The following cone rings are available:

- Material: steel and aluminum

- Width (of the cilindrical part of the cone ring): 0.5 mm, 2 mm, 4 mm, 6.5 mm

- Surface of aluminum cone rings: the conical area is always smooth and non-serrated. The back side is either smooth (non-serrated) for knurled / serrated gear housings or it has 18 milled grooves for gear housings, that come with milled grooves.

- Surface of steel cone rings: the conical area is always knurled / serrated. The back side is either knurled / serrated for knurled / serrated gear housings or it has 18 milled grooves for gear housings, that come with milled grooves, too.

Do not mix up serrated cone rings with milled gear housings or vice versa. This wouldn't work together!
