Product Overview: Precision Engineering for Performance Framesets
Designed for builders who demand uncompromising quality, our EC34-EC34 / ZS34-ZS34 Titanium Headtube offers the perfect foundation for performance-oriented bicycle frames. Precision-machined from aerospace-grade Grade 5 titanium, this versatile component accommodates both external (EC34) and zero-stack (ZS34) headset systems, providing maximum design flexibility for custom frame builders and production manufacturers.
Aerospace-Grade Material: Grade 5 Titanium (Ti-6Al-4V)
Crafted from the industry-standard alloy for high-performance bicycle frames, our headtubes deliver:
- Exceptional Strength-to-Weight Ratio: Grade 5 titanium provides structural integrity while keeping overall frame weight minimal.
- Proven Durability: Ti-6Al-4V is trusted in aerospace and medical applications where reliability is non-negotiable.
- Natural Corrosion Resistance: Ensures your frames remain beautiful and functional for decades.
- Premium Aesthetic: The raw titanium finish can be polished, brushed, or left as-machined to match your brand identity.
Dual Compatibility: EC34 & ZS34 Headset Systems
This headtube is engineered to accommodate both popular headset standards, offering you and your customers greater flexibility:
- EC34-EC34 (External Cup): Traditional external headset cups for classic aesthetics and easy maintenance.
- ZS34-ZS34 (Zero-Stack): Modern integrated design for cleaner lines and lower stack heights.
- Universal Application: One headtube design covers multiple build specifications, simplifying your inventory.
Precision Dimensions for Perfect Fit
Every headtube is CNC-machined to exacting tolerances, ensuring seamless integration with standard 34mm headset systems.
