Fulcrum Wind 55 DB Wheelset Road 28" HG 8-11-speed Disc CL Clincher TL Black

Performance through aerodynamics

When describing a racing wheel such as the Wind 55 DB, one inevitably has to start with aerodynamics: It is time to try out on your own bike how a precisely machined and optimized profile can make all the difference.

Made entirely of unidirectional carbon fibres, the 55 mm rim, with a width of around 27 mm, has been developed through endless test cycles, wind tunnel tests and laboratory studies. It was then tested on the road to minimise the influence of side winds on pedalling dynamics.

This is noticeable when using the Wind 55 DB in racing: it is insensitive to wind, guarantees high stability and high average times without fatigue.

The 19 mm inner channel 2-Way Fit completes the package, it offers the best mounting for tubeless tyres and combines the sizes 25 and 28 mm with the wide rim profile in an optimal way. Thanks to MoMag technology, no conversion is necessary and the wheel is ready for immediate use even without the inner tube.

If the first thing you think of when describing your new wheel set is “aerodynamics”, you may want to consider wind as your first choice.

2-Way fit
Tubeless technology was first applied to the automotive sector, then to motorbikes and finally to cycle racing. After entering the MTB world, the moment has now come for its use on the road: And that’s what they offer you now! They have developed the 2-Way Fit technology to guarantee the perfect compatibility of tubeless rims also with normal clincher tyres and tubes. 2-Way Fit wheels are particularly versatile and therefore perfectly suited to any situation.

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.

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.
