Profile Design Road Stem - 31.8mm | 1 1/8" | -6° - black

The Road Stem combines lightweight construction, aerodynamic styling, and reliable stiffness to create a clean, integrated cockpit for modern road bikes. Designed to pair seamlessly with the Profile Design Canta Race, Drive Aero C, and other handlebars featuring a 31.8mm clamp diameter, it delivers a sleek front end that looks as fast as it performs.

Engineered for versatility, the stem supports both internal and external cable routing. When paired with the appropriate headset system, it enables a fully integrated setup that's ideal for electronic drivetrains and hydraulic disc brakes, while also remaining compatible with traditional external routing for maximum flexibility.

Designed for internal or external cable routing

Precision 3D-forged from premium 6061-T6 aluminum, the Road Stem offers an excellent balance of stiffness, strength, and low weight for confident handling and efficient power transfer. Its aerodynamic flat profile helps create a cleaner airflow at the front of the bike, while the understated matte black finish with subtle black graphics complements virtually any road build.

3D forged alloy construction for optimal stiffness and weight

Complete with an integrated top cap and compatibility with standard 1 1/8-inch steerer tubes, the Road Stem is the perfect finishing touch for riders seeking a clean, modern cockpit without compromising performance.
