700c, 27-Inch & 650c

Tom Ritchey redesigned the critically acclaimed Zeta to be wider, lighter, and laterally stiffer. Yet, these wheels remain tough enough to endure gravel road rides and cyclocross races that would chew lesser wheels to pieces. Building upon the legendary wheel-building and design heritage of Ritchey, the WCS Zeta wheels offer modern features that allow them to perform gracefully in a variety of ride settings. Featuring a wider tire profile, the Zeta wheels provide a more comfortable ride while improving handling. The Phantom Flange hubs offer the sleek profile and direct-drive efficiency of straight-pull spokes, but still use stronger, more reliable J-bend spokes for maximum performance and reliability. - Each Zeta wheelset is hand-built by a qualified Ritchey wheel technician - Rear hub completely serviceable without tools, including cassette body removal - Concealed J-bend hub design for increased strength and ease of service - Rims: tubeless 6066 alloy rim, CNC machined braking surface, OCR rear rim - Rim depth: 23.8mm - Outer rim width: 24.4 mm - Inner rim width: 20.0mm - Hubs: proprietary super-light Phantom Flange hubs with hidden J-bend spokes - Freehub material: alloy - Disc brake compatibility: No - Axle compatibility: standard quick release only (Ritchey forged quick releases included) - Spokes: DT Aero Comp - Front: 20 spokes / radial - Rear: 24 spokes—radial non-drive side / 2X drive side - Nipples: 2.0 brass 12mm - Weight: 1468g/set (648g—front / 820g—rear) - Do not use sealants containing ammonia
