S-Parts Titanium Brake Bolt Kit – Shimano Dura-Ace & Ultegra

Complete Titanium Brake Hardware Upgrade for Shimano Dura-Ace R9250 / R9270 & Ultegra R8150 / R8170

The S-Parts Titanium Brake Bolt Kit is a complete lightweight hardware upgrade for compatible Shimano Dura-Ace and Ultegra 12-speed road disc brake systems, replacing standard hardware throughout the brake calipers and shift/brake levers with precision-machined titanium components.

Designed for Shimano Dura-Ace R9250 / R9270 and Ultegra R8150 / R8170, this comprehensive 18-piece kit goes far beyond simply replacing the visible caliper mounting bolts. It covers hardware across the hydraulic connections, bleed system, brake pad retention, caliper assemblies and shift/brake levers.

Manufactured from S-Parts TC4 Grade 5 titanium (Ti-6Al-4V), the complete kit weighs approximately 28.7g, combining low weight with excellent strength, fatigue resistance and corrosion resistance.

For riders chasing grams, creating a custom colour scheme or refining an already high-end Shimano build, this is exactly the type of upgrade S-Parts does best — taking the components most people overlook and refining them right down to the smallest detail.

Complete kit weight – approximately 28.7g

The Details Make the Build

Once the major components of a performance build have been chosen, the remaining gains are found in the details.

The S-Parts Titanium Brake Bolt Kit takes that philosophy across the complete Shimano braking system — replacing 18 individual pieces of standard hardware with precision-machined TC4 titanium.

Individually, each component is a small upgrade. Across the entire braking system, they become part of a much bigger approach to building a lighter, more considered and completely individual bike.

Small components. 18 titanium upgrades. One properly finished build.

Why Choose S-Parts Titanium Bolts & Screws?

Small upgrade. Massive difference.

S-Parts are one of the most respected names in titanium bicycle bolts and screws, producing lightweight bike hardware designed for riders who care about performance and finishing detail. Since 2010, they’ve specialised in precision fixings for road, gravel, mountain and performance builds — helping riders reduce weight, prevent corrosion, and finish a bike properly.

Whether you’re chasing grams or building a clean custom colourway, S-Parts is one of the easiest ways to upgrade the details that most bikes leave behind.

With 1000+ bolt and screw options, S-Parts covers everything from cockpit hardware and bottle cages to drivetrain, brake and suspension fixings.

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.
