A tiny question
In search of marginal gains in bicycle appearance (I already have color-matching presto stem caps...)
I have external cable routing, in which the rear brake cable runs along the bottom of the top tube. The little rubber rings (i think they are called donuts???) Always slide back toward the seat tube, and so (1) don't do their job of keeping the cable away from the paint, and (2) look silly.
What can I do?

Are they really necessary? I don't have it on any of my bikes and don't have problems with the cable contacting the TT. Get rid of them. They're like the dork disk on your rear wheel.

Cut them off maybe, especially if they don't work?
If it was me, and I wanted it to look neat and keep the cable from touching, I'd slide a short piece of shrink tubing over it. But, anything you put on the cable, if it rubs very much it will still eventually scuff the paint off so maybe you're better off with just the cable.

Position them correctly...that is far enough away from where the cable goes into the housing...and then apply just a very small (tiny) amount of rubber cement to hold it in place. That shouldn't interfere with the operation, and would be easy enough to remove if/when you need to remove the cable.

I dealt with sliding donuts for >15 years and really anything will do - nail polish, rubber cement, a little hot glue, RTV silicone gasket sealer... Whatever is handy.

2. I don't do "marginal" performance gains. I work hard for 3-4 weeks, make LARGE gains, then slack off for a few weeks and lose it all...and repeat...
