    Tom Ritchey believes in high-quality aluminum road wheels—they offer incredible performance and durability that’s hard to beat at any price. He redesigned the critically acclaimed Zeta to be wider, lighter and laterally stiffer—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. Combining decades of historic ride-proven research and testing with modern standards, the Zeta Disc is now available in a tubeless-ready Comp-level version, offering the legendary Ritchey ride quality at a more attainable price. Each Zeta wheelset is hand-built by a qualified wheel technician. OCR® rims design (Off Center Rim) reduces wheel dish to balance spoke tension for a stronger, stiffer wheel.
