I want to run a brake hose through my steerer tube and need space for a clean exit.
My idea is to attach a kevlar spoke to the crown of the fork using the fender attachment point. Then I can run that inside the steerer to a length of threaded tube which the steerer cap is screwed into. I will fit a sleeve at the top of the fork to handle the pressure from the stem.
The Kevlar is easily strong enough for the preload and then my steerer is empty and I don't need to make a custom expander plug.
Aside from the hassle of it, do any of you experts see a problem with this?
