WCS Apex 38 Tubeless Wheels

Cassette Body


The WCS Apex 38 is our most versatile wheelset - fast in the wind yet light enough for big mountain days. The tubeless design is perfect for low tire pressure cyclocross racing or everyday road riding. 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. The thermal-grade composites and resin system is optimized for rim brakes. Not only do these wheels perform spectacularly, they look amazing.

  • 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
