Kortel Design Low Friction Rings
Kortel Design Low Friction Rings
Low friction rings
Our rings are made from a shade of aluminium chosen for its anodisation properties, in addition to its mechanical properties. It allows for the thickest hard anodisation, guaranteeing the longevity and quality of the rings.
We therefore go up to 50 microns of hard anodisation.

Pulley Range: Use up to 180°, significant material thickness, maximum strength |
