Elevate your custom framesets with our ZS44-ZS44 Hourglass Titanium Headtube—a component that seamlessly blends distinctive aesthetics with precision engineering. Machined from aerospace-grade Grade 5 titanium, this headtube features a sculpted hourglass profile that not only reduces weight but also adds an unmistakable visual signature to your builds. Designed for professional frame builders who demand both form and function.
Material Excellence: Aerospace-Grade Grade 5 Titanium
Crafted from Grade 5 (Ti-6Al-4V) titanium, the industry standard for high-performance bicycle frames, this headtube delivers:
- Exceptional Strength-to-Weight Ratio: The hourglass profile strategically removes material without compromising structural integrity.
- Aerospace Heritage: Grade 5 titanium is trusted in critical applications where failure is not an option.
- Natural Durability: Inherent corrosion resistance ensures your frames remain pristine for decades.
- Premium Finish: The raw titanium surface can be polished, brushed, or left as-machined to suit your brand aesthetic.
Engineering Precision for Integrated Headset Compatibility
Every dimension is held to strict tolerances to ensure seamless integration with ZS44-ZS44 (Zero-Stack 44mm) headsets. The headtube is specifically designed for:
- ZS44 Top and Bottom Cups: Perfect fit for standard integrated headset systems.
- Post-Weld Machining Allowances: Built-in material allowance for facing and reaming after welding, ensuring perfect cup seating and head alignment.
- Clean Aesthetics: The hourglass transition creates smooth lines that complement modern frame geometries.
