S-PARTS TC4 Titanium Bolt Kit for Colnago Y1RS | Frame & Cockpit Screw Upgrade
S-PARTS TC4 Titanium Bolt Kit for Colnago Y1RS
Upgrade the details of your Colnago Y1RS with the S-PARTS TC4 Titanium Bolt Kit, developed specifically for the corresponding frame and cockpit mounting points.
Rather than simply replacing the original hardware with lighter bolts, S-PARTS combines S-Grade TC4 titanium alloy, precision machining and multiple surface finishes to create a functional and visual upgrade for the Y1RS.
Each mounting position is matched with the appropriate bolt head style and dimensions to provide a clean, integrated appearance while reducing unnecessary hardware weight.

DEVELOPED FOR THE COLNAGO Y1RS
This kit is developed around the specific mounting requirements of the Colnago Y1RS.
Different locations on the bike require different bolt geometries. S-PARTS uses multiple bolt styles and head profiles rather than relying on a single universal bolt design.
This allows the hardware to better match the intended contact surfaces and mounting positions of the Y1RS while maintaining a clean OEM-style fit.
S-GRADE TC4 TITANIUM
S-PARTS selects S-Grade TC4 titanium alloy for this upgrade kit, combining low weight with excellent mechanical strength.
According to the supplied material specifications, the selected TC4 titanium material has an average tensile strength exceeding 1050 MPa, comparable to high-strength 10.9-grade steel components while offering substantially lower material weight.
The result is an excellent balance of:
Low Weight · High Strength · Corrosion Resistance · Premium Finish
LIGHTWEIGHT WITHOUT COMPROMISING STRENGTH
Titanium is valued in high-performance cycling because of its excellent strength-to-weight ratio.
Replacing selected steel hardware with TC4 titanium components can reduce weight while retaining the strength required for their intended mounting positions.
For riders building a premium Y1RS, it provides a detail-oriented upgrade where performance, material quality and aesthetics come together.
PRECISION-MATCHED BOLT DESIGNS
Not every mounting point on the Y1RS uses the same bolt design.
S-PARTS uses different head profiles and specifications, including countersunk, socket-head and other application-specific designs, to match the requirements of individual mounting locations.
The different contact surfaces are designed to provide stable torque application and a cleaner finished appearance after installation.
PRECISION MANUFACTURING
The titanium hardware is produced using dedicated tooling and controlled manufacturing processes.
According to the supplied manufacturing information, the production process includes high-temperature forming at approximately 650°C, followed by precision machining and dimensional inspection.
Each tooling set undergoes repeated fit and dimensional testing to maintain consistent thread engagement and component tolerances.
Precision machining helps ensure:
- Consistent thread dimensions
- Accurate bolt geometry
- Clean head profiles
- Reliable fitment
- Refined surface details
PREMIUM COLOR FINISHES
The S-PARTS Y1RS Titanium Bolt Kit is available in a wide selection of finishes, allowing the hardware to complement both understated and highly customized bike builds.
Depending on the selected color, S-PARTS uses PVD vacuum coating and anodizing processes to create the final finish.
Available Colors:
Gold / Rainbow / Titanium / Black / Blue / Green / Purple / Candy / Indigo / Walnut
Due to the nature of anodizing and PVD finishing, exact color tone and gradient distribution may vary slightly between individual titanium components.
DESIGNED AS A VISUAL UPGRADE
Small hardware details can have a significant effect on the overall appearance of a premium bike build.
The S-PARTS titanium kit is designed to replace the understated appearance of selected factory hardware with precision-machined titanium components that complement the design of the Colnago Y1RS.
Choose Titanium or Black for a subtle OEM-inspired appearance, or use Gold, Rainbow, Blue, Purple, Candy and other finishes to create a more personalized build.
