FSA ACR Cone Spacer - Colnago C68/V4Rs

The FSA ACR Cone Spacer – Colnago C68/V4Rs is a specialized cockpit integration component designed to support modern fully internal cable routing systems on Colnago’s flagship performance frames. Developed as part of FSA’s ACR (Aerodynamic Cable Routing) platform, this cone spacer helps create a seamless transition between the headset, frame, and integrated cockpit while guiding cables cleanly through the front end of the bike.

High-performance road bikes like the Colnago C68 and V4Rs rely on advanced internal routing systems to reduce aerodynamic drag and deliver a clean, streamlined appearance. The FSA ACR system allows brake hoses and electronic shift wires to pass internally through the handlebar, stem, and headset before entering the frame. The cone spacer plays a critical role in this architecture by maintaining the correct spacing and alignment while allowing cables to move smoothly through the headset area.

Specifically shaped for compatibility with the Colnago C68 and V4Rs platforms, this spacer ensures a precise fit within the headset assembly while preserving the aerodynamic design of the bike’s front end. Its tapered profile allows the cockpit spacers and stem to integrate cleanly with the frame, maintaining the sleek lines that define Colnago’s modern race bikes.

The component is constructed from lightweight, durable materials designed to withstand the stresses of high-performance road riding without adding unnecessary weight. Precision manufacturing ensures accurate tolerances so the headset system maintains proper preload and smooth steering performance.

Whether building a new bike or servicing the integrated cockpit system, the FSA ACR Cone Spacer ensures that internal cable routing functions correctly while preserving the clean aesthetic and aerodynamic advantages of the Colnago C68 and V4Rs platforms.
