700c, 27-Inch & 650c

With a CNC-machined braking surface for smooth control and stopping power, the alloy rims of the Zeta Classic are tubeless-ready and, importantly, simple access to the spoke heads for repairs and replacement when needed. The rear rim features Ritchey’s pioneering OCR™ technology - off-center spoke hole drilling that delivers more equalized spoke tension throughout the wheel, resulting in a stronger wheel. With a 20mm inner width, these rims welcome tires between 25 and 40mm wide – ideal for all your favorite riding disciplines where you want to shine. At the heart of these rim brake wheels lies the legendary Phantom Flange system, paired with a precision Ratchet Driver system in the rear hub. The Phantom Flange hubs provide the sleek profile of straight-pull spokes while maintaining the strength and reliability of traditional J-bend spokes, striking a perfect balance between aesthetics, performance, and serviceability. Inside the rear hub, the innovative Ratchet Driver system offers a 360-degree, 36-point engagement, ensuring direct-drive efficiency and unparalleled power transfer. Doubling down on the serviceability of these wheels, you can easily remove…without tools…the freehub body, axle, and Ratchet Driver system for basic periodic maintenance - and to lay flat when packing in a Ritchey Break-Away travel case.

Tom Ritchey believes in high quality aluminum road wheels—they offer incredible performance and durability that’s hard to beat at any price. He designed the Zeta to be wide, light and laterally stiff—perfect for a great road riding experience, yet still tough enough to endure gravel rides and cyclocross races that would chew lesser wheels to pieces. Updated for 2024 with a 4-pawl freewheel and DT Industry spokes, the tubeless-ready Comp Zeta Disc wheels combine decades of historic ride-proven research and testing with modern standards to deliver the legendary Ritchey ride quality at a more attainable price.

Some of Tom's favorite experiences have been while pedaling his tandem all over the world with his wife, Martha. When he designed the new Outback TandM Break-Away, he wanted a wheelset that could withstand the rigors of riding tandems along varying surfaces. The result is the new Comp Zeta TandM wheelset. The Comp Zeta TandM wheels build upon all the advantages of the original Comp Zeta Disc wheels but include some tandem-friendly features. The quick-release disc hubs measure 100mm wide for the front and 145 in the back and are laced with beefier spokes and brass nipples to 36-hole Zeta tubeless-ready rims. Designed specifically for the Ritchey Outback TandM Break-Away frameset, the unique Comp Zeta TandM wheelset is strong, reliable, and integrates beautifully with the frameset for many miles of happy tandeming. - Tubeless-ready 6061 Alloy rim - Rim depth: 23.4mm - Outer rim width: 24.4 mm - Inner rim width: 19.5mm - OCR 3mm offset rims for reduced dish and increased strength - Hubs: forged disc hubs and sealed bearings - Freehub: steel—Shimano 10/11-sp - Axles: quick release front and rear (100mm front / 145mm rear) - Disc mount: 6-bolt - DT Swiss Champion 2.0—DT Swiss brass nipples (36 front & rear) - Lacing: 3x - Weight: 2077g/set (959g—front / 1118g—rear)

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.
