Overview
A well-documented, practical 50C budget frame for a custom build, but not a full aero-shell or road-geometry answer.
Best for: budget custom builder, wide-clearance rider
Value assessment
Great buy around ¥4,200 or below
T47, UDH, 50C, storage, published weights, and direct factory support form the strongest balanced budget package.
The finished bike will normally cost far more than a Twitter complete.

Its published front-center, chainstay, BB-drop and wheelbase values do not reconcile within rounding under common horizontal or direct front-center definitions (about 5 mm). Preserve the manufacturer values; their definition or consistency remains unconfirmed. Confirm the affected dimensions before using them for fit calculations.

Each source is labelled by what it supports. Confidence applies only to that role.
Current exact LCG071S-PRO page publishes China origin, PayPal or bank-transfer payment, a direct inquiry form, specification, paid order options and a two-year warranty. It remains quote-based rather than a public checkout.
Company-reported factory and production history.
LightCarbon LCG071S-PRO current order options
Current exact LCG071S-PRO inquiry page exposes China origin, direct order configuration and payment routes. The default SP02 seatpost can be changed to SP03 for US$10, and a matching T47 bottom bracket is a paid option; the complete quote and mainland China delivery or return terms remain private.
LightCarbon ordering and payment FAQ
LightCarbon says retail buyers can order one frameset by email or the product inquiry form, receive a reply within 24 hours, and pay by PayPal, bank transfer, Western Union or credit card. It does not publish an exact-model price, delivery amount or mainland China return terms.
LCG071S-PRO owner purchase report
Current exact-model owner report states US$595 for the size-580 frame plus US$200 for custom paint. The retained price observation uses only the reported base frame amount and excludes paint, shipping and tax; it is not an official public offer.
LightCarbon LCG071S-PRO official package recheck
The exact LCG071S-PRO page lists a LightCarbon-specific carbon fork, stem sizes 90/100/110/120 mm, SP02 seatpost by default (SP03 costs US$10 extra), and says T47 bottom brackets are paid options not included by default. It identifies China as product origin and PayPal or bank transfer as payment methods. The down-tube storage bag is optional. Headset, spacers, axles, handlebar and the full small-parts package are not itemized as included. The page gives no public price, checkout, stock, shipping, tax or returns terms.
LCG071S-PRO owner purchase report
The exact-model owner report was displayed as posted three days before access. It reports US$595 for the frame, with US$200 custom paint and US$50 for post/saddle stated separately. The poster gives order, paint, dispatch and delivery dates of May 18, July 1, July 7 and July 31 without years. Treat the amount as a recent public owner report with transaction year and freight/tax basis unverified, not a current manufacturer offer or mainland China checkout.
LightCarbon LCG071S-PRO German product-page route recheck
The current German-language manufacturer mirror identifies the exact LCG071S-PRO, China product origin, sizes 49/52/55/58, PayPal or bank transfer, and a product inquiry form promising a reply within 24 hours. It shows no public price, stock, checkout, selected package, shipping, tax or return terms. Page sections inspected: lines 298–325, 327–345 and 468–475.
LightCarbon LCG071S-PRO frameset (current product page)
Current manufacturer page identifies item LCG071S-PRO and states T700/T800 carbon with one-piece 3D latex-mandrel molding. It publishes size-specific frame weights (including the downtube lid, +/-40 g), 49/52/55/58 geometry, threaded T47, UDH, 700x50C/650B 2.1/29er 1.95 clearance, ISO4210 testing, compatible mechanical and Di2 groupsets, and a two-year warranty. Its claimed 30% strength improvement is manufacturer marketing without a published protocol and is not treated as a stiffness measurement. Mainland China CNY checkout pricing is not exposed.

The live exact-model table matches all stored sizes and dimensions. Its published front-center, chainstay, BB-drop and wheelbase values do not reconcile within rounding under common horizontal or direct front-center definitions (about 5 mm).
