If this fork was brought in by a customer I would suggest they don't continue to ride it any longer. This is a bonded together AL crown (and blades) to a steel steerer. The crown race "shoulder" has cracked and broken off partially around the steerer. When AL starts to crack wise ones take note
Sure one could make a claim that the broken off portion is only supporting the crown race. As in a non structural failure. Still I'd hate to have to say under oath that I knew the fork had cracked yet I felt it was going to be safe after "repairing" using rather unconventional methods.
I do wonder what was the cause of the broken "shoulder". Was it riding with a loose headset? Was it from some impact long before? Was it from poor initial fitting/bonding? Without this backround I don't see how I can suggest using this fork to keep one's face off the pavement.
Your opinion may differ. Andy
