I had the same question myself in 2011 when I decided it was time to upgrade from my 27 year old Miayta. I decided on a Jamis Quest, both for its steel frame and its "endurance" geometry. I wasn't looking for a grail bike, but one that would be comfortable for lots of miles. I have been extremely happy with it. The only thing I have changed from stock is to add a Brooks B17 saddle.
