Carbonda CFR-505 SL

SOLD AS A FRAMESET by an OEM/ODM factory (the page's only call to action is "Get a quote"; service "Custom paint&design"). The page's spec table lists "Gravel handlebarsizes : 80x400, 90x420, 90x440, 100x440" (stem length x bar width, mm) for this integrated-cabling frame; the maker's own catalogue (https://carbonda.com/upload/soft/240914/carbonda-sports-catalog.pdf, page 7) names that one-piece bar CHB-CGB02 (Type Gravel, sizes 80*400 90*420 90*440 100*440) and publishes no stem angle, bar reach, bar drop or stem clamp stack for it, so no cockpit geometry can be recorded. Headset: 1-1/2" x 1-1/2" ACR (page). Seat post: 27.2 mm round, "Zero or 25mm setback" (page; recorded per size as posts 0 and 25). Frame: T800/T1000 mixed carbon, EPS moulding, T47-68 mm bottom bracket, UDH, flat mount disc, 160 mm rotors, 12x100 front and 12x142 rear thru-axles, max tyre 700C x 42 mm or 650B x 47 mm, max chainring 52-36T or 42T; frame (M) 1000 +/-50 g, fork 420 +/-15 g.

The CFR-505 SL page heads the frame "ALL ROAD" ("Suitable for various scenarios", "Racing geometry All road setting"), lists "FrameSizes: 48/51/54/57/60cm" in its spec table and links seven PDFs: two fork drawings (CFO-505-SL integrated and non-integrated cabling) and one frame drawing per size named XS, S, M, L and XL. There is no geometry sheet, so each size's row is taken from that size's own drawing (title block "CFR-505 SL-<size>-B", drawing no. CFR-505 SL-<size>-B-UDH-009, R0, dated 2023.04.12; PDFs plotted 2024-07-10). SIZE LABELS are the drawings' XS/S/M/L/XL exactly; the page's 48/51/54/57/60 cm list is in the same order but the maker never pairs the two, so it is kept here only as a note. DIMENSION MAPPING (from the drawing's own dimension lines): top_tube_effective = the horizontal dimension from the seat tube axis to the head tube axis at head tube top height (515.0 / 531.0 / 547.00 / 570.0 / 591.0); reach = the horizontal dimension from the BB centre's vertical to the head tube top (355.7 / 364.7 / 378 / 388 / 403); stack = the vertical dimension from the BB centre to the horizontal through the head tube top (521 / 543.7 / 570.8 / 595 / 614.0), so the stack datum is the bare head tube top; head_tube_length = the dimension along the head tube (110 / 130 / 155.0 / 180 / 200, each +/-0.5); head and seat angles are the drawn arcs to the axle line; wheelbase = the horizontal axle-to-axle dimension (+/-2); front_centre = the straight BB-centre-to-front-axle dimension (+/-2); chainstay = "RC:420" (BB centre to rear axle, +2/-0, every size); bb_drop = the vertical "73.00" between the axle line and the BB centre (every size); seat_tube_length = the dimension along the seat tube from the BB centre to the top of the seat tube (468.3 / 498.3 / 520 / 558 / 588, each +/-1). fork_offset 51 is the drawing's dimension between the steering axis and a parallel line through the front axle ("51.00" on XS, M, L, XL, "51.0" on S), which is the fork offset by construction although the drawing does not write the word; the fork's axle-to-crown length along the steering axis is drawn as 384 on every size (not a schema field). The drawings also dimension the seat stay (393.0 / 403.7 / 416.0 / 434.4 / 452), the chainstay's straight run "372.82" (372.83 on XL), a minimum seatpost insertion ("greater than" 175.00 / 205.00 / 250.00 / 265.00 / 290.00) and draw the wheels at R358.00; none of these is a schema field. Note that M is drawn at 73.5 deg while XS, S, L and XL are drawn at 73.0 deg; each drawing closes its own top tube (reach + stack / tan(seat angle) reproduces the printed top tube within 0.3 mm on every size), so the 73.5 on M is not a misread. NOT PUBLISHED and therefore null: standover, trail, stock stem length, stock bar width. tyre_width_mm is null because the maker states only the maximum tyre (700C x 42 mm), not the tyre the geometry assumes. MODEL YEAR: none printed; drawings dated 2023-04-12; model_year null. CROSS-REFERENCE: Bike Insights lists this frame as Carbonda CFR505, version 2023, build SL (see cross_check); Panda Podium, Geometry Geeks and 99 Spokes were not used. Source: pdf (the maker's product page publishes no geometry table; its "File download" list links one AutoCAD frame drawing per size, https://carbonda.com/upload/download/CFR-505-SL/CFR-505-SL-XS-UDH.pdf, -S-, -M-, -L- and -XL-UDH.pdf; the dimension text is plotted as outlines with no text layer, so every number was read by eye from 300 dpi renders of the five drawings; PDFs NOT stored in the repo)
