Reverse Stem Black-ONE

A stem, two handlebar diameters! The Black-ONE D-2 Direct Mount stem is the ideal solution for modern downhill mountain bikes.

With its included reducer ring, it is compatible with handlebars of Ø31.8 mm. Once the ring is removed, it fits handlebars of Ø35 mm. Practical and adaptable, it allows for quick installation without removing the controls (brakes, grips).

Its CNC machined design ensures even clamping without pressure points or sharp angles, extending the lifespan of the handlebars, especially carbon ones.

Certified E-Safety Level 5 (maximum) and validated by the EFBE E-MTB Tri Test, this stem guarantees strength and reliability, even on the most demanding electric mountain bikes.
