Industry Nine Hydra 2 DH S Wheelset
The Industry Nine Hydra 2 DH S is the most robust alloy wheelset in the I9 catalogue. It is specifically engineered to survive the "most abusive trails and E-bike use" by pairing the high-engagement Hydra 2 hub with the Grade 300 alloy rim. This wheelset features the "S-Series" configuration, which utilizes standard J-bend steel spokes for a more compliant, dampened ride quality and easier repairs at the trackside.
The core of the DH S is the Grade 300 v2 rim, which features Hollow Bead Wall technology. This triple-cavity design increases the bead wall width by 78%, which significantly reduces the likelihood of pinch-flats (snake bites) when running lower pressures on rocky terrain. Testing shows a 79% improvement in impact resistance over the previous generation, making it the benchmark for gravity-focused alloy wheels.

Our Wheelbuilders' opinion:
The Industry Nine Hydra 2 DH S is the heavy-duty "Privateer" wheelset in the I9 lineup. While the "System" wheels use proprietary aluminium spokes, the S-Series (Steel) DH S is designed for riders who prioritize the extreme durability and easy serviceability of traditional J-bend steel spokes for downhill, bike park, and full-power E-MTB use at a more affordable price.
Hydra 2 Drive System: Delivers near-instant 0.41-degrees engagement (870 P.O.E.) with a 60% reduction in coasting drag.
J-Bend Steel Spokes: Traditional 32-hole lacing for a robust, easy-to-service build that handles heavy G-outs better than aluminium.
E-Bike Approved: Rated for Full Power Class 1 E-bikes, with reinforced hub shells and a 65% thicker axle to handle massive motor torque.
Hollow Bead Wall: A wider, hollow rim edge that acts as a "buffer" between the rim and the tyre during bottom-outs.
Massive Payload: A suggested rider weight limit of 150kg—one of the highest in the industry for a performance wheelset.
