WCS Zeta Wheels

Tom Ritchey created the Zeta wheels to be precise and predictable for carving endless ribbons of smooth tarmac tough, yet durable and reliable enough to endure cyclocross races and gravel rides that would chew lesser wheels to pieces.

With a CNC-machined braking surface for smooth control and stopping power, the alloy rims of the WCS Zeta are tubeless-ready with pre-installed Ritchey rim tape for easy set up and, importantly, simple access to the spoke heads for repairs and replacement when needed. The rear rim features Ritchey’s pioneering OCR™ technology - off-center spoke hole drilling that delivers more equalized spoke tension throughout the wheel, resulting in a stronger wheel. With a 20mm inner width, these rims welcome tires between 25 and 43mm wide – ideal for all your favorite riding disciplines.

At the heart of these rim brake wheels lies the legendary Phantom Flange system, paired with a precision Ratchet Driver system in the rear hub. The Phantom Flange hubs provide the sleek profile of straight-pull spokes while maintaining the strength and reliability of traditional J-bend spokes, striking a perfect balance between aesthetics, performance, and serviceability. Inside the rear hub, the innovative Ratchet Driver system offers a 360-degree, 36-point engagement, ensuring direct-drive efficiency and unparalleled power transfer.

Doubling down on the serviceability of these wheels, you can easily remove…without tools…the freehub body, axle, and Ratchet Driver system for basic periodic maintenance - and to lay flat when packing in a Ritchey Break-Away travel case.

The Ritchey WCS Zeta wheels are not just built; they are crafted to endure the toughest of rides, setting a new standard in wheel performance. And they’re the most versatile Ritchey wheelset on offer.

Every Ritchey wheelset is carefully hand-built by a qualified Ritchey wheel technician.
