Grade 5 Titanium Performance

S-PARTS works closely with a professional metal material supply chain from Xi’an Civil Aerospace Industrial Base, continuously selecting and testing titanium materials that meet S-PARTS performance standards.

The Grade 5 Titanium (Ti-6Al-4V) alloy used in S-PARTS fasteners achieves an average tensile strength exceeding 1050 MPa, significantly higher than the industry benchmark of 895 MPa.

Under equivalent conditions, S-PARTS titanium fasteners deliver mechanical performance comparable to Class 10.9 steel hardware, while reducing weight by approximately 50% compared with conventional steel components.

With an exceptional strength-to-weight ratio, titanium provides lightweight performance and durability that traditional metals cannot match.

Precision Forged & CNC Machined

Every S-PARTS titanium bolt head is precision forged using custom-designed dies at 650°C.

To maintain consistent forming accuracy, each forging die is limited to fewer than 300 production cycles.

The fastener bodies are then machined in-house using military-grade multi-axis CNC equipment.

Through micron-level tolerance control, each thread is precisely manufactured for smooth engagement, accurate installation, and long-term reliability.

Premium Titanium Surface Finishes

Gold / Rainbow / Oil Slick / Black / Blue

These finishes are created using PVD vacuum nitriding technology, forming a dense titanium nitride surface layer that improves surface hardness, wear resistance, and impact durability.

The colors are integrated into the titanium surface rather than applied as paint, providing a premium metallic finish designed to withstand normal riding conditions.

Titanium / Green / Purple / Candy / Indigo

These finishes are achieved through titanium anodizing, creating a controlled oxide layer that improves surface durability and corrosion resistance.

No dyes or pigments are used.

During anodizing, the relationship between oxide layer thickness and light refraction creates unique interference colors, producing the naturally brilliant appearance of titanium.

Lightweight Titanium Upgrade for Giant Propel

The S-PARTS Titanium Saddle Clamp Bolt Kit combines Grade 5 Titanium strength, precision manufacturing, and lightweight design to provide a premium hardware upgrade for Giant Propel Gen 3 and Gen 4 riders.

With aerospace-grade material selection, precision machining, and distinctive titanium finishes, it delivers the ideal balance of performance, durability, and visual refinement for high-performance road bikes.
