For bikes with integrated headsets (such as the Ritchey Road Logic and Swiss Cross), the WCS Integrated IS Headset stands out above all others. This alloy headset bearing features stainless steel angular contact sealed cartridge bearings with a titanium coating for corrosion resistance, and they are packed with Ritchey high-webbing grease.

This system takes into account a combination of frame and fork dimensions. Both the top and bottom parts of the headset are marked by two alphanumeric identifiers. The first identifier indicates the type of headset (External Cup, Zero Stack, Integrated) and head tube diameter. The second identifier - separated from the first by a backslash - indicates the diameter of the steerer tube. When referring to a complete headset, the specifications of both top and bottom parts must be combined.
