FSA SMR to ACR Cone Spacer

This spacer acts as a structural bridge between FSA's SMR (Smart Cable Routing) and ACR (Aerodynamic Cable Routing) headset systems. It ensures a clean, flush transition between your headset and stem while maintaining the necessary alignment for internal cable routing.

This spacer is designed specifically for standard 1-1/8 inch fork steerers. As long as your fork meets this standard and you are utilizing an FSA SMR or ACR compatible cockpit, it will be compatible.

No specialized tools are required beyond standard hex keys for your stem and headset adjustments. However, because it is a precision component for internal routing, ensure your cables are properly seated before tightening the stem to avoid pinching or binding.

This component is engineered specifically to interface with FSA's proprietary SMR and ACR systems. It is not designed to work with standard stems or other brands' integrated routing systems, as the geometry is unique to FSA's specific cable routing interface.

Alloy is used here to ensure maximum structural integrity and durability at the headset interface. Since this part handles the compression and steering forces of the cockpit, the alloy construction provides a reliable, rigid platform that won't deform under the torque required for a secure headset setup.
