I bought my Fuji from Performance. Haven't had any problems with the bike or the service. They swapped out my brifters for free, installed Kool Stops for free, and are extraordinarily patient and nice. The people at the Naperville one and the Lincoln Park store are both great (haven't been to Northbrook one). To be honest, the people at Performance are nicer and friendlier than those I've encountered at a lot of other Chicago bike shops - Upgrade Cycle, Cycle Smithy, On the Route, etc. And the lady at Rapid Transit was so eager to make a sale, she talked my ear off and wouldn't let me leave. And I won't even get started on Village....
