What are Rear Shocks and Do You Need them on Mountain Bike?

Mountain Bike

Do you need rear shocks on a mountain bike? That is a question that many people ask, and the answer is not always clear. In this article, we will discuss what rear shocks are, what they do, and whether or not you need them on your mountain bike. We will also provide some tips for choosing the right rear shocks for your bike.

What are Rear Shocks?

Rear shocks are an important part of a mountain bike. They help to absorb the bumps and vibrations from the trail, making for a more comfortable ride. According to Chain Reaction, he shock allows the rear wheel to soak impacts up, rather than being transferred to the frame and rider. This increases comfort and grip on the rear wheel, allowing for better traction. It also helps to protect the frame and rider from damage. The rear frame triangle that holds the rear wheel is connected to the mainframe by way of a shock. The length of the shock and its travel (the distance it can compress) will determine how much the rear wheel can move independently from the frame. This is important because it allows the bike to soak up big bumps and drops, rather than being transferred to the rider. Shocks also have a spring inside them, which is what controls the amount of travel. The stiffer the spring, the less travel the shock will have. So, if you're riding on a lot of rough terrains, you'll want a shock with more travel. Rear shocks also consist of two telescopic tubes that slide into each other. There is also a spring and an eye at both ends which are connected to the frame. The length of the shock and its travel has an impact on how much the rear wheel can move from the frame freely.

Do You Need Rear Shocks on a Mountain Bike?

Rear shocks are important for many reasons. First, they provide comfort by absorbing bumps and vibrations. Second, they improve traction by keeping the tire in contact with the ground. Third, they help the bike to handle better by keeping the rear wheel from bouncing around.

So, do you need rear shocks on a mountain bike?

The answer is, it depends. If you ride on smooth roads or trails, you may not need them. But if you ride on rough terrain, they can make a big difference. According to REI, they will make your ride more comfortable and will help you to keep control of your bike. If you are not sure whether or not you need rear shocks, talk to an expert at your local bike shop. They can help you decide if they are right for you and your riding style.

How to choose a rear shock that is right for you?

If you are looking to upgrade your mountain bike, or if you are buying a new one, you may be wondering if you need a rear shock. The kind of rear shock that will be right for you will be largely determined by two main things. There is Sizing and the Spring type. Both spring type and sizing interrelate to a certain extent. This is specifically in the riding discipline where coil shocks are more prevalent for downhill and air shocks for cross-country.

Coil shocks

Coil shocks are the older technology and tend to be heavier. They're made of a steel spring that's wrapped around a shock absorber. The spring compresses and decompresses to absorb bumps in the trail. Advantages: Coil shocks tend to have better small-bump compliance than air shocks. According to Bike Radar, that means they do a better job of soaking up repeated bumps, like those you might encounter on a washboard section of the trail. They're also less likely to bottom out, meaning they won't compress so much that the metal spring is exposed. Disadvantages: Coil shocks are heavier than air shocks, which can make your bike feel sluggish on longer rides. They're also more difficult to adjust than air shocks.

Air shocks

Air shocks are the newer technology and tend to be lighter. They use pressurized air instead of a steel spring. The air pressure is adjustable, so you can fine-tune the ride to your preference. Advantages: Air shocks are lighter than coil shocks, which makes your bike easier to maneuver on the trail. They're also easier to adjust than coil shocks. You can add or release air pressure to fine-tune the ride to your preference. Disadvantages: Air shocks don't have as much small-bump compliance as coil shocks. That means they don't do as good of a job soaking up repeated bumps. They're also more likely to bottom out, meaning they'll compress so much that the air chamber is exposed.

Replacing rear shocks

When replacing a shock, you need to make sure that it is compatible with your frame. If you are replacing a worn-out shock with the same model, that will not be an issue. If you are upgrading to a newer model, however, make sure that the new shock will fit your frame. A shock is not measured by the amount of the bike's rear travel that is largely determined by the type of suspension design that has been used on your frame. On the contrary, it is measured by the length of the stroke and its eye-to-eye measurement. The eye-to-eye measurement. This is the length of the shock absorber itself from the center of one mounting eye to the center of the other. The stroke length. This is the length by which the shock compresses especially when it's fully loaded. It is not to be confused with the amount of travel that your bike has. For mountain biking, you would need a rear shock that has at least 50mm of travel. Anything less than that and you would be compromising the performance of your bike, especially when riding on rough terrain.


From this discussion, there is no doubt that rear shocks are important for someone with a mountain. They help a lot in riding, especially when the terrain is not good. It is advisable to get a rear shock with a minimum of 50mm travel. This will help you enjoy your mountain bike more.
