Titanium Headset Crown Race is a lightweight 118 split crown component engineered for 1-1/8" split crown race for fork interface. Forged and CNC machined from Grade 5 Ti-6Al-4V, it achieves 40-45% weight savings versus steel while maintaining the fatigue life required for demanding cycling applications. Threaded interfaces are designed to prevent galling in outdoor environments.

Q: How much weight savings does Titanium Headset Crown Race offer versus steel or aluminum? ▼
Titanium Headset Crown Race fabricated from Grade 5 Ti-6Al-4V provides a 40-45% weight reduction versus 4130 chromoly steel (4.43 vs 7.85 g/cm³) at the same strength. Compared to 6061-T6 aluminum, titanium's 3× higher yield strength (830 vs 275 MPa) allows 50-60% thinner walls, resulting in a net weight comparable to aluminum with 4× better fatigue life — critical for 118 split crown.
Q: What is the typical lead time for Titanium Headset Crown Race orders? ▼
Standard lead time for Titanium Headset Crown Race is 15-25 business days depending on quantity and complexity. Rush orders (3-5 working days) are available for prototype evaluation. Sample evaluation (1-5 units) can be expedited to 5-7 business days. Volume pricing is available for production quantities above 100 units.
Q: What material certifications are provided with Titanium Headset Crown Race? ▼
Each Titanium Headset Crown Race shipment includes EN 10204 Type 3.1 mill test certificate with chemical analysis, mechanical properties, and heat identification. Dimensional inspection reports and Certificate of Conformance (CoC) are standard. First Article Inspection Reports (FAIR) per AS9102 are available on request for 118 split crown.
