Stem for 2 handlebar diameters. The Black One D-2 stem builds on the success of our flagship product, the Black One Enduro stem, and offers the option to use both Ø31.8 mm and Ø35 mm diameter handlebars.

The D-2 Titanium features the same design as the D-2 stem but with additional precision machining, a glossy black finish, and titanium screws, reducing the weight to just 127 g while maintaining strength under full load.

The specially designed reducing sleeve allows for the use of Ø31.8 mm handlebars, and when removed, it provides a Ø35 mm stem. The reducing sleeve offers a wide, smooth clamping area, making it 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 in the lower handlebar area. Our smooth, gap-free clamping surface extends the lifespan of your handlebars.

The Black One D-2 is ideal for riders who want the flexibility to use both Ø31.8 mm and Ø35 mm handlebars or may want to switch to a new handlebar in the future without needing to purchase another stem.
