Best Mountain Bike Stem Reviews
1. Wake Mountain Bike Stem
Wake is a lighter and shorter stem for most bicycles. With a handlebar diameter of 31.8 mm, a steerer tube diameter of 28.6mm, a 45mm mountain bike stem length, and a 130g weight, this universal short mountain bike stem is worth taking a look.
As I see, this bike stem is compatible with road bikes, fixed gear bikes, mountain bikes or MTB, downhill bikes, BMX, etc. It is manufactured with a 6061 T6 aluminum alloy by a durable and high-strength CNC machined.
For easy installation, I connected the original and standard front fork steerer stem with the four-bolt bar clamps to hold the mountain bike handlebar stem safely and securely in place. Even with its easy-to-install system, I still feel safe when using it because of its sturdiness.
I think these top-rated mountain bike stems are ideal for modified, DIY, or upgrade projects. When riding downhill and climbing, I always feel comfortable and safe using these handlebar clamps as it keeps my handlebar secure.
I am a collector, and I have several different colored bicycles. So I am pleased that this product has five different colors that I can use for all my mountain bicycles.
2. Fomtor Handlebar Stem Riser
The Fomtor 35-degree handlebar stem rise is the perfect solution to make my bike more comfortable. It can help you adjust the bar height of your handlebar up to 35-degrees. It will bring the comfort you are looking for without having to compromise the cables of your bicycle.
This stem, with a 60mm mtb stem length option, is suitable for the 25.4 mm handlebar stem and handlebar diameter of 31.8 mm. I like that this bicycle part is half as light as most of the adjustable mtb stems on the market. It is manufactured with CNC machined 6061 T6 aluminum alloy making its high-strength and sturdiness note-worthy.
It is one of the most favorite mountain bike stems for mountain bicycles, track bicycles, BMX, and MTB. What I enjoy most besides the comfort it gives me during my rides is that it is easy to install. I connected it easily to the regular front fork steerer clamp stem using four bolt bar clamps to keep the handlebar secured. This simple installation saved me plenty of time so that I could focus more on complicated tasks.
I also like this product due to the noticeable change in my posture when I ride my bicycle. More extended handlebars caused stress on my back and hands when riding. But after I switched to this handlebar stem rise, the difference was huge. My back and hands now do not feel strained or uncomfortable.
3. Funn Mountain Bike Alloy Stem
Although the Funnduro mountain bike alloy stem can be compatible with a 35mm MTB stem, this product is only available in a 31.8 mm one. But I love to put it on my list as it is a meticulously engineered bike stem for endurance training, trail riding, off-roading, mountain biking, and downhill rides.
This bike stem is light but challenging because of the high quality equalizer that is featherweight but stable and durable enough to last in the harshest terrains and conditions.
It is an all-around shorter stem that is safe and efficient for riding in different types of situations. I love that its price is lower than most bike stems in the market, but it feels, performs, and looks like an expensive piece.
I like how I get to choose the color I want to match my taste and my bike. This bike stem is available in five eye-catching colors perfect for any style and mood.
The Funnduro bike stem is designed by a team of experts and tested by world-class cyclists and riders to create the perfect product for adventures. So I think it is as rugged and reliable when you use it for bike racing.
4. RaceFace Mountain Bike Stem
For a better riding position, I think the RaceFace mountain bike stem is perfect. I like it as this product is forged, molded, and blasted with 6061 aluminum to make it heavyweight and stress-resistant at an acceptable weight.
Its purpose is to transfer or shift more load and weight through the stem body with its interlocking and intertwining U-shaped handlebar clamp diameter geometry instead of going through the bolts to avoid damaging the bike. It also has a faceplate that helps eliminate “stress risers,” which leads to your handlebar to bend, snap, or break.
This stem is relatively easy to install because it bears a four-bolt bar clamp diameter that holds the handlebar securely and firmly in its place. It also comes with an instruction manual, which came in handy for me since it was my first time installing one on my bike. The hex bolts came in prepped and grease, so that was a pleasant surprise.
After installing, I took my mountain bike on a 10-mile ride, and I noticed the change almost immediately. Steering was more responsive, and the handlebars were in a more comfortable position being much closer to me. After the ride, I did not have any neck or back pains because my posture and sitting position changed due to my bicycle’s bar height.
5. Wake Adjustable Mountain Bike Stem
The reason why I put it on my list is that this product works and feels well-built for its very affordable price. With its hollow and universal design, this adjustable 110mm long mountain bike handlebar stem works best and is suitable for most bikes like road bikes, fixed gear bikes, and mountain bikes.
I am pleased to find out and experience first hand that this product is one of the right mountain bike stems I have purchased.
