Tune stem Geiles Teil 4.0. Its conical shape—inside and out—follows the load path precisely, delivering excellent stiffness and stability. Suitable for road, gravel, and MTB, designed for 31.8 mm handlebars (carbon or alloy). Add some color! Available in all tune anodized colors.
Installation note: The stem can technically be flipped, but our laser marking is aligned for the downward (negative angle) position—that’s how it looks best.
