Our brand new Venturi STC is an evolution of our much loved speed machine. We knew nothing had to be revolutionised with this aero bike so we have kept the geometry and handling that makes the Venturi so easy to ride and updated the frame and cockpit to make it even better. We now have a fully integrated cockpit on every model for improved front-end aero performance and a clean look.

Orro Venturi Ult Di2 SC55 med Tailor Made

Season:2025

Brand:Orro Bikes

Code:ORRVT4S817VSTE51

The Venturi is an aerodynamically optimised frame that rewards you with brilliant speed. This is a bike that encourages you to ride fast but lets you cruise in comfort when you want to calm things down. The Sella Italia, Visionand Shimano kit ensure every contact point is a joy to use throughout your ride.
The next generation of the Venturi STC has fully integrated cables through the bar and stem on every model. This has enhanced aerodynamic performance by reducing drag coefficient while emphasizing the clean lines and frame finish. Our integrated design is flexible so you can upgrade easily at a later date, or change to a completely different bar and stem set up depending on your needs. This model features a frame size specific Vision SMR alloy stem and a carbon handlebar.


Spread Tow Carbon
We manufactured the Venturi using spread tow carbon from the leading UK manufacturer, Sigmatex. This exquisite carbon fabric uses unidirectional spread tow tapes, allowing for a much larger number of fibres in a smaller space. As a result of this, we have been able to create a frame and fork that is exceptionally low in weight, while boasting brilliant stiffness and comfort.
WHY SPREAD TOW?
SigmaST is an innovative carbon fibre textile, increasingly used for its lightweight nature and improved mechanical performance when compared to traditional carbon textiles. It is 20% lighter than traditional carbon fabrics and has an excellent strength to weight ratio. This technology is highly advantageous in such industries where there is an increasing demand for strength and stiffness combined with low weight.
