First, in the last two years I've put some miles on four different bikes.

20 year old Bianci mountain bike, average 12-13 mph
38 year old Schwinn 10 speed, average 12-13 mph
09 Diamdback Edgewood, average 12-13 mph (recently given to my father)
09 Raleigh Clubman, average 12-13 mph

So I'm not going to go very fast on any bike I get. I just want one that is comfortable to spend time in the saddle. The most comfortable of the bikes I currently have is the Schwinn, and that is because I like an upright position and put a set of Nitto Promenade bars on it. but the frame is a little on the small side.

When I talked with my LBS about what I wanted, 32-35 mm tires, room for fenders and kickstand, the ability to mount a rack, and no suspension fork or seatpost he first recommended a Surly Crosscheck but when I said that was really pushing my budget he showed me the Globe Vienna 2. We've already agreed that whatever bike I purchase I will be providing the bars and any required brake levers and shifters since I want the swept back bars.

Also, if I get the Vienna I will probably have them replace the rear rim at the time of purchase since I was told it is a single wall and I'm not sure if I would trust my 250 lbs to that.

My two questions are; Any idea on the general quality of the Vienna? and How would it work for longer rides like centuries?
