Carbonda CFR-707

INTEGRATED one-piece bar/stem offered with the frame: Carbonda CHB-CGB02 (catalog type "Gravel"), listed in the CFR-707 spec table as "CGB02 size: 80x400, 90x420, 90x440, 100x440" (stem length x bar width, mm); the maker does not map a CGB02 size to a frame size, so stock_stem_length and stock_bar_width are null. CGB02 bar reach, drop, flare, stem angle, clamp height and maximum spacer stack are NOT published on carbonda.com or in the 2024-09 catalog. Catalog alternative: CHB-CGB01 conventional gravel drop bar (type "Gravel") in 380 / 400 / 420 / 440 mm, which needs a separate stem. Headset: "1-1/2" * 1-1/2" ACR" (cables routed internally through the headset; the page lists "Integrated cabling"); the size-M engineering drawing shows 52.1 mm (+0.05/-0) bearing seats top and bottom and a 57 mm head tube outer diameter, so both bearings are 1-1/2 in. Seatpost: "Seat post diameter: 27.2 MM", "Seatpost offset: Zero/25mm setback" (catalog posts CSP-056 27.2 mm x 350 or 400 mm, 0 mm offset, and CSP-006 27.2 mm x 350 or 400 mm, 25 mm offset); the drawing shows an internal wedge seat clamp at the seat tube top. Fork: CFO-707 (catalog), 590 g +/- 15 g, 12x100 mm thru axle, axle-to-crown 400 mm and offset 50 mm on every size (columns F and OT of the geometry table).

COLUMN MAPPING read from the diagram: S = seat tube length along the seat tube from the bottom bracket centre to the top of the seat tube (centre-to-top); SC = seat tube angle, the angle between the horizontal through the BB centre and the seat tube centreline; O = horizontal top tube, drawn at the height of the top of the head tube from the head tube axis back to the extended seat tube centreline (an effective top tube); HS = head tube length along the head tube axis; HC = head tube angle; F = fork length axle-to-crown (400 on all sizes, no field in this schema); OT = fork offset; WB = wheelbase; FC = front centre (BB centre to front axle); RC = rear centre (BB centre to rear axle), recorded as chainstay; G = bottom bracket drop. STACK DATUM: Stack is drawn as the vertical from the BB centre to a horizontal line through the top of the head tube (the frame's head tube top face, on its axis) and Reach as the horizontal from the BB vertical to the head tube axis at that same line; no headset cover or spacer is included. SEAT ANGLE: labelled only "SC" with no wording; the diagram and the size-M engineering drawing show a straight seat tube whose centreline passes through the BB centre, so the actual and effective angles coincide, but because the maker never says "effective" the flag is left null. UNITS: mm and degrees (the drawing title block says unit mm; the table prints angles with a degree sign). SIZE NAMES: XS / S / M / L / XL / XXL (page: "Sizes: XS/S/M/L/XL/XXL"); the maker publishes no rider height guide. NOT PUBLISHED, so null: standover, trail, per-size stem length and bar width. SIZE-M ENGINEERING DRAWING (https://carbonda.com/upload/download/CFR-707/CFR-707-M-UDH.pdf, drawing no. CFR-707-M-UDH-FB-003, design date 2023-06-14, edition R0, scale 1:1, mm) repeats 560.0 / 390.4 / 572.7 / 490 +/-1 / 150 +/-0.5 / 70.5 deg / 73.5 deg / 1050.7 +/-2 / 625.3 +/-2 / RC 435 (+2/-0) / 50 / 400 exactly as the table and gives the BB drop as 69.7 +/-0.2 where the table prints 70; the table value is recorded. The same drawing carries an unlabelled vertical dimension of 813.6 mm from the ground line (wheel drawn at R361, i.e. a 722 mm rolling diameter) to the top of the top tube at the rear of the two top-tube accessory bolts (the bolts are 64 mm apart, the front one 80 mm behind the head tube axis); that is a standover-type height for size M only, the maker does not name it and the other sizes' drawings were not fetched, so standover stays null. OTHER FRAME FACTS from the page: "Carbon fiber gravel bike / adventure bike / traveling bike", T700 and T800 carbon mix, UD weave, frame (M) 1300 +/-50 g including alloy parts, fork 590 +/-15 g, BSA 68 mm bottom bracket, flat mount, 160/180 mm rotors, 12x100 mm front and 12x142 mm rear thru axles, UDH, max tyre 700x50C / 650Bx2.1 in (53.3 mm), max chainring 52-36T / 46T, rack and fender compatible, one-piece EPS moulding, custom paint. MODEL YEAR: Carbonda does not date the model; the drawing is from June 2023, the geometry PDF from August 2024, the page photos from September and October 2024 and the catalog from September 2024, so this is the frame sold from 2024 on; model_year is left null rather than guessed.
