What Our Gearhead(R) Experts Are Saying:"I've installed the CenterLine X on both road and trail builds where riders want lighter weight without sacrificing braking feel. The two-piece design keeps things responsive, and it runs noticeably quiet on long descents. It's an easy upgrade if you're trimming weight but still want reliable stopping power."Whether we're carving fast pavement descents or managing speed on technical singletrack, braking consistency shapes our confidence. The CenterLine X Rotor from SRAM gives us smooth, predictable control in a lighter two-piece design that feels refined under pressure. Built with an alloy carrier and a steel brake track, the CenterLine X Rotor reduces rotational weight while maintaining durability where it matters most. The CenterLine braking surface is engineered for quiet, consistent engagement, minimizing vibration and enhancing modulation. Rounded edges simplify wheel installation and meet race compliance standards, while compatibility with both road and mountain brake systems makes it an adaptable choice across builds.
