How To Make Your Mountain Bike Lighter Fast

If you want to make your bike lighter then the easiest thing to do would be to just buy a lighter bike. But you probably love your bike and you don’t want a new one. So we will just have to make the one you have lighter.


The fastest way to do this is to change the tires. This really depends on what type of bike you are starting with. If you have a 29er you can immediately take off pounds by changing to a 27.5 inch wheel. You can also get thinner tires which weigh less than thicker ones.

Additionally for your tires you can change the inner tube to latex instead of butyl tubes which are a little heavier. Not only that, you can also just go tubeless


Change the rims to carbon which are the lightest. The lightest of the rims are climbing rims. They are normally on average between 280 grams to 450 grams. They will help you to keep going up hill even when you are tired.

Other Quick Changes

As long as it is still comfortable you can get a lighter seat to sit on. Get lighter handlebars and stem by using carbon fiber. Change the drivetrain to a 1x.

Change the material of the frame. Carbon fiber is the lightest, then titanium, aluminum, then steel. Aluminum is the most commonly used and will save you a lot of weight if you used steel.

Do you really need all those gears. If you have many gears you probably have 3 chain rings which are made of heavy metal. Consider getting a compact crank which will leave you with 2 chain rings and less weight.

Why Are Mountain Bikes So Heavy

  1. First these types of bikes are heavier than other bikes because riders ride them off-road. In order to do this without hurting yourself or your bike larger thicker tires are needed. Riders go over dirt, rocks, roots, grass, water, sticks, and even logs.
  2. Second these all terrain bikes need extra support and stability. Therefore they have more suspension than a road bike. Going over obstacles in your path makes for a bumpy ride so shocks are needed which adds to the weight.
  3. Next in order to handle the bike while riding the fork and the frame need to be sturdy. You do not want either one to break. Even though they can be made from carbon to steel they can’t be too thin or they won’t be able to handle the impact of riding off-road.
  4. Finally, the metal parts of an all terrain bike are heavier and more durable than a road bike’s. These components include the front and rear derailleur, chain rings, the cassette, the disc brakes, and the crank arm.

Is 30lbs Heavy For a Mountain Bike

Overall, the answer to this is no. As long as you feel comfortable on a 30 pound bike you will be able to ride fast with it on flat ground as well as up hills.

If you are racing it could be heavy, but you can always adjust which gear you are in. The weight of this bike may help you because of momentum, as well as keep you stable going over small obstacles. For racing lighter is usually better depending on your bodyweight.

Thirty pounds could be a factor depending on the type of riding you are going to do with it. If you are going to be rough with the bike and go downhill and go over big drops this weight can probably handle it. Though you may be better off with something heavier.

The weight of a bike does not have much effect on how fast you can go. On level ground it takes just as much energy to maintain a top speed on a 30 pound bike as it does a 25 pound bike.

When mountain biking it is more important that the bike is sturdy and handles well in order to get through the trails and paths. Actual skill is the name of the game not so much how heavy or light your bike is.


Now that you know the average weight of various types of mountain bicycles you have a good starting point. It is up to you to know how you will use your bike and then to try out some bikes for yourself. This way you will know whether you should ride a heavier or lighter bike as compared with the average.
