Specialized Tarmac SL8 Compatible (S-Works 12R + 10R)

This is the finishing kit upgrade your SL8 deserves.

If you’re building a Tarmac SL8 and you want the back end to look cleaner, sharper, and unmistakably custom — this is the move. The S-Parts 3DAM clamp assembly replaces the stock hardware with a precision-built titanium setup that looks like it belongs on a pro bike… but better.

No gimmicks. No “titanium for the sake of it.”
Just a properly engineered part that adds detail where it matters.

Built Off The Front

This clamp isn’t machined like normal parts. It’s metal 3D printed using SLM (Selective Laser Melting), built layer-by-layer from high-purity titanium powder.

That means:

• material only goes where it needs to

• strength stays consistent through the whole structure

• shapes are optimised, not limited by cutting tools

The result is a clamp assembly that’s strong, lightweight, and quietly unreal in the hand.

Designed With Intent

Every surface is shaped through simulation — refining strength and weight into a form that’s clean, modern, and purpose-built.

This is the kind of part that doesn’t shout.
It just makes the whole build look like it’s been thought through properly.

Material That Matters

Made from aerospace-grade TC4 titanium (Ti-6Al-4V) for:

• long-term fatigue resistance

• stability over time

• corrosion resistance

• that raw titanium finish that never gets old

Then heat treated to deliver real-world durability across seasons, mileage, and hard riding.

Compatibility

✅ Specialized Tarmac SL8
✅ Compatible with S-Works 12R and Standard 10R frames

Technical Specs

• Load-optimised structure design (FEA tuned wall thickness by stress point)

• SLM Titanium Additive Manufacturing (BLT laser powder bed fusion systems)

• High-purity TC4 Titanium (Ti-6Al-4V powder, GB + ASTM compliant)

• Powder particle size: 15–53 μm (density + fusion control)

• Post-process annealed for strength + fatigue resistance

• Tensile strength up to 1030 MPa

• Yield strength up to 980 MPa

• Excellent ductility + toughness

Off The Front verdict

If you’re already building an SL8 properly, this is one of those upgrades that takes it from high-end to hyper-dialled.

Clean. Technical. Unmistakable.

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.

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.

If you’re unsure what size you need, contact us — we’ll help you match the correct part.

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.
