Unfortunately so.
Check with
www.biketraffic.org for information about cycling in Chicago. Also, check out Yojimbo's Garage over on North Clybourn. Marcus is cool, and he can help you out. And check out his website:
http://www.yojimbosgarage.com. If you click on the picture, you'll enter his website, and when you see the links title on the top of the page, if you click on that, you get some info on some of the cycling culture in Chicago.
