The story of the Wilier Cento1 SR is synonymous with the story of Wilier. The Cento1 reinvented the road bike, and reaffirmed Wilier's role in the Italian dominance of the peloton. Now, the Wilier Cento1 SR is your chance for a sample of modern history. Fully loaded with technological innovation, superior ride quality, and a blisteringly fast geometry, the Cento1 is the only legitimate choice for anyone looking for the best that Italy has to offer.Before the SR, little had been changed on the Cento1 (Chen-toe-uno) since Alessandro Ballan won the 2008 World Championships on his Cento1, and that's because Wilier got it right the first time. The Cento1 is most balanced frameset in the world. The tight-wheel base geometry is coupled with a comfortable, tapered head tube. The head tube's height acts as the stabilizer to an otherwise over-excited frame geometry. This juxtaposition creates a bike that remains comfortable over the long haul, but drops the hammer in the quick moments of an attack. In other words, the Cento1 is designed for the working professional -- conserve for a 100+ miles, and then bolt with 1k to go. The frame balance is further accentuated by the unmistakable chain and seatstays design. On the Cento1, these two sections of the frame are molded from one continuous piece of carbon fiber that flows seamlessly into the top tube. This design, along with an integrated seatmast and the oversized brake mount juncture, creates a rigid rear triangle that delivers direct power transfer with minimal energy dispersion. The design also works in your favor, much as it did for Alessandro Ballan, by creating predictable stability on high-velocity descents. To ensure rigidity, the Cento1 is constructed from a 60t Mitsubishi high-modulus carbon fiber. The 'T' in 60t refers to ton, as in it can withstand 60 tons of pressure per square millimeter. Wilier used strong carbon fiber, because the stronger the carbon, the less is needed. Thus, Wilier was able to strike the perfect balance between strength and weight. The innovative spirit of the Wilier doesn't stop at its materials. The SR incorporates the new BB386EVO bottom bracket system. Don't get aggravated at the thought of another 'new' bottom bracket design -- the proprietary design is compatible with all leading cranksets. Developed in cooperation with FSA, the BB386EVO is a competitor-dwarfing 86.5mm wide and has a diameter of 46mm. Wilier estimates that the new bottom bracket increases rigidity by 30%, and reduces power dispersion to almost zero.The Wilier Cento1 SR is available in the colors Matte Black and Red and in six sizes from X-Small to XX-Large.
