So you think the build was of an acceptable standard then ?
I don't know the shop (only looked at the website) and I haven't inspected the bike, but from what I've read I would say that he "saw you coming" and/or is out of his depth with high-end kit.
However you did take the bike out of the shop with the levers in that position, and taped the bars yourself with them there, and posted about what a great ride it was!
If I were you I'd book into Surosa (or similar ie someone who knows how to build expensive bikes) for a service and proper bike fitting. Then you'll be confident that everything is safely screwed together, and that the bike is properly set up for your size and style of riding.
I know it's a bit more expense, but in the scheme of things would be money well spent. You've got what should be a great bike there and I know how much you'll enjoy it!
Another week or so getting it professionally fettled and you'll be sorted - and it might have stopped raining by then!!
