Tom Ritchey believes in high-quality aluminum road wheels because they offer incredible performance and durability, 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 tough enough to handle the rocky road courses and cyclocross races that would rip less capable wheels to shreds. Combining decades of historic research and testing with modern standards, Zeta Disc is now available in a Classic tubeless-ready version that will add a timeless aesthetic to any build. Each Zeta wheelset is handcrafted by a qualified technician. The OCR® (Off Center Rim) design reduces the wheel's pitch to balance spoke tension for a stronger, stiffer wheel.
