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.
The do-everything aluminum race wheel is wider, lighter and stiffer than ever—and now available in a tubeless disc brake version.
The Zeta Disc wheels feature new forged two-piece WCS disc hubs, and the disc-specific, tubeless Zeta OCR™ rims are light, stiff and wide. Forged, machined and staggered hub flange increases spoke bracing angle and builds a stronger, lighter wheel.
Each Ritchey wheelset is hand-built by a qualified Ritchey wheel technician
Rear hub easily serviceable without tools, including cassette body removal
Features
-
Reliable Performance. 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.
-
Handcrafted Precision. 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.
-
Off-Road Design. 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 Centre Rim) design of the rims balances the spoke tension to further increase the stiffness of the wheels.
