2007 Shanghai Cycle show - Catalogue 2007 Extreme-C

Colnago's all new for 2007 Extreme-Power is the most innovative bicycle in the Colnago range. The Extreme-Power was born to meet the demands of sprinters Alessandro Petacchi and Erik Zabel of Team Milram and three time World Champion Oscar Freire of Team Rabobank who all have a power output of 180 kg for each pedal stroke. Extreme-Power frames have special conical oversize down tube and top tube tubing, with a 38mm diameter head tube and 44mm bottom bracket. Inside these special butted Extreme-Power tubes are two unidirectional high modulus carbon fiber longitudinal reinforcement ribs that are 10mm long and 0,8mm thick. These internal reinforcements provide 30% more resistance to torsional stress than before, while the 35mm diameter seat tube accomodates a 31.6mm oversize seat post. The bottom bracket is in CNC Titanium to facilitate maintenance. Extreme-Power's rear chain stays are in Colnago's distinctive Leaf shaped form, with a new oval 17*35mm insert into the bottom bracket. Extreme-Power is available in 15 traditional sizes from 52 c\t to 65 c\t , 7 sloping sizes and the Extreme-Power can also be made in personalized custom sizes.

Extreme-C is a special Colnago that was originally created in 2004 as a limited prototype bicycle for Rabobank riders for the mountain TT up l'Alpe D’Huez in the Tour De France. Extremely light, yet solid and safe, Extreme-C is the perfect frame for riders who like the challenge of climbing. In 2005 and 2006, Rabobank rider Michael Rasmussen rode his Extreme-C to a stage win and the Maillot Pois of Best Climber at the Tour de France, while in September 2005, Rabobank's Denis Menchov won the Vuelta a Espana riding a Colnago Extreme-C. These two years of severe testing have shown just how strong, versatile and safe the Extreme-C is.

Created for long and hard mountain riding where every gram is important, the weight of the Extreme-Cis under 1.000 grams in a medium sloping size, but without compromising any safety and security. Extreme-C’s frame has been re-engineered step by step, using round carbon fiber tubing, the best shape for lightness and to increase stiffness, Colnago created new oversized, more rigid chain stays for the Extreme-C to increase power transmission for long, hard riding. The bottom bracket is in CNC Titanium to facilitate maintenance.
