Ritchey WCS Zeta Disc 700c Wheelset

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

Updated for 2024, the heart of the Zeta Disc wheelset features new smooth-rolling WCS forged disc hubs. Inside the rear hub sits the innovative Ratchet Driver system offering a 360-degree, 36-point engagement that ensures direct-drive efficiency and unparalleled power transfer.

The tubeless-ready extruded alloy rims of the WCS Zeta feature Ritchey’s pioneering OCR™ technology—off-center spoke hole drilling that allows equal spoke tension throughout the wheel, resulting in an easily dished strong wheel. These wheels ship with pre-installed Ritchey rim tape for easy setup and, importantly, simple access to the spoke heads for repairs and replacement when needed. With a 20mm inner width, these rims welcome tires between 25 and 45mm wide.

The updated WCS Zeta Disc wheels leverage Ritchey’s deep legacy of wheel research and design to deliver the perfect balance between performance, aesthetics, serviceability, and affordability—an ideal combination on which to build a lifetime of extraordinary ride experiences.
