Crack in the head tube! Trek 600
This photo from before our tour shows the crack that I didn’t notice... it runs along the entire lower lug and as you can see wraps around to the front. I got in there with a dental pick type tool and it’s not like a deep or open crack, but it looks to me like the HT is done.
Posting for conformation and commiseration. I built this up for my sons and it saw a lot of great use over four or five years . My favorite and most challenging build with a mix of ultegra 9sp, flat bar, and rusty parts bin MTB mech. It was super light and ran great!
