Product Specifications

Kit Includes

1 × Titanium Crank Bolt
1 × Titanium Self-Extracting Cap

Designed as a dedicated titanium hardware upgrade for CENIT DUB Axle Series systems.

Premium Ti-6Al-4V Titanium Material

S-PARTS carefully selects premium Ti-6Al-4V Titanium (Grade 5 Titanium) materials through continuous laboratory testing and strict quality control.

With an average tensile strength exceeding 1050 MPa, the material performance is significantly higher than the common industrial requirement of ≥895 MPa.

Compared with conventional steel hardware, titanium components offer:

• Approximately half the weight of steel equivalents
• Exceptional strength-to-weight ratio
• Excellent corrosion resistance
• Superior fatigue performance

Lightweight construction without compromising reliability.

Forged Strength Meets Precision Manufacturing

The self-extracting cap is manufactured using S-PARTS customized hot forging molds at approximately 650°C, creating a dense and strong metal structure while maintaining precise dimensional accuracy.

To maintain consistent forging quality, each production mold is strictly controlled and used for no more than 300 forming cycles before replacement.

The crank bolt and precision components are CNC machined using advanced manufacturing equipment with micron-level tolerance control.

This manufacturing philosophy ensures:

• Accurate thread engagement
• Reliable torque transmission
• Consistent installation precision
• Long-term structural durability

Every detail is engineered for riders who demand both performance and craftsmanship.

Premium Titanium Surface Finishes

S-PARTS combines advanced surface treatment technologies with titanium craftsmanship to create unique finishes.

PVD Vacuum Coating Finish

Gold, Black, Oil Slick (Rainbow), and Indigo finishes are produced using PVD vacuum coating technology.

A dense protective coating layer is formed on the titanium surface, improving:

• Surface hardness
• Wear resistance
• Scratch resistance
• Long-term color durability

The finish provides a premium appearance while maintaining excellent protection against everyday riding conditions.

Titanium Anodized Finish

Titanium, Green, Purple, and Candy colors are created through electrochemical anodizing technology.

Without using dyes, the natural oxide layer on titanium creates different colors through light interference effects.

This process provides:

• Unique titanium colors
• Natural surface protection
• Improved corrosion resistance
• A distinctive custom appearance

Each color represents the natural beauty of titanium material itself.
