ZX1 – AERO INSPIRED FOR SPEED
The Vitus ZX1 is back, aero inspired, for maximum speed and efficiency.
Back in 1991 Vitus introduced the original ZX1 model. It was one of a number of pioneering launches for Vitus, bringing the first one piece carbon moncoque frame to market. This new manufacturing method allowed Vitus to push the aerodynamic boundaries of the ZX1 design, creating a truly unique bike.
The all new ZX1 is engineered for the demands of the modern road racer. It blends the benefits of a lightweight and comfortable race bike with the speed advantage of an aero profile.
Whilst not following traditional aerofoil profiles, as bikes are different to planes, the ZX1 utilises Kammtail tube profiles, where the trailing edge of the tube is squared off. The Kammtail has been proven to enhance comfort, whilst maintaining lightweight and stiffness. It also offers increased cross wind stability, without sacrificing the aerodynamics of teardrop wing style designs.
An asymmetric and oversized bottom bracket helps to maximise drive, and overall lateral stiffness. With the use of different layups we have a balanced power transfer on the drive and non-drive sides of the bike while under pedalling load.
Disc brakes keep the air flow clean around the import areas around rims and tyres, and compliment the aesthetics of the frame. Using 12mm bolt through axles to give a direct and connected feel to the steering, and a stable and efficient power delivery.
The ZX1 is built for speed. It’s ready to race, whether that’s in the pro peloton or out blitzing your friends on your favourite routes and sections.
