Why is there so much ado about how much a mountain bike weight?

Does it really matter?

It matters because riders take so much consideration on the weight before they purchase or do an upgrade.

They say less weight, better ride but it is not always the case for mountain trail bikes.

How much does a Mountain Bike Weigh?

Mountain Bikes are definitely heavier than road bikes. They typically weigh around 28 to 32 pounds.

They have additional gears that are needed to conquer the rough and rugged trails. They have substantial brakes for steep uphills and slippery downhills.

There’s also added suspension for the front and rear which adds stability to the ride. 

Different mountain bikes also have varying weight. Beginners would opt for a bike that is durable, weight is not really a huge factor with their first purchase.

Also, a heavier bike gives a more sturdy ride, perfect for those going on their first ride. As you ride more, you begin to discover the type of rider you are- and you begin to associate your usual ride pattern to a particular type of mountain bike.

There’s a specific mountain bike type for a specific rider and weight differs across these types:

​Different types of MTB and their weight

Cross Country MTB

Cross Country Mountain bikes weigh 24 lbs or 10.8 kg. They are the lightest MTB type because on the road they need to go faster and less weight means greater speed.

All-Mountain MTB

All-mountain MTBs, perfect for all types of terrain, weight 30 lbs or 13.6 kg. It has full suspension and has more components than a hardtail contributing to the additional weight. As their name suggests, All- Mountain Bikes are remarkably versatile on any type of trail.

Full-Suspension MTB

Full-Suspension MTBs weighs 31 lbs or 14 kg, the additional weight comes from the shocks and a linkage which helps the bike to roll over obstacles easily.

Full-Suspension MTBS is built for trail riding. There’s a rear suspension in addition to the usual front suspension that enables them to be versatile and agile for the ride.

However, there’s a downside as well. The additional suspension means there’s a need to change the geometrical built of the frame, thus adding weight. (1, 4, 5)

Hardtail MTB

Hardtail MTBs weighs 26- 28 lbs. They are lightweight and simple, perfect for cross country and weekend rides. There’s only front suspension making it lighter than the full-suspension MTBS.

Downhill MTB

Downhill MTBs weigh 35 lbs or 15.8 kg. The additional weight comes from the front suspension and is needed for stability and durability- works well in absorbing the impacts of going downhill.

Downhill mountain bikes can weigh up to 40 lbs. They need to be heavier for the type of rider they are built for- fast and hard ride going downhill that requires stability and protection. (1, 2, 3)

29er MTB

29ers weigh 39 lbs or 17.6kg. It is not a surprise that they are heavier because of their larger tires. 29-inch wheels are two pounds heavier than 27.5 wheels. The additional tire size and weight delivers better traction and improves attack angle.

Currently, manufacturers have learned to tradeoff the wheel’s weight to lessen the additional lbs it adds to the overall weight of the bike by improving the material they use and the geometrical built.

​Conclusion

As you take on more rides, try out more trail and terrain types, you start to understand your own ride.

Understanding your ride pattern would make you consider going for a lighter bike or a heavier one.

There are several things that you need to consider before doing so and it will all depend on how you ride.

Changing the rear and front wheels, the fork and the frame of your MTB will definitely make it lighter because they comprise 60% of the bike’s total weight. (4, 5)

However, unlike the road bikes, going light isn’t always the thing for mountain bikes because road bikes generally roll on smooth road surfaces while MTBs need to do a lot of work on the trails.

The extra weight they have comes from components that equip them to perform well on the terrain.
