Description

A318 Stem

Industry Nine has been making world-class cycling components in their Asheville, North Carolina machine shop for over a decade. Their A-series stems are crafted from a solid billet of high-grade 7075 aluminum, and are available in a variety of lengths well-suited to modern trail bike geometry. They're designed to be as strong and stiff as possible while maintaining a competitive weight, and they far exceed the ISO standard testing protocol for mountain bike stems, demonstrating I9's unwavering commitment to quality.

The A318 Stem is machined, anodized, and assembled entirely in-house at I9's Asheville, North Carolina manufacturing facility. The 7075 aluminum construction offers superior strength to the 6061 aluminum more commonly found on mountain bike stems, and the bolts are high-strength stainless steel to match the integrity of the stem. It's available in 11 anodized colors, and as the name implies, is designed to fit handlebars with a 31.8mm diameter.

    excellent quality

    Familiarity:
    I've used it several times
    Fit:
    True to size

    it might be slightly heavier than my stock stem but I love the fit and finish. the color (orange) looks great on my bike and it really makes the bike look nicer. it makes the bike mine. it feels really sturdy and solid on the ride.
