Our cable system has been further enhanced by routing the cables inside the frames’s tubes. Our INTEGRATED ADJUSTER PLATE (IAP) is a special device which allows for the fastening and adjusting of cables. IAP seamlessly integrates with the frame, thereby bestowing Cento1SR with a very clean look where no elements are exposed to air resistance. Easily interchangeable to be compatible with different electronic group sets, the INTEGRATED ADJUSTER PLATE allows one to route cables inside the tubes and to redirect them towards the bottom bracket. Combined with the special cable guide plate located under the bottom bracket, IAP keeps cables neatly spaced from the down tube’s inside surface. Noise and shifting efficiency loss can occur when a cable does not maintain its position.

The dropout evolves and implements its name. The 3D DROPOUT is born. It is not a mere rear derailleur mounting plate anymore. The dropout now extends over a third dimension and serves also as a cable stop. This newly acquired third dimension leads to an especially stiff dropout compared to conventional fastening plates. Thanks to its generous size, we were able to create two holes (a larger one for the mechanic group set cable and a smaller one for the electronic cable) to route cable housing or cables without compromising the dropout’s stiffness. In this manner, the dropout may be used both for mechanical and electronic group sets. For the mechanical group set, it allows one to use a shorter cable housing sleeve and to have the shifter cable follow its natural curve since the rear derailleur cable is located closer to the fastening point. This improves shifting efficiency and smoothness. The exit routing is not the only improvement. The cable stop has been positioned above the drive-side chainstay, thereby keeping the cable flawlessly suspended within the stay. The internal cable routing through the down tube is kept at a distance from the frame’s inner surface to assure that there is no friction during shifting. The wiring exit point of the electronic group set has also been optimized as it is setback and above the drive-side dropout. This feature facilitates and expedites rear wheel removal and installation.
