There is no limit to technical innovation. Carbon fiber is pre-eminently the material used today to build bicycles and bicycle parts. But till today not all the characteristics of carbon fiber are being exploited and used. It is possible to obtain even more from carbon fiber and achieve results which are yet to be discovered. With its range for 2011, Guerciotti presents a new concept which will radically change carbon fiber working and the products that can be obtained: NO LIMIT CARBON ENGINEERING. This concept represents only the first element of a set of products which will revolutionize the cycle market. Crucial partnerships with companies producing carbon fibers for sectors of high technology and reliability (aerospace and Formula 1), a leading knowhow and the results obtained in racing events have lead to creating the first step of a series of products which will really have no limits. NO LIMIT CARBON ENGINEERING lays its foundations precisely on the characteristics of the composite materials. Carbon fiber contains all the necessary physical and mechanical characteristics to optimise the primary qualities which a racing bicycle frame should have: lightness, comfort, torsional stiffness and extreme responsiveness. Starting from this basic concept NO LIMIT CARBON ENGINEERING is a project which aims at realizing new products, by following the necessary technical prerequisites, among which the resistance in time, in order to ensure the maximum mechanical performance and valid results.

Everybody has defined the monocoque technology as the only possible solution to be able to obtain a frame with greater lightness and greater stiffness.
NO LIMIT CARBON ENGINEERING was however conceived to break these barriers and to move further. To obtain an increasingly lighter frame while ensuring greater safety and reliability. Weight has always represented the biggest limit of wrapped frames. Solutions of this type have always turned out to be heavier compared to monocoque frames of an equivalent range. The monocoque has always been considered by the market as the only solution for top of the range products. But this happened in the past. Now, with NO LIMIT CARBON ENGINEERING all this has become outdated and all the maximum characteristics that could be obtained from a monocoque frame can today be obtained with the wrapped frame technology and they are available to anyone with Eclipse.
Eclipse represents the main novelty of the 2011 range of Guerciotti, based on the priciples of NO LIMIT CARBON ENGINEERING: selection of the best raw material, innovative production technology, italian design and quality, strict tests and quality control.
NO LIMIT CARBON ENGINEERING was conceived in 2008, when Guerciotti got back to playing a leading role at the Tour of Italy with Gilberto Simoni. The challenge of directing it’s effort towards increasingly ambitious targets has helped Guerciotti in developing a series of projects of which the Simoni Replica of 2008 was only in it’s embryonic stage. Michele Scarponi was the last exceptional tester, who was really active in giving birth to the project and who developed it together with the engineers of Guerciotti. The modifications introduced to the Replica Team in the Tour of Italy Limited Edition version used by Michele show the effectiveness and reliability of this project.

With this new RAW MATERIAL QUALITY TESTING system, Guerciotti intends first of all to select the best materials available on the market using a quality search and study system, by selecting the perfect mix among the various fibers in order to obtain the best possible results for the intended use.

The NO LIMIT CARBON ENGINEERING project introduces an innovating wrapping system called LIGHTNESS WRAPPED CARBON TECHNOLOGY with which the positioning of carbon fiber skins assumes an essential role, as this is very important to give the frame its main mechanical characteristics. The skins are superimposed so as to orientate more filaments along the stress lines. In fact, by interweaving and superimposing carbon fiber skins it is possible to modify the mechanical efficiency of the structure and of some of its parts.
Appearance represents an important element. With this new wrapping system it is possible to obtain a frame which in aesthetically is like a monocoque, no longer showing any working marks. Such a remarkable appearance is the result of an arduous and methodical system,  completely hand made, combined with a particular and exclusive resin tapping process.

In the 2011 range Guerciotti introduces the CLS (Comfort-Lightness-Stiffness) CARBON DESIGN system, which represents the study of the best design to increase the efficiency of the frame in its more delicate and important parts. In fact, the fundamental elements of a top of the range frame are the riding comfort associated in any case to lightness and stiffness. The objective is to obtain the best ratio between these three constituents.
The particular design of the seat stays of the Eclipse and Eureka model was realized on the basis of the study aimed at giving comfort, lightness and stiffness.
The ribbing inside the chain stays of Eclipse serves to convey greater resistance to compression and traction to the sheath which renders a greater stiffness.

