(4 Reasons) Why My Bike Chain Won’t Go Backwards?

A bike chain is made up of a series of metal links that fit together. The links are held together by rivets, and the chain passes over sprockets on the bike’s wheels. The chain is under a lot of tension and can be very difficult to remove. There are a few reasons why your bike chain may not go backward.

If your bike chain won’t go backwards, it could be because of one of these 4 reasons. Old, obstructions in the chain, stretched chains, worn sprockets, or bent links can all cause the chain to slip and make it difficult to pedal. Inspect your chain and sprockets to see if they need to be replaced.

Why My Bike Chain Won’t Go Backwards?

If you’ve been riding a bike for a while, you’ve probably noticed that your bike chain isn’t going backward. 

There are a few reasons for this, and it’s important to understand why it happens so you can keep your bike in good working order:

  1. The chain is old and has stretched
  2. The sprockets are worn out
  3. Obstructions in the chain
  4. The links are bent

1- The chain is old and has stretched

One of the reasons your bike chain won’t go backward is that the chain is old and has stretched. When a chain stretches, the rivets pop out slightly and the links loosen. This causes the chain to slip and makes pedaling difficult. 

You can tell if your chain is stretched by measuring the distance between the rivets. If the distance is greater than 12.5 mm, your chain should be replaced.

2- The sprockets are worn out

Another reason why your bike chain may not go backward is that the sprockets are worn. The teeth on the sprockets wear over time and eventually become rounded. 

This causes the chain to slip and makes pedaling difficult. You can tell if your sprockets are worn by looking at the teeth. If the teeth are rounded or damaged, the sprockets need to be replaced.

3- Obstructions in the chain

The reason your bike’s chain won’t go backward is that it has obstructions in the chain. For example, debris such as rocks or dirt.

4- The links are bent

The last reason your bike chain may not go backward is that the links are bent. This can happen if the chain is installed incorrectly or if the bike is riding over rough terrain. 

Bent links cause the chain to bind and make pedaling difficult. You can tell if the links are bent by looking at them. If the links are bent, the chain needs to be replaced.

How To Fix a Bike Chain That Won’t Go Backwards?

If your bike chain won’t go backward, there are a few things you can do to fix it. First, check to see if the chain is properly lubricated. If it isn’t, you can try lubricating it with WD-40 or a similar product. If that doesn’t work, you may need to adjust the tension on the chain. 

To do this, first, loosen the bolts that hold the rear wheel in place. Then, use a wrench to turn the adjuster nut until the chain is tight. Finally, retighten the bolts and test the chain to see if it will go backward. If it still won’t go, you may need to replace the chain.

Why Does My Chain Get Stuck When I Pedal Backwards?

One reason your chain may get stuck when you pedal backward is that the chain is not properly tensioned. When the chain is too loose, it can fall off the gears and get caught in the space between the frame and the wheel. To fix this, simply tighten the chain using the adjustment screws on the rear derailleur.

Another reason your chain may get stuck is that the gears are not properly aligned. This can happen if you hit a big bump while riding, or if you try to shift gears while pedaling backward. To fix this, simply realign the gears by hand.

Finally, your chain may get stuck because of dirt or debris that has gotten caught in the chain. This is easy to fix by cleaning the chain with a rag or brush.

Conclusion

If your bike chain won’t go backward, it’s likely because the chain is installed incorrectly. The chain should be installed so that it can go through all the gears, including the smallest gear in the back. 

If the chain is too tight, it will bind in the gears and won’t be able to go backward. To fix this, you’ll need to loosen the chain and try again.

It’s also possible that the problem isn’t with the chain, but with the gears themselves. If the gears are misaligned, the chain won’t be able to engage with them properly and will slip. This can be fixed by adjusting the derailleurs.
