CNC Bicycle Parts By Features
There are many different components in CNC machining bicycle parts. Due to different technical requirements, we can support you in material choice, surface finish recommendation and drawings support.

We have a tight control of concentricity and runout. Recommend hard anodize for wear resistance.

Providing clean and precise thread machining, we have in-house anodize production lines if needed.

Our surface roughness can be Ra1.6μm, accepting material selection for fatigue resistance.
Quality Control
Consistent quality reflects your brand value and ours. We ship over 500k CNC bicycle parts shipped worldwide annually.

We purchased the materials from the certified material supplier, who can provide a test report.

For the first sample that came out from the machine, we will do the first inspection with our CMM machine.

During CNC bicycle parts bulk production, we will test the parts every 2hours to avoid any mistakes.

After machining, all parts will be into full inspection, including the critical dimensions noted on the drawings.
Scratch-free surface for visible bike components
We provide a full-process, scratch-free surface for CNC bicycle parts, ensuring that every visible component maintains its perfect appearance.
From precise CNC machining to anodizing (which can match Pantone colors), beadblasting, or sandblasting treatment, each part is covered with a protective film and packaged individually to ensure zero scratches during transportation and assembly.
Professional-level surface control not only enhances the appearance but also safeguards the brand image and lifespan of high-end bicycles.

Fast DFM feedback for CNC Bicycle Parts
Our engineers provide rapid DFM (Design for Manufacturability) feedback for bicycle structural components, ensuring that your design reaches the optimal state before going into production.
Engineers will offer optimization suggestions regarding the feasibility of part processing, adjust tolerances to ensure smooth assembly, provide cost optimization solutions, and give material selection recommendations.
Through our professional guidance, your parts not only are easy to process, but also have stable performance and higher reliability.
