• High strength-to-weight ratio
• Approximately 50% weight reduction compared with steel parts
• Excellent corrosion resistance
• Long-term durability in demanding riding environments

Designed for riders who value lightweight performance and premium mechanical details.

Precision CNC Machined for Accurate Adjustment

Each S-PARTS titanium limit screw is manufactured using precision CNC machining technology with strict dimensional control.

The refined machining process ensures:

✓ Accurate thread engagement
✓ Smooth adjustment operation
✓ Reliable installation fit
✓ Consistent manufacturing quality

A small component with critical influence on drivetrain adjustment precision.

Premium Titanium Color Finishes

PVD Vacuum Nitriding Coating

Gold / Black / Blue / Rainbow

Selected colors are treated with advanced PVD vacuum nitriding coating technology, creating a durable metallic surface layer.

Advantages:

• Increased surface hardness
• Improved wear resistance
• Enhanced surface protection
• Long-lasting color performance

Titanium Electrochemical Anodized Finish

Green / Purple / Candy / Indigo

Through controlled electrochemical anodizing, the titanium surface forms a natural oxide layer.

The unique colors are created by the interaction between oxide layer thickness and light interference, without using artificial dyes.

Features:

• Natural titanium color effect
• Excellent corrosion resistance
• Unique metallic appearance
• Premium customization options
