Fulcrum Wind 55 DB C19 Disc Center Lock Wheelset

The Wind 55 DB C19 Disc Center Lock Wheelset by Fulcrum – Aerodynamic Performance
The Wind 55 DB C19 Disc Center Lock wheelset by Fulcrum is a 55 mm-deep rim made entirely of unidirectional carbon fibre with an external width of about 27 mm. The 19 mm-wide inner channel with 2-Way Fit™ offers optimised mounting for tubeless tyres and combines 25 and 28 mm tyre widths with a wide rim profile. No conversion is necessary, the wheel is immediately ready for use even without a tube. In addition, the Anti Rotation System™ creates a firm and solid unit between spokes and hub shell, resulting in a responsive and aerodynamic Wind 55 DB wheelset.

Tubeless technology was first used in the automotive sector, then in motorcycles and finally in bicycles. After entering the MTB world, the time has come for their use on the road: Fulcrum has developed the 2-Way Fit™ technology to guarantee the perfect compatibility of Fulcrum tubeless rims even with normal clincher tyres with tubes. 2-Way Fit™ wheels are particularly versatile and therefore perfectly suited to every situation. Thanks to a special marking in the valve area, the tubes are mounted with high precision and the tube remains firmly stabilized in the clincher tyre. The valve for tubeless tyres can also be used safely. This offers the undeniable advantage that air can never penetrate during assembly due to inaccurate positioning.
The advantages are undisputed: tests have shown an incomparably high increase in smoothness. The absence of a tube prevents friction with the tyre and the perfect adhesion of the tyre to the rim prevents energy loss. A tubeless tyre cannot lose air abruptly through a hole and suddenly become flat, which is a clear safety advantage. There is also no danger of snake bites, as there is no tube that can be punctured.
What about a flat tyre? Don’t worry! One of the advantages of the Fulcrum 2-Way Fit™ system is the possibility of removing the tubeless valve and inserting a normal tube to get you home.

AFS Axle System™
The Axial Fixing System is the solution developed by Fulcrum to mount the disc rotor to the hub. The connection provided by the stop surface of the mount is greater than that of the already known standards, allowing greater structural rigidity and therefore more precise and efficient braking.

Mo-Mag™
After the nipples have been inserted into the rim via the valve opening during lacing, they are guided by a magnet to the point of connection with the rim.
With this simple and ingenious system, you get a wheel with no holes on the upper rim, but with conventional nipples for lacing!

Anti Rotation System™
This system takes the concept of the lacing system to a new level of performance. Fulcrum’s technicians have redesigned the spokes and hub shells to create a strong and solid unit. In this way, the spokes a) never lose their initial tension, keeping the wheel perfectly reactive and trued, and b) remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.
