Material & Mechanical Performance

Machined from Ti-6Al-4V titanium (Grade 5), this fastener kit delivers an excellent balance of strength, durability, and weight reduction.

Measured average tensile strength reaches ~1050 MPa, exceeding the typical industry reference value of ~895 MPa for standard Grade 5 titanium.

Under identical conditions, its mechanical performance is comparable to 10.9-grade steel fasteners, while reducing weight by approximately 50%.

Ti-6Al-4V titanium is widely used in high-performance cycling, motorsport, and aerospace applications, where fatigue resistance and mass reduction are critical.

Surface Finish Options

PVD Vacuum Coating (Gloss Finish)
Gold / Blue / Black / Rainbow
A hard, wear-resistant nitride coating with color bonded to the metal surface for long-term durability.

Anodized Finish (Matte Appearance)
Green / Purple / Candy/ Indigo
Formed through controlled electrochemical oxidation for stable color and a distinctive matte look.

Precision Machining & Fitment

CNC-machined for accurate engagement with a 4 mm hex (Allen) key, ensuring reliable torque transfer and reduced risk of tool slip or rounded heads during installation.

Installed Appearance

When installed, titanium hardware not only reduces weight but also provides a clean, performance-oriented visual upgrade, especially when paired with color-matched builds.

💡 Why Titanium?

Compared to stainless or stock steel, titanium is the smart upgrade for riders who care about long-term durability, corrosion resistance, and reducing weight without sacrificing strength.
