2007 Colnago Extreme-C

The Extreme-C is an evolution of the C50 that was originally created as a lightweight prototype for the Rabobank riders in the Tour's mountain time trial up Alpe D’Huez in 2004. The frame is made using high-modulus carbon fiber tubes and compression moulded lugs from ATR Composites. ATR builds carbon race components for Aprilia, Ducati, Lamborghini, Maserati and Porsche.
