Stem FSA NS ACR 31.8 -6°

The FSA NS ACR stem is designed for modern road and gravel bikes that support fully internal cable routing. The ACR system routes all cables through the stem and headset, creating a clean look and improved aerodynamics.

Its low-profile frontal area reduces drag, while the -6° angle supports a sporty riding position. The absence of a rotation limit ensures unrestricted steering control.

Constructed from durable 6061 T6 aluminum, the stem features a secure four-bolt faceplate and Chromoly hardware. A dedicated ACR headset spacer kit is included for proper installation on compatible frames.
