Help with creaky cables on my Merlin(5 posts)

Help with creaky cables on my MerlinCKS
Aug 15, 2002 8:02 AM
I have a Merlin Agilis, and have an aweful metal-on-metal creaking noise coming from the shifter cables, I think at the point where they are attached to the braze-ons located on the head tube. The noise does not occur when riding, but when I turn my handlebars back and forth to a greater degree. Thus, it's not a huge issue, but annoying nevertheless...

Any suggestions?

First, are your cable housings long enough? They should be long enough so you can turn the handlebars all the way till they bang on the frame.

Second, when I can make it work, I prefer to cross the cable housings so that the rear shift cable attaches to the left side of the head tube and vice versa. The cables cross again under the down tube. That way the cable housings don't rub as much on the head tube.

I solved this probem with Shimano palstic ferrels.
Creaking gone.

To understand what you're hearing, you have to understand what is involved. Shift cable housing has a series of wires that run parallel to the housing, for the entire length of the housing, all the way around, which is then coated in plastic. When the housing is first cut, the wires recede into the housing a tiny bit. Over time, the wires work themselves through the plastic until they make contact with the cable adjusters.

There are two fixes here. One is to just snip about 2mm off of the housings, the other is to snip a little bit off, and add a plastic ferrule, which should last much longer.
