A318 Stem delivers stiff, precision handling with a limited 20th Anniversary finish
What Our Gearhead® Experts Are Saying:
"I’ve run the A318 Stem for years, but the 20th Anniversary edition is extra special. Same legendary stiffness and machining, now in a finish that stands out on any build. It’s a reminder that a stem can be both bombproof and beautiful."
Two decades of craftsmanship meet modern trail performance in the Industry Nine A318 Stem. To celebrate 20 years of precision machining in Asheville, I9 released a limited Anniversary colorway that makes this proven stem feel like a true centerpiece on the bike.
Beyond its striking finish, the A318 is all about performance. It’s machined from a solid billet of 7075 aluminum, strength-tested far beyond industry standards, and finished with burly stainless steel hardware for years of hard riding. Whether we’re building up a fresh rig or upgrading an old favorite, this stem adds both rock-solid control and a flash of commemorative style that marks two decades of I9 innovation.
