Meet every challenge the mountain throws at you. The Hydra2 Enduro S V2 6-Bolt Wheelset hails from Industry Nine's legendary Enduro lineup, built on a philosophy where do-it-all versatility isn't just a feature, it's the foundation.
An Icon, Reimagined
Industry Nine's best-selling rim of all time just raised the bar. The redesigned Enduro S prioritizes strength and longevity with its advanced Hollow Bead Wall Technology, purpose-built to minimize pinch flats while maximizing impact protection. This battle-tested innovation empowers you to charge harder, drop tire pressures lower, and attack the most unforgiving terrain without hesitation.
Rowdy Descents, Marathon Endurance
Engineered around a robust 30.5mm inner rim width and reinforced with a substantial 32-hole spoke count, the Enduro S V2 brings authentic expert-level capability to riders tackling the most challenging lines. The generous width maximizes modern enduro tire performance for unshakeable grip through corners and absolute composure on punishing, steep descents. But this wheelset thrives just as easily on long-haul adventures, crushing full-day rides without a hiccup. Ferocious when conditions get rowdy and steadfast when you're logging serious miles, the Hydra2 Enduro S V2 doesn't ask you to choose.
Game-Changing Hydra2 Hub Engineering
Driven by Industry Nine's innovative Hydra2 hubs, the Enduro S V2 wheelset offers instantaneous engagement and the unbreakable dependability that made i9 famous. With explosive response when you lay down the power and bulletproof consistency on deep wilderness missions, these hubs are designed to excel.
Elite Performance for Epic Mountain Adventures
Equipped to deliver top-tier performance with state-of-the-art hub technology, the Hydra2 Enduro S V2 6-Bolt Wheelset is built for conquering serious mountain objectives. Bike park sessions to remote wilderness explorations, jagged rock sections to wide-open berms, this wheelset rises to meet any terrain you choose.
