Road bike rims - Racing Zero (clincher/two way fit)

The rim

This special triple milling makes it possible to reduce the peripheral weight of these road bike rims and to increase the reactivity of the wheels.
Differentiated rim height: 26mm at the front to have a good handling; 30mm at the rear to transfer all the power to the wheel.


The front hub has been redesigned, the new model is smaller and so lighter.
Smoothness is ensured by the famous USB™ ceramic bearings. The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, increasing the smoothness and durability.
The front carbon hub and oversize aluminum rear flange provide an innovative mix that provides excellent torsional rigidity and consequently a greater reactivity.
Greater reactivity to each change in pedaling time and more efficient power transmission to the wheel.

Spokes and nipples - Racing Zero (clincher/two way fit)

Spokes and nipples

Aluminum spokes: a precise choice to ensure optimal rigidity and a special attention to aerodynamics.
Aluminum nipples: thanks to the light weight they reduce the peripheral mass, enemy of reactivity.

2 Way Fit version

The advantages are indisputable: our tests have highlighted an unique increase in smoothness.
There is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the road bike rims prevent the dispersion of energy. There is also no risk of snake bites as there is no tube to rupture. What if a tubeless tyre gets punctured?
With Fulcrum 2-Way Fit™ you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.
