From raw materials to final shipment, we carry out 12 rigorous quality inspection processes for all parts. CMM measurement, in-process checks, and a dedicated quality team verify critical dimensions, installation references, and functional features.
The production of our parts follows strict international quality standards. Our facility is ISO 9001:2015 and IATF 16949 certified, with annual SGS verification to ensure consistent manufacturing and traceable quality.
Bicycle chain guides are machined precisely to your design drawings. Customers can define dimensions, shape, mounting style, and surface finish, and we can also include custom logos or engraving as required.
Custom CNC bicycle chain catcher can be finished with a variety of surface treatments, including anodizing, sandblasting, powder coating, and painting, to meet both functional and aesthetic requirements.
If required, we provide professional assembly for bike chain catcher. Services include fitting parts together, verifying chain clearance and alignment, functional checks, and pre-shipment inspection to ensure meets specifications.
Common materials for bike chain catcher production include aluminum alloys, carbon steel, and stainless steel. Aluminum is lightweight, strong, and easy to CNC machine. Carbon steel provides high strength and wear resistance for demanding conditions. Stainless steel offers corrosion resistance and long-term durability.
Key Considerations for Material Choice
| MATERIAL | GRADE / STANDARD |
|---|---|
| Aluminum Alloy | 6061-T6, 6082-T6 |
| Carbon Steel | AISI 1045 (SAE) |
| Stainless Steel | AISI 304, AISI 316 |
Before machining your bicycle chain guides, our surface treatment engineers select the most suitable and cost-effective finishing method based on your requirements. We have provided surface finishing services for thousands of metal and plastic components. Common surface treatments for chain guides include:
| Aluminum Parts | Anodizing, sandblasting anodizing, oil spraying, electroplating, wire drawing, polishing, etc. |
| Stainless Steel | PVD (vacuum coating), electroplating, passivation, etc. |
| Steel | Galvanized, black oxide, powder coating, etc. |
| Copper | Passivation, electroplating |
| Plastic | Painting, brushing (acrylic), printing, thermal transfer, etc. |

We have an independent department to track the progress of orders and maintain detailed records of each production batch. The machining photos and videos will be transparently shared with customers at any time to let customers know the progress of product machining at any time.
Dimensional tolerance inspections are conducted every two hours,, with first-article and IPQC inspections to ensure stable processes and consistent quality.
Conduct statistical analysis to monitor and control the manufacturing process and provide inspection reports.
If any deviations, defects or non-conformities are discovered while machining a part, our team will immediately convene a meeting to resolve the issue.
We respond to abnormal situations within 30 minutes, provide solutions within 2 hours, and ensure that the problems are resolved within 24 hours.
Before CNC parts leave the factory, 100% dimensional inspection is conducted according to customer drawings. Inspection reports are provided before proceeding to the next processing step.
We offer anodizing, sandblasting, powder coating, etc., we also provide special surface treatments. All surface treated parts are subject to 100% visual inspection after returning to the workshop.
QC specialists inspect parts at each stage using tools like 3D/2D projectors, height gauges, thread and roughness testers. And we offer full dimensional inspection reports for parts.
We offer various packaging methods to prevent damage and ensure easy handling. Custom packaging is available, commonly using EPE foam and bubble wrap.
We are a 15-year-old custom CNC machining parts manufacturer with multiple certifications. These include ISO 9001:2015, IATF 16949:2015, and SGS on-site inspection reports.
Is a chain catcher worth it?
A bike chain catcher prevents the chain from dropping off the chainring, reducing drivetrain wear and potential damage. For riders using narrow-wide, oval, or single-chainring setups, it enhances reliability and minimizes mechanical issues.
What is a chain catcher on a bicycle?
A chain catcher bicycle is a small component mounted near the front derailleur or chainring. It guides the chain, preventing it from dropping inward during shifts or under load. CNC-machined catchers offer precise alignment, durability, and compatibility with various bike types.
How to mount a chain catcher?
Mounting a bike chain catcher requires aligning it with the chainline and front derailleur height. Most are installed using bolts or clamps provided in the kit. Ensure proper clearance for smooth chain movement. For custom CNC catchers, VMT provides pre-drilled mounting points and reference surfaces to simplify accurate installation.
What is the typical lead time for custom chain catcher orders?
For custom CNC bike chain catchers, typical lead time depends on batch size, material, and complexity. Small prototype orders usually take 2–3 weeks, while larger production batches may require 4–6 weeks.
Can VMT produce lightweight chain catchers without compromising strength?
Yes. Using multi-axis CNC machining, VMT can optimize wall thickness, add reinforcement zones, and remove excess material. This produces lightweight bike chain catchers while maintaining strength and durability. Each part is analyzed for functional performance and tested to ensure reliability under riding conditions.
Are high-performance racing bikes suitable for CNC chain catchers?
Absolutely. Road bike chain catchers can be custom-machined to meet racing demands, ensuring minimal weight, precise alignment, and smooth chain retention. VMT’s CNC process allows for weight optimization and compatibility with high-performance drivetrains, making them ideal for racing bikes.
