Made from high-grade ZAMAK 5 (ZA-8) alloy, ensuring excellent tensile strength, durability, and long-term performance under stress.
Manufactured using advanced die-cast molding technology for complex, consistent geometries with tight tolerances and a smooth, clean surface finish, ready for further processing.
Tailor the stem to your exact needs. Customize the clamp diameter, length, angle, and hole patterns. We can adapt the design to your specific mechanical and aesthetic requirements.
Available in a variety of finishes including Polished, Chrome Plating, Powder Coating, PVD (Physical Vapor Deposition) coatings like Gold, Black, Gunmetal, and more. All finishes are designed to pass rigorous salt spray tests (e.g., 96+ hours).
The zinc alloy base combined with high-quality plating/coating provides outstanding resistance to rust, tarnish, and wear, making it suitable for indoor and outdoor use.
Designed for straightforward assembly, often featuring precisely machined clamping surfaces and clean bolt hole threads for a secure and reliable fit.

Ready to customize your handlebar stems? Send us your technical drawings, 3D files, or samples. Our engineering team will review your needs and provide a competitive solution.
With the whole process of moulding, die-casting, machining, polishing, plating/powder coating/painting, inspection, assembly and shipment, we can strictly control every step of handle production to ensure quality and improve product qualification rate.
We strictly control the thickness of plating layer of copper, nickel and chrome, usually our plating thickness is: Cu ≥ 15um, Ni ≥ 10um, Cr ≥ 0.15um, and can pass neutral 240 hours or acidic 48 hours salt spray test. We also customize your handles for salt spray testing in excess of neutral 480 hours. And we promise never to use the return material directly for die-casting production.
Our handlebar stems are made from premium ZAMAK 5 / ZA-8 Zinc Alloy (Grade AZ-81A) using a high-pressure die-casting production process.
Yes, we provide full OEM/ODM customization services. You can customize the clamp diameter, length, angle, hole patterns, and overall design to meet your specific mechanical and aesthetic requirements.
We offer standard finishes including Polished, Chrome Plating, PVD Coating, Powder Coating, and Paint. Color options include Silver, Black, Gold, Gunmetal, and custom RAL colors.
For custom designs, the sample lead time is 7-35 days. Mass production typically takes 25-45 days after the sample is confirmed.
We strictly control the plating thickness (Cu ≥ 15um, Ni ≥ 10um, Cr ≥ 0.15um). Our products can pass a neutral 240 hours or acidic 48 hours salt spray test, and we can customize handles to exceed neutral 480 hours of salt spray testing.
No, we guarantee that we never use return or recycled material directly for die-casting production, ensuring the highest material integrity and product strength.
