Tubeless, disc and thru-axle version of Ritchey's do-everything aluminum race wheel

Tom Ritchey believes in high quality aluminum road wheels—they offer incredible performance and durability that’s hard to beat at any price. The Zeta is wider, lighter and laterally stiffer, yet still tough enough to endure gravel roads and cyclocross races that would chew lesser wheels to pieces. Disc brake version features new two-piece forged hubs and disc-only OCR rim extrusion.

  • Two-piece forged and machined disc hubs with 12mm front thru-axle and 142x12mm rear
  • Disc-specific, tubeless Zeta II OCR™ rims are light, stiff and wide
  • Forged, machined and staggered hub flange increases spoke bracing angle and builds a stronger, lighter wheel
  • Centerlock compatible
  • 1,560 grams (735g front, 825g rear)



  • Rims: WCS Zeta II Tubeless OCR – disc-specific
  • Proprietary Ritchey extrusion balances ride quality and aerodynamics
  • Rear OCR® (Off Center Rim) design reduces wheel dish to balance spoke tension for a stronger, stiffer wheel
