The Deda Zero1 Stem pairs directly with Deda's Zero1 handlebar range, sharing the same design philosophy: functional, strong, and free of anything unnecessary. Its extension uses a 3D forged triangular tube profile — the same geometry found on Deda's higher-tier stems — which delivers meaningful torsional stiffness without adding bulk. The result is a stem that holds its position under hard efforts and doesn't flex when you're sprinting out of the saddle. The 82-degree angle suits a wide range of road setups, and the seven available lengths — from 70mm to 130mm in 10mm increments — make it easy to dial in your reach regardless of how your bike fits. Two finish options are available: Black on Black (matte) and Black glossy anodized, both clean enough to complement most builds without calling attention to themselves. At 145g for the 110mm length, the Zero1 sits comfortably in the lightweight bracket for a stem at this level.
