Performance plus versatility equals maximum satisfaction: the Racing 4 Wheelset by Fulcrum


The Racing 4 from Fulcrum is able to deliver that little bit extra, regardless of the ground conditions ahead of you. Its lightweight, medium-depth rim profile makes it an ongoing discovery with an enviable approach and eyes focused on performance. With a 35 mm profile, the Racing 4 displays a successful balance between aesthetics and performance. The medium-depth rim profile makes a difference on flat ground when riding without punishing on climbs, where it remains lively and agile while re-accelerating.

Technology:


RPV Dynamic Balance™
The concept is simple and ingenious: balance the mass of the rim joint with an equivalent mass positioned exactly on the other side of the rim. On the top-of-the-range models, this is achieved by special machining in the area opposite the rim joint. The result is a wheel that is perfectly balanced during rotation.

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.

First, delivery took only one day to Emmen, Netherland. This can be compared to science fiction nowdays regarding covid-19 situation. Great job Bike-Components! Since delivery I made 140km with wheels at wet/cold conditions. They rolling very smoothly, silently... free-wheel is almost silent. The sound of cutting through air comes at speeds above 34km/hour. They feel stiff and strong, and are very responsive to turns. Bearings seems to be sealed good after these wet 140km, didn't see any water penetrated inside hubs. It's only 140km so far, and can't say a much, but first impression is that this wheels performing very well. So, that's why 5 stars (togheter with delivery service).
