2021 Venturi STC SRAM Red eTap AXS


Geometry Chart


Our brand new Venturi STC is an evolution of our much loved speed machine. We knew nothing had to be revolutionised with this 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 a bike that encourages you to ride fast but lets you cruise in comfort when you want to calm things down. The Prologo, BlkTec and Sram kit ensure every contact point is a joy to use throughout your ride. 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

Our updated Venturi is now fully integrated utilising the alloy FSA ACR system on our standard versions and customised BlkTec carbon bar & stem on all Tailor Made versions. We have designed this system to be flexible so you can upgrade the FSA ACR at a later date or change to a completely different system easily. Full front-end aero performance and a clean look were the goals here.