I was worried that it wouldn’t fit nicely on my bike since it is not a stock part. But once I tightened the stem on its four bolt bar clamp diameter, it did not budge or move. I’m sure to say that it is stable and very secure. Let me add that it is relatively easy to install. I did not have to search for ways to do it because it was pretty straightforward, and everything I needed was right in front of me.
I believe this particular mountain bike stem is ideal for tall cyclists. Its up to 60-degree adjustable feature is perfect for tall people and their postures while riding their bicycles.
6. Fomtor Mountain Bike Stem
I love this product as this 70mm MTB stem has a 28.6mm front fork steerer clamp with a 35-degree angle to help adjust the handlebars’ stack height and bar height for your convenience. It is also considered one of the lightest mountain bike stem sets on the market with a 140-gram weight.
This stemp is manufactured and constructed with high-strength CNC machined 6061 T6 aluminum alloy ensuring safe and secure bike rides on any conditions, even cross country and mountain biking. I’m pleased that this heavy-duty product is ideal and compatible with most road bicycles such as mountain bikes, trail bikes, MTB, BMX, carbon fiber bikes, etc.
It is a perfect replacement for my non-adjustable mountain bike stem making my bike rides more relaxing, comfortable, and enjoyable. My mistake was I did not purchase this item sooner. Fomtor offers one of the top-rated mountain bike stems I have tried.
Installation was also a breeze for me, I was just a beginner and had not tried to build and customize plenty of bicycles yet. I set up and connected the original fork steerer stem on the four-bolt bar clamp, which held the handlebars securely and carefully in place.
7. Bavel Mountain Bike Stem
If you are searching for a product that can bring the bars closer to your body to help change your posture while riding, I would recommend this Bavel fixed mountain bike stem. With these mountain bike stems, you can avoid body aches and back pains after your ride.
With its 35mm length, I used an MTB stem length calculator to make sure that this handlebar perfectly fit my mountain bike. Due to its affordable price, I also gave this product to my friends because these best stems can be compatible with a wide array of bicycles.
During the installation, I made sure to grease all contact points to ensure everything works smoothly. I also ensured all holes were hollow and checked for machining debris left behind before inserting any of the titanium bolts.
After installation and positioning the handlebars, you should clean up any excess dirt and grease to prevent any debris and foreign pieces from seeping in. You can use a torque wrench on all the bolts to evenly clamp and bolt them in place.
What I like most is that this item is much cheaper than most handlebars stems on the market. Since this bike part is of high quality materials, I see that it holds the handlebars and the fork tube well and adequately.
8. Wake 60mm Mountain Bike Stem
Wake 60mm universal short stem handlebar clamp is one of the best mountain bike stems in my stem length category. I’m impressed that it is suitable, applicable, compatible with a road bike, fixed gear bike, mountain bike, downhill bike, track bike, MTB, and BMX.
The length and angle help optimize and augment the bike frame fit for a more comfortable riding position and posture. I noticed immediately upon using my new mountain bike stem that it is much comfortable and relaxing riding even on challenging terrains. I was not leaning too forward, which usually causes a strain on my back.
The aerodynamic advantage is a big plus because I do not have to think about having any pain while enjoying my favorite hobby.
I like how this bike stem is made well because as soon as I installed it, the bike part fit as it should.

The 35mm and 50mm stem feature a CloseGap faceplate for a more straightforward and effortless installation. I just need to place right under its bolt and tighten the torque for extra security.
This aluminum alloy bike stem looks sharp and eye-catching. It suits my bike’s style, adding to the aesthetics fittingly. I am so glad that this bike stem comes in five bright and vivid colors, so I could choose which one looked best on my mountain bike.

On top of everything great about this product, this company also has a responsive customer service hotline where you can clarify all your queries regarding the size, length, weight, and design of this aluminum alloy bike stem.
What to Look for When Buying Mountain Bike Stems
When it comes to the top-rated mountain bike stems, the right choice for your bicycle will always rely on a few factors. The most important ones being the type of materials, dimensions of the stem, and the stem type. Here are a few things to consider and study before purchasing the right stems for you.
The majority of road bike stems on the market today are threadless stems which bolts and connects directly onto the fork’s steerer tube. At the same time, the plug-in quill design is on older or cheaper bicycles.
Some stems are designed with extra features like the adjustable rise or computer affixes. In contrast, some for triathlon and time trial racing may be integrated or directly mounted into single stem units.
Aluminum alloy is still the most common and conventional stem material in the low to mid-budget stems. However, carbon fiber models are also a popular and preferred choice for racers, professionals, and riders and hobbyists looking to shed weight from their bike and add a little more comfort and convenience.
Stems are available to fit a wide range of different sizes of steerer tubes with 28.5mm being by far the most common.
