They used 5.2 Madones when we went. They were only slightly used and in excellent condition. I believe they were current year, and they turn them over every year or every other year - I forget. Sizing is better then most bike shops. The first day they have lunch and a bike fit. Before the trip you gave them your frame size, so your bike is ready to go the first day. They have about every stem size available, and set you up on a trainer to get a rough fit. I wanted a bigger frame the second day and they were able to get to the warehouse and swap it out for me no problem. I'm guessing your bikes will be Ultegra.
