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 Shimano kit ensure every contact point is a joy to use throughout your ride.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. Our 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 BLK TEC carbon fibre cockpit components.
Gold STC represents the ORRO gold standard in ride quality with a competitive frameset weight and clean aesthetic. The geometry of our longest running model has been revised across a myriad of generations to create a bike which seamlessly balances speed with efficiency for endurance riding. The rider is perfectly positioned to allow for full focus on the ride ahead while the Sigmatex engineered spread tow carbon frame offers ride dampening qualities for unrivalled comfort. Our unique relationship with Sigmatex, who are a UK based carbon composite specialist, allows us to have an intrinsically detailed and supportive design ethic so we can produce the best results. The STC material was chosen for its combination of low weight and high stiffness allowing us to optimise certain areas of the frame for the ride characteristics that we wish to promote. This has given us a future classic in the Gold STC - a bike of climbing category weight with all the comfort and efficiency required to take on any endurance challenge you can point it at.
After years of product conceptualisation and design development we welcome the first ORRO electric bike into their Terra family. Early in the design process the ORRO bike team homed in on gravel riding as the basis for electric development. The aim was to enable everyday cyclists with the ability to take on more mileage and make it easier to tackle tough off-road climbs, such as those in the native South Downs testing ground. Terra E marks a considered entry from ORRO into the empowering world of lightweight electrically assisted bikes.Terra E has an integrated design and user experience. Each of the five colour coded power modes are easily selected while riding using a backlit button on the top tube. The clean lines of this lightweight carbon fibre gravel bike belie its electrified nature. A svelte down tube hides the 250-Wh battery of the FSA System HM1. And, with an optional range extender cell which is carried in a bottle cage, the capacity for power can be doubled. A mobile application wirelessly interacts with the system, adding the ability for riders to review battery performance and customise the settings.In developing a hub motor driven e-bike ORRO have been able to keep the horizontal distance between the pedals, known as 'Q Factor', the same as typical non-electric bikes. This gives Terra E a riding stance and pedalling characteristics that will feel familiar to all cyclists. The frame is designed from the ground up for System HM1 motor and battery units. These components can deliver a maximum 42Nm of torque and a range of around 50 miles. Integrated torque and speed sensors provide natural feeling assistance across each power setting. Complete system weight is 3.98Kg.
The Gold Evo 105 has been designed as a comfortable long distance endurance bike capable of punchy hill climbing when the need arises. This specification is ideal for the sportive rider looking for the last word in efficiency at a competitive price. Evo specification bikes get the same proven geometry and frame features as their counterpart top of the range STC models. The frame manufacturing process employs our own custom layup of 3 different types of unidirectional carbon fibre material to provide an ideal blend of stiffness and comfort.The predecessor to the Gold Evo, the Pyro Evo was named as a Finalist in the road.cc Sportive and Endurance Bike of the Year 2019/20Featuring a full 105 groupset with the low maintenance consistency of hydraulic disc brakes to ensure power and control are at your fingertips on every descent. In order to achieve the right low end gearing for extended climbing efforts we specified a compact chainset paired with an 11-30T cassette. This combination offers a highly effective ratio of gears making it much easier to completely conquer hills of considerable elevation while maintaining a healthy pedalling cadence for smooth riding. Having lower gears to reach for preserves precious calories allowing you to remain in the saddle longer, this is perfect for the all-day rides we designed the Gold Evo to take on.
