Carbonda CFR-1056

SOLD AS A BARE FRAME by an OEM/ODM factory (page: "Get a quote"; service "design and painting"); no handlebar, stem, seatpost or spacer kit is specified, so stock_stem_length and stock_bar_width are null and no stem angle, bar reach/drop, spacer stack or headset-cover height is published; integrated_cockpit is null because the cockpit is the buyer's choice. HEADSET (page spec table): "1-1/2" * 1-1/2" ACR" (1.5 in upper and lower bearings, ACR-type cable routing through the headset); page features "Integrated cabling" and "compatible hidden cable routing". The size 490 frame drawing (CFR-1056-490-FB-001, R0, 2019-06-29) dimensions the head tube bore at 52.1 mm (+0.05/-0) top and bottom with a 57 mm outer diameter at both ends and labels the headset "NO.55R 1.5 in". That drawing and the assembly drawing (CFR-1056-001-ASM, R3, 2021-06-16) also show cable entry on the down tube behind the head tube (left port with a snap-in two-piece stop FB-CB-060, slot 24 x 8.5 mm; a 6 mm Di2 hole on the right of the top tube, drawing note "A: top tube has a Di2 hole"), with PE liners 7.2 x 6.4 mm (brake) and 2.2 x 1.7 mm (front and rear derailleur / Di2) fitted inside the frame; those drawings pre-date the current page, so the frame appears to accept either through-headset (ACR) or down tube entry, which the maker does not spell out. Hardware on the assembly drawing (English readings of the Chinese parts list): item 1 FB-CL-182/183/184 "clamp/tightener", one part number for size 430, one shared by 460/490 and one shared by 520/550, drawn as a wedge with a bolt, test-fitted then removed and shipped loose, which reads as an internal seatpost wedge clamp although the maker does not name it in English; CFR-AS01 blanking stop; Di2 8 mm and 6 mm plugs; CFR066 removable front derailleur mount with two M5 x 16 screws; CFR-606 thru-axle rear derailleur hanger (inner and outer aluminium parts, M4 x 19 screw); CFR-CRD18 guide plate; CFR-1056 dust cover; four M5 x 12 bottle bolts. SEATPOST: the size 490 drawing dimensions the seat tube bore at 27.2 mm (+0.15/-0), i.e. a standard round 27.2 mm post; no seatpost, offset or clamp is stated on the page. FORK: full carbon, 380 mm axle-to-crown (table column F, all sizes), 45 mm offset (column OT, all sizes), flat-mount disc, weight 480 +/- 15 g; front axle spacing is not dimensioned on the fetched drawings. REAR: 12 x 142 mm thru-axle (490 drawing: dropout spacing 142 +1.5/-0.5, 12 mm axle bore, flat mount on an STV06 aluminium insert). FRAME (page spec table): BB86 or BSA-68 (the 490 drawing is the BSA version with a 68 +/- 0.5 mm shell); max tyre 700 x 32 mm; frame weight size M 1050 +/- 50 g; 100% Toray carbon, UD weave, EPS moulding, "All in one piece"; "EN standard test (in house)".

OEM/ODM carbon frame factory; the page's only call to action is "Get a quote"). The product page https://carbonda.com/road/cfr-1056.html carries a spec table (Model No FM1056, USE Disc Road bike, Size XS S M L XL, weights, headset, BB, brake, max tyre) and a "File download" list linking seven PDFs: CFR-1056-430/460/490/520/550 (one frame drawing per size), CFR-1056-Assembling-drawing and CFR-1056-Geometry; the geometry table exists only in that Geometry PDF and nowhere in the HTML. TABLE LEGEND (columns exactly as printed, mapped from the drawing on the same sheet): SIZE = XS/S/M/L/XL; S = seat tube length, BB centre to top of seat tube along the tube axis (430/460/490/520/550, the same numbers Carbonda uses in the per-size file names, hence the "XS / 430" labels here); SC = seat tube angle, drawn between the horizontal axle line and the seat tube axis; O = top tube, drawn HORIZONTAL from the extended seat tube axis to the head tube axis at the height of the head tube top, i.e. effective top tube; HS = head tube length along the head tube; HC = head tube angle to the horizontal; F = fork length along the steerer axis, crown to front axle (380 for every size; not a schema column, kept in cockpit_options); OT = fork offset (45 for every size) -> fork_offset; WB = wheelbase, horizontal axle to axle; FC = front centre, BB centre to front axle in a straight line; RC = rear centre, BB centre to rear axle in a straight line -> chainstay; G = BB drop, vertical from the axle line down to the BB centre; Reach = horizontal from a vertical through the BB centre to the head tube axis at the top of the head tube; Stack = vertical from the BB centre to the horizontal through the top of the head tube. STACK DATUM: BB centre to the centre of the top face of the head tube (the dash-dot datum line on the drawing runs through the head tube top, no headset cover or cone is included). Values are kept exactly as printed, including HS 172.6 for L and Reach 385 for L (printed without a decimal) and the integer angles 72 and 73. NOT PUBLISHED and therefore null: standover, trail, stock stem length, stock bar width. The size 490 frame drawing repeats the M row exactly (490 / 546 / 157 / 72 deg / fork 380 / offset 45 / WB 998.6 / FC 594.6 / RC 415 / drop 73 / reach 380.8 / stack 571.2) and draws the wheels at R347 (694 mm diameter); it also carries an unlabelled vertical dimension of 795.9 from the ground line up to the top tube near the head tube junction, which may be a standover-type height but is not labelled as such and is NOT recorded. MODEL YEAR: none stated anywhere; the page photos were uploaded 2024-08/09 and the geometry sheet plotted 2024-08-23, but the size 490 frame drawing is dated 2019-06-29 (R0) and the assembly drawing 2021-06-16 (R3), so this geometry has been in production since at least 2019; model_year left null. CATEGORY: the page heads the bike "Endurance" with "Comfortable Geometry Settings" and "Max tire up to 700x32c", and the ROAD range menu lists it beside CFR-1136 Endurance ROAD and CFR-VT02 Race AERO, so endurance road. Source: pdf_table (the maker's product page publishes the geometry only as a linked one-page CAD PDF, https://carbonda.com/upload/download/CFR-1056/CFR-1056-Geometry.pdf, an AutoCAD 2010 plot dated 2024-08-23 carrying the labelled frame diagram and a 14-column table; lengths taken from the PDF text layer, the two angle columns read from the rendered page because their degree glyphs are plotted as outlines; PDF NOT stored in the repo)
