1 stem for 2 handlebar diameters.
The Black One D-2 stem builds on the success of the flagship, the Black One Enduro stem and offers the possibility to ride both 31.8mm and 35mm diameter handlebars with one stem. The specially designed reducing bush allows the use of 31.8mm handlebars and when removed, you get a 35mm stem. It offers a wide, smooth clamping area, which is ideal for the use of carbon handlebars.

The intelligent and gap-free clamping design in the lower area ensures that there are no pinch points or sharp edges and that the clamping forces are evenly distributed. This ensures safety and optimal technical conditions. This is because most loads and notch effects are always at the bottom of the handlebars. A smooth, gap-free clamping surface extends the life of your handlebars.


Increasingly higher loads must be absorbed by the components, because the frequency of rides with a E-Bike is significantly higher than without a motor. Rides that were done once in the pre-e-bike era are now done three times with motor support. Therefore, the cockpits of modern e-bikes must be able to withstand more than on conventional bikes.

With the stems of the E-series Reverse Components has reacted to exactly this development. The E-Black One D-2 stem was tested in the EFBE test laboratory according to the "EFBE EPAC MTB-GR Tri-Test", which is one of the toughest test procedures worldwide, and passed all tests without any problems!

Tested and certified in Germany, this stem can be fitted to any e-bike without hesitation and convinces with its design and stability!
