1 / 5
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.
Actually we provide OEM/ODM services for many famous international brands in Europe and America. For example, TOTO, Dornbracht, Roca, KLUDI.
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.
They are made from premium ZAMAK 5 / ZA-8 zinc alloy (Grade AZ-81A). This high-grade material ensures excellent tensile strength, outstanding durability, and long-term performance under stress.
Yes, we provide extensive OEM/ODM customization services. You can customize the clamp diameter, stem length, angle, and hole patterns. Our engineering team can adapt designs to your specific mechanical and aesthetic requirements.
We offer Polished, Chrome Plating, Powder Coating, Painting, and PVD coatings (such as Gold, Black, and Gunmetal). Our standard plating (Cu ≥ 15um, Ni ≥ 10um, Cr ≥ 0.15um) passes a neutral 240-hour or acidic 48-hour salt spray test. Custom finishes can also be tailored to exceed 480 hours of neutral salt spray testing.
For custom designs, the sample lead time is typically 7 to 35 days. Once the sample is confirmed, mass production generally takes 25 to 45 days.
They are widely applied in Bicycles, E-bikes, Mountain Bikes, Electric Scooters, Motorcycles, Fitness Equipment, Exercise Machines, Agricultural Machinery, Carts, and Industrial Equipment/Control Levers.
No. We promise never to use return or recycled materials directly for die-casting production. This guarantees high structural integrity and consistent product quality for all custom parts.
