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

Product Description Not Designed. Grown. This is not a conventional headset top cap. Developed by TiNE × Eclos, it applies BESO topology optimization to create a structure that evolves along real force paths — removing excess material while preserving strength. The result is a form that feels less engineered, and more… grown. 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 What remains is a pure load-bearing structure — efficient, minimal, and visually striking. Ultralight Performance Two dedicated versions for precise Pinarello fitment: Pinarello 2021 Version — approx. 7.5g Pinarello 2025 Version — approx. 8.2g Every gram is engineered — not compromised. 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 Lightweight, without sacrificing reliability. 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 Your cockpit, refined.
