Stem for 2 Handlebar Diameters

The Black One D-2 stem builds on the success of the flagship Reverse Black One Enduro stem and offers the option to use handlebars with both Ø31.8 mm and Ø35 mm diameters. 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 features 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 distributed evenly. This provides safety and optimal technical conditions, as most loads and notch effects always occur at the bottom of the handlebar. The smooth, gap-free clamping surface of Reverse extends the lifespan of your handlebar.

The Black One D-2 is perfect for riders who want the option 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.
