ENVE Alloy Mountain Stem (31.8mm)

A 3D-forged then precision machined lightweight aluminum mountain bike stem in both 31.8mm and 35.0mm models rated for cross country, trail, all-mountain, enduro and gravity applications.


We are carbon experts, but that doesn’t mean we don’t know our way around aluminum as well. The success of our carbon parts relies on our ability to precisely machine the aluminum and steel molds in which our carbon rims and components are made. In fact, we’ve been machining aluminum and steel long before we ever pulled a carbon part from a mold. Accuracy, precision, and durability are key components to making an aluminum mold for carbon parts, and they just so happen to be the same ingredients required for making a premium grade aluminum mountain bike stem.

Our goal for the Alloy Mountain Stem was a product defined by strength, light-weight, ride quality and aesthetics that honor the art of machining aluminum while preserving as many of the performance benefits of our carbon M Series Handlebars. To achieve this, each alloy stem is cold-forged, and then extensively machined.

The result is an incredibly strong and reliable stem, at only a slight weight penalty to carbon, but lighter than most premium alloy stems on the market. Given that stems and handlebars function as a team, the Alloy Mountain Stem’s clamp width is designed to complement M Series carbon handlebars and their unique flex profiles. To further perfect the pairing, the surfaces of the stem’s clamp area are refined to prevent damage to our M Series carbon handlebars. Additionally, the Alloy Mountain Stem features blind bolt holes to prevent sharp edges and battered knees. Finally, stainless steel hardware is used to achieve hard wearing durability without the risk of corrosion.

The ENVE Alloy Mountain Stem is designed to deliver a more affordable alternative to the ENVE M6 & M7 Carbon Stems while at the same time giving you the rider, confidence.
