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. - Each Zeta wheelset 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 - Tubeless-ready 6061 Alloy rim - Rim depth: 23.8mm - Outer rim width: 24.4 mm / Inner rim: 20mm - OCR 3mm offset rear rim for reduced dish and increased strength - Hubs: Forged disc hubs and sealed bearings (Front: 2 bearing/rear: 4 bearing) - Freehub: Alloy—Shimano 11-sp - Axles: 100x12mm Front / 142x12mm Rear - Disc mount: 6-bolt - DT Swiss 2.0 and DT Brass Nipples (24 front/24 rear) - Lacing: Radial front/ 2x rear - Finish: High-Polish Silver - Weight: 1715g/set (782g—front / 933g—rear) - Do not use sealants containing ammonia
