Introducing the Controltech ONE Stem, a pinnacle of engineering finesse where strength, weight, and performance align seamlessly. Designed for elite cyclists and ambitious riders alike, this stem delivers the structural integrity, ergonomic flexibility, and minimalist aesthetic demanded by modern cycling disciplines—from high-octane road racing to gravel-grinding cyclocross.

At its core, the ONE Stem is constructed from 3D forged AL6061 aluminum—a process that goes beyond traditional casting by shaping the metal under extreme pressure to refine its grain structure. The result is a stem that is not only significantly stronger but also lighter and stiffer, offering superior control with every turn of the handlebars. This advanced construction allows for reduced wall thickness without compromising safety or durability, making it a true performance upgrade for any cockpit.

Adding to its robustness, the faceplate is also forged from AL6061, delivering strength comparable to steel while keeping weight impressively low. This ensures that even under extreme torque—whether from sprint efforts, technical descents, or rough off-road conditions—your handlebar interface remains rock solid and responsive.

The Controltech ONE Stem is designed with a +/- 5° reversible rise/drop, providing versatile fit options tailored to your riding goals. Flip it for a lower, more aerodynamic position to slice through the wind, or keep it upright for a relaxed, endurance-focused posture—ideal for sportive rides, all-day tours, or variable terrain.

Recognizing the importance of precise bike fit, the ONE Stem comes in multiple extension lengths from 60mm to 120mm, allowing every rider to fine-tune reach and handling characteristics for optimal comfort and efficiency. The correct stem length plays a critical role in weight distribution, steering response, and overall ride feel—this stem ensures you can dial it in to perfection.

Compatibility is no issue—this stem is engineered to fit 28.6mm steerer tubes and 31.8mm handlebars, the standard for modern road, MTB, and gravel bikes. Its 40mm stack height ensures a secure fitment on your steerer tube without excess bulk, while the SCM-435 bolts offer high tensile strength and reliability for secure clamping under pressure.

Despite its formidable build, the ONE Stem remains exceptionally light, tipping the scale at just 121 grams (90mm length)—making it a choice pick for weight-conscious cyclists building competitive machines without sacrificing control or stiffness.

Aesthetically, the sandblasted anodized black finish offers a sleek, stealthy appearance that resists wear, corrosion, and UV fading—making the stem as enduring in looks as it is in structure.

Whether you're chasing seconds on the road, carving corners off-road, or searching for all-day comfort in mixed conditions, the Controltech ONE Stem delivers confidence, customization, and uncompromising performance in a clean, modern form.
