The new updated 2024 Venturi STC Ultegra Di2 ZIPP EDITION road bike designed and built in the UK 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 Deda, Vision and Shimano kit ensure every contact point is a joy to use throughout your ride.