The new system of integrated drop-outs has been adopted for the new innovative Eclipse model.
The drop-outs are made in carbon fiber and they come out from the mould already integrated in the rear/chainstay. They are therefore not glued but fixed to the vertical tubes by wrapping. Small protection plates in anodized aluminium are mounted on the drop-outs and the right drop-out is used to mount the gear. Its particular fork shape reduces to the bare minimum the need for its replacement in case of fall. the replacement, in any case, is extremely simple.

Eclipse represents the first product issued from the new NO LIMIT CARBON ENGINEERING project. The weight and incredible stiffness of Eclipse has been made possible thanks to fundamental stratagems in the customizing technique of tubes and design.
The first prototypes of Eclipse had a weight of approximately 820 grams (painted frame). Studies and assessments carried out by using the CLS Carbon Design and the RAW MATERIAL QUALITY TESTING had persuaded us to choose different sections for some tubes and different carbon fibers in the more crucial zones which surely increased the weight but offered greater reliability. It is precisely the lightness / reliability and resistance problem,  which today represents one of the limits of the top of the range frames, that the NO LIMIT CARBON ENGINEERING project  is trying to overcome: increasingly lighter frames but with very high reliability and safety. The Carbon fiber used for Eclipse is Toray. The external fabric is 3K plain M49 produced by HEXCEL, the unidirectional inside is M46J produced by Advanced. This product comes from England and it represents the fiber which confers the greater part of the stiffness and solidity characteristics to the bottom bracket area.
The oblique tube is a combination of HR40 and M64 materials which confer a great torsion stiffness to the tube and a high resustance to impacts.
The HM46J fiber and of the UD fiber is used in the oblique tube to confer more resistance to torsion. In fact, based on the results of tests carried out in laboratories and in the field during racing events, when it is properly made, the oblique tube prevents the bothersome vibration effect at high speeds. The use of materials such as the M46J and the HM64 in the construction of the Eclipse allow to obtain very satisfactory results, the most important of which are  the resistance to traction (210 kg/sqmm)  and the resistance to compression (72,5 kg/sqmm). The use of these fibres to manufacture these tubes enables mechanical resistance to traction values which  can be compared to those of a steel tube. By using them, besides having a considerable stiffness, the frame also becomes more resistant to impacts and to heavy stress. All this is obtained by pressure, during firing, at approximately 6 bar, with a consequent extraction of excess resin such as to increase the percentage of fiber in the compound.

In the 2011 range, Guerciotti  reproposes the model with which the Company reappeared on tiptoes in professional circuit with the LPR Team and with which today it intends to dominate the international scene of professional bicycle racing. A new era for the Guerciotti Company which wishes  to consolidate its market position and which will direct all its efforts with determination towards becoming a market leader.
The objective of the Guerciotti engineers was to obtain a frame suitable for all types of consumers (like the team replica), but considerably lighter in weight and with a greater stiffness in the steering, bottom bracket and rear vertical areas.
To obtain the best possible product we have applied the FEA model (Five Forces Finite Element Analysis) to simulate the efforts and static tensions on each frame element. This helped in designing the frame and fork which fulfil the high requirements of torsional stiffness, resistance to impact, safety and lightness.
Moreover, in order to design the excellent dynamic performance of Eureka we have applied the measurement and dynamic analysis system (DMA) Somat 2100 to analyse the relation between speed and time during riding conditions.
Eureka is built by using carbon High Modulus HSM. By applying the RAW MATERIAL QUALITY TESTING the best carbon fibers available on the market have been used, among which the IM600 and the UM40. Eureka represents an excellent compromise between an important frame form and a good lightness, thanks to the concept of the CLS carbon design. We have therefore opted for the solution of placing only the internal cables inside the top tube so as not to increase still further the weight of the frame. With this option, we have tried to preserve an elegant appearance without neglecting the lightness feature, which always represents the most important aspect.
Even the design of the seat stays follow the same fundamental concepts  of NO LIMIT CARBON ENGINEERING, which gave birth to the Eclipse model.
