Product Description

S-PARTS 3DAM Titanium Thru Axle Kit for Specialized Tarmac SL8 / SL9

A new generation of lightweight performance components created through advanced metal additive manufacturing technology.

The S-PARTS 3DAM Titanium Thru Axle Kit is specially designed for Specialized Tarmac SL8 and SL9 road bikes, combining aerospace-grade TC4 titanium alloy with optimized internal structures to achieve an exceptional balance between weight reduction, strength, and durability.

Using professional SLM (Selective Laser Melting) 3D printing technology and simulation-based structural optimization, S-PARTS engineers analyze stress distribution and precisely optimize material placement.

The result is an ultra-lightweight thru axle system with excellent mechanical performance, designed for riders who demand maximum performance from every detail.

Advanced 3D Printed Titanium Technology

Unlike traditional CNC machining, metal additive manufacturing allows complex internal structures that cannot be achieved through conventional processes.

Through professional simulation analysis:

• Stress areas are precisely calculated
• Material distribution is optimized
• Unnecessary weight is removed
• Structural strength is maintained

This advanced design creates a lightweight yet highly reliable thru axle.

Aerospace-Grade TC4 Titanium Alloy

Made from premium TC4 titanium alloy powder used in aerospace applications.

Material advantages:

• High strength-to-weight ratio
• Excellent corrosion resistance
• Superior fatigue resistance
• Lightweight construction
• Long service life

The performance is comparable to high-grade steel components while significantly reducing weight.

Ultra-Lightweight Performance Upgrade

Weight optimization is critical for high-performance road bikes.

The 3DAM titanium structure provides:

• Reduced unnecessary weight
• Excellent stiffness and strength
• Premium lightweight upgrade
• Ideal for racing and custom builds

Perfect for riders building a lightweight Specialized Tarmac SL8 / SL9.
