I have a Jamis Aurora, about 6 years old, which I used for commuting 34 miles round trip. It was excellent. I threw a pannier on it. Carried my work/gym clothes, also excellent for shopping, etc.
Then I tried touring with it. Needed to change gears, wheels, tires....
Now, it's also great for touring, but off the rack an excellent commuter, fun bike..
