QuickPro GR:One

INTEGRATED one-piece bar/stem: CANWIN AELOUS SSL (CANWIN is the brand's accessory label; the US frame page lists "Handlebar: CANWIN AELOUS (Outward Expansion)" i.e. flared drops; the AU page calls it "Lightweight integrated handlebar"). NOTE the US GR:ONE FRAME (USD 2,099) ships Frame / Fork / Headset / Axles / Carbon Seatpost only - the bar is chosen separately ("Add a handlebar to complete your frameset" on the Quick Ship listing); AU complete bikes include it. Bar widths (top/hoods -> drop/bottom width): 380 mm (bottom 440 mm), 400 mm (bottom 460 mm), 420 mm (bottom 480 mm); the GR:ONE build configurator on quickprousa.com also lists 440 mm (bottom 500 mm). Default width 400 mm ("Handle Bar Length (default 400mm)"), size independent. Stem lengths: 70 / 80 / 90 / 100 mm, default 100 mm ("Stem Length (default 100mm)"), size independent; the standalone AELOUS SSL Handlebar listing (quickprousa.com/products/aelous-handlebar-1, USD 380, Raw Carbon Black) offers 380/400/420 x 70/80/90/100 only. Bar reach, bar drop, flare angle, stem angle, stem/clamp height and bar weight are NOT published on the brand sites (product photos show a stem printed "WIDTH 400mm LENGTH 80mm" only). Headset: 52 x 52 mm ("HT 52x52 mm" on the US page; fully internal routing). Spacers: "Spacers Package 40mm" (USD 19) sold separately - individual spacer heights and max spacer stack NOT published; headset cover / top cap height NOT published. Seatpost: carbon seatpost included with the frame, 169 g +/-5%; lengths 35 cm (default) or 40 cm; offset -20 mm setback (default in the GR:ONE configurator, sold separately as "SEATPOST -GR:ONE -20mm SETBACK", USD 179, 35/40 cm) or zero setback ("Zero Setback (ARONE Seatpost)", the AR:ONE/GR:ONE zero-offset post, USD 179, 35/40 cm). Crank length options in the build configurator: 165 / 170 mm (default 170), plus 172.5 mm on the AU builds. Fork: one fork only (400 mm axle-to-crown, 459 g +/-5%); no wide/narrow option on the GR:ONE (that is an ER:ONE option).

IDENTICAL table (rows lettered A-K plus Reach/Stack) on the brand's AU store https://quickproaus.com/products/gr-one-grx-di2-1x12 with geometry diagram https://quickproaus.com/cdn/shop/files/gr-one-geometry.png. The Chinese parent site (quick-bikes.com.cn) was not attempted this time - it returned WAF captcha / 504 on every attempt during the ER:ONE collection. COLUMN MAPPING (brand label -> field): "Size / ST Length (mm)" -> seat_tube_length and size label; "Virtual TT (mm)" -> top_tube_effective (horizontal top tube, letter B in the diagram); "ST Angle" -> seat_tube_angle; "HT Angle" -> head_tube_angle; "HT Length" -> head_tube_length; "RC Length (mm)" (rear centre, letter F, drawn BB centre to rear axle) -> chainstay; "Wheel Base" -> wheelbase; "Fork Rake" -> fork_offset; "BB Drop" -> bb_drop; "Standover" -> standover (letter K, drawn vertically from the ground to the top tube). "Fork Length (mm)" 400 all sizes (axle to crown, letter J) is published but has no schema field. STACK DATUM: the AU diagram draws Stack vertically and Reach horizontally from the bottom bracket centre to the top of the head tube (standard convention); the brand states no datum in words. SEAT ANGLE CONVENTION: labelled only "ST Angle (deg)" - the brand does not say effective or actual; the diagram draws angle C at the seat tube centreline where it meets the BB, which reads as the actual tube angle, but the frame has a near-straight seat tube so effective and actual should be close. Values are as published even where odd: XL is steeper (73.8) than L (73.3). Front centre and trail are NOT published (left null). stock_stem_length 100 and stock_bar_width 400 are the size-independent configurator defaults ("default 100mm" / "default 400mm"), not a per-size spec - the AELOUS stem range is 70-100 mm. Stack-to-reach: 1.42 / 1.43 / 1.45 / 1.46 / 1.48. SIZE NAMES: the store uses XS/S/M/L/XL with the seat tube length as the numeric size (426/456/486/516/546); the sizing guide uses XS/SM/MD/LG/XL. SIZING GUIDE (brand image https://cdn.shopify.com/s/files/1/0677/7749/5105/files/GR_Sizing_Guide.png and AU text): XS 5ft0-5ft4 / 152-163 cm; SM 5ft3-5ft8 / 160-173 cm; MD 5ft7-6ft0 / 170-183 cm; LG 5ft11-6ft3 / 180-190 cm; XL 6ft2-6ft6 / 188-198 cm ("Sizing may vary based on rider proportions, build, flexibility, and riding style"). FRAME FACTS (US page): high-strength high-modulus carbon monocoque ("Monolith One Piece Construction"), frame 919 g +/-5% (size M), fork 459 g +/-5%, seatpost 169 g +/-5% (AU page says "Frameset weight of 879g"), head tube 52x52 mm, BB T47-68 mm threaded, thru-axles F 100x12 / R 142x12 mm, max tire 700x45c. Category: the store files it under "GRAVEL - RACE" ("All Terrain Racing Gravel"). MODEL YEAR: the chart is undated on the brand sites; US product record created 2025-10-24, AU GR:ONE records created 2026-03-03; sizing guide image versioned Feb 2026, AU geometry diagram versioned Aug 2026; no year is claimed, so model_year is null.
