FSA Vision NS SMR Stem

The SMR (Smart Cable Routing) system allows you to route your brake hoses and shift cables directly from the handlebar, through the stem, and into the frame. This eliminates exposed cables at the front of the bike, resulting in a cleaner aesthetic and improved aerodynamics.

Yes, the SMR stem is designed to accommodate mechanical shifting, electronic shifting, and hydraulic braking systems. It is built to handle the routing requirements of all three, provided your frame and handlebar are also compatible with internal routing.

Yes, it is designed for a standard 28.6mm (1-1/8 inch) steerer tube. It also features a 31.8mm handlebar clamp, which is the industry standard for most modern road and gravel handlebars.

The stem weighs 268 grams. While it is constructed from durable 3D forged and CNC-machined aluminum, its weight reflects the robust internal routing channels, making it a reliable choice for road and gravel racing where stiffness and clean cable management are priorities.

The stack height is 33.5mm. You should ensure your steerer tube has enough length to accommodate this specific measurement, as it may differ slightly from your current stem, potentially requiring you to adjust your headset spacers.
