The Black One D-2 stem is based on the success of our flagship product, the Black One Enduro stem, and offers the option to use handlebars with a diameter of 31.8 mm as well as 35 mm.

The specially designed reducing sleeve allows for the use of 31.8 mm handlebars, and when removed, it provides a 35 mm stem. The reducing sleeve features a wide, smooth clamping area that is ideal for use with carbon handlebars.

The intelligent and gap-free clamping design at the bottom ensures that there are no pinch points or sharp edges, and the clamping forces are evenly distributed. This guarantees safety and optimal technical conditions, as most stresses and notch effects occur at the lower end of the handlebars. Our smooth, gap-free clamping surface extends the lifespan of your handlebars.

The Black One D-2 is perfect for riders who want to use both 31.8 mm and 35 mm handlebars or who may want to switch to a new handlebar in the future without needing to purchase another stem.
