High Price from Legacy Brands

Western suppliers impose 30-50% premiums for brand heritage. Your margins are squeezed.

Inconsistent Quality

Unverified factories cause batch failures, heat treatment inconsistencies, and premature wear.

High Shipping Costs

Volatile freight rates and inefficient consolidation are eating into your total cost of ownership (TCO).

Long OEM/ODM Lead Times

Custom rear sprockets take 12-16 weeks from concept to delivery. You need speed.

Communication Barriers

Misaligned technical specs and slow response times delay your time-to-market.

Powerful Factory Direct

Our integrated supply chain (CNC machining, heat treatment, surface finishing) cuts out middlemen, delivering 30-40% cost savings.

Rigorous Quality Assurance

ISO 9001 certified. 100% dimensional inspection, hardness testing, and fatigue analysis on every batch of rear sprockets.

OEM/ODM Expertise

We design custom sprockets types for specific performance needs. From 520 to 630 pitch, we deliver prototypes in 2-3 weeks.

High-Speed Delivery

Strategic warehousing and consolidated shipping reduce your freight costs. Standard lead time: 15-25 days.

Q: What sprockets types do you offer for motorcycles?

A: We manufacture all standard types: rear sprockets, front sprockets (countershaft), and chainwheels. We cover 428, 520, 525, 530, and 630 pitch sizes in steel, chromoly, and 7075-T6 aluminum. Custom tooth profiles and offsets are available for OEM projects.

Q: What is the minimum order quantity (MOQ) for custom rear sprockets?

A: Our MOQ is 100 pcs for standard materials and 500 pcs for customized designs. For prototyping, we offer low-volume runs starting at 10 pcs to validate your design before mass production.

Q: How do you ensure consistent quality across batches of sprockets types?

A: We follow a strict ISO 9001 framework. Every batch undergoes: 1) Material chemical analysis, 2) Dimensional CMM inspection, 3) Hardness testing (Rockwell), and 4) Magnetic particle inspection for cracks. A full QA report is provided with every shipment.

Q: What are the typical shipping costs and lead times to the USA or Europe?

A: We optimize shipping by consolidating orders. For a standard 20ft container, sea freight to the US West Coast is approx. $2,500-$3,500 (variable). Lead time is 15-25 days for production, plus 20-30 days for sea freight. We offer CIF terms to simplify your logistics.

Q: Can you help with OEM branding and packaging?

A: Absolutely. We offer full OEM/ODM services, including laser engraving, custom packaging (blister pack, retail box, bulk), and barcode labeling. We've partnered with major brands in the US and EU to launch their private label sprocket lines.

Q: What payment methods do you accept?

A: We accept T/T (wire transfer), L/C (Letter of Credit), and for long-term partners, we can explore monthly credit terms. All payments are secured and compliant with international trade regulations.

James O'Neil | CTO, Texas Performance Parts

"We tested 6 factories across Asia. HEBEI WINDZONE's 7075 sprockets had the highest fatigue life. We've placed 3 repeat orders this year."

Sophie Laurent | Purchasing Manager, Lyon E-Bikes

"The OEM communication was flawless. They understood our CAD specs immediately and delivered prototypes in 18 days. Highly recommend their custom rear sprockets."

David Chen | Operations Director, Singapore Distributor

"Price, quality, and speed—they hit all three. The consolidated shipping saved us 22% on logistics costs compared to our previous supplier."
