Ritchey WCS Zeta GX Gravel Wheelset – 700C | Tubeless | Centerlock – 12x100mm | 12x142mm – Campagnolo N3W

Although the GX wheels present themselves as the youngest model of the Zeta series, they represent in some ways the result of 50 years of development. Already in the early 1970s Tom Ritchey and his mentor Jobst Brandt made their way over rough Trails. Off-road riding is literally in Tom’s blood.

 

So with its focus on Gravel Riding, the WCS Zeta GX wheelset represents a return to basics, enhanced and optimized by decades of innovation and inspired by the reliability and top performance of the original Zeta model. Durability and the certainty of not only mastering the harsh conditions of remote areas, but also bringing the rider back home without any problems, are inherent in all Ritchey components and were a key element in the design of the Zeta GX in particular.

To excel when riding on gravel, the hand-built wheels are not only Tubeless Ready, but also feature optimized WCS hubs with sealed bearings. The rear hub also features a precise Ratchet Driver system with 36 teeth and a 10° engagement angle.

With 25 mm, the distance between the rim flanges is wide enough to provide sufficient space for off-road tires of larger dimensions. To stand up to any Gravel adventure, 28 rigid DT Swiss Competition spokes do their job at the front and rear, while the OCR (Off Center Rim) design of the rims balances the spoke tension to further increase the stiffness of the wheels.
