Introducing Industry Nine's new Hydra Grade 300v2 Wheelset, the toughest alloy rimmed wheel in the Hydra custom alloy line, designed for downhill bikes, bike park builds, and eMTBs. Its hollow bead wall design boosts alloy wheelset performance to carbon rim levels, featuring wider bead walls for enhanced impact resistance and eliminating pinch points found in traditional hook-shaped rims. The triple cavity rim structure further strengthens the wheel, reducing impact deformation severity.

Built on the Hydra 32h system hub and spoke chassis, the Grade 300v2 wheels feature the innovative .52° engagement freehub system. With direct-thread hubshells and one-piece machined alloy spokes, these wheels deliver unparalleled ride quality and customizable aesthetics, setting a new benchmark in wheel performance and design.
