Description
Based on the brand’s iconic Enduro model, the Reverse Components Black-One D-2 35 mm stem features patented D-2 (1 Stem – 2 Diameters) technology. Thanks to its high-precision removable reducer shim, it accommodates handlebars with a diameter of either Ø 31.8 mm or Ø 35.0 mm, giving you complete flexibility to upgrade your cockpit without changing the stem.
Machined from 6061-T6 aluminium, this ultra-short 35 mm version responds instantly to steering inputs while keeping weight down. Its continuous lower clamping area (no-gap design) distributes stress evenly, eliminating sharp edges and protecting the structure of carbon handlebars. Certified to the highest safety level (Category 5), it is ideal for demanding enduro riding, downhill and electric mountain biking.
