Industry Nine’s A-Series stems are crafted from aluminum billet into a svelte design of equal form and function. Using practices honed in their machine shop over a decade of CNC manufacturing, they offer the rider another unyielding Industry Nine component.
Taking name and shape from the A-axis in their five-axis machining centers, the A318 is designed for all-mountain applications. The A318 utilizes a 31.8mm handlebar clamp diameter.
Every A-Series stem is machined, anodized, and assembled entirely in Industry Nine's Asheville, NC facility and available in a variety of lengths geared for modern trail bike geometry.
