Ritchey WCS Zeta wheelset Tubeless Ready-QR Shimano road bike Cyclocross

Tom Ritchey has improved the critically acclaimed Zeta wheels to make them wider, lighter, and laterally stiffer, yet strong enough to be ridden on dirt roads and in cyclocross races where other wheels would crumble to pieces.

The WCS Zeta wheels feature several modern features that allow them to adapt to a variety of riding situations. With a wider tire profile, the Zeta wheels provide more ride comfort and better handling. The Ritchey Phantom Flange hubs with a low-profile design combine the advantages of straight-pull spokes with the stability of J-bend spokes.
