The success of Enve\'s carbon parts relies on our ability to precisely machine the aluminum and steel molds in which their carbon rims and components are made. In fact, they\'ve been machining aluminum and steel long before they 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.Their 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.COLD-FORGED AND PRECISION MACHINEDCold-forged and precision machined for maximum strength and weight savings. Cold-forging is a process of smashing a block of raw aluminum billet into a shape. This process increases strength and reliability of the part by aligning the grain structure of the alloy. Following this process, the forging is then machined to its final shape.NO GAP FACE PLATE AND CLAMP AREANo gap face plate and clamp area – Ensures even clamping and secure handlebar retention. Clamp area features beveled edges to prevent scoring of sensitive carbon handlebar laminates.STAINLESS HARDWAREStainless hardware – M5 stainless steel hardware ensures reliable corrosion free performance over the long haul.Product SpecificationsMaterial: AluminumLength: 35mm / 50mm / 65mmRise: 0 DegreesSteerer Clamp Diameter : 31.8mmFaceplate Material: AluminiumHardware Material: AluminiumStack Height: 40mmTorque Spec Faceplate: 5.5NmTorque Spec Steerer Tube: 5.5NmWeight: 115g (35mm) 160g (50mm) 160g (65mm)
