Velobuild GF-005

The frameset (USD 479 on the page, 2026-08-29) is ordered with a cockpit chosen in the order form. The maker's description block (HANDLEBAR: full carbon, 380 g) lists the integrated one-piece bar/stem as 400/90, 400/100, 420/100, 420/110, 440/110, 440/120 mm (width/stem length), or "Separate bar and stem" with bar 400 / 420 / 440 mm and stem 80 / 90 / 100 / 110 / 120 mm. The live order form offers more integrated combinations than the description: "Integrated bar size" 380/90, 380/100, 400/90, 400/100, 420/100, 420/110, 440/110, 440/120, 380/110, 420/90, 400/110 mm or "Separate Bar Stem"; "Bar Size" 400 / 420 / 440 mm (or "Integrated Bar"); "Stem Size" 80 / 90 / 100 / 110 / 120 mm (or "Integrated Bar"). No size-to-cockpit default is published, so stock_stem_length and stock_bar_width are null. NOT published on the page: stem angle, bar reach, bar drop, bar flare, stem/clamp stack height, spacer heights, maximum spacer stack, headset top cap height. Headset bearings: 1-1/2 x 7 mm lower and upper (the maker's wording; the frame is "full integrated cable routing" through the headset, and the page carries a note about a "New C Ring with Chip to Solve Headsets Play"). Fork: full carbon, 420 g, offset 50 mm, steerer tube length 300 mm, flat mount, thru axle M12 x 1.5 x 130 mm, max rotor 180 mm, max tyre 700C x 50C. Seatpost: full carbon, 230 g without metal parts, 400 mm long, aero profile, "single bolt pivot precise adjustment", ordered as "0 Setback" or "20mm Setback"; saddle clamp 7 x 7 mm rail, with a 7 x 9 mm clamp for carbon rails included; seat clamp integrated in the frame. Frame: full carbon, 1020 g (size M, clear coat, without metal parts), T47 threaded bottom bracket (ID 46 mm, width 86.5 mm), flat mount, rear thru axle M12 x 1.5 x 163 mm, max rotor 160 mm, max tyre 700C x 50C, UDH rear hanger (page heading), Di2 and eTap compatible, finish matte or glossy plus paint options.

The page has no HTML geometry table; the Description tab is a run of images and the geometry is one of them (GEOMETRY.jpg, CDN path dated 2025-03-09). The page's JSON-LD gives productID / sku / mpn "GF-005", brand "VeloBuild", price USD 479. MODEL YEAR: 2025 is the maker's own naming (page title "2025 VeloBuild Carbon Fiber Racing Gravel Bike Frame", URL slug the same, product image CDN paths dated 2025-04-23); the page is still live and selling on 2026-08-29 with a customer review dated 2026-08-13. TABLE LAYOUT: one row per size (XS, S, M, L, XL), columns lettered A-K on the diagram: A "BB center to top of" (header cut short; the diagram's A runs along the seat tube from the BB centre to the top of the seat tube) -> seat_tube_length; B "Effective top tube" -> top_tube_effective; C "BB offset" printed as -75 for every size -> bb_drop recorded as 75 (the minus sign is the maker's convention for a BB below the axle line, i.e. a drop); D "Chainstay length" -> chainstay; E "Seat angle" (degrees) -> seat_tube_angle; F "Head angle" (degrees) -> head_tube_angle; G "WB length" -> wheelbase; H "Head tube" -> head_tube_length; I "Fork offset" -> fork_offset (50 mm every size, matching the fork spec); J "Reach" -> reach; K "Stack" -> stack. All lengths in mm as printed. STACK DATUM: per the diagram, K (stack) is the vertical and J (reach) the horizontal distance from the BB centre to the top centre of the head tube; no headset cap or cover is included in the drawing. NOT PUBLISHED (null): standover, front centre, trail, stock stem length, stock bar width. Sizing guide: none on the page (the size selector is just XS/S/M/L/XL). Frame-size sanity: stack-to-reach 1.43 / 1.40 / 1.41 / 1.42 / 1.43; wheelbase minus chainstay gives an implied front centre of 581 / 602 / 618 / 639 / 660 (derived, so not stored).
