A318 Mountain Stem

Industry Nine’s A-Series mountain bike stems are crafted from USA-sourced 7075 aluminium billets into a svelte design, achieving a nexus of form and function. Using advanced manufacturing techniques honed over decades in our CNC machine shop, I9 continue their proud tradition of offering riders uncompromising components.

Taking name and shape from the A-axis in I9's five-axis machining centres, the A318 and A35 and A318 are destined for your favourite all-mountain rides. The A35 and A318 utilize either a 35 mm or 31.8 mm handlebar clamp diameter, providing 180 degrees of contact on the stem body for twist-free security that will play nice with both alloy and carbon bars. Stainless steel hardware ensures everything stays in place and looks great, regardless of mud-blasting washes or rainforest climates.

Every A-Series stem is machined, anodized and assembled entirely in Industry 9's Asheville, NC facility and available in a variety of lengths geared for modern trail bike geometry. Add an expressive mix of 11 anodized colours, and you’ve arrived at the intersection of execution and desire.
