Best Mountain Bike Stem Buying Guide & FAQ

Choosing the right stem for your bike involves learning more about the different stem types available and how you can match your mountain bike to the best stem in terms of length and adjustability. The following guide will help answer the most frequently asked questions regarding this vital component and will also show you how you can upgrade your bike by replacing the old stem with a brand new one from our list.

What to Consider When Buying a Mountain Bike Stem

  • Length

Stem length can make or break your overall experience when riding your mountain bike. Increasing or decreasing this length can make a vast difference when it comes to steering, balance as well as posture. Making small adjustments can go a along way and simply upgrading your stem will make your bike feel brand new. Downhill riders and four-cross cycling fans require speed and a shorter stem to gain better control over their wheels. Mountainous terrain can get tricky with so many unpredictable surprises along the trail, so you need a reliable stem that will help you make quick detours to avoid colliding with a rock or a tree. You can easily steer the bike while going downhill and climb off easily if you have a short stem installed.

Long stems are more suitable for cross country cycling that involves forest trails and steep descents. Investing in a longer stem means more stability in terms of steering and a more comfortable riding position. Cycling long distance can cause significant strain on your back and shoulders, so installing a 120mm stem for example will help you steer better and gain more balance while riding down narrow single-track trails. Even weight distribution is also possible with a longer stem and this can be a blessing during long and tiresome rides. There are so many options that you can try before finalizing your purchase and you can always experiment with different stem lengths in order to find the best fit for you and your bicycle of choice.

  • Durability

Durability is an important factor and the key to a long-lasting stem. The last thing you need is for your bike to break down during a race or in the middle of a forest trail. Therefore, investing in a quality component is a must. There are three main materials of choice when it comes to making stems. The most common material is none other than aluminum due to its strength and weight. You will find that many bike manufacturers incorporate aluminum 6061 in their production process. Many mountain bike stems are made of this specific type of aluminum alloy which is also used in aircraft manufacturing. Aluminum stems are budget friendly and are mostly built for road, trail and mountain bikes.

Light and hollow stems are now available thanks to advancements made in forging techniques over the years. There are also more expensive stems out there made of 2014 aluminum alloy and ones made of carbon fiber. A carbon mtb stem is a rare find and is only used in special cases and with incredibly expensive and professional cross-country race bikes. Carbon stems were built for high speeds and intense long-distance cycling, so they are more expensive and less affordable compared to aluminum-made stems.

The third and most coveted option is the titanium stem. These stems are much more expensive, but they are resistant to corrosion. On the other hand, they are flexible and will require large diameter tubes in order to make them stiffer.

  • Stem Rise

You also need to consider the stem rise and this has to do with the angle of the stem itself. The angle is measured in degrees and is directly linked to the positioning of the bike and its handlebars. Some stems have a moderate rise while others like the above Ritchey 4Axis stem model have an 84-degree rise. A stem with a 10-degree angle between the handlebar clamp and the steerer has a 10-degree rise. Moderate rise stems can be reversed, and this turns the rise into a drop. A 10-degree drop allows racers to ride more aggressively and their entire posture changes accordingly. A zero-rise stem is basically parallel to the ground and is usually found on regular downhill mountain bikes. Rise angles can be both positive and negative, so you can easily reverse the stem to lower the bar as well. You can achieve better handling response and more comfort while pedaling by simply experimenting with different rises. Keep in mind that a higher rise will help keep your body in an upright position.

  • Bike Type

The bike you own also dictates the type of stem you need in order to achieve your cycling goals. XC bikes were designed for racing and therefore require a long stem with a zero or flat rise. The ideal XC stem is around 100 to 120 mm long. Trail bikes need shorter stems that are around 60 to 80mm in length with a moderate rise. These dimensions are ideal for quick steering responses on narrow trails. DH or downhill bikes require durable downhill stems with a much shorter length of around 40 to 50mm. These measurements offer the rider more control and precision during descent.

CNC vs. Forged

CNC is short for Computerized Numerical Control and this process involves a computer and a 3D machine that takes the information provided by the computer in the form of numbers and turns it into an actual product with a precise and almost perfect finish. This smooth high-end finish requires more time, but the results are always consistent. CNC machined stems have a better finish compared to forged stems and do not require tumbling or polishing.

The forged stem also starts off as a solid block of aluminum and is forged into an actual bike component by pressing or pounding the metal under high pressure. The end product can sometimes be less angular and rougher compared to CNC machined stems and thus requires polishing or tumbling to give it a smoother and more polished finish. Forging is a faster process compared to CNC and some prefer it over 3D cutters since it delivers a denser grain structure and a stiffer stem.

How to Change Your Mountain Bike Stem

You can easily upgrade your bike stem by following the steps below:

  • The first step involves loosening the bolts that belong to the faceplate. Alternate between loosening the top and unscrewing the bottom bolt in order to evenly distribute the pressure on the bars.
  • Keep one bolt in place and remove the rest but make sure to press the faceplate against the handlebars while you loosen the remaining bolt. The handlebars must remain in the same position while you remove the faceplate. Once this step is complete, you may proceed to hang the bars down without rubbing them against the forks.
  • You also need to remove the top cap bolt and any stem insertions located above the stem. The top cap itself needs to be removed as well.
  • This step involves loosening the stem and this can be done by simply unscrewing its bolts. Remove the stem once you finish loosening the bolts.
  • Grab your new stem and remove the faceplate by loosening the bolts. This step makes installing the handlebars much easier to do later on.
  • The two bolts that belong to your new stem need to be loosened before sliding the new stem onto the streerer tube. Make sure that you return the spacers to their original position once you’re done.
  • Return the top cap to the stem and remember to tighten the bolt before you proceed to the next step.
  • Grab the handlebars and mount them on the new stem before returning the faceplate and then screwing the bolts into the stem.
  • Use the markers found on the bars to line them up properly.
  • Tighten the faceplate by securing each bolt but make sure that you end up with a correctly mounted handlebar.
  • The final step involves lining up and securing the stem. You need to straddle the front wheel in order to properly center the stem. Use your thighs to grip the wheel while you work. Make sure that all the bolts are evenly tightened. Twist and push the handlebars in order to confirm that they are indeed stable and securely connected to the stem.

Best Mountain Bike Stem FAQ:

Q: What is a mountain bike stem?

 A mountain bike stem forms a bridge between the steerer and the handlebars. Threadless stems are the most common stem type found on most bikes nowadays. Each stem has a rear clamping end that connects it to the steerer tube of the fork. Mountain bike stems are available in a wide range of lengths with different rises and they are secured to the bike using front and rear bolts.

Q: What size stem should I use?

This depends on your personal preference and your go-to bike for recreational cycling. Nowadays, you can easily experiment with different stem sizes by requesting a professional bike fit from the best local bike shop available in your city. Many shops offer this service in exchange for a small fee. You can take advantage of this service to test out as many stem sizes as possible. The key to a more aggressive and aerodynamic style of cycling lies in a longer stem. A comfortable riding position with minimal stretching and less strain on your shoulders and arms can be easily achieved by installing a short stem. This will decrease the distance between the bars and the saddle.

Q: What is the stem height?

Every mountain bike has a cockpit where the grips, stem, handlebars and brake levers are located. A slight change in stem height can alter your reach and weight distribution on the bike.  You can control the stem height by simply changing the location of the spacers. Placing the spacers above the stem will lower the handlebars. If your goal is to sit in a more upright position on the saddle, then you can place the spacers right below the stem.
