Pitched as Campagnolo’s plan for big success on the wheel market, the groupset manufacturer has introduced the new Zonda 2-Way Fit – a dual option tubeless/standard clincher wheel being introduced for 2010.
Thanks to the 2-Way Fit profile, it is possible to take advantage of both tubeless and conventional tire technologies: performance, comfort, and road holding with the former, practicality and economy for the latter.
According to Campagnolo, what’s most surprising for this new wheel is the ‘truly extraordinary work accomplished’ in regard to weight, coming in at 1580g.
This is the result of attention to detail: the thickness of the rim extrusion has been reduced, thereby eliminating all the excess material, and the rim has been lightened between one spoke and another.
The steel spokes feature aero geometry and differentiated thickness, and are different sizes depending on their function: more slender in the less critical positions, sturdier in the most critical.
The company has utilised 2.2/2/1.5/2 spokes for the front and the left side of the rear wheel and 2/1.8/2 for the rear wheel cassette side, where the spokes have to bear the maximum load.
In addition to the weight, Zonda 2-Way Fit features a new antirolling system for the spokes, which keeps the spokes ‘constantly in the ideal position to ensure perfect aerodynamic penetration.’ The hubs also have a new design, further increasing the smoothness of the ride.
