Description:
A masterpiece of early 1980s aerodynamic bicycle design, the Shimano 600 AX HS-7300 quill stem revolutionized front-end airflow. Engineered with an entirely smooth, wind-cheating teardrop profile, it utilizes an ingenious internal wedge mechanism that clamps both the handlebar and quill without exposed exterior bolt heads. With its 110 mm reach and proprietary 26.6 mm clamp designed specifically for AX-series aerodynamic bars, this stem represents a futuristic milestone of vintage Japanese design and a prized component for aerodynamic period builds.
