Well, duh, after thinking about it, there's no such thing as 105 flat bar shifters, so that accounts for that one. It's just the rear derailer they could have kept as 105 and I don't know, but suspect, that the 105 derailer may not accomodate the 12/30 cassette. Maybe??? Anyway, I'm pretty sure the Tiagra will be fine as I'm an older fart and just ride for fun and fitness.
On a related, sad note, I got a call from the LBS yesterday and my 7.7 arrived with a bad scratch and broken cable mount under the top tube

They're going to have to return it and order me a new one so another week of waiting. Oh well. What'cha gonna do?
