I just received a photo of this "unknown" brand of bike with the following comment:
The bike was merely being ridden and had not been involved in a crash of any sort. The whole fork column came straight through the head tube without warning! As can be seen the aluminium cups that support the carbon have come away completely leaving the bare carbon. The head-tube has failed completely. Scary!
This story came from the inside, so all identify marks and names have been removed.
