Last Updated on October 24, 2026 by Jaxon Mike

Raising the handlebars on your Scott mountain bike is a great way to improve your comfort and control. It’s a fairly simple adjustment that can make a big difference on the trail. You can often achieve this by adjusting your stem or by adding spacers above the stem.

Many riders find that a slightly higher handlebar position reduces strain on their back and wrists. This adjustment can help you maintain a more upright posture, which is especially helpful on longer rides. It can also affect your bike’s handling characteristics, potentially making it feel more stable.

• Adjusting stem height for comfort.
• Using headset spacers for a lift.
• Ensuring proper bolt torque.
• Checking brake and shifter cable length.

Let’s walk through exactly how you can raise your handlebars step by step.

Adjusting Your Scott Bike’s Handlebar Height

Raising the handlebars on your Scott mountain bike is a straightforward adjustment that can significantly boost your comfort and control on the trail. You might be experiencing hand or wrist fatigue, or perhaps a sore back after longer rides. Many riders find that a slightly higher handlebar position reduces this strain. It can help you maintain a more upright riding posture, which many cyclists prefer. This change can also influence how your bike handles, sometimes making it feel more stable, especially on descents.

Understanding How Handlebars Are Raised

There are a couple of primary ways to achieve a higher handlebar position on your Scott bike. The most common methods involve adjusting your stem or adding headset spacers. The stem is the part that connects your handlebars to the fork’s steerer tube. The headset is the bearing system that allows your fork to turn. Understanding these components is key to making the right adjustment for your needs.

Method 1: Stem Adjustment and Spacers

This is often the easiest route for many riders. Your bike’s stem can usually be flipped or rotated to change the handlebar angle. Also, headset spacers, which are small rings that sit around the steerer tube, can be rearranged. You typically find these spacers both above and below the stem. Moving them from below to above the stem will give you a bit of lift.

Flipping Your Stem

Some stems have a slight upward or downward angle built into them. If your stem has this feature, simply loosening its bolts and rotating it 180 degrees can provide a noticeable change. You’ll want to check your specific stem model to see if this is an option. This is a quick way to gain a few millimeters of height and is easy to reverse if you don’t like the feel.

Rearranging Headset Spacers

Most modern mountain bikes use an integrated headset with spacers that sit above and below the stem. To raise your handlebars using this method, you’ll need to loosen the stem bolts and the top cap bolt. Then, you can move the spacers from beneath the stem to above it. Remember, you need to keep at least one spacer above the stem to properly preload the headset bearings. It’s also good practice to have a spacer or two above the stem for visual balance and to prevent the top cap from bottoming out on the steerer tube.

Before you start, it’s helpful to know how many spacers you have and their current positions. Take a moment to visualize the stack of components on your steerer tube: top cap, spacers, stem, then more spacers (often) before the fork crown. We’re looking to move spacers from below the stem to above it.

Method 2: Installing a New Stem

If flipping your stem or rearranging spacers doesn’t give you the height you need, you might consider installing a new stem. Stems come in various lengths and angles. A stem with a steeper rise angle (e.g., a 35-degree rise compared to a 6-degree rise) will naturally position your handlebars higher. You can also choose a stem with a shorter reach, which often pairs with a higher rise to improve comfort.

When selecting a new stem, consider your riding style and the type of trails you frequent. A more aggressive rider might prefer a shorter, steeper stem. A rider focused on endurance or bikepacking might opt for something that promotes a more relaxed posture. It’s a good idea to research stem specifications and perhaps consult with a local bike shop if you’re unsure.

Step-by-Step Guide to Raising Handlebars

Let’s walk through the process of adjusting your handlebars using spacers, as this is the most common method for a modest height increase. Remember to work on a stable surface, like a bike stand or a sturdy workbench.

Gather Your Tools

You won’t need a huge toolbox for this. Most likely, you’ll need:

• A set of metric Allen wrenches (hex keys), typically 4mm, 5mm, and 6mm.
• A torque wrench is highly recommended to ensure you don’t overtighten or undertighten bolts.
• Possibly a soft mallet or rubber hammer if parts are stuck.
• A clean rag for wiping parts.

Loosen the Stem Bolts

First, you’ll need to loosen the bolts that clamp the stem to the fork’s steerer tube. There are usually two pinch bolts on the back of the stem. Loosen these about halfway. Next, locate the top cap bolt on the very top of your steerer tube. Loosen this bolt, but don’t remove it completely just yet. This bolt is what preloads the headset bearings.

Remove and Reorder Spacers

Once the bolts are loose, you should be able to slide the stem up and off the steerer tube. If it’s stuck, a gentle tap with a rubber mallet might help. You’ll then see the stack of headset spacers. Decide how many spacers you want to move from below the stem to above it. Carefully remove the spacers from below and place them on top of the stem. Ensure you leave at least one spacer above the stem for proper headset function.

