OneUp Components Stem

The OneUp Components Stem is a precision-engineered cockpit upgrade designed to deliver confidence, control, and durability across a wide range of mountain biking disciplines. From aggressive trail riding and all-mountain adventures to enduro racing and freeride sessions, this stem combines strength, low weight, and refined aesthetics to create a dependable connection between rider and bike.

Machined from premium 6061-T6 aluminum, the OneUp Stem is built to withstand the demands of modern mountain biking while maintaining an impressively lightweight profile. Its efficient use of material creates clean, purposeful lines that not only contribute to its sleek appearance but also provide the structural integrity needed for hard charging on technical terrain.

Available in 35mm, 42mm, and 50mm lengths, riders can choose the fit and handling characteristics that best suit their riding style and bike geometry. The short lengths promote responsive steering and precise front-end control, making the stem particularly well-suited to modern trail and enduro bikes. With a 0° rise and 39mm stack height, it delivers a balanced cockpit position that complements today's progressive frame designs.

The wide 55mm handlebar clamp evenly distributes clamping force for enhanced security and compatibility with modern 35mm handlebars. While specifically designed to pair seamlessly with the OneUp Carbon Handlebar and OneUp Carbon E-Bar, the stem is fully compatible with any standard 35mm diameter handlebar, making it a versatile option for a wide variety of bike builds.

Attention to detail extends throughout the design, from the clean machining and black finish to the pre-installed hardware that simplifies installation. Whether upgrading an existing cockpit or completing a new build, the OneUp Stem delivers the performance, reliability, and refined styling riders expect from OneUp Components.

The OneUp Components Stem is a lightweight and durable mountain bike stem designed to provide precise steering, confident control, and seamless compatibility with modern 35mm handlebars.
