For those who always want the next best thing.

We might say it is the fastest ever aluminum Racing Zero – the perfect definition! A breathtakingly smooth run (thanks to CULT™ technology).

This rim is born to take on the bends, without giving a centimeter. “Competizione”, for the truly competitive.

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.


  • 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 pedaling 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 to being lightweight they reduce the peripheral mass, the enemy of reactivity.
