What Our Gearhead(R) Experts Are Saying: "I've been rallying the Gradient i30s through everything from fast, flowy trails to harsh, technical descents-they're incredibly compliant without feeling vague. The 72-point hub engagement is snappy, and the hookless carbon rims have shrugged off hard hits with no issues. They give me full confidence every time I drop in."When our ride calls for charging steep chutes and hammering through rock-laced descents, we lean on the Gradient i30 Enduro 29in Carbon Boost Wheelset. Built by FSA and developed in collaboration with elite riders like the Atherton Racing Team, these wheels are bred for World Cup lines and rowdy backyard laps alike. FSA uses a special carbon layup with a 22-24mm variable rim height for improved compliance and trail feedback, while the 30mm internal width offers a stable platform for modern high-volume tires. The PRS X-900 hubs deliver 72 points of quick engagement, wrapped in a 28-spoke asymmetric layout for balance and strength. With tire-insert compatibility and extra-wide walls to fight off pinch flats, these wheels are ready for the roughest lines we can throw at them.
