Disc brakes are heavier than many other types of brakes. They make it easier to ride on rugged terrain. Also, the disc is used at the top of the tire’s axle to make it stop.

It increases the weight of the MTB. The dropper seat post also adds extra weight to the mountain bikes. It allows the riders to adjust their saddle immediately while they are out on the trail.

The components of the mountain bikes are thicker, stronger, and more significant. The wheel spokes, disc brakes, tires, suspension, and dropper Seatpost are built to handle heavy riding. So, the heaviness of mountain bikes should not be not a cause of worry.

Top 5 Contributor To Mountain Bike Weight

The material used to produce the frame and wheels of a bike are the two major factors contributing to a mountain bike’s overall weight. However, there are other components as well that are responsible for the overall weight of a mountain bike.

Wheels: Wheels account for almost 34% of the total weight of a mountain bike. They add the most weight to them and also provide support. However, bikers should ensure that wheels hold their form to operate smoothly.

Fork: Fork seconds the list of contributors when it comes to the weight of your mountain bike. The suspension fork on the front is believed to add 15% of the total weight. It doesn’t include the handlebar and the stem.

Frame: People who think frames add the most weight are of the wrong notion. Frames generally don’t play a significant role when it comes to the weight of a mountain bike. Frames account for just 11% of the bike’s total weight, and other parts play a significant role in determining the average weight of a mountain bike.

Weight Comparison- Full Suspension Vs. Hardtail Mountain Bike

With a variety of bikes available in the market, the new buyers are spoilt for choice. Many people are at a debate to determine whether they should buy a full suspension bike or a hardtail mountain bike.

There is a drastic difference between these two bikes.

However, several people choose the bike according to their weight. So, let us compare the weight of the full-suspension bike and hardtail mountain bikes.

The hardtail bikes are lighter than their full-suspension counterparts. People who need to do a lot of climbing and cover a long distance prefer more lightweight bikes.

A full-suspension bike has a front shock, a rear shock, and a suspension fork up. On the other hand, a hardtail bike only has a suspension fork. The absence of these features makes a hardtail bike lighter.

The full suspension bike may burn a hole into the pocket of the customer. However, most of the full-suspension frames are at least a pound heavier than their hardtail counterparts.

What’s A Good Weight For A Mountain Bike?

A perfectly weighted mountain bike should be such that it helps the rider get the stability, but it should not be too heavy. A mountain bike that weighs somewhere around 24 to 28 pounds would be perfect, and it will be light yet, it’ll provide stability.

This weight considers several things like a hardtail, downhill, full suspension, cross country, and 29er.

Parts of the bike like the front wheel, rear wheel, frame, and fork weigh the most. These four components alone take 60% of the total weight. You can change any one of these four components to make your mountain bike lighter or heavier.

However, the problem is that we are only talking about the average weight of a mountain bike. To completely answer this particular question- what is the right weight of the mountain bike- we will give some examples of various kinds of mountain bikes in the next part.

How To Make Your Mountain Bike Lighter?

Generally, the heaviness of mountain bikes is commendable. However, it seems pointless to carry around empty weight. Reduction of unnecessary weight comes in handy. Let us find out a few ways to lighten up the mountain bikes.

Use Silicone Grips- Silicone grips weigh much lesser than lock-on grips. However, they do an impressive job at dampening the trail buzz. The riders should not glue them on. On the contrary, they should ease them on after cleaning the bar. A little alcohol makes the process easier.

Cut The Steerer- The fork steerer that is too long weighs down the riders. The riders need to decide whether they are comfortable. Then, they could hack off the rest of the steerer.

They could remove the brake caliper, take out the fork and hack off the end with a saw.

Reduce Clutter- The hoses of the disc brakes are always too long. So, it is a good idea to trim and clean the bars. Believe it or not, the length of the hose is almost always present.

The riders need to unscrew the hose and pull off the lever housing where the cable joins. They could also trim and bleed the cabling of the dropper post. Light mounts that are too old and indicator windows from the shifter pods may also be removed to reduce clutter.


As far as the weight of a mountain bike is considered, there is no definite answer. The selection of frames and the components used are responsible for adding the weight.

A butted Chromoly frame is lighter than the one which has straight gauge tubing. In the same way, steel bikes are heavier than aluminum ones.

Moreover, carbon bikes are much lighter than steel and aluminum bikes. Keep in mind that the wheel and the frame are the two major components that add the mist weight to a bike.

Also, the new upgrades that bikers add to their bikes make it bulky, but at the same time, they make it a better one. Such bikes not only feel great to ride but are safe as well.

However, it is not possible to determine the performance of a bike alone by its weight. If you want to know how well a bike climbs and its performance downhill, then make sure to take a test drive.
