Description
The Reverse Components Black-One D-2 Direct Mount stem revolutionises the cockpit of downhill (DH) and freeride bikes with its innovative D-2 (1 Stem – 2 Diameters) technology. Fitted with a removable aluminium reducer shim, it fits handlebars with diameters of Ø 31.8 mm and Ø 35.0 mm, allowing you to upgrade or change your handlebars without replacing the stem.
Its two-piece CNC-machined 6061-T6 aluminium construction ensures a seamless appearance and makes installation easier without removing the grips. Thanks to its smooth, continuous lower clamping surface, clamping forces are distributed evenly to eliminate stress points, protecting the carbon handlebars and extending their lifespan.
