- Factory_weight_context
- Manufacturer social post claims 7.8 kg for 7120, 7.5 kg for 7170 and 7.2 kg for 8170; none is mapped to the retained mechanical-105 package
- Frame_stiffness_status
- No independent numeric exact-platform stiffness result found after 50 registered source areas
The official Chinese catalog maps 速7 to LCR017-D. Its 32C maximum therefore applies to the retained platform, but factory 7.8/7.5/7.2 kg social claims are not assigned to the retained mechanical-105 build.
Buying context
Before buying, verify Exact retained mechanical-105 bill of materials and complete-bike weight basis; Current checkout and domestic warranty/after-sales entity; Controlled independent exact-frame stiffness evidence.

These sources support this model page; individual claims retain the confidence of their cited source.
Opened public detail from the manufacturer account visibly states complete-bike weight claims of 7.8 kg for the 7120 configuration, 7.5 kg for 7170, and 7.2 kg for 8170. These are configuration-specific social-post claims retained for the separate Speed7 candidate; they are not propagated to the published SPEEDZ variant or treated as a measured universal weight.
Opened public detail identifies an exact LC-SPEED 7 customer-return post and visibly includes a PROX wheel hashtag. No exact wheel model, depth, or complete-bike BOM is exposed; retained only as candidate context.
42 screenshots and 160 listing observations were normalized into 133 model groups. Listed, coupon, subsidy, and first-order conditions are preserved in the research ledger. Screenshots, purchase source identities, and private data are not redistributed.
The official Chinese catalog renders the brand as “LightCarbon轻碳” and explicitly maps 速7 to LCR017-D. It publishes the exact platform material, size-52 matte-frame 870±30 g claim, 390±15 g fork, 160±10 g seatpost, 32C maximum and geometry.
Current exact LCR017-D page still publishes construction, size-specific weights, 32C maximum, T47-68, UDH, cockpit, ISO4210 and two-year warranty, but no public retail price or mainland checkout.
