Pics or it didn't happen!

I think you'll be able to commute o it, depending on the distance. Put some 28 mm tires on it, reduce the tire pressure a bit, and you'll be good to go!

I commute about 70-100 miles (sometimes I take the long route home) per week (when it's not snowing) on a steel framed 2010 Jamis Aurora Elite. I don't know if that constitutes heavy duty commuting, I'd probably go up to 15 miles each way now pretty happily. I just bought a new 2011 Giant TCR Advanced 2 for 'training' rides (I don't have any plans to enter any real races). I love my Aurora Elite for commuting, but it's pretty heavy (about 35 lbs), it's a triple, and it's a 11-34 which is nice when I'm going up hill, in to the wind with another 40-50 lbs of stuff in my panniers, but it's lousy for doing group rides on, cause I could never find the right gear.
