Fulcrum Wind 55 DB Road Wheel Set 28" 12×100/12x142mm XDR 11/12-speed Disc CL Clincher TL Black

In describing a racing bike wheel like Wind 55 DB, you start with aerodynamics: it’s time to try out on your bike how a finished and optimised profile down to the finest detail is able to make the difference.The 55 mm full carbon unidirectional rim, a full 27 mm wide, is the result of an endless cycle of tests, wind tunnel analyses and laboratory finishing.

Then on the road, with the main objective of reducing the effect of side winds on the ride as much as possible.

And this is what you notice when you choose to race on Wind 55 DB: it cuts through the wind, guarantees stability and consequently very high average speeds without excess effort.

Completing this package id the 2-Way Fit™, 19-mm internal channel, designed to offer the best support for tubeless tires and designed to best match the 25 and 28 mm sizes with the wide rim profile. Thanks to the Mo-Mag™ technology, no conversion will be necessary, the wheel is ready for use even without an inner tube.

If “Aerodynamics” is the first word that comes to mind to describe your new set of wheels, perhaps you should think of Wind as the 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.
