Classic Zeta Wheels

Cassette Body


Tom Ritchey designed the critically acclaimed Zeta to be wide, light and laterally stiff for great road riding experiences, yet still tough enough to endure gravel rides and cyclocross races that would chew lesser wheels to pieces. Building upon the legendary wheel-building and -design heritage of Ritchey, the Classic Zeta wheels tastefully balance modern features with the legendary and elegant high-polish silver aesthetic of the Ritchey Classic line. Featuring a wider tire profile, the Zeta wheels provide a more comfortable ride while improving handling. And the Phantom Flange hubs offer the sleek profile and direct-drive efficiency of straight-pull spokes, but still uses stronger, more reliable J-bend spokes for maximum performance and reliability.

  • Each Ritchey wheelset is hand-built by a qualified Ritchey wheel technician
  • Rear hub easily serviceable without tools, including cassette body removal
  • Concealed J-bend hub design for increased strength
