Parts of Mountain Bikes You Need To Know

A mountain bike comes with a number of parts, which can be assembled into one complete bike. As a mountain bike rider, it is important you know about these parts.

That great information and knowledge about the parts can come truly handy if you need to replace something about your bike.

Here are some basic parts of the mountain bike if you are planning on assembling one.


This forms an integral part of the mountain bike. It is the core, a skeleton of a mountain bike. This part plays a key role. It actually holds all other parts of the bike together. When you are shopping for your bike’s frame, you are always advised to pick the right size that matches your height and also one that can give you a very comfortable ride.

This part also comes made from different materials and each comes with its own share of features.

Some of the most commonly used materials include carbon fiber, alloy, steel, aluminum, and titanium. Titanium despite coming with a huge price tag, is probably the best of them all. It is incredibly strong, but interestingly lightweight.


If you once in a while hit one of the roughest areas out of town, the great suspension is all you need. What this feature does is that it helps reduce the shocks and vibrations, especially when you are riding in rough terrains.

We have two types of suspension; front and dual suspension. When it comes to the front suspension, as the name suggests, this one comes with a set of shock absorbers only on the front wheel. On the other hand, with dual or full suspension, you have the shock absorbers installed in both the front and rear sections. This is the most suitable option for technical terrains.

Most mountain bikes that come equipped with a full suspension system often feature a very complicated frame than those that come with front suspension


This connects together the handlebars and steering tube of the fork.  Normally measured in millimeters, the stem plays a key role as it is the part that determines the actual distance of your reach to the handlebars and also your position. The longer this part are, the more stretched out there you would be.


Located right at the front part of the bike, this is where you usually place your hands. It is used to steer or even maneuver the bike. This part also comes in a number of styles and shapes. This is aimed at meeting the specific needs of any rider. Other than just helping you steer the bike, the handlebar also holds the brake lever, derailleur shifter, headlight and also a cycling computer attachment.

When it comes to deciding what handlebar to go for, as a rule, if you are looking for great comfort, the wider, the more control and leverage you get. However, this will come with a few sacrifices. With a wider handlebar, the response time in making turns can be a little bit slower and also difficult.


This plays an integral part when we talk of how rotatable the front and the frame are. A number of headsets we have in the market usually come with two cups that are pressed right into the top and bottom of the head tube.


This is basically where you put your two-foot on. This part helps creates a sort of cycled motion and it is what helps make the bike move forward. When it comes to this part of the bike, the choice you make is essential. It is important you choose the right pedal as that will make you a better rider. It also gives you greater control over your bike, ensuring you are safe when you are riding your bike at all times. We have four types of pedals; basic platform pedals, advanced platform pedals toe clips and clipless.


Brakes system is another important component that makes up part of the mountain bike. Brakes’ key purpose is to stop the bike. Apart from that, we could also use this part to do a number of things like regulating the speed and controlling the bike when you want to perform any advanced technique.

There are two basic forms of brakes available today; disc and rim brakes. You can choose to go for each one of them depending on what you want. However, disc brakes are the most preferred choice by most riders. They come with great stopping power and are able to handle any situation with so much ease. They are quite heavy though.


This is a kind of a rod that holds the cranks and the pedals together


This sits right in between the wheels. The hub forms an integral part of the wheel. It holds the spokes that are attached to the rim. This part also holds 2 machined metal flanges.


These are those wires that join the hub to the rim. They provide the much needed strength and support to the rider’s weight on the wheel. The spokes also plays another crucial role. They actually transfer the power you generate when you pedaling from the hub to the wheel.


This is that one circular metal that the tire is attached to. It holds the spokes and the tire inside and outside respectively. It comes mainly made of metal and butted to form a hoop. This part usually comes in different sizes ranging from 26 to 29inches in diameter. This part does come with a few benefits to the rider. It makes sure you have a smooth and safe ride. It can effectively withhold jumps and bumps among other things.


We have two types; front and rear derailleur,

  • Front derailleur: This is basically to regulate the speed of pedaling when you are riding. The front derailleur is used to shift the chainrings.

  • Rear derailleur: Unlike the front derailleur, the rear derailleur helps shift the cassette from one to the other.

Derailleur Shifters:

This basically controls the front and rear derailleurs; and as its name suggests, it allows for shifting of the gear from low to high speed and also vice versa, especially when you are dealing with varied terrains. From a distance you would easily mistake the shifter from brake levers. They look strikingly similar and are located next to the handle grips.


This is where you sit on, and the type of saddle your bike comes with will determine how comfortable that ride is going to be. Those, not well-designed saddles can lead to a lot of pain on the road. However, while well-padded saddles come highly recommended, at times that cannot mean more comfort. Normally, the level of comfort you net from this part will largely depend on how you adjust your seat properly.

Seat Post:

This is what holds the saddle in place and allows you to make a few adjustments. It slides right into the seat tubes and you can actually move it up or down, depending on your height. One of the best things about this part is that it comes designed to withstand any kind of abuse.

Brake levers:

This is a sort of mechanical or hydraulic mechanism which is often used to transmit the force you apply to the brakes. They often come mounted right on the handlebars and can easily be reached by the rider.


The cranks hold the chin rings and chain; very crucial parts that make the mountain bike move


Located right at the rear wheel of your mountain bike, a mountain bike usually comes with around 5 to 9 stacks of sprocket which you can use to shift. This will allow you pedal with ease especially when you are handling those steep terrains. It also allows you move faster when you are on a flat surface.


These are the circular set of links. They come with amazing benefits. They actually help transfer the power from the chain string right to the cassette.


Tires are the most obvious part of a mountain bike. These are those circular rubber parts that come in direct contact with the ground. Mountain bike tires can be wider and that makes them offer much-needed traction and stability when you are riding.

We have seen tube tires used for years, but things have changed; just like cars, we now have tubeless tires. So when it comes to selecting which tires to use on your mountain bike, some few things will come into play; traction, weight and also durability. You need to factor in these three things before you put your money on any type or tires.


So if you have been wondering about different parts that form your mountain bike, you now have it.
