Converting Mountain Bike to Gravel Grinder

As much as mountain bikes are fun offroad through mountainous terrain, it does not beat the versatility of a gravel bike. So, converting your mountain bike to a gravel bike is a great thing to do. Maybe you've also wondered what the benefits and the differences between them are and if it's worth the hassle?


Converting a mountain bike to a gravel bike instead of buying a new gravel bike is smart and quite simple. You can either do it yourself or ask a professional for help, and it does not cost much. In most cases, it is much cheaper than buying a new gravel bike.

In this article, we'll go over everything you need to know about them and exactly how to do the conversion. But before we go into the modification steps, we'll go over some things you might need to know to help push you actually to go through with the conversion.

Why Convert your Mountain Bike to a Gravel Grinder?

Here are a few reasons why it's great to convert your mountain bike to a gravel bike:

Experience a Better Ride

Unlike mountain bikes, gravel bikes give you the purest experience of a bike ride since they were made to withstand unpaved roads. Moreover, they offer both speed and performance over any offroad terrain.


Nothing is more seasonally versatile, comfortable on all variety of routes, and any terrain than a gravel bike. You can easily take it over from the countryside through dusty or muddy roads to the cities and ride it with ease.

Improve your riding skills

Even though gravel bikes might feel uncomfortable initially, the constant need to sit upright and the bumping vibration will improve your awareness of the tracks and benefit your riding skills. It can also help you even out your pedal strokes and improve bike handling on gravel or offroad terrain.

What are the overall features of a Gravel Bike?

Most gravel bikes are equipped with racks and mudguards; they are safe and convenient for a variety of off-road adventures and events.

It has a more stable frame and fork clearance without the hydraulic disc brakes. Those features make it a bike for all seasons anywhere and much lighter and faster than any mountain bike.

What are the differences between features of a mountain bike vs Gravel Bike?

While mountain bikes have a specific purpose, a gravel bike is more efficient for different riding experiences. The significant differences between a mountain bike and a gravel bike are mostly found with the geometry in design, the frames, braking system, and the tire size.


A gravel bike is taller and has a sleeker design than a mountain bike, which has a shorter frame. Gravel bikes offer better comfort but are harder to manipulate off-road, whereas mountain bikes are responsive for riding down mountain roads.


Mountain bikes are usually made of light metal, such as aluminum and carbon fiber so that they are lighter. Their lightweight build allows it to be easily carried over difficult terrains when riding is difficult or too dangerous. On the other hand, gravel bikes are sturdier and stiffer as they are usually suitable for carrying loads.


Gravel bikes use disc brakes that provide stability and prevents falls on slippery or uneven surfaces. In contrast, mountain bikes usually use cantilever brakes, so it depends on the rims and cannot work independently.

Tire size

Mountain bikes have slim tires, but you can also change them according to your preference. Most mountain bikes have enough room for large tires, but the extra space is usually used for mud clearance, whereas gravel bikes have thicker and a more massive tire for better stability and support.

If you still want to continue with converting the mountain bike into a gravel bike, the features mentioned above are some of the main changes you will have to look into.

To start the transformation, here is a step-by-step guide to turning that bike into an all-purpose bike for the best riding experience.

Steps to Converting a Mountain Bike to a Gravel Grinder

Change the Gear System

Since gravel bikes are much faster than mountain bikes, they require more gearing options than the mountain bikes. So, changing the gear system is an integral part of transforming the bike.

Thankfully, both mountain and gravel bikes use the same 2:1 ratio when it comes to the number of gears. With that said, you will have to increase the number of gears in the mountain bike while still maintaining the ratio so that it does not lose its responsiveness.

Raise the suspension

Once the gears are upgraded, the next step is changing the suspension. The change in suspension is needed for better clearance between the bike and the ground.

And since your mountain bike only has the comfort and features necessary to navigate harsh terrains, you need to make it more versatile by raising the suspension.

Changing the suspension along with the gear is a crucial step to convert your bike into a gravel bike because of the number of obstacles that gravel bikes come across on different routes.

Opt for smaller tires

The third step is to change the tires of the bike from a thicker to a thinner one. Tires play an integral part in making up the difference between a gravel bike and a mountain bike. Most mountain bikes have larger, thicker, and broader wheels designed for rough and winding terrains.

On the contrary, gravel bikes have more agile and thinner wheels to make it light and flexible. So, to convert the mountain bike to a gravel bike, ensure that you install new wheels that are thinner, lightweight, and flexible over different paths.

Change the braking system.

The fourth most crucial part about switching to a gravel grinder is to change the brakes. Since gravel bikes are faster and lighter, you will have to ensure that the brakes have excellent stopping power and are highly responsive. You will also have to switch to a disc brake as it lasts longer and can withstand heavy pressure.

Durable disc brakes are essential when converting to a gravel bike because you will surely use it more frequently over different terrains.

Install a tougher Shock absorber

The next important step is to install a shock absorber that is tougher than the ones on a regular mountain bike.

Most mountain bikes are equipped with robust shock absorber, but while switching to a gravel bike, you will have to make it even more robust as gravel bikes are meant to grind through more challenging surfaces at a higher speed.

Gravel, pebbles, rocks, and dirt come as obstacles where gravel bikes are concerned. So having a high-quality shock absorber is another crucial step in replacing your MTB to a gravel grinder.

Altering the handlebars

Another essential feature you need to change to transform the mountain bike into a gravel bike is changing the handlebars.

Since mountain bikes come with a flat handlebar, they do not perform the same as gravel bikes. To transform it into a gravel grinder, add bar-ends so that you can switch arm and hand position during long rides.

Since you will be riding over different terrains, adding a gel-pad under the handlebars' bar tape will also reduce vibration over rough bumps and pebbles.

Lighten the Weight

Finally, to make your mountain bike match the efficiency and performance of a gravel bike, you have to make it as light as possible.

Whatever materials you use to replace the original parts of the mountain bike should be of the lightest build; however, it should still be made from sturdy materials.

So, while changing the frame may not be an option, replacing the accessories like the handlebar, tires, suspension, and shock-absorber should be possible.

You can also remove all unnecessary equipment and other accessories that will not be handy.
