• Fatigue-resistant joints for long-lasting performance
• Popular for handcrafted premium frames

Duplex Stainless Steel:

• Up to twice the yield strength of standard stainless steel
• Superior fatigue and load-bearing capabilities
• Ideal for high-performance and e-bike frames

Titanium-Ready Fabrication:

• Minimal distortion for lightweight structures
• Precision welding for racing and custom frames
• Optimized for structural integrity and reduced weight

Manufacturing Highlights:

• 20+ certified welders with long-term professional experience
• Multi-material welding capability (carbon steel, stainless, duplex, titanium)
• CNC tube bending and forming for complex geometries
• Prototyping to high-volume production
• Full material traceability

These capabilities help reduce production risk and ensure consistent, high-quality bike frame head tube components for OEMs and custom builders.

Applications of Bike Frame Head Tubes:

• Custom Road, Gravel, and Touring Bikes: Accurate steering geometry and durable joints

FAQ:

Q: What is the minimum order quantity (MOQ)?
A: We accommodate both prototype and production runs. MOQ starts at 10–50 units depending on design complexity and material.

Q: How long is the lead time?
A: Prototype: 2–4 weeks. Mass production: 4–8 weeks depending on volume and finishing requirements.

Q: Can you manufacture according to our drawings?
A: Yes. We produce bike frame head tube components from 2D drawings, 3D CAD files, or physical samples.

Q: Do you support small-batch production?
A: Absolutely. Our flexible setup supports low-volume pilot runs as well as high-volume production.

Q: What welding methods are used?
A: TIG for thin-wall, low-distortion assemblies; MIG for higher-volume production with consistent results.

Q: How is shipping handled?
A: EXW, FOB, CIF, DDP, via courier, air, or sea freight—flexible to meet your requirements.

Q: Can you provide full fabrication services?
A: Yes. Beyond welding, we offer CNC tube bending, end forming, machining, surface finishing, and assembly, delivering a complete solution for bike frame head tube projects.
