I found that my steering tube on my fork is not perfectly round. It is different in diameter by about 0.6mm from one measurement to the measurement 90 degrees from the previous. I believe I did this when I over tightened the stem without a spacer between the headset cap and the stem. Is there a way I can correct this or is my only option a new steering tube? Btw, its a Fox F100 RL 32, non tapered steering tube.
