Comfort engineered. Fit Dialled. Speed refined.

The Venturi Tri is an entirely new proposition from ORRO bikes for the Triathlon and Time Trial market. It takes the most aerodynamic elements from the proven Venturi road bike line and amplifies them with devastating results. 

Compliance and stiffness have been meticulously localised to the requisite areas across the frameset with UK engineered Sigmatex Spread Tow Carbon fibre; a material that ORRO have exclusive use of within the bicycle industry.

Bike fit is enhanced with adjustable specialist components. The areodynamically profiled seatpost features a saddle clamp that slides on rails. Profile Design supply the control centre which features a wide range of angle and length adjustment.  

Ensuring an areodynamic rider poition can be adopted easily assits in the speed of Venturi Tri but it's only half of the story. The frame and fork have been optimsed to capatalise on these gains with rouded leading edges and extended flat profiles to smooth airflow.
