As an employee here at CC I have access to a lot of bikes. I don't buy for myself just any bike, it has to be special. The Oltre XR4 is that good. As a racer in my late (very late) 40's I have to be careful. I want a bike that is fast, stiff, race geometry, but my back, shoulders and whole body don't take 4 or 5 hours in the saddle like the did when I was 25, at least as far as I can remember anyway. The XR4 is stiff and efficient, it's an aero frame bit it can climb, you can stand up and rock that bike all over. You can ride it all day, the carbon layup technique really does make a difference, I can feel it, that's a major reason I went and bought one. Those are the important things, the not important things, but really are actually important, Bianchi's are gorgeous. Thumbs up on the the Oltre XR4. If you're looking for an overall fantastic bike and ready to treat yourself give it a good look. I upgraded to Dura Ace 9170 and 454 wheels. I wanted to drop a few grams being the reason behind that. If you've ridden the new Ultegra Di2 it's phenomenal, it's bullet proof, and very easy to use and maintain. There is a frame build option if you wanted to do anything different from this specific build I can help you out on that.
