Road racing carbon frame Duratec PHANTOM made of the strongest fibre in the world!
Toray® T1100. Granoc. Nanoalloy®. The best high-strength and high-modularity fibres laminated with the best resin. The combination of such high-quality materials combined with the technically fine-tuned design of the frame and brand new production technology has allowed us to create a wholly unique monocoque manufactured from a single piece with no joins.
Thanks to the joint-free design and continuous fitting of fibre, the Phantom utilises the maximum mechanical properties of the materials and achieves "miraculous" values for the rider: Weight of just 760 grams in size 57cm, torsional headtube stiffness 143Nm/°/kg, pedalling stiffness excellent 68N/mm. Put in layman's terms - a rocket, a bullet,... a professional racing machine readied for your very best performances.
Where are the benefits?
Made in a single piece - OnePiece Technology - 100% monocoque
AFCF fibre fitting technology
The arrangement of individual pieces and direction of fibre fitting has an impact on the resultant mechanical and handling properties. AFCF technology takes into account the design solution of the frame during the plan for fitting of the individual fibres. The aim is to ensure that in the places of the greatest stress the fibre is uninterrupted, so its mechanical properties are utilised to the full. In this way we attain limit parameters amongst rigidity, strength and weight of the monocoque.
|100% carbon fibre
The frame is made without a single metal component, and it contains 100% carbon fibres; the design solution makes it possible to fit the bearings directly into the frame (headset and bottom bracket). In the places most subject to wear we have used 3K Twill fibre and 1K fabric, which protect the lower layers of high-rigidity and high-strength fibres from being pulled out.
High torsional rigidity
The high strength and high modulus fibers embedded in nanoalloy resin with a technically perfect design solution achieves the highest possible strength parameters at very low weight. Torsional headtube stiffness of 143Nm/deg/kg and torsional stiffness near bottom bracket 68N/mm offers nearly 100% transmission of energy expended to acceleration.
Technical benefits of frame
For the Phantom frame we have selected top-class Japanese material with the best technical parameters. Together the processing of the fibres, production technology and design of the frame create a technical gem which we do not hesitate to describe as an assault weapon, both for hard ascents and sprints to the finishing line.
AFCF is an acronym for Accurately Fitted Continuous Fibre. This is a manufacturing technology for the production of composite monocoques which was developed in Duratec.
Each composite layer and its individual fibres are placed exactly at the desired directions. This is done without any deformations, wraping and deviations - the exact structure is therefore defined !
The arrangement of individual plies and direction of fibre fitting have an impact on the resultant handling and mechanical properties. AFCF fibre fitting technology fits the fibre in such a way that it is uninterrupted at the points of greatest stress. In this way we make maximum use of the fibre's properties.

The precision and technological readiness of production is so advanced that the resultant products made using OnePiece technology are of very high quality and have a precision down to hundredths of a millimetre. Not only the technology, but also the knowledge of how to work with carbon and experience of the last 20 years with this material has allowed us to prepare the head tube and bottom bracket of the frame so that the bearings are fitted directly into the frame with the required design precision. In the parts subject to extreme stress, such as the head and bottom bracket of the frame where the bearings are fitted, the more resilient fibre 3K Twill is used for reinforcement. The layout of the actual fibres is designed for the entire length of the frame, i.e., from the head via the bottom bracket, right up to the actual dropout … A monolithic frame construction is the optimal solution, and not only in cycling.
Not only the head tube but also the other parts of the frame have a round cross-section, because according to the basic rules of mechanics round cross-sections offer the greatest strength and rigidity at the lowest weight.
The optimisation of the Phantom monocoque was calculated using Hyperworks software. The aim was to plan the direction of carbon fibres and layout of the pieces, including wall thickness, in such a way that the designer-designated criteria were met. One of the conditions is a rider weight limit of 115 kg. During calculation using the FEM analysis we used several model situation simulating, amongst other things, critical loading such as full weight on the pedals when jumping on the bike or a collision during an accident. Naturally during the calculation we adhered to European standard EN 14781 designating handling and safety criteria. The low frame weight is achieved primarily by the variable but precisely defined thickness of the monocoque wall using carbon fibre processing technology.
The detail of the seat endpiece is one of the technically refined elements of the frame - but at the same time an element highly characteristic in design terms - which does not have a conventional seatpost clamp. The locking device is concealed in the seat tube and sealed with a cover. In addition to this optically identical frame element, we can also find other hidden details, such as the integrated loop for cable in the case of use of a mechanical set or chain catcher, where the designer really went to town with its form and functionality. But the details make the whole! In addition to design, the practical significance is underlined.
