Well, that’s the thing. I spent a week trying to figure out how I could run into something large enough to cause a huge crash, without seeing it…
A woman saw the crash and stopped her car, took my iphone and called some people in my contacts list. There were also other cyclists who witnessed it. There was nothing to hit…the fork snapped. Front wheel is fine and true (Dura Ace carbon/aluminum clincher 7850.) After a week, it still had full pressure.
