Wilier

Cento10PRO Disc Brake Road Frameset

Only a handful of framesets tug at an Italophile's heartstrings quite like the ones that roll out of the Wilier Triestina factory. It's a brand rich in history and deep with palmarès and continues to influence the shape of modern bikes we currently see in the peloton. By continually evolving its frameset using the latest materials and frame design, Wilier is able to reduce wattage expenditure through increased aerodynamics and lighter weight, building more responsive and efficient framesets. This is alive and well on this Cento10PRO Disc Road Frameset. It's Wilier's evolution of the Cento10AIR, a frameset that celebrated the brand's 110th birthday, and instead of a radical redesign, it focuses on improving the frame's torsional stiffness to the tune of 6%.

With just a handful of ride on the Cento10PRO, it's proving to be one of our favorite aerodynamic disc racing framesets, and even with all of the wind-cheating qualities, it doesn't detract from the fact that the Cento10PRO is really an excellent all-arounder too. Wilier specifically developed the tube shapes based on NACA low-speed algorithms, and Kamm theory in particular, which is responsible for the truncated trailing edges that we've come to see on many popular modern aero bikes over the past 5 or so years. The benefits of the flattened back are numerous, namely dropping weight while improving aerodynamics and increasing torsional stiffness. For the fork, a greater gap between the blades and the wheel, afforded by relocating the brake caliper from the fork crown to the backside of the non-driveside leg, greatly reduces turbulence, thus smoothing the airflow, while also providing powerful, and well-modulating braking.

Another frameset exclusive is the included custom carbon monocoque seatpost from Ritchey with 22mm of setback. This post works in conjunction with the frame to help reduce road vibrations and provide a more comfortable ride. The shape is unique as it has to fit inside the aero seatube and is developed to reduce turbulence as air passes by. Anchoring the post in the seatube is a sleek seatpost clamp expander sitting stealthily at the toptube/seattube junction shielding it from the wind. The Alabarda integrated aerobar also needs a mention. It's specifically designed to hide all of the cable and housing, with this disc brake version. We're no strangers to seeing the bars get wider as the stem gets longer on integrated setups but Wilier takes this one step further by ingeniously increasing the reach and drop when the width and length increase too.

When looking to construct a great all-around frame, one that's lightweight and responsive to every pedaling effort and bend in the road, you've gotta start with the right materials. For the Cento10PRO, Wilier relies on 60t Mitsubishi high-modulus carbon fiber for lateral stiffness at the frame and fork. The 'T' in 60t refers to ton, as in it can withstand 60 tons of pressure per square millimeter. 60t is incredibly hard to work with and only a few builders possess the experience and skills necessary for proper construction. The end result, however, is well worth it as it allows Willier to customize ride feel while still building a frame that's easy on the scale.

The Cento10PRO Disc gets a beefy bottom bracket area, helping transfer power for lightning quick attacks and sprints. The PressFit BB86 bottom bracket allows a cup with bearings to press into a shell that spans 86.5mm wide, improving stiffness over typical shells of 68mm width by increasing the real estate that the downtube can attach to the BB shell and allows more space between the chainstays so the frame can accommodate up to 30mm wide rubber.
