Ritchey Classic Zeta Disc Wheelset

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 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 Classic finish version that is sure to add a timeless aesthetic to any build.
