Ok, great news! Went to a respected shop and got a clean bill of health. The shop speculates
that the long stem was jammed downward and caused a small fracture; however they didn't feel like it was a significant issue
Thanks to everyone for their advice..
Also confirmed that the rest of the bike was in new condition and had < 50 miles as reported by the seller.
Monkey off the back
if you bought the bike from them I would expect that they would think it is a significant issue.
As others just said....its not a matter if it will fail; but when.
Besides, you said the shop speculated. Its not fact and I would take that speculation with a pinch of salt.
You might not regret demanding that refund from that guy you bought the slice off, but when you're in a serious accident who's to blame when countless here have given you advice what to do!
