The standard Deda Zero100 Stem is identical in nearly every detail to the Zero100 Servizio Corse. It's made with the same ultra-light 2014 aluminum alloy construction and with the same 3D forging to maximize the wall thinness (and thereby shave weight). The only distinction, in fact, is that the Zero100 foregoes the titanium bolts that come standard on the Servizio Corse model. Instead, it has stainless steel bolts. For this slight hardware modification, you save nearly 50% in cost.
Like the Servizio Corse model, the standard Zero100 is available in 10mm increments from 90mm-130mm and has the standard 82 degree rise seen on almost all Deda stems. It comes in a 31.7mm clamp size only, and is available in two colors -- the same matte black we've all become familiar with on the Deda Newton, and a "Dark Metal Polish" we refer to as grey.
The actual weights of the Deda Zero 100 Stem: 90mm is 118g. 100mm is 121g. 110mm is 129g. 120mm is 133g. 130mm is 136g.
