Specialized Allez Sprint Frameset - 2023 Model

The Allez Sprint frameset by Specialized - forward onto victory with this aluminium superbike

The Specialized Allez Sprint is a super-fast aluminium frame, complemented by carbon fork and seatpost, with the geometry and looks of the carbon Tarmac SL7 racer. Based on its aerodynamics, this frame brings all your power to the road. The hydroformed tube construction and D'Aluisio Smartweld welding technology, the highly complex head tube and the internal cable routing ensure optimum power transmission and riding dynamics at their best. The one-piece bottom bracket and down tube ensure that you manoeuvre safely and stably at all speeds, be it in the sprint to the finish line, in the decisive attack or when accelerating out of a corner. Thanks to its carbon fork, carbon seatpost and lowered seat stays, riding comfort is not neglected either. No wonder US cycling star Justin Williams relies on the Allez Sprint aluminium superbike when he whizzes around the corners and speeds across the asphalt in downtown LA.

Technology:

D'Aluisio Smartweld Technology (DSW)
D'Aluisio Smartweld welding technology, named after its inventor Chris D'Aluisio, is based on so-called hydroforming. Hydroforming is a process that uses hydraulic pressure to shape aluminium. A flange with seam preparation is then formed, which is then welded. This improves accessibility during welding, produces cleaner welds due to more even heat distribution and distributes the jump in stiffness over a larger area. This not only ensures smoother stiffness transitions and lower load peaks, but also contributes to material and weight savings because thinner wall thicknesses can be used. This technology makes it possible to get the best out of aluminium, and to produce frames that are nearly comparable to carbon models in terms of precision and strength, but are naturally much more affordable.

Aerodynamic Expertise from Specialized
" Aero is everything" is not an empty slogan at Specialized. Their engineers rely on decades of experience in aero design, and use a variety of state-of-the-art methods in the developing top aero racing machines. Central to this, of course, is the wind tunnel (" Win Tunnel" ) at the company's headquarters in California, which is available for round-the-clock testing. It is specially designed to meet the requirements of cyclists and typical situations in road cycling, such as team time trials or riding in a group. The development process always begins with the FreeFoil Shape Library, a collection of countless tube shapes and structures which helps engineers figure out the most interesting configurations for wind tunnel testing. But one does not always have to analyse actual objects. There is also Computational Fluid Dynamics (CFD), which uses computer simulations to experiment with aerodynamic properties. Specialized also makes use of the Data Acquisition System (DAQ), which collects data such as a rider's power, speed, riding position and wind angle of incidence during practical tests on the road or in the velodrome. In turn, conclusions can be drawn from all this information for use in bike fittings and fine tuning.
