Fulcrum Wind 40C C17 Wheelset Road 28" HG 8-11-speed Clincher black

All-round" is the keyword for the Wind 40 model, but not at the expense of performance: This wheelset is designed for daily rides on all roads, for example, for training or for an endurance race.

Here, the 40mm profile made entirely of unidirectional carbon fibres plays up its strengths: Aerodynamics and stability on long flatland stages, lightness and agility when changing pace uphill, safety and agility on technically demanding descents.

You will immediately notice the balanced and harmonious interaction between your road bike and the Wind 40: simply mount and discover a new level of performance. To this end, Fulcrum's R&D department has combined several of the most proven technologies: Made of unidirectional carbon fibre , the rim is Mo-Mag -type and therefore does not have nipple holes, which is good for stiffness and reliability.

The brake flanks machined with the AC3 laser process provide braking performance like never before: Laser machining eliminates resin residues on the contact surface with the brake shoes with unprecedented precision to improve behavior in all conditions, up to 30% in wet/rainy conditions.

To transmit the full power under acceleration, an oversize flange was installed on the cassette side, with aero spokes arranged according to the two-to-one scheme. Wind 40: Technology, performance, substance combine to remake your riding experience.

RDB Rim Dynamic Balance
The concept is simple yet ingenious: balance the mass of the rim joint with a mass of the same value, positioned exactly opposite.

2:1 Two-To-One Spoke Ratio
At the moment when the rider pedals with full force, the rotation of the sprocket pack causes the spokes on the freewheel to give way and the rim to lose tension. This causes an excessive bending of the whole and this inevitably means a loss of energy. Fulcrum has solved this classic problem in cycling with its patent 2:1 Two-to-One Spoke Ratio, that is, by doubling the number of spokes in the critical areas.

Anti-rotation system
This new system brings the concept of the spoking system to a new level of performance.
Fulcrum engineers have redesigned the spokes and hub shells to create a strong and solid unit. Here’s how this applies to the spokes:
a) that they never lose their initial tension and the wheel remains perfectly responsive and centered and
b) they remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.
