If you need a great replacement headset for your Zero style drop-in headtube, Ritchey WCS headsets have always been built to exacting tolerances and featured high quality sealed cartridge bearings. This WCS Logic Zero Drop in Headset was built for 1⅛ fork designs and frames that require drop-in style bearings with 41.8mm upper and 41.8mm oustside diameters.

Ritchey uses corrosion-resistant Ti-coated bearings for the WCS headsets so you can trust the product to be protected and not to interact negatively with your frame material. The stiff and durable alloy 9.9mm stack height collar and top cap keep your adjustment fine tuned and alignment perfect.
