Rotors

The core
of the brake

SICOM C-C/SiC rotors are made matching patented innovative components with special processes.
Where competitors use short fibers, with the SICOM brake systems it has introduced a 3D matrix for the internal core plus an outer layer of extreme hard carbon fiber.
These components take advantage of a patented production process, that allows SICOM brake systems to be unique in lightness and resistance.
Thanks to new silicon-infiltration-technology the increased superficial hardness allows to use pads with higher friction coefficient and guarantees a longer rotor life.

The new generation of production process and technology gives 25% lighter rotors if compared with other carbon ceramic competitors

AxialFlow TM

Each SICOM C-C/SiC rotor presents a patented ventilation geometry, obtained with 5° bent axle of the cooling channels, designed and developed in order to maximize flow and cooling efficiency. With this improved cooling fluid dynamics, there's no more the necessity of the additional axial cooling holes.
This works in the direction of maximizing the effective rotor-pad contact area.

Obviously the rotors can be designed to be adopted on standard non SICOM calipers, where the two braking surfaces are on the same planes.

Perfect cooling Efficency

The bell is made with 7075 T6 aluminium alloy machined from forged billet and matt black anodized for corrosion protection and it has a lot of special features:

  • its special design is studied to allow a triple cooling flow: one to the inner braking surface, one to the outer braking surface and one inside the rotor
  • the thickness of the flange is so calculated that no additional spacers are required to fit into OEM wheels.
  • the flange has key design item: the flange is in direct contact with the rotor and it helps dissipating heat because the outer design of the bell has radiant surface, like the air-cooled engines.
