Aluminum rim construction has largely given way to carbon in the performance wheel market, but the material still makes sense for riders who prioritize durability and serviceability over marginal weight savings. The Ritchey WCS Zeta Disc wheelset builds on this premise with heat-treated aluminum rims paired to Ritchey's Phantom Flange hubs, creating a disc-brake-specific system designed for gravel racing and endurance road applications where reliability matters more than grams.

The rim profile measures 24mm deep with a 21mm internal width, placing these wheels firmly in the modern wide-rim category that accommodates tire sizes from 28mm road rubber up through 47mm gravel treads without compromising sidewall support. Tubeless compatibility comes standard, with tape and valves included for immediate tubeless setup. The shallow depth keeps weight manageable while reducing crosswind sensitivity—a practical consideration when you're 80 kilometers into a gravel race and the wind picks up.

Phantom Flange hubs use a proprietary bearing system with tool-free access for maintenance, which means you can inspect and service bearings without pressing anything apart or hunting for specialized equipment. The 24-hole front and rear drilling keeps spoke count reasonable for weight while providing enough support for loaded riding. Center Lock rotor mounting accommodates Shimano's interface standard, and the freehub body accepts both Shimano HG and SRAM XDR driver configurations depending on your drivetrain choice.... Read More
