Yesterday I tested the 2006 Tirreno Razza 2000. It is full carbon bike with Ultegra components. The price is $1,600. I'm shopping at Performance. My first bike was a Firenze Lightspeed, then I went to Cannondale CAAD8. Now looking for a full carbon due to needing more of a comfort ride. Any suggestions, recommendation on this Tirreno bike? Thanks, Freddie
