I have a new carbon roadbike frame with in the head tube a cable stop built in.

From the outside of the headtube the outercable ends in it, and then it guides the innercable through the frame.

This cablestop (alu hollow tube) can be seen at the inside of the headtube. It's partly uncovered and I think it’s a bad construction. Vulnerable for breakingout (see image)

 

I want to cover it on the inside with tiny pieces of carbon so the cable stop will be totally locked up on all sides.

 

Think I only need a few pieces of carbon of 2 x 4 cm and some resin and hardener.

What do you advise me?

Hope you can help me out

Do I understand it wrong?
The stopper lays already partly in carbon so what's the hype with corrosion?

I thought about putting epoxy glue over it. But had the idea to use something like the carbon fibre repair kit, (but then a smaller kit)
Why should that not work?

This is my second frame first frame that came in had paint issues and needed to wait 3 months for replacement although it was new.
So I know that this is a design thing, the other frame had exactly the same stopper. To change it for another will not help.
I rather void warranty instead of waiting till this part crash. lol

So you guys say I use 2 best components glue / filler? do I  not need to reinforce that with fibres?
