Nobody explains it better than Deda. Here’s their ditty:
THE FRAME ATLETA HAS BEEN STUDIED FOR THE ASPIRING CHAMPION.
Muscled with an aero shape profile it is well suitable for flat stages and for the combative sprints, gritty and unfailing it is superior in the longest uphill and descents.
ATLETA is the total combination of the best Japanese carbon fiber produced by Toray with the crucial carbon fiber lay-up disposition in order to get light and reliable carbon tubes. These technologies allow to produce a superior frame kit furthermore it is able to provide the best driving sensations, rigidity and harmony with the rider, mostly in the tough stages when the pedal action becomes hard and tied. The areas of maximum stress: the bottom bracket, head tube and seat tube are all strengthened in order to maintain a high degree of stiffness whilst retaining the parallel alignment of the wheel axes during the pedal stroke.
The Dedacciai frame building process is called Nano Technology. The Dedacciai manufacturing technology is based upon a special epoxy resin which is able to fill the microscopic spaces between carbon fibers and the molecules in order to bond the fibers to each other with a longer life for the frame. That process allows production of a fiber and resin Prepreg composite which has better qualities compared to ordinary Prepreg. Less carbon fibers, reducing total frame weight, and high torsion ratio are the main features of Nano Technology.
The Atleta frame kit has been engineered and studied with fluid-dynamic test in order to obtain the best air penetration aerodynamic ratio. The shapes of head tube, down tube and seat tube allow 15% save of air resistance respect to the common round tube shape. Furthermore the seat post clamp has been putted inside the top tube in order to obtain the best aerodynamic performance. We suggest to use a torque wrench to fix the seat clamp at 10 Nm.
ATLETA is equipped with the PF 30 (press fit 30) with bottom bracket length of 68 mm. Dedacciai offers BB30 and BSA adaptors as spare parts. The PF30 (press Fit 30) standard has the classical bearings insertion BB30 (42 mm) in the Bottom bracket within pressure plastic caps. The central bottom bracket has an ID of 46 mm. The PF 30 adopts a bottom bracket with a bigger inner diameter compared to those available in the market.
The frame kit ATLETA is also equipped with a monocoque carbon fork with tapered steering tube of 1”1/8 top and 1”1/2 bottom in order to grant an higher reliability standard on every kind of surface.
Atleta is fully compatible with mechanical and electronic shifting systems running the cables inside the down tube and in the chain stays, via an internal carbon bottom bracket passage. The refined attention to details could be seen in the routing of the rear derailleur wire through the alloy rear dropout. The frame is also compatible with cable-operated shifting systems. That double compatibility is obtained by replacing small parts through the “cable stopper” system described above.
