Small upgrade. Massive difference.

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.
