Ritchey WCS Zeta 28" wheelset, QR, Shimano HG
Ritchey WCS Zeta 28" wheelset
Ritchey WCS Zeta are reliable, lightweight and stiff wheels, ideal for road cycling, gravel or cyclocross. Thanks to CNC machined braking surfaces, they provide smooth and effective braking when using rim brakes. The aluminum rims are tubeless ready and factory-fitted with tubeless tape for easy installation.
The rear rim uses OCR™ technology with offset hole drilling for more even spoke tension and increased strength. Phantom Flange hubs, with their light weight and distinctive look, are designed with ease of maintenance in mind. The precise Ratchet Driver system with 36-point engagement ensures instant power transfer. Each set is hand-braided by Ritchey experts.
