OXIC –
wear resistant brake surface

OXiC is a process in which a ceramic coating is electrochemically applied to the rim surface, making it extremely hard and wear resistant. The OXiC process achieves a high end looking, matte black finish which also guarantees the highest level of brake performance while reducing wear on the rim to the absolute minimum.

The ceramic layer is achieved similarly to anodizing, by submerging the rim in an electrolyte solution while applying an electrical tension between the rim as one electrode and the container as the other. The decisive difference between anodizing and OXiC lies in the millions of plasma discharges that occur between the electrolyte and the rim, applying high temperature and pressure on the developing oxide layer. Due to that, the developing oxide layer melts, flows and solidifies again. During this process the amorphous (not aligned) structure of the oxide converts to a crystalline (aligned) one. This is why OXiC is so hard and wear resistant.

Advantages of the OXiC rim surface

  • Very good and consistent brake performance in all conditions.
  • Unlike conventional aluminum rims which wear out due to the abrasive effect of the brake pad and particles picked up from the road, the OXiC rim surface is so hard, that the rim will not be affected by wear over the normal lifespan of a wheel. The only part that wears out is the brake pad (DT Swiss supplies all OXiC wheels with specific brake pads).
  • Since the ceramic layer is applied through a conversion coating process, the OXiC coating is able to deform with the rim, maintaining its superior properties even under high mechanical loads (conventional ceramic coatings tend to crack when exposed to mechanical stress).
  • The OXiC coating process uses no volatile organic compounds or heavy metals, making it a very environmentally friendly technology.
  • Black rims that stay black: Since OXiC does not contain any inks or dyes it is totally UV stable and won‘t fade or discolour in the sun.

Comparison of different materials

Conventional rims use aluminum brake surfaces. The comparison of different materials impressively shows the superior hardness of the OXiC coating. And in this context hardness equals wear resistance.

 

OXiCs superior structure:

Because of the way OXiC is formed, it has far better adhesion to the aluminium than traditional coatings such as anodising. It also performs better on sharp corners and complicated geometry, making sure the rims are protected all around.
