The Zeta Disc wheelset is designed to deliver precise and reliable performance on the road. Ideal for long, fast rides on smooth tarmac, yet robust enough to withstand the demands of cyclocross racing and gravel tracks.
The forged WCS hubs offer particularly smooth running characteristics. In the rear wheel, the innovative ratchet driver system with 360° coverage and 36 ratchet points ensures direct power transmission and high efficiency.
The aluminum rims feature Ritchey's proven OCR technology, in which the spoke holes are drilled off-center. This enables a more even spoke tension and ensures a stable, easy-to-center construction.
With an inner width of 20mm, the rims are designed for tire widths from 25 to 45mm and therefore cover a wide range of applications.
The revised WCS Zeta Disc wheelset combines decades of experience in wheel development with a well thought-out balance of performance, ease of maintenance, aesthetics and value for money - an ideal basis for many years of exceptional riding experiences.
