There is a Performance store in Northbrook. I travel and found the folks to be fairly nice for northerners.....just kidding. Might be a good place to find a deal on some of the bikes they stock. They also have a service department. Once again, I only found the place by mistake, so when traveling to Chicago, I will stop and see what I can find. All of the guys working in the shop have always been nice to me. They must of figured I was a foreigner (from Kentucky).
