The Colnago C64 Disc represents the evolution of the C60 Disc. The frame uses completely renewed materials, but is built by hand with the same techniques as the flagship of the Cambiago factory.
Colnago C64 Disc: completely handmade, tailor-made, in Italy, is the result of more than two years of research but also a child of the company's history, full of successes and innovations since 1954. The tubes and conjunctions of the C64 are made with the best carbon fiber, to produce a unique frame in the world that can not be compared to anyone else. All the knowledge and experience of Ernesto Colnago is contained in the C64 design.
The fork of the C64 has been completely redesigned, with an outer rib that gives the athlete more comfort but also increases the driving qualities (lateral stiffness). To increase stiffness and strength, a special rib was created inside the steering tube, co-laminated with a threaded aluminum insert that actually replaces the traditional expander. The C64 disc fork is made with a special C / D shape to allow the complete passage of the hydraulic pipes inside the stem, for a total cleaning of the lines. The front through pin, also 12 mm as for the C60 disc, is now a hexagonal threaded type, for the maximum weight reduction of the system. Weighing just 355 g, with the same shape as the disc version, the traditional brake fork accommodates the pivots for direct-mount brakes, a choice necessary to provide the space required for the use of large tires. The length of the fork has been increased by 5mm, a stratagem that has made it possible to create a hollow fork head, reducing the weight but maintaining the same rigidity and performance of the fork of the C60. The dropouts are now carbon fiber, made with a process similar to metal forging.
Although it retains the same shape as the equivalent C60 conjunction, the C64 steering tube is made with a new technology that has made it possible to reduce the thickness and therefore the weight. The shape has also been revised in the central part, with the addition of a pronounced rib to increase lateral stiffness. As with the rest of the frame, the surface finish is now in uni directional carbon instead of 3k for a further weight reduction.
Based on the experience gained with the concept steering gear, the technology has also been transferred to the C64 model. The upper part of the steering has been revised, it is now made of a special polymer composed of carbon fiber, nylon and elastomer. This feature offers an added ability to dampen road vibrations, improving driving characteristics and comfort.
Starting from the stellar shape of the C60 down tube, we have revised the lower part, now of slightly reduced width. This choice made it possible to more effectively balance the stiffness of the central area of the frame. To further increase torsional rigidity and maximize component integration, the down tube has a lowered area near the bottle holder. Although the C64 is not a chassis born with aerodynamic ambitions, this feature provides a clear advantage over a traditional solution. The cable clamp for the mechanical assemblies is now placed on the oblique tube in the area close to the steering and obtained from the mold.
Probably the most obvious difference between C60 and C64 is represented by the seat tube, which in this last model merges with the saddle joining to form a single monocoque piece. This feature increases the rigidity of the frame, while maintaining the low weight. Always visible in this particular is the grafting of the high rear sheaths, no longer rectilinear but with a conical shape, to increase the bonding force and therefore the overall rigidity.
The saddle knot is extremely clean on this model, thanks to the completely hidden and structurally integrated seat clamping system. Instead of a vertical insertion system like on V2 and concept, the C64 has a single lower draft wedge. The weight reduction is about 15 g and the wedge contact area with the frame is reinforced thanks to an aluminum core co-molded together with the carbon.
Based on the shape of the V1-r seat post, it offers a slight aerodynamic gain but above all increases the vertical absorption of the roughness, compared with the previous round tube with a diameter of 31.6 mm. The standard seat post has an offset of 15 mm, while versions of 0 mm and 30 mm are available aftermarket.
Designed around our proven TF 82.5, the pressfit standard with removable caps, the central movement joint is now more complex than ever. The cable guide, typically a screwed plastic detail, is now printed directly in carbon, for maximum weight savings and the widest possible radius for the best shifting performance. Another small detail is the hexagonal shape on the right side, the reference point for the assembly and quality control of the frames. Finally, the most obvious difference is the asymmetry of the inserts of the rear carriage, with the left now much wider.
Another important area where we have completely revised the technology is the rear wagon. The C64 dropouts are now an integral part of the horizontal stays. The one-piece construction allowed to lower weight, increase comfort and maintain the same lateral stiffness. This disc version is characterized by the same full carbon construction as well as a 12 mm rear axle and the directly co-molded flat-mount brake housings. The replaceable gear dropout is the same, internally mounted, used on other carbon frames (V2, Concept, C-rs, K.one). The lightweight vertical monocoque is designed around large tires and houses direct-mount brake couplings.
Rear tire space
While reducing weight has been the key to the project so far, the space for larger section tires has been another important factor considered in the C64 design. The frame is designed with a maximum footprint of 36.5 mm, which translated into simple words will allow you to use 28 mm tires with enough space to pedal peacefully in all conditions.
