The Fulcrum Carbon wheelset Speed 55 DB is a high-end competition model designed for use with disc brakes. Thanks to the 2-WAY FIT™ technology developed by Fulcrum, the wheelset can be combined with both tubeless and clincher tyres. In addition to aerodynamics, the key words are low weight and ease of movement - characteristics that are guaranteed thanks to the use of USB™ ceramic bearings. These are characterised by extreme performance, as they reduce the coefficient of friction and eliminate internal friction, so that more energy is available for forward movement.

  • ASTM category 2: for use on roads, maintained dirt roads and gravel roads (on Touring and Cross Country bikes) with jumps up to a height of 15 cm
  • Twill Carbon fibre surface
  • Plasma freehub
  • Adjustable cup & cone bearing system
  • Reflective details
  • Incl. DRP kit, an additional seal kit to protect the bearings from rain, mud or dust during Gravel or CX use


2-Way Fit
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, inner tubes are installed 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 an inner 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 inner 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 inner 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.

Fulcrum has always been respected for the extreme smoothness and reliability of its hubs. These characteristics are due to the fact that all projects are developed in the R&D department and an almost manic attention is paid to every detail. The hubs with USB (Ultra Smooth Bearings) ceramic bearings further increase wheel smoothness and reduce weight and maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings. Improving your performance, whether in a competition or a ride with your friends, is now easier.

2:1 Two-to-One
At the moment when the rider pedals at full power, the rotation of the cassette causes the spokes on the freehub side to give way, resulting in a loss of rim tension. 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 2:1 Two-to-One Spoke Ratio patent, that is, with twice the number of spokes in critical areas. In this way, two spokes take over the task of one, the yielding and twisting of the wheel remains low and the transmission of the athlete's energy becomes much more efficient. Thanks to this patent, the spoke tensions are more balanced and the fatigue strength of rim, hub and spokes is much higher.
