XLC A-head stem ST-M15 ø 31.8 mm 90 mm 35° black

From XLC, the Comp A-Head Stem ST-M15 is a clean, technical finishing piece designed for A-head set-ups. Made from Aluminium 6061 and 3D forged, it offers a considered balance of strength and a streamlined look, finished in black for easy pairing across a wide range of bike builds.

With a 35° angle and a 90 mm length, it’s a precise option when you want to refine your cockpit position. A 42 mm clamp mounting height (at 35°) completes the profile, while the approximate 145 g weight keeps the overall build feeling light and responsive.
