Crank fell off on ride. WWYD?

[Julibird]

edit to add that I discussed this thread w/ my mechanic and he said it very well could be a problem w/the crank, and he wouldn't trust it either. BUT you shouldn't have to pay for an all new crank. THO if you want to upgrade, then yeah you should have to bear the cost of the upgrade. basically the lbs owner can call the manu and get a replacement crank for free, but to buy the upgrade HE has to put out $$ in the cost of the new crank. And it's not like the manu will refund him money, so yeah... expect to pay at least cost on the new set.

Thank you! This is precisely the kind of guidance I was hoping to find. So helpful!
