Overview

Start with the size chart and an exact package quote. The current V5 catalog lists a 1,000 g size-54 UD-matte frame, with ±4% tolerance, and seven sizes. Our retained V1 source listed 1,100 g and five sizes. That is a document revision difference, not proof that a delivered frame changed. The nominal 700×35C limit does not approve every tire-and-rim combination. The exact ordered revision, included components and current mainland China price remain unverified.

A current price is not recorded.

Package contents are unconfirmed; do not subtract component costs from the allowance without an exact package quote.

Buying context

Before buying, verify Current mainland China quote, selected package, delivery and warranty route; Independent aero and stiffness test data.

Buyer checks

Match reach and stack to your requirements; confirm frame, fork, cockpit and hardware inclusions; obtain the delivered quote and warranty route. Check measured tire clearance with the actual rim and tire.

Use our frame-sizing guide to prepare the measurements before requesting a size recommendation.

Angles explicitly carry degree symbols; no general length-unit legend is printed in this table. Existing geometry range, claimed size-54 UD-matte 1,100 g ±4%, 35C maximum and package uncertainties are retained; no values are transferred to LCR017-D or SpeedZ.
Package confirmation
V5 lists cockpit dimensions and illustrates components but supplies no explicit order-specific inclusion list. Frame, fork, cockpit, seatpost, headset, spacers, axles, hanger and other hardware must be confirmed in a dated quote.

Angles retain degree symbols. The table has no general length-unit legend. V1 remains separately retained; do not mix revisions or transfer values to LCR017-D.

The current V5 manufacturer catalog documents the LCR020-D, with different weight and size/geometry data from retained V1. The exact ordered production revision, complete package and current delivered price remain unconfirmed. A component drawing is not an inclusion list.

Existing geometry range, claimed size-54 UD-matte 1,100 g ±4%, 35C maximum and package uncertainties are retained; no values are transferred to LCR017-D or SpeedZ. The page shows a manufacturer CAD illustration, not a product photograph; it was not misclassified or published under the photo-only media contract. Neither LCR020-D nor the pictured LCR017-D is identified as SpeedZ. No dated offer, stock or checkout is established.

  5. LightCarbon 2026–2027 V5: exact LCR020-D and LCR018-D panels

    LightCarbon · Manufacturer catalog pixel reviewIdentity: High · Specification: High · Price: None · accessed 2026-10-11

    Current downloads index linked V5; direct HTTPS retrieval succeeded. Exact physical PDF page 1 left panel (printed 01) identifies LCR020-D; the right panel is LCR017-D and is excluded. Exact physical page 3 (printed 02) identifies LCR018-D. Rendered pixels reviewed, text extraction used only as an aid. V5 changes LCR020-D frame mass and size/geometry data relative to retained V1; no silent equivalence to a delivered production revision. Component labels and drawings do not establish an ordered package. LCR018-D size-580 front center is 616.4 in V5 versus 606.4 on the current page; standover calculation headings also differ. No retail offer, independent test, or fresh purchase source-policy inference.
