The Industry Nine Sector Carbon wheel pairs a WR1 Convergence carbon rim with an articulating spoke bed to keep power transfer consistent on the punchy, technical climbs that define trail riding. At 29mm internal width, the rim supports a wide trail tire profile without ballooning the sidewall, and the carbon layup holds its shape through repeated compression on rocky, root-strewn terrain. What Our Gearhead(R) Experts Are Saying:"I've stood up out of the saddle on a loose, rooty climb and felt the rear end respond the instant I put power down, with no flex eating into that effort. That immediacy is what a stiffer carbon rim gives back on the steep stuff."
