The Ultegra cable sheaths work great, I've had no issues with mine for 2 years. You must wipe down the frame with IPA just before applying though. It's the only way to get good adhesion.
Weird, I tried them on the fork of my Bob Jackson and I’ve had to replace it 3 times in 3 years. It might be that they’re following a curve? But it always starts peeling at the bottom and works it’s way up.
Ah. I have always wrapped the wire around the fork and used the channels for running the wire underneath the top tube. It's less likely to get jostled that way and take on far less water. I can see how you would have challenges.
