LightCarbon LCG074-D micro-suspension gravel frameset
Current exact LCG074-D page still publishes the integrated-cockpit frameset specification, micro-suspension pivot, storage, weights, clearance, standards and warranty, but no public retail price or mainland China checkout.
LightCarbon road frames catalog
The three-page official Road Frames category establishes the manufacturer catalog relationship for current and older road, rim-brake, disc-brake, triathlon and track models. Exact-model specifications come from the linked product pages or current catalog PDF rather than category-card snippets.
LightCarbon says Xiamen LightCarbon Composite Technology was founded in 2012, designs and manufactures carbon frames and components in Xiamen, operates separate frame and rim production lines, employs around 80 people in its frame factory, and provides OEM/ODM work as well as its house-brand products. These are company-reported facts.
LightCarbon LCG074-D official product page price recheck
The current exact LCG074-D manufacturer page describes the integrated-handlebar micro-suspension gravel frameset and component package (frame, fork, handlebar, stem and seatpost) but provides no numeric price or currency. It says to contact the manufacturer and shows no current stock or availability context. No price observation is supported.
