In developing the Cento10Air, the 110-year-old Italian frame maker Wilier Trestina decided to go with a redesign to achieve a more aerodynamic frame that boasted a lighter weight than the previous model and gave riders all day comfort. We are riding the Wilier Cento10Air around Northern Italy to put the bike through its paces but first here is a first look at the striking red Italian race machine equipped with Shimano Di2 Ultegra.

To make the frame more aerodynamic, Wilier used Kamm Tail NACA airfoil shapes on most parts of the bike including the seat tube, seat post and down tube. The frame has clean internal routing for the Shimano Ultegra Di2 shifters. The bike we are riding has a 54/39T chainring and 11-28 sprocket cassette. Flat mount Ultegra brakes provide sure and confident braking even on the steepest and most technical descents. It also provides the clearance for 28 mm tires.

The fork and seat stays have both been moved away from the wheel rim, a feature intended to reduce air turbulence as it passes through the narrow space. The seat stays have also been lowered for improved aero performance and compliance in the backend. The aero carbon seat post is made by Ritchey.

The integrated Alabarda one piece handlebar and stem has a striking aerodynamic profile that allows Wilier to internally route all the cables. Apart from looking really good, it provides a really clean setup with only the brake cables peeking out from the bottom of the bar. The electronic shifter cables go hidden until coming out of the frame hear the derailleurs. The handlebar has a – 10 degree angle in order to better cut the wind and lower the front end to allowing riding in an aggressive position. The bar is available in six options.

Not a lightweight climbing frame but that doesn’t stop it when the road tilts upwards

The frame has also been trimmed down weighing a full 200 g lighter than the previous generation Cento1Air to push the scale to 990 g. Not featherweight but very respectable for an aero frame. Capping the built off are Mavic Cosmo Elite wheels and Mavic Ksyrium 25 mm tires.
