TiNE × Eclos BESO Titanium Headset Top Cap for Pinarello 2021 / 2025

TiNE × Eclos titanium headset top cap for Pinarello 2021 and 2025 cockpit versions. BESO topology optimization produces an open skeletal structure, with dedicated fitments weighing approximately 7.5g and 8.2g respectively.

The design uses Bidirectional Evolutionary Structural Optimization (BESO) to remove unnecessary material while retaining the intended load-bearing geometry.

Select the correct 2021 or 2025 version; these are model-specific fitments.

BESO Topology Optimization

Instead of machining a solid shape, the structure is generated through:

• Bidirectional Evolutionary Structural Optimization (BESO)
• Material distributed only where stress exists
• Removal of all non-essential mass

The result is an open, load-focused structure with a distinctive appearance.

Ultralight Performance

Two dedicated versions for precise Pinarello fitment:

• Pinarello 2021 Version — approx. 7.5g
• Pinarello 2025 Version — approx. 8.2g

The two variants have distinct weights and cockpit interfaces.

CryoFusion αβ-64 Titanium

Built from advanced TC4 titanium (Ti-6Al-4V) with optimized microstructure:

• High tensile strength
• Excellent fatigue resistance
• Long-term durability under real riding conditions

The TC4 alloy is selected for strength and durability in cycling use.

Precision Fit for Pinarello

• Designed specifically for Pinarello 2021 & 2025 platforms
• Accurate interface with headset system
• Clean and seamless cockpit integration

Form Meets Function

This is where engineering becomes visual identity:

• Organic skeletal geometry
• Distinctive front-end detail
• A subtle but powerful upgrade

Choose the version that matches your Pinarello cockpit.
