Tom Ritchey believes in high quality aluminum road wheels because they offer incredible performance and durability that’s hard to beat at any price. He designed the critically acclaimed Zeta to be wide, light and laterally stiff—perfect for a great road riding experience, yet still tough enough to endure gravel road rides and cyclocross races that would chew lesser wheels to pieces. Updated for 2024 with a 4-pawl freewheel and DT Competition spokes, the tubeless-ready Classic Zeta Disc wheels combine decades of historic ride-proven research, testing with modern standards, and a sophisticated aesthetic to deliver the legendary Ritchey ride quality at an attainable price.
Each Zeta wheel set is hand built by a qualified Ritchey wheel technician
Rear OCR® (Off Center Rim) design reduces wheel dish to balance spoke tension for a stronger, stiffer wheel
