FSA

ACR Spacer, 5mm Height, Headset Spacer for ACR System – Black

The FSA ACR Spacer is a lightweight headset spacer designed specifically for FSA’s ACR (Aerodynamic Cable Routing) system. ACR is FSA’s fully internal routing standard, allowing brake hoses and shift housing to pass cleanly through the headset and stem for a streamlined cockpit. This 5mm spacer helps fine-tune stack height while maintaining proper internal cable alignment.

Unlike SMR, which offers both semi-integrated and fully internal routing options, ACR is focused on complete internal integration and requires compatible headset and stem components. This spacer is molded from durable nylon to reduce weight while providing precise spacing and reliable fit.
Features

• Designed for FSA ACR fully internal cable routing systems
• 5mm stack height for fine cockpit and fit adjustment
• Molded nylon construction for lightweight performance
• Maintains proper cable alignment through the headset
• Compatible with standard 1-1/8” steerers when used in ACR setups

Recommended Use
For bikes equipped with FSA ACR headsets and stems where clean internal cable routing and precise stack adjustment are required.
