The Tools You’ll Need

Before diving into the process, gather the following tools:

1. Cable housing cutter
2. Cable cutter
3. Marker or pen
4. Safety goggles
5. Clean cloth

Step-by-Step Guide

1. Prepare the bike

Start by securing your bike in a repair stand or flipping it upside down, ensuring it’s stable and won’t wobble during the procedure. This will make the task safer and more convenient.

2. Determine the right length

Measure the length of cable housing required and mark it with a pen or marker. Remember to add a couple of extra centimeters as you can always trim down excess housing later.

3. Ensure clean cuts

Using the cable housing cutter, position it perpendicular to the housing and squeeze the handles to achieve a clean, even cut. Avoid twisting the cutter to prevent any fraying or jagged edges.

4. Chamfer the cut end

Take your cable cutter and gently flatten the edges of the cut housing at a slight angle. This chamfering helps the cable to slide smoothly and minimizes the risk of fraying that could lead to poor shifting or braking.

5. Clear any debris

Utilize a clean cloth to carefully wipe away any debris from the freshly cut housing. This ensures a clean and smooth path for the cable.

6. Install end caps

Slide a cable end cap onto each end of the newly cut housing. These small metal or plastic ferrules shield the cable and prevent it from fraying.

7. Test the fit

Double-check the length of the housing by installing it on your bike. Ensure it fits snugly and leaves room for handlebar rotation or frame movement.

Frequently Asked Questions

1. Can I use regular pliers instead of a cable housing cutter?

While it’s possible to use regular pliers, a cable housing cutter provides cleaner cuts and reduces the risk of damaging the housing.

2. What happens if I don’t chamfer the cut end of the housing?

Skipping the chamfering step may cause the cable to catch or fray, resulting in poor shifting or braking performance.

3. How can I prevent fraying of the cable housing?

Ensuring a clean cut, chamfering the end, and using cable end caps are effective ways to prevent fraying.

4. Can I reuse old cable housing?

Reusing cable housing is generally not recommended, as old housing may have worn or damaged areas that will affect the performance of your bike.

5. Should I replace the cable along with the housing?

It is recommended to replace the cable when you replace the housing, as they wear out together.

6. How often should I replace cable housing?

The frequency of replacing cable housing varies depending on usage and condition. Typically, replacing it once a year or if you notice significant wear is recommended.

7. Can I cut cable housing with a blade or knife?

While using a blade or knife is possible, it is more challenging to achieve a clean cut and poses a higher risk of injury.

8. Do I need professional help to cut cable housing?

Cutting cable housing is a relatively simple task that can be done at home without professional assistance.

9. Can I use cable housing for both brakes and gears?

While cable housing is generally interchangeable, specific types and lengths are optimized for either brakes or gears. It’s best to use the appropriate housing for each system.

10. Are there different sizes of cable housing?

Yes, cable housing comes in various sizes to accommodate different bikes and components. Ensure you select the correct diameter for your specific needs.

11. What should I do if I cut the housing too short?

If you accidentally cut the housing too short, you will need to replace it with a new piece.

12. Can I cut cable housing while the cable is still installed?

It is possible but more challenging to cut cable housing when the cable is still installed. It’s generally easier to remove the cable before cutting the housing to achieve more accurate results.

Remember, with a little practice, cutting cable housing can become a routine maintenance task that helps keep your bike running smoothly. Following the steps outlined in this guide, you’ll be able to make clean cuts and enjoy improved performance on your rides.
