REVERSE stem Black-One D-2

REVERSE Stem Black-One D-2

The Black One D-2 stem builds on the success of Reverse's flagship Black One Enduro stem, offering the ability to use both 31.8 mm and 35 mm diameter handlebars with a single stem. The specially designed reducer sleeve allows the use of 31.8 mm handlebars, and removing it creates a 35 mm stem. The reducer sleeve provides a wide, smooth clamping area, ideal for use with carbon handlebars.

The D-2 Titanium has the same design as the D-2 stem with additional precision machining, a glossy black or silver finish and titanium screws, reducing the weight to a low 127g while maintaining strength at full load capacity.

The intelligent, gap-free clamping design at the bottom ensures there are no pinch points or sharp edges, and that clamping forces are evenly distributed. This guarantees safety and optimal performance, as most stresses and notch effects are always concentrated at the bottom of the handlebar. The smooth, gap-free clamping surface also extends the lifespan of your handlebars.

The Black One D-2 is ideal for riders who like to have the option of using both 31.8 and 35 mm handlebars, or who might want to switch to a new handlebar in the future without having to buy another stem.
Available in 35 mm and 50 mm lengths.
