Is It Necessary To Have A Bike Chain Guard On Your Bike?

It is often still debated whether you should invest in the chain guard. In many competitive situations, weight is what people try to limit and ensure that they don’t waste too much weight on some of these guards. However, there are some benefits that you could find when choosing a guard for your bike chain:

  • Prevents Dirt From Entering: One of the first things you will notice is that less dirt tends to get onto the chain. This could prevent rust and ensure that you don’t need to deal with any damages when riding the bike.
  • Prevents Snagging: Nothing can be more frustrating than having your trousers or shoelaces caught up in the chain. The bike chain guard will prevent this from happening.

  • Adds Something New: If you want your bike to stand out when compared to the competition, it should stand out when you use the chain guard.

If you are a professional rider, these issues might not occur, which means you might not need a chain guard. However, having one can make a huge difference to ensure that you have protection and some peace of mind.

3. Setting Up The Chain Guard

Once you have the old guard removed, you might need to consider adding the new one. To start, we would recommend that you wash the chain thoroughly to remove as much of the dirt as possible. This is also the optimal time for you to check the chain and see if any potential damages or issues could haunt you.

To install the new bike chain guard, you will need to see how it mounts. Generally, three different connections need to be made. You will need to make sure that you first connect the guard around the chainrings. Secondly, you will be moving to the chain, which means that you will be spending time connecting it to the chain of your bike.

Once all of this is completed, you will need to make adjustments to the guard to ensure that it operates smoothly. It could take you some time, but eventually, you will be ready to add the finishing touches.

4. Finishing Up

Once you are done, you will need to add some lubricant to the chain and ensure that the chain is on the pegs. Once the chain is ready, you can spin the rear wheel to make sure that nothing is impeding the chain and how it moves. You can add some lubricant and the bike should be ready for your next trip.


The bike chain guard is one of the fundamental additions to bikes that have to endure tough conditions and the outdoors. Using these guards might not improve your performance, but it could reduce the breakdowns you are dealing with.
