Product Description

Precision-Engineered for the Colnago V5Rs & Y1Rs

The S-PARTS 3D Printed Titanium Lower Saddle Cradle is a direct replacement for the lower cradle used in the saddle clamp assembly of Colnago V5Rs and Colnago Y1Rs seatposts.

Designed specifically for riders pursuing the ultimate balance of lightweight performance, structural efficiency, and premium craftsmanship, this component replaces the original aluminum lower cradle with an advanced SLM 3D-printed Grade 5 titanium construction.

Weighing just 7.5 g per piece, it offers a substantial reduction in weight while maintaining the structural integrity required for demanding road riding.

FEA-Optimized Lightweight Structure

Conventional machined or cast components often retain excess material due to manufacturing limitations.

Instead of following traditional design methods, S-PARTS engineers each Lower Saddle Cradle using Finite Element Analysis (FEA) to evaluate real-world load paths throughout the component.

Material is strategically concentrated in high-stress areas while low-load sections are refined into an ultra-thin shell structure, producing an optimized balance between strength, stiffness, and weight.

Rather than simply removing material, every gram is engineered with purpose.

Industrial SLM Metal Additive Manufacturing

Each Lower Saddle Cradle is manufactured using Selective Laser Melting (SLM), one of the most advanced metal additive manufacturing technologies available.

Produced on industrial-grade BLT metal 3D printing systems, every component is built from high-purity Grade 5 Titanium (Ti-6Al-4V) powder using an ultra-fine 20 μm layer thickness for exceptional dimensional accuracy and surface quality.

The manufacturing process includes:

• SLM laser powder bed fusion
• Stress-relief heat treatment
• Precision support removal
• Hand surface finishing
• Thread machining
• Premium titanium surface finishing

This multi-stage production process ensures outstanding consistency, durability, and precision.
