The Wilier Twin Blade Frameset takes a unique approach to font-end aerodynamics and stability as the crowing touch on a fast ride.
 
That front end eschews the common fork crown for longer blades that reach past the crown up to the handlebars. This increases stiffness by nature of the wider blades and the fact that the handlebar is clamped in two places by what is the equivalent of two *0mm long stem clamps (which can be swapped for *0mm clamps). Steering is now easier and more precise, as there's less flex in the system. Of equal importance are the improved aerodynamics. By moving the fork blades away from the spinning wheel, there's less turbulence crowded around the spokes. And to make sure that airflow stays smooth, the legs are long front-to-rear, as long as *0mm at one point, to keep air moving with as little turbulence as possible. And if you glance at the seat stays, you'll see that they, too, have a wider stance, also to keep any turbulence coming off of them away from the turbulence created by the rear wheel.
 
Keeping with the aero theme, the bike has a narrow 1 1/8" steerer to secure the fork to the frame. The integrated brakes, which come with the frameset, are mounted behind the fork and under the chain stays. These are TRP linear-pull stoppers, and by being anchored to the frame, they respond quickly to s and have little flex; stiff braking when you need it.
 
Wilier's road racing heritage is very much in evidence in the rest of the frame. The **-ton carbon utilized is light and stiff. The geometry sports a **-degree seat angle and the seat post has a rail so the seat clamp can be positioned for laid-back or aggressive positioning and certainly can fall on the legal side of the UCI's position stipulations; figure this goes back to an effective **-degree angle and forward to an effective **-degree angle. The Twin Blade is stiff without being a board, thanks to short seat stays that allow for some vertical give.
 
Wilier also has a few design features you won't find anywhere else. Their Easy Adjust dropouts allow you to move the rear wheel fore or aft by 6mm, which can both fine-tune aerodynamics and ease of removal. The orbital front derailleur hanger allows you to change the pitch of the derailleur at the frame to find perfect shifting, or remove it entirely for less weight and better aerodynamics if you're using only one chain ring.
 
Wilier has chosen the Wilier BB*3 (aka BB*4) standard for this bike. On the plus side, no bearings are external; they're hidden away behind aero shaping. And if you're a Campagnolo fan, you won't need adapters to fit your cranks. If you prefer another brand, the adapters are easy to come by and everything remains internal.
 
Cabling runs internally, too. You can use either mechanical or electronic shifting with the internal routing. There is a mount for the battery on the underside of the down tube; if you want to run a battery internally as well, you can, though there's no internal spot specifically designed for it.
 
Fans of wide-rimmed wheels take note. Some, like the Zipp Firecrest series, are a tight fit between the chain stays.
