Product Description
For the better part of a decade the road bike marketplace has been defined by a singular arms race: With each passing year carbon frames have gotten lighter and lighter to the point where sub-800g no longer astonishes. Sure, we're glad we're no longer racing on a 1250g frame, but likewise common sense tells us there are diminishing returns once you get below 900g. The cost, the flex, the paranoia about possible fragility: these are things we wouldn't mind sparing ourselves. We're smart enough to know that the goal is to ride faster for a given power output, and that at a certain point your focus shouldn't be on shedding grams of mass and instead should be on shedding grams of drag. CervAAlo built their powerhouse brand based on this principle. Ridley revitalized their brand along the same lines. And with the Imperiale you're seeing the same from Wilier, one of Italy's most-respected frame manufacturers.Wilier spent considerable time pondering aero issues in the development of their Cento Crono family of TT bikes. They consulted with aero mastermind John Cobb, and they've combined these lessons learned with details from the Cento1 to make their first-ever road frame specifically designed to maximize speed by minimizing drag.The aero priority of the Imperiale is made clear by the soft curvaceousness of the downtube. It's shaped with a modified beak to help clean the residual air coming off the rotation of your front wheel. And you'll notice the complex curves on the sides of the down tube. These add significant stiffness while helping guide the air over the sides of the tube toward the rear of the bike. The head tube forms a peak which helps lift the air up and away from your front wheel. There is a continuing compound curve along the sides of the headtube to also guide the air toward the rear of the frame.
