Why We Like The A35 Stem

We've been riding and admiring Industry Nine's high-end wheels for years, so when we saw that they released a mountain bike stem with the same striking anodized colorways as their hubs, we were excited to say the least. We're happy to present the A35 Stem, named after the A-axis in I9's five-axis CNC machining centers. And like their revered hubs, the A35 Stem performs as good as it looks. Industry Nine designed it to be as stiff as possible while still coming in at a competitive weight, all while upholding their rigorous manufacturing and testing standards. They even went so far as to build an in-house stem and handlebar testing unit and design a testing protocol that exceeds the ISO standard for stems, demonstrating their commitment to quality.


The A35 Stem is machined, anodized, and assembled entirely in-house at I9's Asheville, North Carolina manufacturing facility. It's made from a solid billet of high-grade 7075 aluminum which offers superior strength to the 6061 aluminum more commonly found on mountain bike stems. The bolts are high-strength stainless steel to match the integrity of the stem. It's available in 11 anodized colors, and four different lengths ranging from a stubby 32mm all the way up to 60mm. It's designed to fit 35mm diameter handlebars, which seems to be the standard most handlebar companies are going with for aggressive all-mountain riding.

It's VERY pink

Familiarity:
I've used it several times

Look, it's a stem, there's not a lot going on here. My handlebar has remained attached to my steerer, it's reasonably light for the category, and it's made in the USA. The important part is that the color is every bit as vibrant as the pictures. No washed out or faded anodizing here.

Good quality bling

Familiarity:
I've used it several times

Nice out of the box fit and finish. Lighter than stock. Nice rise or drop feature. Stainless steel bolts-it's really humid in Louisiana so it's a nice feature. Bling. Not zero gap, but it's not a huge issue.

Stiff and short

Familiarity:
I've put it through the wringer

Great stem, went short and really livened up the steering. Made in the USA, quality product!

7075 Aluminum is a high-strength alloy known for its durability and lightweight properties, making it ideal for mountain bike components. Its unique composition, primarily featuring zinc, provides superior strength compared to other aluminum alloys like 6061. This means that parts made from 7075 Aluminum can withstand the rigors of off-road biking, ensuring better performance and longevity.

316 Stainless Steel is highly resistant to corrosion, making it perfect for bike components exposed to harsh environments, such as moisture and saltwater. The inclusion of molybdenum in its composition gives it enhanced resistance compared to other stainless steels. This means that parts made from 316 Stainless Steel will last longer and require less maintenance, providing peace of mind for riders.

Anodized colors are achieved through an electrochemical process that not only adds aesthetic appeal to bike components but also enhances their durability. The anodizing process creates a protective layer on the metal surface, making it more resistant to scratches, corrosion, and fading. This means your bike will not only look great but also maintain its finish over time, even in tough riding conditions.

CNC machining stands for Computer Numerical Control machining, a process that uses computer technology to precisely control machine tools. This method allows for high precision and consistency in manufacturing bike parts, ensuring that each component meets strict quality standards. As a result, bike parts made with CNC machining are more reliable and perform better, giving you confidence on the trails.

ISO standards are international benchmarks that ensure products meet specific safety and performance criteria. For mountain bike stems, adhering to these standards means that the components have been rigorously tested for quality and reliability. Choosing products that exceed ISO standards indicates a commitment to superior design and safety, which is crucial for your riding experience.

The materials used in bike components, such as 7075 Aluminum and 316 Stainless Steel, directly impact the bike's weight, strength, and durability. Lightweight materials improve handling and speed, while strong, corrosion-resistant materials enhance longevity and performance. By selecting high-quality materials, you can enjoy a smoother, more reliable ride, allowing you to focus on the adventure ahead.
