17-18 lbs or so. I'm not sure. But, I travel as light as possible. I store most of my stuff at work, like clothes and shoes. I also have a drawer full of canned sardines and salmon, some bread, fruit, a bunch of oatmeal and some nuts. I bring a lot of that stuff in on days that I drive.
My bike is bare. No panniers, rack or aerobars, for example. It's just the basic road bike, with a small saddle bag and a canvas frame bag which I use to carry some of the basics like more food or fresh clothes (I bring in and take home one or two items per ride) when I am not driving that week.
