The new Ritchey WCS Zeta GX wheelset rolls wide gravel rims & new WCS sealed hubs

Hailing from San Carlos, California, Ritchey Design has been providing the cycling world with innovative and kick-ass products for decades. Tom Ritchey, one of the legendary pioneers of the mountain bike in the 70’s, is still involved with design as the president of Ritchey. Their new WCS Zeta GX wheelset builds on those 50 years of experience, now with a focus on adventure.

This new wheelset does look very promising… it’s handbuilt, available, and selling for a price that is pretty damn wallet-friendly!

Let’s just start with the fact that Ritchey says these new wheels are “directly inspired by the reliability and top performance of the original Zeta Wheels, but meant shine in gravel.”  

The new WCS Zeta GX wheelset is a 28-hole, hand-built, and tubless-ready wheelset that uses the new Ritchey WCS hubs which have sealed bearings and Centerlock brake rotor mounts.

From the rear.

The Ritchey WCS rear hub on this wheelset uses the precise dual-star Ratchet Driver with 36-point engagement which Ritchie says will “provide reliable engagement, no matter the terrain.” Plus the rear hub can be disassembled without any tools, making the hub easy to service, possibly resulting in a headache-free experience. Drivers that are available for the hub include Shimano Hyperglide, SRAM XDR, and Campy N3W. The hubs are available in BOOST 110/148 and 100/142mm spacing.

DT Swiss Competition tapered spokes.

The spokes used on this wheelset are the DT Swiss Competition spokes that taper from 2.0 to 1.8. This combo Ritchey claims “males for a very robust wheelset that is strong where you need it and shaves weight where available.”

The rims on the Zeta GX wheelset are 6066 aluminum and feature a 25mm inner rim width, and are tubless-ready, being taped from the factory. All you need is a valve and some sealant and you are ready to rip.

Why is it that every time there are images of a “gravel bike” or product it shows what looks to be someone riding XC on a drop bar bike? That’s not gravel around here!

LOL! We’re about 2 product generations away from “gravel bikes” having flat bars, clearance for 2.25″ tires, and 100mm of front suspension travel.

“25mm inner diameter” seems a bit small for a bike

Agreed. “Inner diameter” likely should have been “inner rim width”
