The rim

New aluminum rim with a wider section: ETRTO 17C, external width 22,5 mm.

The milling

The combination of triple milling + "Square Milling" makes it possible to reduce the peripheral weight of the rim and to increase the reactivity of the wheel.


Differentiated rim height: 27 mm at the front to have a good handling; 30 mm at the rear to transfer all the power to the wheel.

Hubs

Smoothness is ensured by the famous CULT™ 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 carbon hubs 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 pedalling tempo and more efficient power transmission to the wheel.

Spokes and nipples

Aluminum spokes: a precise choice to ensure optimal rigidity and a special attention to aerodynamics.


Aluminum nipples: thanks the light weight they reduce the peripheral mass, enemy of reactivity.
