today I was installing brand new GRX brakes into new frame. It was not my first time, I've already build 10+ bikes, I messed up through. I inserted rear brake hose without any issues, I had my guide, it was OK. I wanted to add Jagwire Internal Housing Damper, but it didn't go well so I had to take brake house out and then back again.
Second time it got caught by internal part of cage holder (not removable), so I had to take a little bit more time but I got it outside with little more force.
But then I noticed, that hose feels weird in hand. So I took a deep look and found out, that the whole part which was going inside frame was scratched a lot.
If this was for mechanical brake, I won't be concerned at all, because I know there is metal cover inside. But what about this hydraulic hoses? Should I be concerned? Deepest one is on pictures no. 2 and 5. I'll have to shorten hose, but this part will be about 5-10 cm outside the shifter.
I have spare hose but I think this is only esthetic problem and it's gravel bike, so it'll get many more scratches during few rides. Thanks for other opinions.
