Built for hard-charging all mountain trail riding, the Industry Nine 1/1 Enduro S Carbon Wheels pair I9's fast-engaging 1/1 hubs with a robust 30mm wide carbon rim for the optimal balance of performance and price. The 1/1 Mountain Classic hubs feature 90 points of engagement, so you can maneuver confidently and accelerate quickly through technical sections of trail. Unlike some carbon wheels, the 1/1 Enduro S Carbon wheels use traditional and reliable steel Sapim j-bend spokes, which not only adds strength to the wheels but also makes spoke replacement simple and easily sourced should you go rubber-side up on the a-line.
