Designed to organize your handlebar cables, these guides let you do away with wraps and tape on your mast. They can be positioned wherever you want them and let you manage 4 cable housings and a computer wire. These precision machined guides cleanly and elegantly keep your cables under control and looking nice.
They are available in the two most common mast sizes- 1-1/8 and 1-1/4 inches (28.6 and 31.8mm). You can clamp them anywhere on your mast as long as it is straight and smooth, as most masts are. If you have an older mast with welded on cable stops, you will probably have to stick with the old guides or upgrade to a new mast.
Height is 3/8 inch (9.5mm). The allen wrench for the clamp bolt is 3mm.
1. How do these work?
These cable guides work by clamping on to your handlebar mast. They have 4 cable housing slots and a computer wire slot. They are designed to nicely organize your cable housing on your handlebar mast.
2. How do you install them?
The guides fit on handlebar masts with at least one smooth end. Usually, they are installed by sliding them up from the bottom after removing the mast to stem collar clamp. They can also be installed from the top if you have a removable top stem.
If you are retrofitting them to a bike with existing cabling, you will want to arrange the cable housing in their slots before sliding the guide up the mast. To do that, temporarily remove the 4mm allen head bolt from the guide and slip the housing through the gap. It is sized for this purpose.
3. I have cable stops now. Can I replace them with these?
Unfortunately, probably not. These guides are designed for smooth handlebar masts. If you have welded on stops, it's unlikely you can get the two to work together.
4. How do I know which size to get? I don't know the OD of my handlebar mast.
Most older bikes have 1-1/8 inch (28.6mm) OD handlebar masts. Some newer bikes have 1-1/4 inch (31.8mm) OD masts.
