If you aim to rail through quick switchbacks, huck into blind landings, or tackle Sedona’s most demanding trails, you've got to have wheels that can take the abuse.

Industry Nine calls their Enduro 315 Hydra Carbon wheels category-defying. We call them perfect. Blending the strength of carbon rims with the reliability of one-piece aluminum spokes, I9 EN315’s are a top choice for riders looking for light-weight and rowdy-ready mountain bike wheels.

Built around the Hydra 32h chassis, the EN315 has a versatile and robust foundation. Featuring a groundbreaking 690 P.O.E., I9’s Hydra freehub gives you near-instant engagement at just .52 degrees. Its thicker bead wall also gives you added protection against pinch-flats and impact damage when the trail gets rough.

To craft their new carbon rims, I9 has partnered with Canadian carbon manufacturer, We Are One Composites. Each rim is hand-laid in Kamloops, BC, with I9 exclusive molds and specifications. Back in Asheville, NC, the rims are matched with I9’s proven straight-pull aluminum spoke and direct-thread hub system, resulting in a top-in-class, aggressive wheelset that’s entirely engineered, manufactured, and assembled in North America.

I9 takes serious pride in their craft. For as long as you own these wheels, they’ve got you covered with lifetime warranty coverage against defects.
