Premium Surface Finishes

PVD Vacuum Nitriding Finish

Available in Gold, Rainbow, Black and Blue

Gold, Rainbow, Black and Blue finishes are treated using an advanced PVD (Physical Vapor Deposition) vacuum nitriding process.

This technology forms a dense metallic nitride layer on the titanium surface, improving:

• Surface hardness
• Wear resistance
• Impact resistance
• Corrosion resistance

Unlike painted coatings, the finish is integrated into the surface and maintains its rich metallic appearance through rain, mud, frequent washing and everyday riding.

recision Anodized Finish

Available in Green, Purple, Candy and Indigo

These colors are created through an electrochemical anodizing process rather than paint or dyes.

By precisely controlling the thickness of the oxide layer, light is refracted at different wavelengths to produce vibrant metallic colors while simultaneously improving corrosion resistance and surface durability.

The result is a distinctive finish that showcases the natural beauty of titanium.

Aerospace-Grade Grade 5 Titanium

Performance starts with premium materials.

S-PARTS works closely with aerospace material suppliers in Xi'an to source carefully selected Grade 5 Titanium (Ti-6Al-4V) that meets our strict internal quality standards.

Why Choose Grade 5 Titanium?

✔ Ultra-High Strength

Average tensile strength exceeds 1050 MPa, significantly higher than the industry standard of 895 MPa.

✔ Approximately 50% Lighter Than Steel

Delivers mechanical performance comparable to Class 10.9 steel fasteners while reducing overall weight by nearly half.

✔ Excellent Corrosion Resistance

Titanium naturally resists rust and oxidation, making it ideal for wet, muddy and demanding riding environments.

✔ Outstanding Strength-to-Weight Ratio

Engineered for riders seeking maximum performance without unnecessary weight.

Precision CNC Manufacturing

Every S-PARTS titanium fastener is manufactured with meticulous attention to detail.

The bolt head is hot forged using exclusive S-PARTS tooling before the entire fastener is precision CNC machined to micron-level tolerances.

This process ensures:

• Precise thread engagement
• Smooth installation
• Reliable cable clamping performance
• Consistent fit and finish
• Long-term durability

Every bolt is carefully inspected before leaving the factory to ensure it meets S-PARTS quality standards.

Why Upgrade to Titanium?

Compared with conventional steel hardware, titanium offers significant advantages:

• Lightweight performance upgrade
• High mechanical strength
• Outstanding corrosion resistance
• Will not rust
• Excellent fatigue resistance
• Premium appearance for custom bike builds

Small details can make a noticeable difference to both performance and aesthetics.

Package Includes

• 1 × S-PARTS Grade 5 Titanium M6×10 Rear Derailleur Cable Pinch Bolt

Installation Tips

• Apply a thin layer of anti-seize compound to the threads before installation.
• Start threading by hand to avoid cross-threading.
• Tighten according to Shimano's recommended torque specification.
• Do not overtighten titanium fasteners.
