Orro Venturi STC Ultegra Di2 SC 55 Carbon Road Bike - 2024

The brand new Venturi STC is an evolution of the much loved speed machine. Orro knew nothing had to be revolutionised with this aero bike so they 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.

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, Vision and Shimano kit ensure every contact point is a joy to use throughout your ride.

Uncomprimising Specification

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.

Orro 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, Orro have been able to create a frame and fork that is exceptionally low in weight, while boasting brilliant stiffness and comfort.

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.
