Stack and reach
How high and how far forward the top of the head tube is, from the bottom bracket. They are the two numbers that decide whether a frame can be set up like yours.
BB, or bottom bracket
The axle your cranks turn on, in the middle of the frame. Every number on this site is measured from it, because it is the one point that sits in the same place on every bike.
Headset cover
The little cap on top of the head tube, under your spacers. Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".
Stem clamp, and its centre
The collar on the steerer that your stem bolts to. I need the middle of it. Where a maker gives only the height, I assume halfway up and say so on the answer.
Steerer
The tube coming up out of the fork. The cover, the spacers and the stem all sit on it, and it is the thing a mechanic cuts to length.
Bar reach
How far forward the hoods sit from the middle of the bar. Two bars on the same stem can put your hands 20 mm apart, which is why I ask.
Setback
How far your saddle sits behind the bottom bracket.
Drop
How much lower your bar is than your saddle.
Rails, and the rail centre
The two rods under your saddle, and the middle of the straight part of them. That midpoint is the point I use, because it is the one you can find with a tape.
The band
How far out I could be, in millimetres, and why. It is a straight sum of everything I had to assume rather than a clever average, so it errs wide on purpose.
wb, stand, trail
Wheelbase, standover and trail: how long the bike is, how high the top tube is where you straddle it, and how steady the steering feels. I show them against your bike, and I leave them out when the maker does not publish them.
est.
Estimated: a number I worked out rather than read off the maker's table. Anything marked this way can move if the maker publishes the real one.

Cockpit and seatpost, in the maker's words · 345 words
INTEGRATED one-piece tri/TT aero cockpit: "TR:ONE" handlebar (Key Specifications: Handlebar = TR:ONE). The TR:ONE FRAME listing on quickprousa.com says it ships Frame / Fork / TR Handlebar / Seatpost / Accessories; the same cockpit is also sold alone as "TR:ONE COCKPIT" (https://www.quickprousa.com/products/tri-aero-bar, USD 599 without base bar / USD 799 with base bar). Feature copy: "An extended, one-piece aero cockpit with multi-point adjustable extensions lets you fine-tune armrest width, reach, and angle". Dimensions read from the maker's cockpit drawing (https://cdn.shopify.com/s/files/1/0677/7749/5105/files/a879a79858534fd7190def742be063c2_jpg.jpg, shown on both the frame and cockpit pages): base bar width 400 mm; armrest width adjustable 160-190 mm; extension length adjustable 370/380/390/400 mm; extension tip angle 17.7 deg then 50 deg upsweep (ski-tip); armrest riser "adjustable washers" 35/50/65 mm and 80/100 mm; extension shim "adjustable washers" 10/20/30 mm; "adjustable angle washer" 15 deg / 10 deg; a part dimension of 237.10 mm is printed on the drawing (the extension/armrest cradle length, label unclear). No conventional stem: stem length, stem angle and headset spacer stack NOT published (head tube is a straight 52x52 mm). NOTE the US frame-page configurator (Globo option set 1340416, bound only to this product) still offers "Handle Bar: No Handle Bar / ZEPHYR SSL" with "Handlebar Length (default 400mm)" 340-420 and "Stem Length (default 100mm)" 70-140 - these are the road ZEPHYR SSL drop-bar options and look copied from the road-frame template; they do not describe the TR:ONE cockpit. Same configurator: Group Set = No Group Set ("Frame Only") / Shimano Dura Ace Di2 / SRAM RED 2x12; size buttons XS/S/M/L with help texts 470/510/557/574 that do NOT match the geometry table's seat tube lengths 528/537/557/572 (stale help text, ignored). Seatpost: proprietary aero seatpost included with the frameset (175 g +/-5%); length and offset NOT published; no seatpost setback option is offered for the TR:ONE (unlike ER:ONE -15 mm and GR:ONE -20 mm posts). Complete bikes (TR:ONE DURA-ACE / RED / RIVAL AXS 2x12) ship RORE TT/TR 88 front + TT/TR Disc Aero Pro rear, SAMASSI 3D Carbon Bow saddle, 700x28c tubes; crank options 165 or 170 mm with 50-34T or 52-36T.

How I read the maker's table
The table is IDENTICAL on the brand's Australian site https://quickproaus.com/products/tr-one ("TR:One", created 2026-03-05, sizes XS/S/M/L, AUD 5099) and on the US complete-bike page https://www.quickprousa.com/products/tr-one-dura-ace-tt. The Chinese parent site quick-bikes.com.cn was not attempted (WAF/captcha on every previous attempt, see quickpro.json). No aggregator was consulted. MODEL YEAR: the maker prints no year; 2026 is the launch/pre-order year (US record 2026-01-12, AU record 2026-03-05) and is what the task asked for. SIZE NAMING: XS/S/M/L; the US table heads columns "XS (528)" etc. and the AU table "XS / 528", the number being row A seat tube length in mm (AU label: "Frame Size / Seat Tube Length"); AU sizing guide also calls them XS/SM/MD/LG. DATUMS (from the diagram): STACK = vertical from BB centre to the top of the head tube; REACH = horizontal from BB centre to the top-centre of the head tube; B = top tube measured horizontally from the seat tube axis to the head tube top (US label "Top Tube Length", AU label "Effective Top Tube Length" - stored as effective); A = seat tube length along the seat tube from BB centre; K = standover height from the ground to the top tube; I = BB drop below the axle line; H = fork offset/rake; TRAIL is drawn at the ground contact. ROW J: labelled "Front Center (mm)" = 370 on every size, but 370 mm cannot be a front centre (wheelbase minus chainstay gives 547/566/596/625) and in the diagram J is drawn along the fork from crown to axle, i.e. fork length (axle to crown), exactly as the ER:ONE table's row J (373 mm). Treated as a mislabel: front_centre left null, 370 mm recorded here as fork axle-to-crown. stock_bar_width 400 = base bar width printed on the maker's cockpit drawing (integrated cockpit, size independent); stock_stem_length null (no stem). RIDER HEIGHT (TR_Sizing_Guide.png on the US page, text on the AU page): XS 155-165 cm (5ft1-5ft5), S 163-175 cm (5ft4-5ft9), M 173-185 cm (5ft8-6ft1), L 183-196 cm (6ft0-6ft5). FRAME: "High-Strength High-Modulus Carbon Fiber"; head tube 52x52 mm; T47-68 mm threaded BB; thru-axles F 100x12 / R 142x12; max tyre 700x32c; flat mount disc; weight frame 1219 g, fork 574 g, seatpost 175 g (all +/-5%); 1.2 litre concealed hydration bladder, removable storage box, computer mount included; USD 3599 frameset. Colours: Hunter (Shadow) Black, Pulse Purple / Electric Violet, Aurora Blue.
