# The Ultimate Guide to Internal Cable Routing: Installing Your Carbon MTB Handlebar with Confidence
When it comes to mountain biking, having the right handlebars for a bicycle can significantly impact your riding experience. An increasing number of riders are opting for carbon handlebars due to their lightweight nature, stiffness, and vibration-dampening properties. However, to fully enjoy your carbon MTB handlebar, it’s important to ensure that it’s installed correctly, particularly when it comes to internal cable routing.
Internal cable routing is followed by many bike manufacturers as a design choice, providing a sleek, clean look while also protecting the cables from dirt and damage. However, routing cables can seem daunting, especially if you’re new to bike maintenance. In this article, we will explore the steps necessary for successfully installing your carbon MTB handlebars with internal cable routing, ensuring a professional finish and a reliable setup.
## Understanding the Benefits of Internal Cable Routing
Before diving into the installation process, it is helpful to understand why internal cable routing is favored by many cyclists and manufacturers.
1. **Aesthetics**: Internal cable routing provides a cleaner look by hiding the cables within the frame. This sleek design eliminates the clutter associated with external cables, giving your bike a modern and professional appearance.
2. **Protection**: Cables routed internally are typically less exposed to the elements, meaning they are less likely to get dirty or damaged. This protection extends their lifespan and can enhance performance over time.
3. **Aerodynamics**: Less airflow disturbance from exposed cables can contribute to improved aerodynamics, allowing for better efficiency during rides.
4. **Reduced Noise**: Internal routing minimizes noise caused by vibrations and rattling cables, providing a quieter ride.
With these benefits in mind, let’s look at how to correctly install your carbon MTB handlebar with internal cable routing.
## Tools Needed for Installation
Before starting the installation, gather the following tools:
– Allen keys (usually 4mm, 5mm, and 6mm, depending on your bike)
– Cable cutters
– A cable routing tool (optional but recommended)
– Electrical tape
– A clean rag
### Step 1: Prepare Your Workspace
Having a clean, organized workspace will make the installation process smoother. Ensure that your bike is thoroughly cleaned to avoid dirt getting into your cables or housing. It’s also helpful to have a bike stand, as this will make it easier to work with your bike.
### Step 2: Remove Existing Handlebars
If you are replacing existing handlebars, follow these steps:
1. **Detach Components**: Start by removing any components attached to your existing handlebars, such as brake levers, shifters, and grips. Use your Allen keys to loosen and remove these parts.
2. **Remove the Handlebars**: Once all components are detached, loosen the clamping mechanism on the stem and lift out the handlebars.
3. **Check Cable Housing**: If your bike has internal cable routing, inspect the cables and housing. Make sure they are in good condition and free of frays or excessive wear.
### Step 3: Prepare the New Handlebars
Before installing your new carbon MTB handlebars, ensure they are compatible with your existing stem and components.
1. **Measure and Cut Cables**: If you are replacing cable housing, measure the necessary lengths for each cable pathway within the handlebars. It’s generally a good idea to add a little extra length to accommodate movement and adjustments. Use cable cutters to cut the cables cleanly.
2. **Install Cable Housing**: Thread the new cable housing through the designated openings in your carbon handlebars. Depending on the number of cables and the routing design, this may take a bit of finesse.
### Step 4: Route Cables Internally
Routing cables can be one of the most critical stages of the installation process.
1. **Use Director Tool (if available)**: A cable routing tool can help guide the cables more easily through various frame sections. Attach the cable to the tool and let it pull through.
2. **Employ Electrical Tape**: If you do not have a routing tool, you can use electrical tape to tape the end of the cable to something stiff (like a straw or a spare piece of cable). This will allow you to route the cable smoothly through the internal channels.
3. **Guide Cables**: As you pull the cables through the handlebars, ensure they lay flat and do not twist. It may take patience, but this step is crucial for long-term functionality.
### Step 5: Attach Handlebars to Stem
Now that the cables are routed properly, it’s time to attach your new handlebars to the stem.
1. **Align Properly**: Position the front of your handlebars at the desired angle. Ensure that any cables are not pinched or overly stretched as you do this.
2. **Tighten Stem Bolts**: Gradually tighten the stem bolts using your
