Another thing to consider is what you intend to carry to and from work and how you want to do it, ie. a backpack or a bike rack. As an example, I have a mountain bike I commute on right now and my options for a rack are limited and frankly not optimal, as opposed to those road bikes that have connection points on the frame for a rack. Because of the heat we have here in Phoenix and because of my preferences, a backpack is out of the question. For some folks a backpack is just fine and if you are one of those, rack mounting is not an issue.
