I have a new bike (180 miles on it so far) and over the last 80 miles or so I have noticed that when I hit a bump or shift excess weight to the handlebars, the front end makes a creaking noise. It is more noticeable at higher speeds which is probably due to more force.

I have carbon a fork. I am not sure if it is the fork making the noise, the headset, or the stem/bars. Is this something I should be concerned about or is this normal?
