The new Vertice frame was born from a need to create carbon fibre frames with custom geometry.

The most important tenet of traditional Italian frame manufacture is the placement of the individual characteristics of each athlete at the centre of the design. This is the main idea behind composing the frame of only three parts that allow us to make the frame to measure, but at the same time ensures high quality structural joins.

The head tube and down tube is very important with regard to stiffness and is made as one piece, as is the top tube and seat stays. The seat tube, bottom bracket and chainstays are also designed to be adjusted to the rider’s requirements whilst maintaining high stiffness.
• The down tube is created from a single mould already attached to the head tube, which is cut to the correct height for the rider. The layup of fibres and different rolling thicknesses optimizes the stiffness of the bike while maintaining a proper weight. The length of the down tube and head tube is custom and dependent on the requirements of the rider. The head tube has a small protuberance which helps smooth airflow past the rest of the frame.
• The top tube is characterized by a hole to allow the seat tube to pass through. The tube is uniquely shaped to allow for the custom placement of this hole (and so customise the seat angle). It is rounded at the front where it meets the head tube to increase stiffness. It morphs into a flattened shape around the seat post to increase the range for the custom seat post angle. Inside the top tube is space to hide an internally routed brake cable, which enhances the flowing shape of the frame.
• The frame has been designed to have an integrated seat mast, enhancing the structural rigidity. The unique flared shape in the middle of the post facing rearwards reduces the aerodynamic drag by reducing the amount of vortices created by the rear wheel. The conical section at the bottom stiffens the area most affected by the forces applied to the pedals. The faux cutout groove on the back of the seat tube is crucial to reduce the limit to the wheelbase and keep an easy removal for the rear wheel. There is a special housing for the front derailleur to ensure perfect installation and operation of each model.
• Rear dropouts: these are horizontally adjustable by 25 mm. This gives the user the opportunity to improve the stability of the bike by increasing the wheelbase, or in turn increases the reactivity if it is shortened. It also allows the possibility of a fixed gear conversion and aids short term repairs in the event of a broken wheel mid ride.

The choice of materials and processing

• Design of the frame: The frame design is performed using dedicated software (ProgettoTelaio that indicates the tube lengths and cutting angles as a function of the anthropometric measurements of the athlete. Defined quotas are chosen from the various components with different angles to assemble the frame. The software allows you to recreate reality in what will be the finished bike, ensuring that the positions of the components and of the supporting points of the athlete are correct to the completed frame.
• Composition of the frame: the frame is made up of different parts that come from moulds in standard measurements, but with various different angles. The frame is composed of the following moulds: a top tube/seatstay, seat mast, head/down tube and rear chainstays. Each of these components interfaced with each other create the custom frame. Subsequently, the tubes are cut to measure and milled in the interconnecting joins and then prepared for gluing.

• Bonding: The strength of a bond between two carbon tubes varies depending on the type of glue and carbon being used. Normally in addition to tubes being bonded together extra strips of carbon are attached to create a lug for each join. Improvements in the type of glue used made specifically for the carbon means that these extra lugs are no longer necessary on the Vertice. The use of specially milled tubes that provide a perfect fit and the right glue optimizes the stiffness of the frame whilst reducing weight.

• Carbon: carbon T700 is the perfect compromise to achieve a very strong and light frame. The thickness of the tubes varies along their length depending on the forces they are to experience, to optimise weight. The high modulus T700 carbon ensures excellent structural rigidity.

• Construction of the tubes: the tubes are made with special moulds inside where the carbon fibres are arranged following a precise mapping defined in the design phase. The position and the carbon lamination are crucial to ensure perfect standards of quality. The manual work on the composite must follow a precise protocol, always the same for every single piece subsequent to the being placed in the oven. This allows the correct polymerization in the oven with the aid of nitrogen controlled pressure on both the inside and outside of the tubes. The catalysis of the resins use of special release agents are indispensable for the good surface quality, but above all avoids the unnecessary excess resins to the structure.
