The Enve Aero Road Stem is an aerodynamically honed stem with adjustable length and angle to optimize your position. Linking handlebar to fork, the stem was developed for the refined ride response and control needed in a critical area of the bike. This stem is intended for negative drop only and cannot be flipped or reversed in a positive rise. The shape of the stem, plus the ability to eliminate headset spacers, allows for cleaner airflow at the front of the bike, producing valuable drag savings. The Enve Aero Road Stem delivers the confident and responsive ride feel desired by the best riders in the world.
