FSA NO.55R Headset

ICR stands for Integrated Cable Routing. This headset is specifically designed to allow brake hoses and shift cables to pass through the headset assembly and into the frame, resulting in a cleaner cockpit and improved aerodynamics.

This headset is compatible with standard tapered steerer tubes that transition from 1-1/8 inches at the top to 1.5 inches at the crown race. Please verify your fork's steerer dimensions before purchasing to ensure a proper fit.

No, 61mm is a specific measurement for the headset's outer diameter. You must confirm that your bicycle frame's head tube is designed to accept this specific size, as it is not a universal standard.

While it is technically possible, installing a headset requires a specialized headset press to ensure the cups are seated perfectly straight. If you are not comfortable with precision mechanical work, we recommend having a professional mechanic install it to avoid damaging your frame.

Yes, this FSA NO.55R headset includes the essential components required for installation, including the crown race, to ensure a seamless interface between your fork and the headset bearings.
