How Does a Suspension Fork Work?

A bike is not complete without a suspension fork. How Does a Suspension Fork Work? If you are a mountain bike rider, you can ascertain that. What do you think makes a mountain bike’s wheels move up and down and at the same time maintaining contact with the ground for shock absorption? 

Well, all that is the work of the suspension fork. You can ride faster with the help of the suspension fork. The experience of riding a suspension mountain bike with a suspension fork is rewarding. Although this component is expensive in terms of purchasing and installation, most bike riders are willing to put in the price. 

Components Of A Suspension Fork

A bike usually has a rear and a front suspension fork system just as the bike has a front and rear wheel. Both systems have two key elements that make it functional. The two elements are what people refer to as shock absorbers since they simply absorb shock from the tires.


Trust me, you might know where the suspension forks are situated on your bike but you spot it every time you use the bike. It’s just that you don’t know the basics of the suspension fork. The spring is one of the suspension system elements. It is usually a steel coil just like ordinary springs, only that it is strong. It can also be in the form of a cylinder with pressurized air. 

Now with the idea of the spring, you can easily spot the suspension fork. When the bike’s wheels come to a bump, the suspension will move up. Once the wheel passes the bump, the suspension moves down. This makes the wheels seem like they are moving up and down. This is possible with the help of the spring. 


The spring will not work alone. It needs the damper’s help. When the springs make the suspension to move up and down, it stores some energy. This energy can make the suspension bounce out of control. This is where the damper comes in. 

The damper will simply dissipate the stored energy to prevent bouncing out of control. It is a piston that pumps oil through a tiny hole. The energy in the form of oil will be converted to heat. The spring and the damping rate will be adjustable to make the shock absorption more effective. 

How Does a Suspension Fork Work?

With the concept of the spring and damper components, you can now easily understand how the overall suspension system works. A bike will have a rear and a front suspension fork. Well, let’s see how both work.

Rear Suspension

The rear suspension is the rear shock in simpler terms. Rear suspension will work mostly with the rear wheel of the bike. Rear wheel’s tire will stay in contact with the ground and at the same time the wheel soaks up the impact with the help of the rear suspension.

With that, the rider will have much control and less fatigue when riding the bike. Rear shock is situated at the bikes’ mainframe triangle. The rear suspension’s spring will be larger than the front one. The rear suspension features vary in terms of spring system, adjustments, and travel. 

Different suspension models have different adjustments of the spring rate and damping. Depending on the brand. The rear suspension spring system will be in the form of a steel oil or cylinder with pressurized air. There will also be a variation according to how much the suspension compresses and how much the wheel travels. 

Front Suspension

This front suspension is what is simply referred to as the suspension fork. A bike’s front suspension will work similarly with a motorcycle’s suspension. The suspension fork’s bottom spot will fit at the part that connects the suspension fork to the frame which is a tube. When the when comes to a bump, the suspension moves up compressing the spring, and the damper in form of a piston forces the oil through a tiny hole or the orifice. 


You need to have the best suspension fork ideas if you have a bike. Knowing how a suspension fork works is important. It’s time to have great control over your ride for less fatigue with a suspension fork.
