Need your opinions on something. After this incident, I'm thinking about getting a second bike as back up. Found a 2009 Cervelo S1 in my size. It looks like bone stock with Ultegra SL. I'm going to see it on Monday. I'm sure it'll ride very different than my BMC roadracer. For that model year, what is a reasonable price for that bike? (assuming that it's in excellent shape)
