My fixie was stolen a few weeks ago, so now i am looking for something to fill the void in my life. I'm currently in Wisconsin on a road trip with my girlfriend. We are headed to chicago tomorrow to watch her sister give a presentation at Northwestern. So we will be in that region of Chicago and also in the wrigley field area for a baseball game. Next we are headed for Madison and Minneapolis.

Would any locals of these fine midwestern cities like to recommend some bike shops?
