Shamal™ Ultra™

The historical name which for many years has been a synonym for an aerodynamic wheel is back on the top again thanks to the Shamal™ Ultra™, the synthesis of fifteen years of evolution of high-performance wheels for racing bikes.

The super-new Shamal™ Ultra™ wheels incorporate all the innovations of recent years, consolidated in a product without paragon in terms of performance, strength, life and reliability.

The light alloy rims come from selected extrusions and are CNC-machined to optimize the mechanical specifications; they are welded rims with a ground braking surface and the spaces between the spokes are lightened by toroidal grinding.

The rim is dynamically balanced; in other words the imbalance of the mass as a result of the non-equivalence of weight between joint and valve is compensated by the extension of the toroidal grinding.

The top bridge of the rim is not drilled in the traditional way to fit the nipples, so that the use of rim-tape is pointless and the system is lightened further as a result.

Both the spokes and nipples and in light alloy, to provide rigidity, lightness and aerodynamics at an absolute level.

The central body of the hubs is made of carbon and the flanges of aluminum, specially machined to lighten them; the axle is in light alloy while the 15-ball bearings are adjustable, and also available optionally in ceramic in the best Campagnolo® tradition.

The right-hand flange of the rear hub is oversized to maximize torsional rigidity and therefore drive torque transfer.

The cam lever of the release mechanism is actuated bilaterally and symmetrically.

The result of all this design and manufacturing refinement is a light but strong wheel, snappy and reactive, laterally and torsionally rigid, but sufficiently comfortable in longer races.