A wide variety of clamp sizes is also available to fit the varying handlebar diameters with 25.8mm, and 26mm. They are the standard and regular standard road sizes. Although, in recent years, these have been largely superseded and outmoded by the MTB-inspired oversized 31.8mm bar.
Other Important Factors To Consider
What is a mountain bike stem?
A mountain bike stem is a bike part or piece that affixes and connects the handlebars to the fork or bicycle steers. They come in varying lengths, sizes, and rises. The latest stems are usually between 30 mm and 70 mm long with a bolt at the end and four bolts in the front.
How does it work?
The best stems offer a fundamentally straightforward job. Its purpose and use are to ensure that the handlebars are securely and safely clamped and connected to the fork steerer.
The stem type, dimensions, and materials play a vital role in how a bicycle rides and handles, so it is critical to choose your bicycles’ right ones.
What are the different types of mountain bike stems?
- Cross-Country Race Stem
An MTB XC stem is usually about 100 to 120mm long. It is mounted flat and directly to allow the rider to obtain the stretch-out posture that is optimum and essential for racing. It may be made of carbon fiber to subtract additional weight.
- Trail Stem
A regular trail stem is mid-length with 60mm to 80mm in size with a slight degree of rising about six degrees for a more upright riding posture and quicker steering responses in high-speed and technical single tracks.
A shorter or lesser stem also makes it easier for the rider to transfer their weight over the back wheel when going downhill. Most trail stems are of lightweight and strong aluminum alloy.
- Downhill Stem
The right mountain bike stems for downhill or DH racing are short, can be from a 30mm mtb stem to 50mm mtb stem for rapid and speedy handling and steering responses. Many DH stems are directly mounted or integrated to match certain types and kinds of suspension forks that they bolt precisely onto the top clamp of the downhill forks rather than onto the steerer tube.
Most downhill stems house aluminum alloy, but carbon fiber options and models are available at the top of the market.
Why do you need an MTB bike stem?
Using an MTB stem allows the bicycle to have quicker and speedier handling characteristics and features.
Using a shorter stem gives the bike quicker handling characteristics and attributes and a more responsive feel. Longer stems shift the rider’s body weight towards the front of the bike and put the person in a better and more comfortable pedaling position, especially on those steep and extreme climbs.

This type of stem is interchangeable and tailored depending on the rider’s preference.
Are all MTB stems the same?
One thing I can share with you through this mountain bike stems review is that these stems come in different types and sizes. Each type of stem type is for a particular purpose – for riding downhill, racing, or just a leisurely ride around your neighborhood. You can also choose from different sizes, so make sure to measure your bicycle before getting a new one.
This simple component can change the whole dynamic of your bicycle. Choosing the right mountain bike stems for your MTB depends on its fit and the kind of stem you get for it.
What is the shortest mountain bike stem?
The shortest stem for mtb you can get in the market now is measured 30.5 mm or 31 mm. Although, there are some unconventional and atypical options like the ones of the OnOff Stoic stems with 10mm and 20mm. Another brand called Works Components also manufactures reach adjusting headsets that shorten stems by 5mm.
How to install?
Once you know and purchase the right handlebar stem for your bicycle, it is time to remove and replace your old stem. Here is a step by step on how to install your new mtn bike stem:
Start by removing the old stem. Take out the faceplate bolts while holding the faceplate in position. As soon as you take out the faceplate, the bars will be hanging loose. It is good to use a toe strap to suspend the bars and keep the cable and housing from coiling.
Unfasten the pinch bolts at the steerer tube. Usually, a whole turn is more than enough. After that, remove the top cap by removing the top cap bolt. Pull the stem free of the steerer tube.
Install the new stem and its spacers. Place the bicycle on the ground and ensure that all components and parts are entirely placed without any gaps. Align and configure the spacers and stem to your desired height.
The stems should be a bit above the steerer tube by 3mm. Apply additional spacers to achieve your ideal height. In case the new stem is taller than you like, you may remove a spacer.
Put grease to the top cap bolt before installing the top car. Do not tighten the bolt yet because we need to check a few things first. Before pulling the bolts, stand over your bike to set the bar height to your preference. Check if the bars are centered in the stem. Use a ruler if necessary to check if the handlebars are straight and aligned.
Tighten all the bolts and test if it is snug and to your liking. If you feel a little play, loosen the pinch bolts and retighten it. Continue this step until the shaking is gone. Lastly, check if the bars turn freely and with minimal resistance. Finally, torque the pinch bolts.
With all the factors mentioned in this review, it is not a walk in the park building and customizing if you do not have the know-how. I hope that as you end this best mountain bike stems review, you have a much clearer idea of what you are looking for.
Factors like handlebar width, bar diameter, clamp design, and rise are some of the considerations that you need to focus on to ensure a smooth ride in the future.
