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

With the Wind 40 model, “all-round” is the keyword, but not at the expense of performance: this wheelset was developed for daily rides on all roads, for example for training or for a long-distance race with the home group.

The 40 mm profile made entirely of unidirectional carbon fibres shows 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 racing bike and the Wind 40: simply mount it and discover a new level of performance. To this end, Fulcrum’s R&D department has combined some of the most proven technologies: The rim, made of unidirectional carbon fibre, is of the MoMag™ type and therefore does not have any nipple holes, which improves 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 pads with unparalleled precision to improve performance in all conditions, up to 30% in the most difficult rain conditions.

To transmit full power during acceleration, an oversize flange has been installed on the cassette side, with aero spokes arranged according to the two-to-one™ scheme. Wind 40: Technology, performance, substance, but in the end it will completely change the character of your road bike.

RDB Rim Dynamic Balance
The concept is simple and ingenious: balance the mass of the rim joint with an equal-value mass positioned exactly opposite.

2:1 Two-To-One Spoke Ratio
At the moment the rider pedals at full power, the rotation of the sprocket set causes the spokes to yield at the freewheel, resulting in a loss of tension in the rim. This causes excessive bending of the whole and this inevitably means a loss of energy. Fulcrum has solved this classic problem in cycling with its patented 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 takes the concept of the lacing system to a new level of performance.
Fulcrum’s technicians have redesigned the spokes and the hub shells to create a solid and solid unit. In this way, the spokes
a) they never lose their initial tension, keeping the wheel perfectly responsive and centred, and
b) that they remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.
