The Controltech ONE Stem is the gold standard for cyclists who value a perfect blend of responsive handling, lightweight durability, and versatile fit. Whether you're racing on tarmac, grinding through cyclocross mud, or threading mountain trails, this stem is built to deliver uncompromising performance with every turn of the bars.

Constructed using 3D forged AL6061 aluminum, the ONE Stem offers a superior strength-to-weight ratio that outperforms traditional cast designs. The 3D forging process ensures grain alignment within the metal structure, significantly enhancing its integrity while allowing for thinner wall thicknesses. The result? A stem that is both exceptionally stiff and impressively light, reducing unnecessary grams without compromising control or reliability.

Every detail of the Controltech ONE is optimized for rider performance. The faceplate, also made from 6061 aluminum, adds an extra layer of strength and resilience, giving the stem an overall structural integrity close to that of steel—but without the weight penalty. This combination makes the stem ideal for high-stress situations such as sprinting, descending, or aggressive off-road riding, where confident bar control is non-negotiable.

With a +/- 5º flip angle, the stem can be easily mounted in a rise or drop configuration, depending on your fit preference or riding discipline. Choose a positive angle for a more upright, endurance-oriented setup, or flip it for an aggressive, aero-optimized position on your road or race bike. This dual-fit adaptability empowers you to fine-tune your cockpit without changing core components.

The ONE Stem is available in extension lengths ranging from 60mm to 130mm, giving riders across all sizes and geometries the chance to find their ideal fit. Proper stem length is critical not just for comfort, but for optimal weight distribution and precise steering—key factors in both road stability and off-road maneuverability.

Designed to fit standard 28.6mm steerer tubes and 31.8mm handlebars, the stem integrates seamlessly into most modern bikes, offering maximum compatibility without compromising performance. A stack height of 40mm ensures it seats confidently without requiring excessive spacers, keeping your front-end setup clean and functional.

Despite its rugged construction and engineering pedigree, the ONE Stem is featherlight—tipping the scales at just 121 grams (90mm length). That makes it an ideal upgrade for weight-conscious riders seeking every marginal gain, without sacrificing the rigidity needed for confident sprinting or aggressive descending.

Finished in a sleek sandblasted anodized black, the stem resists scratches, corrosion, and glare—offering a durable and stylish accent to any high-performance cockpit.

Whether you're fine-tuning your road geometry, dialing in your mountain bike control, or building a race-ready cyclocross rig, the Controltech ONE Stem delivers elite performance, millimeter-perfect fit, and unshakable strength—ride after ride.

Control, comfort, and clean aesthetics—compressed into a stem that’s as strong as it is smart.
