Smooth, aerodynamic, responsive--we want these things from our ride, and the S-Works Future Stem works in tandem with the all-new Roubaix to do just that. Stiff and lightweight, the Future Stem delivers a responsive handling and feel whether you're riding long coastal trails or tight, tree-lined routes closer to home. It integrates seamlessly with all Future Shocks and can fit some older Roubaix models when using it in tandem with the correct shim.
