Orro Venturi STC 105 Di2 R800DB Road Bike (2023)

Built for speed, this road bike was created to be ridden fast with a fully custom ST carbon layup and a Shimano 105 Di2 electronic groupset. From front to back, Orro has ensured that its tube profiles cut through the air as effectively as possible, helped by a super clean front end and reduced gap between tyres and frame. With a super stiff bottom bracket and downtube, the Venturi STC transmits watts onto the road efficiently to eat up miles as fast as you’re able. Getting you into the best position out on the road, this model comes complete with size-specific components, the brand’s bespoke STC carbon fibre layup, and clearance for 28c tyres.

The Venturi STC is an evolution of the much-loved speed machine. Orro knew nothing had to be revolutionised with this bike so 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. It now has 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, FSA and Shimano kit ensure every contact point is a joy to use throughout your ride.

Integrated Cockpit

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. Orro’s 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 frame size-specific FSA ACR aluminium cockpit components.

Shimano 105 Di2 Groupset

Shimano 105, the world’s most popular groupset, has gone electric with Shimano’s Di2 tech. Shimano 105 has long been praised for its affordability and performance and the Di2 version is no different, bringing the speed and accuracy of electronic shifting to even more riders. It comes specified with a 50-34t compact chainset and 11-34t 12-speed cassette for flexibility both ascending and descending. Hydraulic disc brakes ensure power and control are always at your fingertips.

Venturi STC

If you like a fast bike with razor-sharp handling and a high degree of comfort then this is the bike for you. The headtube has also been modified to over-sized 1” ½ bearings top and bottom for added stiffness and to help facilitate the fully internal cables. All the key features from Orro’s first design remain; aero tubing with a fully custom ST Carbon layup for low weight and a high stiffness, 28c tyre optimisation for added comfort and decreased rolling resistance and flat mount disc brakes for serious stopping power.

Speed and Comfort

Optimising the Venturi for 28C tyres allows the rider to reap the benefits of wider tyres on a road bike. Some of these include the allowance of lower tyre pressure, running lower PSI improves comfort. Two other major factors are improved grip and decreased rolling resistance. If you, the rider is more comfortable then you can ride faster, for longer. Using 28c tyres has allowed Orro to reduce the space between the tyres and the frame smoothing airflow over the frame instead of creating turbulent air behind the tyre.

Custom Carbon Layup

Orro has extensively tested different carbon layups to make sure they have the best combination of speed and comfort on the Venturi. 3 different layups were designed and made into frames, then tested back to back. It’s this time and effort that make sure the Venturi is as fast as possible, all the time.
