Hi,

After my first test ride and a check of my bike, headset am so on, I noticed this mark about 1cm on the top of the steerer tube, at the stem level.
Is that damaged or safe to keep riding with that ?
I wonder if the carbon quality is not involved in that change and suspect the stem pressure might have caused it.
I am thinking to go to the LBS to make sure it is safe. No marks or cracks further below.


Thanks for your advice.

John
