Import Bicycle Frame 3 — Buy in Bulk from Supplier in China

The Bicycle frame 3 from Ruifeng Co., Ltd targets riders seeking sub-kilogram road frames with expanded size coverage. It employs 3K, 12K, or UD (unidirectional) carbon fibre, with finished weights between 960 g and 1020 g across four frame sizes: 48 cm, 51 cm, 54 cm, and 57 cm. The 57 cm option extends sizing for taller riders, a segment often underserved in lightweight frame offerings.

UD carbon fibre differs from woven 3K and 12K in that fibres align in a single direction rather than crossing at 90 degrees, allowing engineers to orient strength precisely along load paths and reduce resin-rich overlap areas. This can yield marginal weight savings and tuned stiffness compared to woven alternatives, though aesthetic appeal varies. The 960-1020 g range places these frames in contention for hill climb and gran fondo builds where cumulative elevation gain amplifies the benefit of every gramme saved.

Intended buyers include custom bike builders, cycling team equipment managers, and retailers serving performance-oriented road cyclists from 165 cm to over 190 cm in height. The size 57 cm at 1020 g upper limit suggests Ruifeng Co., Ltd has prioritised weight containment even at larger tube dimensions. Prospective purchasers must confirm fork crown clearance, derailleur hanger specification, and cable routing compatibility with electronic shifting systems before specifying builds.

Ruifeng Co., Ltd is located at 113#Bulong Road, Buji, Shenzhen 518112, Guangdong Province, China. The supplier's platform profile indicates imported tier status and harbor trust tier, with a response rate of 0.00 percent and zero recorded average response hours. These signals suggest limited recent buyer engagement through platform channels, though direct communication may yield different responsiveness.

No verified production volume, factory floor space, employee count, or export history appears in the available data for Ruifeng Co., Ltd. The company lists carbon fibre bicycle frames as a primary offering with material and size flexibility. Buyers should conduct independent due diligence, including requesting business licence verification, factory audit reports, and sample frame inspection, before entering into contractual agreements or transferring deposits.
