ing frame that strikes the perfect balance between performance and comfort. You can spend hours in the saddle on the Cento10NDR thanks to its specially designed endurance geometry and the ACTIFLEX system. The ACTIFLEX system is Wilier's new approach to absorbing rear vibrations generated by bumps on the road surface.
The sophisticated design of the steerer tube combined with the special form of the headtube allows us to route up to three cables inside the frame. The three cables enter the steerer tube through the Alabarda or Stemma & Barra. The shifter and brake cables are routed from the levers at exactly the right angle into the steerer tube. If you're using electronic gears and disc brakes, the bike will not have any exposed cables, giving the Cento10NDR a beautifully clean look.
The road bike market is evolving. New users are coming to the world of high-performance bikes with a variety of goals other than purely racing. They want more relaxed geometry, the option to fit wider tires and disc brakes, and the ability to cycle long distances without discomfort. Essentially, they want the perfect blend of responsiveness, performance, light-weight, ride quality and comfort. With the Cento10NDR, we have brought together all these aspects that until now belonged to completely different visions and experiences of cycling. We have woven our traditional racing DNA into the endurance world with the development of the ACTIFLEX project in 2014. Frame geometry is key when it comes to endurance bikes. To offer Cento10NDR riders the maximum level of racing comfort, the proportions between the frame tubes needed to be reconsidered. The final result is a position that is slightly shorter and taller than in traditional racing geometries, thanks to a shorter reach and a taller stack. This reach and stack combination gives a more comfortable position without using any spacers between the stem and the frame. How often do we see cyclists with pure racing bikes and several centimetres of spacers under the stem? Now with the Cento10NDR, the overall look of the bike will be clean, balanced, and race-ready.
The Cento10NDR is a race-ready frame similar to the Cento10PRO, our high-end, light, and aerodynamic racing model. As with the Cento10PRO, the Cento10NDR was developed according to NACA Low-Speed rules' aeronautical algorithms that allow us to design the frame tubes with the highest possible aerodynamic efficiency. Alongside the NACA algorithms, Wilier uses another important concept in aerodynamics: the Kamm theory. Indeed, all profiles are designed with a Kamm tail, reducing weight and increasing stiffness without negatively affecting the aerodynamic efficiency of the tube itself.
Cento10NDR was the first road bike whose frame and fork could be mounted with either type of brakes: flat mount 160 mm rotor disc brakes with thru-axles or traditional direct mount rim brakes with quick release. This solution expands the available configurations of the Cento10NDR, meaning the frame is always ready for an upgrade. The fork and rear triangle have been designed to accommodate a wide range of tires: up to 28 mm with the rim brakes or up to 30 mm with disc brakes.
ACTIFLEX is the heart of the Cento10NDR frame, a new way to connect the seatpost and seatstays. Using a carefully designed aluminium link and a technopolymer dissipater, we have given the rear wheel a few millimeters of travel. The torsional stiffness of the aluminium link remains comparable to traditional monocoque carbon seatstays, despite the ACTIFLEX. This stiffness gives the frame racing performance, while at the same time allowing the rear wheel to move up and down over bumps caused by imperfections in the road surface. Connected to the aluminum link is a dissipater that stabilizes the kinematic movement of the rear triangle. This special technopolymer has amazing physical properties, high atmospheric resistance, and can function in temperatures from -40°F to 302°F. The dissipater is made in three different colors to distinguish the different levels of density, meaning that ACTIFLEX can be fine tuned according to the weight of the rider and/or the type of terrain they typically encounter on their bike.
