If you look at the first 2 pictures you clearly see damage to the steerer tube, the steerer have been lose and the dustcap have eaten away on it.Sorry with English not being your first language (and I don't have any other) I'm losing what you are saying or meaning. I'm not sure why the damage has happened if it was OK from the start and nothing was taken apart.
Some advices are solid but some are really strange here and on other forums. it is 100% carbon! The shop cutted it and you can clearly see it's carbon. But you need to start recognize the fact that lighting and other things can make things look different.Take it to the bike shop. I doubt the steerer is carbon.
I know I have been stupid in this case.Agree, just don’t be too upset with the smiles on the mechanics faces.
It's 100% damaged, they weren't there from the start and rings around a carbonfork is not good. My fault probably yes.It's almost certainly an operator error rather than a 'Chinacrap' manufacturing problem.
I think the steerer bung isn't being installed correctly. I suspect that the marking on the steerer tube doesn't represent damage. Your local bike shop will be able to advise.
A superficial mark on the surface of a carbon steerer may or may not represent structural damage. I'm not seeing anything major in your images. You are not a carbon fibre expert. Take it to a bike shop.It's 100% damaged, they weren't there from the start and rings around a carbonfork is not good. My fault probably yes.
The thing with the bike and the manufactur is that they ****** up with the bike, I can't even lower my seatpost because a big bump insid the bump and many more small mistakes from them. Otherwise I would already have ordered a new from them. But this is my fault. Sucks
I do I do, that much have I understood after looking on countless videos and tutorials. This is from riding a loose headset without crown? The dustcap have made the marks.Daft question, when you tighten the steerer nut on the top your doing it when the two bolts on the stem are loose so the stem can slid down and compress?
I learn every day, thing is I am a poor dude who cycled for the fun off it, I hate all the mechanical things . And it have been a struggle to learn all the things you need to know if you want to cycle, but this is apparently not the same as learning how you put on a new tire... I can see that now.
