Ritchey WCS Carbon Logic Headset

Zero Stack means the headset cups are pressed into the frame so that the bearings sit inside the head tube rather than outside. The ZS44 specification indicates a 44mm inner diameter head tube, which is a common standard for modern frames designed to accommodate tapered forks.

Yes, this headset is specifically engineered for tapered fork and frame combinations. It is designed to interface seamlessly with the wider base of a tapered steerer tube.

With a stack height of 18.3 mm, this headset sits very close to the head tube. This allows you to lower your stem height for a more aggressive, aerodynamic position or to fine-tune your cockpit geometry without needing to remove spacers.

The titanium coating on the angular contact bearings serves two purposes: it significantly increases the hardness of the bearing surfaces for smoother steering and provides superior resistance against corrosion, which is especially beneficial for gravel riding in wet or gritty conditions.

While it looks sleek, the carbon fiber bearing cap is primarily functional. It helps keep the overall weight of the headset down while maintaining the necessary structural integrity to protect the top bearing from the elements.
