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, and an incredible value for their price, the Comp Zeta GX wheels are built to be strong, dependable, and ready to rip, carve, and cruise through all your gravel adventures. And they’re reliable enough to make sure you can do it all again tomorrow.

Ritchey believes in high quality aluminum road wheels for several obvious reasons. First, they offer incredible performance and durability that’s hard to beat at any price. Second, the price is right. Tom Ritchey redesigned the critically acclaimed Zeta rim structure to be wider, lighter and laterally stiffer. making them ideal for great all round road riding experiences, yet still tough enough to endure gravel road rides and cyclocross races that would chew lesser wheels to pieces. Combining decades of historic ride-proven research and testing with modern standards, the Comp Zeta GX Disc is available for gravel in this Tubeless Ready version, offering the legendary Ritchey ride quality at a more attainable price.

With a 25mm internal width for the Tubeless Ready rim channel, the Comp Zeta GX Disc rim can easily and effective carry tires from 30-50mm volume. The 6061 aluminum alloy has proven to be both resilient and when extruded and joined properly, delivers an inherently stiff rim structure. The wheels are both laced 2x/2x with 28 spokes off the high flanged Ritchey hubs. A 3mm rim offset is used in the rear wheel Ritchey's proven OCR system for reduction in wheel dish, which allows the structure to balance spoke tension from side to side for a stronger, stiffer wheel. DT Swiss provides their strong and resilient 2.0 steel j-bend spokes and brass nipples for a secure, serviceable, and durable overall disc hub build. The Ritchey Comp Disc thru-axle hubset is well equipped to match the rims and spokes, with forged bodies and sealed cartridge bearings. The rear carries an alloy freehub body and available in Shimano or SRAM XDR options, in both 650b and 700c rim sizes. The disc rotor interface is the 6-bolt system, and the hubs are compatible with 12/100mm front and 12/142mm rear OR 15x110 front and 12x148 Boost Spacing option, depending on which wheelset you purchase.
