Venturi STC 105 Description

Our brand new Venturi STC is an evolution of our much loved speed machine. We knew nothing had to be revolutionised with this Shimano 105 road 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.

The Venturi is an aerodynamically optimised frame that rewards you with brilliant speed. This is an aero bike that encourages you to ride fast but lets you cruise in comfort when you want to calm things down. The Prologo, FSA and Shimano 105 kit ensure every contact point is a joy to use throughout your ride.

Road.cc Review - "Orro has quite simply nailed it with the Venturi Ultegra Di2 Wind 400. Comfort, speed, handling, feedback and stiffness – you can have it all. And the icing on the cake? It's a looker too!"

Integrated Cockpit

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 frame size specific FSA ACR aluminium cockpit components.

Shimano 105 Di2 12-Speed

Shimano 105, the world’s most popular groupset, has gone electric with Shimano’s Di2 tech. Shimano 105 has long been praised for its affordability and performance and the Di2 version is no different, bringing the speed and accuracy of electronic gear shifting to even more riders. It comes specified with a 50-34t compact chainset and 11-34t 12-speed cassette for flexibility both ascending and descending. Hydraulic disc brakes ensure power and control are always at your fingertips. When it comes to Shimano 105 road bikes, the Venturi STC is up there with the best.

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.
