The new BMC Roadmachine Ultegra was launched with the most modern technologies applied to the painting. With its pure and clean lines and its speed at each angle. It has maximum pedalling efficiency and a high level of absorption ideal for long days of pedalling.
BMC applied the tuned compliance concept system to this frame for maximum absorption of terrain irregularities and rider comfort. This system is the one that has been developed for legendary classics, like Paris-Roubaix, seeking to alleviate the beating that their professional cyclists must endure on their cobblestones.
BMC applied the tuned system pleasing concept – TCC – which makes flexibility and stiffness able to work together, in such a way that the maximum balance between the rigidity and vertical flexibility – the bending level of the picture of a bicycle – is achieved. Since this combination of factors can consume up to 15% of the energy of a cyclist. Thus, CBT focuses on minimising this impact by leveraging the know-how and experience gained from years of bike design, creating the perfect balance between comfort and performance to shape quick and error-forgiving solutions.
Since all bike frames and forks have bending; and also radios, rims, seatposts, saddles, handlebars and power. BMC introduced slim and low straps, asymmetrical rear dropouts, carbon fork dropouts and a redesigned seatpost so that the frame flexes vertically, maximizing what they call “angle compliance”. Thus, the annoying sensations during an outing, such as the shocks and vibrations of the stones, are not transferred directly to the cyclist’s body.
Another characteristic of this this is both the diagonals, steerer tubes, rear pods and fork bridges. These are combined with high modulus carbon fibres to increase the stiffness of the structure and improve the efficiency of the cyclist’s energy transfer to the bicycle with pedaling. In addition, the torsional stiffness is improved by making the handling more intuitive, lighter and more precise. The frame uses the dual transmission integration – DTI –, which allows the cables to be guided so that it can be easily varied between mechanical and electronic changes, with total freedom when choosing the group you ride on the bike.
This model is mounted with the complete transmission Shimano mechanical ultegra, of sound solvency for any type of use, along with hydraulic brake system Shimano ST-R785 and a wheelset dt Swiss, among other components.
