Industry Nine Hydra2 Grade-S wheelset for aggressive enduro and DH builds
What Our Gearhead® Experts Are Saying:
"The Hydra2 hub's 0.41-degree engagement is the headline, but the hollow bead wall alloy rim is what makes this wheelset work for serious DH and enduro use by absorbing impacts that would crack a standard rim. J-bend steel spokes keep it serviceable anywhere."
Why We Like It
The Grade-S pairs Industry Nine's strongest alloy rims with traditional J-bend steel spokes, prioritizing durability and serviceability over weight savings. The hollow bead wall adds pinch flat resistance and structural compliance on big hits. At 31mm internal width, the rim profiles modern enduro tires correctly across the 2.3 to 2.8-inch range. Its Full Power Class 1 E-bike rating means it handles motor-assist load without reservation.
