Import Chain Wheel & Crank — Buy in Bulk from Supplier in China

This chain wheel and crank set is engineered for precision gear shifting and lightweight performance, designed for compatibility with a broad range of bicycle models. The components are manufactured using industrial-grade steel or aluminium alloys, ensuring durability under cycling loads typical of both recreational and competitive use. The listing specifies a focus on OEM and aftermarket applications, with the supplier based in Pingxiang Hegumiao Industrial Area, Xingtai, Hebei.

The chain wheel typically features a tooth count range of 32T to 50T, with standard BCD (bolt circle diameter) measurements of 110mm or 130mm for road and mountain bike configurations. Cranks are usually forged from 7075-T6 aluminium or chromoly steel, offering a balance of strength and weight savings. Surface treatments such as anodising or nickel plating are standard to resist corrosion and wear, while the crank arm length commonly spans 170mm to 175mm for adult frames.

These components serve OEM bicycle manufacturers, bike assembly plants, and retailers stocking replacement parts. Buyers in Europe and North America frequently source these for mid-range and performance bikes, where consistent gear engagement and pedal efficiency are critical. The supplier’s location in Hebei, a hub for bicycle part production, supports cost-effective bulk shipping, with Incoterms like FOB Qingdao often used. Confirm MOQ, packaging, and material certifications directly with the supplier before ordering.

Hebei Xingtai City Tianyuan Bicycle Co., Ltd operates from Pingxiang Hegumiao Industrial Area in Xingtai, Hebei Province, a region recognized for its concentration of bicycle component manufacturers. The company is listed as an imported-tier supplier, indicating it primarily serves international buyers. Its address places it within a dedicated industrial zone, which often correlates with access to specialized machinery and logistics infrastructure for bulk exports.

The supplier’s trust tier is classified as harbor, suggesting a baseline level of verification for export readiness. However, the response rate and average response hours are currently recorded at zero, which may indicate limited recent engagement or a need for direct outreach to confirm lead times and production capacity. The company’s focus appears to be on producing chain wheels and cranks, with no additional product lines or certifications explicitly stated in the available profile.
