Product details

Stem for 2 handlebar diameters - The Black One Direct Mount D-2 revolutionizes your downhill bike. As the successor to the legendary Black One Direct Mount stem, this innovative design finally allows for riding with both common diameters. The included reducer sleeve enables the use of handlebars with a diameter of 31.8 mm. By removing the sleeve, you get a 35 mm stem - flexible and adaptable.

The sleek design integrates seamlessly into your cockpit, giving it a tidy appearance. The two-part design of the stem and reducer sleeve allows for effortless handlebar installation without the need to disassemble existing components like brakes or grips.

The intelligent and seamless clamp design at the bottom ensures that there are no pinch points or sharp edges. Instead, the clamping forces are evenly distributed, enhancing safety and creating optimal technical conditions, especially for carbon handlebars. This is particularly important as most stresses and notch effects occur at the lower part of the handlebars. Additionally, our smooth and seamless clamping surface extends the lifespan of your handlebars.

The stem is certified according to the E-Safety Level with category 5 (maximum) and has successfully passed the EFBE E-MTB Tri Test. This guarantees the highest safety and quality for your riding experience. Experience flexibility and performance with the Black One Direct Mount D-2 stem.
