2:1 TWO-TO-ONE™ SPOKE RATIO
What is Two-to-One™?
A system that is as simple as it is effective, the result of the ingenuity of the Fulcrum® engineers and attentive observation of the results of the tests performed on the wheels on a daily basis.
These tests made it possible to understand that the forces that act on the sides of the wheel, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to making room for the sprocket set, has to compensate for the traction of the force on the chain side.
So how can we keep the wheel perfectly in balance even when it is stressed by braking and acceleration? By doubling the number of spokes and positioning them in such a way that, for each stress on one side of the wheel, there is an equal and opposite force on the other side. This may seem like a simple solution, but especially on harsh and demanding terrains like those of off-road riding, the 2:1 Two-to-One™ system is crucial for ensuring consistent control of your bike even in the most critical situations.
Advantages: The advantages are truly striking.
In braking, the front wheel maintains the desired trajectory and does not skid, while the rear wheel, precisely due to this spoking system, reaches a high level of torsional stiffness that enables the optimal transfer of power to the wheel. The 2:1 Two-to-OneTM system also makes it possible to reduce the unit load sustained by each spoke, and this minimises mechanical stress, prolonging the life of the wheel.
