Description
Industry Nine’s A-Series stem brings precision, strength, and craftsmanship together in a compact all-mountain package. Machined in Asheville, NC from domestically sourced 7075-aluminum billet, this stem embodies I9’s signature blend of clean design, tight tolerances, and uncompromising performance. The result is a sleek, trail-ready stem built to inspire confidence on technical terrain while keeping handling crisp and responsive.
This version features a 31.8mm clamp diameter and a 50mm length, delivering balanced steering feel for everything from fast trail rides to aggressive all-mountain lines. A 180-degree bar clamp provides secure, twist-free grip on both aluminum and carbon handlebars, while stainless-steel hardware ensures long-lasting durability through mud, rain, and repeated wash-downs.
Proudly machined, anodized, and assembled in the USA, the A-Series is a premium upgrade for riders who demand quality in every detail.
