XLC ST-M15 A-Head Bicycle Stem

The XLC Comp A-Head ST-M15 25.4 mm Stem is a high-performance component designed to improve steering precision and comfort on MTB and trekking setups. Crafted from 3D forged high-strength 6061 aluminum, it offers a rigid, lightweight connection between your handlebars and fork. A four-bolt faceplate provides secure clamping for 25.4 mm handlebars, while multiple angle options allow you to choose an aggressive or upright riding stance to reduce strain on long rides. The stem is designed for modern A-Head (threadless) forks and features a sleek sandblasted black finish. While easy to install and robust in performance, its height may be too tall for some bike configurations, so it’s important to verify fit for your specific frame and cockpit.
