My Top Picks of Best Mountain Bike Stems
Thomson elite X4
Best Mountain Bike Stem
Now when I tell you this is the very best mountain bike stem, none can ever compare to this.
Not only does this stem ooze quality, it’s solid but light, and the finish is immaculate making it number one on my list.
Thomson started with a vision to make the best most durable stem they possibly can for mountain bikes, making a stem that is significantly sturdier and more lightweight than the competition.
They achieve this mainly by incorporating machined aluminum of 7000 series in making their stem. The stiffness of the stem improves precise control while steering the bike and will blow you away.
But that’s not all.
The material is also rust-free which means washing is not an issue at all and it also means it can tackle any weather condition with no trouble.
The traditional steerer clamp used is designed to save weight and be more knee friendly so you don’t feel massive knee jerks while braking. If you are looking for a stem that is extremely durable, you have come to the right place.

Best Mountain Bike Stem Buyers Guide
Mountain bikes come with all parts but why should you buy a new stem instead of using the one that comes with your bike? What you need to know is that the stem that comes with mountain bikes is not customized.
This means that you are likely to experience some issues related to height, design among other problems. In order to make the mountain bike comfortable, the best thing you should do is to invest in a quality bike stem-like those I have reviewed in this article.
A bike’s stem performs a fundamentally straightforward job, its primary purpose being to ensure the handlebars are securely clamped to the fork steerer.
However, the stem type, materials, and dimensions, length of the stem, and degree of rising play a key role in how a bike fits and handles, so it’s important to choose carefully.
What do I need to look for when buying MTB stems?
Price – MTB stems can cost you a good amount of money. The good ones are pricey but if you look around carefully, you will be surprised at the features you might be able to get at a relatively low price. There is no need to buy super expensive stems as it then becomes a practice in the law of diminishing returns.
Quality – This is of course crucial for stems as they hold the handlebar and frame of the bike together. If the quality is not good, it may break or start slipping which can be a source of accidents. It compromises handling as well. So, be careful when selecting a stem to buy for your MTB.
Clamp – This is, by far, the most crucial part of a stem. It holds the handlebar and fork together. If it slips, it can get you into accidents and difficult situations. A slippery stem is all dependent on the clamp. You will need a tight and sturdy clamp for precise handling on the road with good tracking.
Why do you need a new mountain bike stem?
Control– The number one reason of having a good mountain bike stem is that it gives you maximum control when cycling. Shorter stems are the best because of their quick response. On the other hand, longer stems provide a smooth performance but they are not very responsive.
Balance– Another benefit of bike stems is that they determine how you balance your body when cycling. When climbing, short stems are the best in terms of balance because the shorter ones move your weight backward,
Design– If you are not satisfied with the design that comes with your mountain bike, you can buy another one because they are available in different colors. They are also cheap and easy to install.
How to choose the best mountain bike stem
When searching for the best, you should check the following features;
Length– The length of the stem is the most important thing you should check when buying. If you want a stem that will give you very smooth rides, you should consider a short stem. The best stem length should be 50mm-80mm. Again, the handlebar is also another important feature that will determine the type of stem you should buy.
Construction – In terms of durability, CNC stems are the most durable. They are also strong that stems which are made of other materials.
Rise/Angle of the stem- This refers to the angle in which the stem is bent. You should consider a stem that allows a 5-6 degrees rise.
Frequently Asked Questions
How long should a mountain bike stem be?
A good stem should be 50-80mm long. Long stems provide the best stability when climbing.
What are the benefits of using a shorter stem?
The major reason why most people opt for shorter stems is that they are more responsive as compared to the longer ones.
Rounding up the best bike stems reviewed in this article, I carefully chose from a wide range of available stems out there. They were picked based on their performance, durability, versatility, price, and general ratings.
These bike stems are well-rated across many platforms, and they have been tested and recommend by biking enthusiasts everywhere.
My top pick is the FIFTY-FIFTY Aluminum Alloy Mountain Bike Stem, which has a whopping 4.9 stars out of 5 on Amazon. This bike stem is the definition of high performance, and it can take hits from rough riding without getting bad.
The price is a bit higher than many others on this list, but the quality speaks for itself.
However, the Bavel Aluminum Alloy Mountain bike stem is the perfect choice if you’re on a budget. It works like a lot of the more expensive models, and it suits several types of bikes. Be careful with the handling, though, because it is not as durable as some of the others.
When you’ve found the best mountain bike for your criteria, sometimes it’s worth looking at adapting the riding style to ensure a comfortable ride.
You may notice that the selection of our best bike stems is all made of aluminum instead of other materials such as carbon fiber, which has been intentional due to the cost of a carbon stem in comparison to other materials.
Whatever pick you make from my bike stems, always ensure that it fits the bike you’re getting it for. The length matters, and it decides how much you will enjoy your bike stem.
Some of the bike stems on this list come in different sizes so you can make a good pick that you won’t end up regretting.
