Why Titanium?

Stock hardware works — until it doesn’t.

Titanium is trusted across cycling because it offers an elite balance of:

• low weight

• high strength

• corrosion resistance

• long-term durability

S-Parts components are manufactured from TC4 Grade 5 titanium (Ti-6Al-4V) — an aerospace-grade alloy known for excellent fatigue resistance and strength-to-weight performance.

Many S-Parts titanium bolts and screws offer strength comparable to high tensile steel hardware, while weighing significantly less and staying corrosion-free year-round.

S-Parts Bolt & Screw Colour Options

S-Parts titanium hardware is available in 9 standout colourways:

• Blue

• Black

• Candy

• Gold

• Green

• Indigo

• Purple

• Rainbow

• Titanium

Perfect for matching frames, finishing kits, accent builds and custom upgrades.

How Are S-Parts Bolts & Screws Coloured?

S-Parts uses two proven finishing methods to achieve durable, high-end colourways:

Vacuum Nitriding

Used for:
Black, Blue, Gold, Rainbow

A hard-wearing surface treatment designed for durability and long-term appearance.

Anodising

Used for:
Candy, Green, Indigo, Purple

An electrochemical process that creates vivid colours while maintaining titanium’s natural corrosion resistance.

Measuring Your Bolts & Screws (Important)

Bolt sizing can be confusing — especially when brands measure hardware differently.

For S-Parts products, bolt and screw length refers to the shaft length only:
✅ measured from under the bolt head to the end of the thread.

S-Parts thread sizes range from M3 through to M10, covering the most common bicycle applications.

Installation Note

Always follow your component manufacturer’s official installation instructions and torque settings. If in doubt, use a torque wrench and reach out before fitting.

Weights may vary by ±2% due to manufacturing tolerances.
