This Titanium Fork Compression Assembly is specifically engineered for the Colnago Y1RS integrated fork and headset system, providing secure headset preload and stable front-end assembly.

Manufactured from S-PartS SJ-Grade TC4 Titanium Alloy (Ti-6Al-4V) using precision CNC machining, the components deliver an exceptional strength-to-weight ratio while maintaining long-term durability.

Through internal laboratory comparison testing, the material demonstrates an average tensile strength exceeding 1050 MPa, significantly higher than the typical industry requirement of ≥895 MPa.

Under comparable conditions, TC4 titanium fasteners offer mechanical performance similar to Grade 10.9 steel components, while weighing approximately half as much, making them an ideal solution for high-performance lightweight road bike builds.

This system is designed specifically for the Colnago Y1RS platform, with XS / S / M / L Size options to ensure precise compatibility across different frame Sizes.

Riders may purchase the complete compression assembly or individual replacement components depending on their needs.
