Product Description

S-PARTS 3DAM Titanium Seatpost Kit

Dual Titanium Structure | 3D-Printed Clamp | Lightweight Comfort Performance

The S-PARTS 3DAM Titanium Seatpost Kit combines advanced titanium materials with optimized structural design to deliver a perfect balance of strength, comfort, durability, and lightweight performance.

Unlike traditional titanium seatposts, the 3DAM system features a dual-material construction:

• The saddle clamp structure is manufactured from 3D-printed Grade 5 Titanium (Ti-6Al-4V) for high strength and precise load distribution.
• The seatpost tube is made from Grade 9 Titanium (Ti-3Al-2.5V), a titanium alloy widely used in high-performance bicycle frames for its excellent fatigue resistance and vibration damping characteristics.

By combining two titanium technologies into one integrated design, the S-PARTS 3DAM Seatpost delivers reliable support for demanding rides while maintaining the natural comfort advantages of titanium.

Dual Titanium Construction

Grade 5 Titanium 3D-Printed Saddle Clamp + Grade 9 Titanium Tube

The core innovation of the S-PARTS 3DAM Seatpost lies in its dual titanium structure.

The upper saddle support system is produced using 3D-printed Grade 5 Titanium (Ti-6Al-4V). Through additive manufacturing, the clamp structure can achieve optimized geometry, improved load distribution, and excellent structural strength.

The main seatpost tube uses Grade 9 Titanium (Ti-3Al-2.5V), a premium titanium alloy commonly used in lightweight bicycle frames.

Grade 9 titanium provides an ideal balance of:

• High fatigue resistance
• Controlled stiffness
• Natural vibration absorption
• Long-distance riding comfort

The combination of these two titanium materials creates a seatpost system that delivers both responsive power transfer and titanium’s signature smooth ride quality.

Optimized Structural Performance

Compared with the previous generation design, the updated 3DAM structure achieves:

• Approximately 30% improvement in overall structural strength
• Approximately 11% reduction in component weight

Every load-bearing area has been carefully optimized to improve stability, durability, and riding performance.

Advanced 3DAM Saddle Rail Clamp System

The upgraded 3DAM saddle clamp system is designed to provide stronger holding force and more consistent pressure distribution.

Compared with traditional saddle clamp structures:

• Approximately 20% higher structural strength
• Approximately 25% lower clamp system weight
• Improved saddle stability
• More direct power transmission during acceleration

The optimized clamp design increases saddle rail contact area by approximately 40%, allowing the clamping force to be distributed more evenly.

Compatible with:

• Carbon saddle rails
• Titanium saddle rails
• Alloy saddle rails

Compatibility

Available diameter options:

• 31.8mm x 580mm
• 33.9mm x 580mm
• 34.9mm x 580mm

Please confirm your bicycle frame seat tube diameter before ordering.

Precision Titanium Manufacturing

3D printing is not simply a styling choice — it is an advanced manufacturing method that allows engineers to create complex structures with optimized strength-to-weight ratios.

After the printing process, each titanium component undergoes:

• Stress-relief heat treatment
• Support removal
• Precision finishing
• Surface preparation
• Titanium color treatment

S-PARTS combines additive manufacturing technology with traditional precision machining methods to create high-performance bicycle components that balance engineering performance and artistic design.

Limited Stained-Glass Titanium Finish

Inspired by the luminous stained-glass windows of medieval cathedrals, the S-PARTS Stained-Glass finish is a limited-edition titanium surface treatment that transforms the metal surface into a unique interaction of color and light.

The combination of titanium craftsmanship and advanced surface treatment creates a distinctive appearance where industrial engineering meets artistic expression.

Available finishes:

• Gold
• Rainbow
• Black
• Blue
• Stained-Glass (Limited Edition)
