I'm back with more suspect cracks, this time it's an aluminum fork. The fork is from a Klein Stage. I've heard that aluminum forks should be avoided all together. I'm looking to sell this frame and fork but wanted to hear some opinions on these cracks before I did so. I can see a faint line that runs the circumfrance of the fork tubing under the paint along the same line other than where the paint is cracked. Wasn't sure if this had to do with the way these were constructed. Thank you for any assistance.
