Deda Zero100 Performance Stem
The Zero100 stem is made from 2014 aluminium alloy. Deda uses their proprietary 3D forging method to maximize the durability of the alloy (forging preserves the structure of an alloy to a greater extent than CNC machined alloy). The 3D process uses a special lubricant in the mould during the forging process that allows them to keep the stem walls supremely thin -- varying from 1.5mm all the way down to 1.1mm. The thin walls bring one central benefit: ultra-lightness. The Zero100 rivals the weight of any carbon fibre stem in the market.
