Routing Shimano controller cable on carbon bar?

[P00KIENRAYRAY]

Hey, so I'm purchased a used carbon bar from a buddy of mine to replace the alloy one on my Canyon Spectral On. Mainly to color match my ebike and to give a more customized look. I'm not expecting any performance or weight advantages.

This is my first bike with Shimano system. The stock bar has 2 holes for the controller cable to go into the bar, then out of the bar at the stem, which then connects to the display. Clean and out of the way.

Definitely not gonna drill into the carbon bar...but I'm trying to think of ways to mount the controller and the display onto the carbon bar, and routing the cable in the cleanest and tidiest way possible. Just use electrical tape or zip ties? I currently have the controller mounted in between the left grip and left brake lever, but suppose I can move it in more towards the stem since the brake and dropper remote clamps will be in the way.

Any ideas would help, thanks.

On mine I tend to route the Shimano connecting wires along the brake cables. You can use things like zip ties, or plastic spiral wrap or connectors like these (ones for e-shift): S-Hooks and Bridges | Jagwire

Thanks! For some reason I was thinking the only way to route it was along or inside the bars. Glad I reached out!

it's fairly easy to route the wiring through a Di2 bar but you do need the correct length Shimano wires because of the way the wiring has to double back on itself
if using a display I wouldn't bother. it makes much mose sense to do it with the bluetooth EN-EW100 junction control box

I'm not familiar with the bluetooth junction box. Gotta look into it. And yea, my stock bar is Di2 compatible apparently. It has the holes for access as well as the bottom grooves on the ends for the cable to sit.

So what I'm understanding about the EN-EW100, it just bypasses the display, and goes straight into the controller/e shifter?

Yes. But also allows mobile connectivity, mode change and an LED light that shows mode/errors/battery warning.
So you also have the option of doing away with a mode controller all together.
Ideally you want the EN EW100 mounted externally onto another cabke/hose but it could be mounted internally if you were after as clean a look as possible

Ah ok. Interesting. I don't care for the display, and decluttering my cockpit is ideal. Only websites I see selling em are in Europe. I'm gonna give Shimano USA a call to see if they're avail stateside.

Did you get all this figured out and now have a clean cockpit? I have a EN EW100 available and also wanted to see if you still and your stock Di2 compatible handlebars as Im in search of one for my bike. Let me know and happy riding!

Mounting the Shimano system's controller and display onto a carbon bar without drilling requires some creative solutions for a clean and tidy setup. Here are a few ideas to achieve this:

Cable Management​

1. Zip Ties: Use small, high-quality zip ties to secure the cables along the underside of the bar. Look for ones in a color that matches the bar for a cleaner look. You can cut off the excess for a neat finish.
2. Cable Wraps: Use spiral cable wraps or Velcro straps to bundle the cables together. This can help keep everything tidy and can be easily adjusted if needed.
3. Cable Clips: Adhesive cable clips can be used to route the cables along the bar. Make sure they are strong enough to hold but gentle on the carbon finish.

Mounting the Controller and Display​

1. Bar Mounts: There are several aftermarket bar mounts designed for various devices that might work with your Shimano system. Look for adjustable mounts that can securely hold the controller and display without needing to drill.
2. Relocation: If moving the controller towards the stem makes the setup cleaner, you can use the space between the stem and brake levers. This area often has less clutter and can make the controls more accessible.
3. Custom Mounts: Consider 3D printing a custom mount that fits your specific needs. There are online services where you can design and print mounts to fit perfectly on your carbon bar.

Example Products​

1. Shimano STEPS Handlebar Mount: Check if there’s a specific handlebar mount available for your Shimano system. These mounts are often designed to fit seamlessly with the components.
2. K-Edge Mounts: K-Edge makes durable mounts for various devices that could be adapted for your setup.
3. Race Face Stem Cap Mount: A stem cap mount can hold the display in a central, easily viewable position.

Installation Tips​

1. Protective Padding: Use rubber or silicone padding under zip ties or clips to prevent damage to the carbon bar.
2. Test Placement: Before securing anything permanently, test different positions to find the most ergonomic and visually appealing setup.
3. Regular Checks: Periodically check the mounts and control cables to ensure everything remains secure, especially after rides.

By using these methods, you can achieve a clean, tidy setup on your new carbon bar without compromising its integrity.
