ENVE Composites Alloy 31.8 Mountain Stem

ENVE's 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 the 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.
