The new Industry Nine Hydra Grade 300v2 rear wheel is engineered to be the toughest and most resilient alloy rimmed wheel in the Hydra custom alloy lineup. Ideal for downhill bikes, bike park builds, and eMTBs, its innovative hollow bead wall design boosts performance to levels typically seen in carbon rims. This design features wider bead walls for enhanced impact resistance and eliminates the pinch points common in conventional hook-shaped rims. The triple cavity rim structure further strengthens the wheel, significantly reducing the severity of impact deformations.
Built on the Hydra 32h system hub and spoke chassis, the Grade 300v2 wheels feature the groundbreaking .52° engagement freehub system. With direct-thread hubshells and one-piece machined alloy spokes, these wheels offer unmatched ride quality and customizable aesthetics, setting a new standard in the market.
