S-PARTS 3DAM Top Cap Compatible with Roval Rapide Cockpit

This S-PARTS 3DAM Integrated Headset Top Cap is designed to work with and visually complement the Roval Rapide Cockpit.

Produced using advanced metal additive manufacturing, this top cap combines precise structural design, low weight, and distinctive surface finishes across a wide range of colourways. Designed specifically for use on builds using the integrated Roval Rapide Cockpit, it delivers a refined finishing detail without compromising strength or reliability.

What is 3DAM Additive Manufacturing?

3DAM (Metal Additive Manufacturing) is a production process where metal components are built layer by layer from ultra-fine titanium powder using digital 3D design data. Unlike traditional subtractive manufacturing methods such as turning or milling, additive manufacturing does not remove material from a solid block. Instead, it constructs the part from nothing, stacking microscopic layers of metal powder to form the final three-dimensional structure.

At S-PARTS, metal additive manufacturing is not treated as a novelty, but as a mature and practical production method. After years of technological development, this process has become deeply integrated into modern mechanical manufacturing and is now widely used beyond high-end industrial applications, including performance-focused civilian products.

One of the key advantages of additive manufacturing is its ability to realise complex geometries that are difficult or impossible to produce using traditional methods. This includes complex curved surfaces, ultra-thin structures, and highly efficient material layouts. By combining professional 3D design with mechanical simulation, material distribution can be precisely controlled to achieve optimal strength while eliminating unnecessary weight.

During development, S-PARTS found that many small, highly stressed components do not benefit from common industry approaches such as large-area hollowing or topology optimisation. Hollow designs often require increased wall thickness to maintain strength, reducing overall weight savings, while support structures can add unnecessary mass.

Instead, S-PARTS uses precise mechanical structural design and professional simulation software to optimise wall thickness at different stress points. This approach maximises strength and weight efficiency without relying on hollow cavities or excessive support structures.

All S-PARTS 3DAM products are produced using BLT SLM (Selective Laser Melting) metal printers and high-purity TC4 (Grade 5) titanium powder. The powder particle size is strictly controlled between 15 and 53 microns and complies with international standards such as GB and ASTM.

During printing, layer thickness is precisely controlled at 20 microns per layer. Although this significantly increases print time compared to conventional settings, it results in a noticeably finer surface finish and more consistent structural quality.

After printing, each component undergoes stress-relief annealing to eliminate internal stresses and stabilise the metal structure. This is followed by support removal, manual finishing, and surface colouring or coating. These steps ensure consistent mechanical performance, refined surface quality, and long-term reliability.

S-PARTS views additive manufacturing as a complement to traditional manufacturing methods rather than a replacement, combining advanced production technology with practical engineering and craftsmanship.

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.

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.