Reassemble and Tighten

Slide the stem back onto the steerer tube. Reinstall the spacers you moved to the top, ensuring they sit neatly. Now, reattach the top cap and screw in the top cap bolt. Tighten this bolt just enough to remove any play in the headset. You can check this by applying the front brake and rocking the bike back and forth; there should be no knocking or looseness. Many experts suggest tightening this bolt to about 4-5 Nm (Newton-meters).

After the headset is snug, align your stem perfectly with the front wheel. Then, tighten the two pinch bolts on the back of the stem. It’s best to tighten these alternately and evenly, rather than tightening one fully before the other. Consult your stem manufacturer’s specifications for the correct torque, but a common range is 5-6 Nm. Using a torque wrench is the safest way to do this.

Important Considerations and Checks

After making your handlebar height adjustment, there are a few crucial checks you must perform. Skipping these steps could lead to performance issues or even safety hazards.

Check Brake and Shifter Cable Length

Raising your handlebars can sometimes shorten the effective length of your brake and shifter cables. If you’ve made a significant change, you might find that your cables are now too short. You’ll want to turn your handlebars from side to side in a full lock-to-lock motion. If you feel any tension or restriction in the cables, they are too short.

If your cables are too short, you have a few options. For minor adjustments, you might be able to re-route them slightly to gain a little slack. For larger adjustments, you may need to install longer cables. This is a more involved process, often requiring new cable housing and inner wires.

Test Ride and Fine-Tuning

Once everything is tightened and adjusted, it’s time for a short test ride. Start on a familiar, relatively smooth path. Pay attention to how your body feels. Are your hands more comfortable? Is your back less strained? How does the steering feel? Make small adjustments as needed. Sometimes, a change of just 5mm can make a big difference. This is why a torque wrench is so helpful; it allows for precise, repeatable adjustments.

Final Checklist Before Riding

Before you hit the trails with your newly adjusted handlebars, run through this quick checklist:

• Stem Bolts: Are all stem pinch bolts securely tightened to the correct torque?
• Top Cap Bolt: Is the top cap bolt tightened enough to remove headset play, but not so much that it binds the steering?
• Handlebar Orientation: Is the handlebar centered and straight relative to the stem?
• Cable Clearance: Do brake and shifter cables have enough slack for a full range of steering motion?
• Brake Function: Do your brakes engage properly and feel firm?
• Shifter Function: Do your shifters operate smoothly through all gears?

Conclusion

You’ve learned how to adjust your Scott mountain bike’s handlebar height to improve your riding experience. Whether it’s by flipping your stem, rearranging headset spacers, or even considering a new stem, these adjustments can make a real difference in comfort and control. Remember to always tighten bolts to the correct torque and double-check your brake and shifter cable slack. Take your time, follow the steps carefully, and then enjoy a test ride. Your next step is to get your tools and make that adjustment you’ve been planning!

Frequently Asked Questions

How high can I realistically raise my handlebars?

The amount you can raise your handlebars depends on your specific bike’s setup. You can typically gain a few millimeters by flipping the stem or rearranging existing spacers. For a more substantial lift, you might need to install a new stem with a steeper rise angle. Always ensure you don’t run out of steerer tube for the top cap and stem clamp.

What if my brake or shifter cables are too short after raising the handlebars?

If you feel tension or restriction in your cables when turning the handlebars, they are too short. For minor adjustments, you might be able to re-route them for a bit more slack. If that doesn’t work, you will likely need to purchase and install longer brake and shifter cables. This is a more involved repair but essential for safety.

Do I need a torque wrench to adjust my handlebars?

While not strictly required for every single bolt, a torque wrench is highly recommended. It ensures you tighten the stem and top cap bolts to the manufacturer’s specifications. Overtightening can damage components, while undertightening can lead to loose parts and a dangerous loss of control. Proper torque is key for safety and component longevity.

Can raising my handlebars negatively affect my bike’s handling?

Yes, raising your handlebars can change your bike’s handling. A higher bar position typically shifts your weight slightly backward, which can make the front end feel lighter and potentially less responsive on climbs or quick turns. It can also make the bike feel more stable on descents. You may need to experiment to find the sweet spot for your riding style.

Is it okay to have no spacers above my stem?

No, you should never have zero spacers above your stem. At least one headset spacer is needed above the stem to allow the top cap to properly preload the headset bearings. Without this, your headset will be loose, leading to play in the fork and potentially damage to your headset bearings. Some bikes also benefit from an additional spacer above for aesthetics and to prevent the top cap from bottoming out.
