the nuts counterclockwise to make them accessible.

3. Reverse The Back Wheel

By doing this, you’ll be able to tighten the chain up more. You must pull the back tire until the desired chain tension is reached. You should continually monitor the tightness while you draw back to reach the appropriate tightness.

4. Verify That Your Tension Is Appropriate

You’ll see how the strain upon that bike chain changes whenever the wheel is drawn back.

5. Reinstall The Rear Tire

Rear tire installation is complete after you are confident that the chain pressure, mainly on the bike, is correct. Reinstall the missing bolts on the vehicle wheels.

6. Check It Out!

Before embarking on a journey, you should test the system once you have everything in position.

Should The Bike Chain Must Be As Tight As Possible?

We want to feel roughly a half-inch of motion on either side when you adjust a bicycle chain. On the other hand, if you discover that the chain pressure remains too lax, it might be because the cable has grown. The linkages may lengthen with time, which is a potential outcome.

Eliminating certain links should resolve the issue, and the tension would be just correct. Repair the bike chain only if it cannot be readily tightened using the preceding instructions. In contrast, you must replace your chains if it is worn out and loose.


You may now remount and take pleasure in biking’s liberty. Never forget to maintain the chain on your bicycle. You shouldn’t need to retighten it frequently if you wash and lubricate it once a season. To prevent a chain from falling off or creating a crisis deep on a trail, attempt to check the tension of your chain regularly.
