Your new Mountain stem.

Just the way you want it.

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

Taking name and shape from the A-axis in our five-axis machining centers, the A35 and A318 are destined for your favorite all-mountain rides. The A35 and A318 utilize either a 35mm or 31.8mm 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.
