While the WCS Zeta GX Boost Wheels may be a new product for Ritchey, one could argue that their development has been in progress for nearly 50 years. Tom Ritchey, 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 almost literally in Tom's blood.
Directly inspired by the reliability and top performance of the original Ritchey Zeta wheels, the new WCS Zeta GX Boost wheelset is designed to shine on gravel. These hand-built wheels are tubeless-ready and feature the new WCS hub with sealed bearings, center-lock rotor mounts – with the rear hub housing a precise Ratchet Driver system with 360-degree, 36-point engagement, and of course, boost spacing. 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 principles 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 Boost 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.
