I took my bike in for a tune up and when I picked it up the mechanic said he "fixed a creak" in my headset. I had never heard any creak.

The steering is now so tight I can put the bike in a stand and have the top tube at a 45 degree angle and the handlebars will stay set where ever they are.

Before they would have quickly flopped to the downhill side.

This seems wrong to me, but I have no real experience working on bikes.

Is this something I should be concerned with?
