Apparently, these frames are a touch different in carbon and layup than stock. The BB is the same but, a few other places are different such as the HT area and areas of the main triangle. In addition, I was told that they cured these longer. I'll get the details and edit later. IIRC these frames are part of or left over from some training bikes for the Nippo-Vini Fantini team. Either we are piggy backing or taking leftovers...IDK?Gosh Idol's are sexy. Thanks for the pic. Have you ridden it yet? My impression was the stack height was pretty high in the size I wanted, and I would't have been able to go low enough to get my stack and reach numbers. How does it ride? I've read some review stating that it is not as stiff or responsive as hoped. Leaning slightly towards endurance type performance. No doubt a beautiful bike though. What are your impressions?
