Venturi Ultegra

Our specially designed aero disc road bike. With unbeatable low weight and stiffness, and utilising an aerodynamically optimised frame, the Venturi rewards you with real world speed. This is a bike that encourages you to ride fast but lets you cruise in comfort when you want to calm things down.

Optimised for 28C tyres, the Venturi fully realises the benefits of wider tyres on road bikes. Wider tyres allow lower pressure, improved grip and decreased rolling resistance. Importantly, they also allowed us to decrease free space between frame and wheels, improving the flow of air.

The Venturi is manufactured using spread tow carbon from UK manufacturer Sigmatex. This unique carbon fabric uses unidirectional spread tow tapes which allow for a greater number of fibres in a smaller space. Using this carbon results in a frame with lower weight, which boasts brilliant stiffness and comfort.

The check list of features includes a removable front derailleur hanger for 1x set ups, our proprietary hidden seat clamp, flat mount brakes, 12mm thru axles front and rear, routing for electronic and mechanical groupsets, an aero seat post, and tubeless compatible wheels as standard.
