Ritchey WCS Zeta GX Gravel Wheelset

WCS ZETA GX GRAVEL WHEELS

While the WCS Zeta GX wheels might be a new product for Ritchey, one could argue their development has been in process for nearly 
50 years. Tom, often together with his mentor Jobst Brandt and other friends, has been blazing trails and riding rough stuff since 
the early 1970s. Riding dirt is literally in Tom’s blood.

Directly inspired by the reliability and top performance of the original Ritchey Zeta wheels, the new WCS Zeta GX wheelset is 
designed to shine in the gravel. These hand-built wheels are tubeless-ready and feature the new WCS hub with sealed bearings, and 
center-lock rotor mounts – with the rear hub housing a precise Ratchet Driver system with 360-degree, 36-point engagement. The 
rims offer a wide 25mm inner diameter, so they’ll nicely fit wider tires for gravel, and they’re laced with 28 sturdy spokes.

Tom Ritchey doesn’t carry a mobile phone when he rides. Nor does he bother with the hassle of following GPS coordinates on a 
cycling computer. A firm believer in self-reliance, one of Tom’s guiding design principals is that every Ritchey product needs to be 
reliable enough to get you home. Designed for durability and to perform in rough and rugged conditions in remote locations or close 
to home, the WCS Zeta GX wheels are built to be strong, dependable, and ready to rip, carve, and cruise through all of your gravel 
adventures – and reliable enough to make sure you can do it all again tomorrow
