Just found this old thread and figured I'd check in with an update after four years of use. My Insight RS is still going along fine. In fact, I rode it to work this morning. I've got about 3500 miles on it now (swap it out with other bikes in my stable) and outside of my initial wheel issue mentioned above, I've only had to replace normal wear items including the brake pads, rear tire, chain a few times and the cassette once. Still haven't touched the adjustment screws on either deraileur since I unboxed it. Been a good purchase for me.
