Premium Grade 5 Titanium Construction

Strength, Lightweight Design, and Precision

S-PARTS carefully selects Grade 5 Titanium (Ti-6Al-4V) through a professional titanium material supply chain and continuous laboratory verification.

Each batch is tested according to strict S-PARTS standards, achieving an average tensile strength exceeding:

1050 MPa

Compared with conventional steel hardware, S-PARTS titanium components provide:

  • Excellent strength-to-weight ratio
  • Approximately 50% weight reduction compared with steel parts
  • Mechanical performance comparable to 10.9 grade steel components

Precision Forged and CNC Machined

Engineered for Reliable Fit and Finish

Each S-PARTS titanium headset top cap is manufactured through precision forging and CNC machining processes.

Dedicated forging molds are carefully controlled to maintain consistent production accuracy, with each mold used for no more than 300 forming cycles.

Precision CNC machining ensures:

  • Accurate dimensions
  • Smooth surface finish
  • Secure bolt engagement
  • Reliable installation performance

Premium Vacuum Nitriding Finish

Long-Lasting Color with Titanium Character

Gold, Rainbow, Black, and Blue finishes are created using S-PARTS proprietary vacuum nitriding coloring process.

  • Rain
  • Mud

Helping your bike maintain its unique appearance ride after ride.
