The LT RD301-D is a well-received all-road carbon frame from Chinese OEM Long Tang, offering good value with wide tire clearance and internal storage, but buyers should expect minor quality control issues and missing accessories.

The reviewer discusses the LT RD301-D frame from Long Tang, an OEM manufacturer in China. He built his bike around this carbon fiber frame, describing it as an all-arounder Allroad bike. He notes that the frame came with a fork, headset, seatpost, axles, and derailleur hanger.
