FSA SMR ACR Stem

ACR stands for Aerodynamic Cable Routing. This system is designed to route your brake and shift cables internally through the stem and headset, creating a cleaner, more aerodynamic cockpit by hiding the lines from the wind.

Not necessarily. Because the SMR ACR stem is designed for internal cable routing, your frame and headset must be compatible with an integrated routing system. It is best suited for modern road and gravel builds specifically engineered to accept internal cable entry.

Yes, as long as your handlebars have a 31.8 mm clamp diameter. However, for the cleanest look and easiest installation, you may want to pair this with handlebars that also support internal cable routing, though it is not strictly required.

A 6-degree angle is a standard, versatile choice for road and gravel bikes. It allows you to flip the stem to either a slight rise or a slight drop, helping you fine-tune your handlebar height for a balance between comfort and an aggressive, aerodynamic posture.

Absolutely. The alloy construction is chosen specifically for its balance of stiffness and durability, making it well-suited to handle the vibrations and varied terrain of gravel riding while maintaining precise steering control.
