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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.
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 hands sit than your saddle. On a riser bar I count the bar's rise, so the drop is that much less than it is to the clamp.
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.

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 54 drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm. A dashed tube is a number the maker left out (est.).
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Generic stem and barAssumedNo bar is listed for this frame.

Cockpit and seatpost, in the maker's words · 47 words
The Razha Tiagra build ships with a "MOST Alu" handlebar and a "MOST Alu" stem (the page's COCKPIT section). The page prints no bar width, reach or drop and no stem length or angle, and does not say which width and stem each frame size ships with.
OFFICIAL SOURCE, ARCHIVED: Pinarello's own product page "Razha Tiagra" (https://pinarello.com/global/en/bikes/road/endurance/razha/razha-tiagra) as the Internet Archive captured it on 2021-09-18. Source: html table (Internet Archive snapshot 2021-09-18)
How I read the maker's table
the live site no longer has the Razha. The table has NO size column. SIZE LABELS, FOR CARL: on the other Pinarello files the size is the CC column in cm, but on this table the CC column runs 460 to 615 and the CE column 440 to 595, and it is the CE column that carries the size names Pinarello sold this frame family in (44, 46.5, 50, 51.5, 53, 54, 55, 56, 57.5, 59.5: the Gan page, whose top tubes and angles are the same row for row, prints exactly these numbers in its CC column, and Bike Insights files the Gan under them). So size_label here is the CE column written in cm (CE 440 -> "44"); the CC values, 20 mm more on every row (460, 485, 520, 535, 550, 560, 570, 580, 595, 615), are not in the schema and are recorded here. Column mapping, from the legend printed beside the table ("CE: SEAT TUBE CENTER - END, CC: SEAT TUBE CENTER - CENTER, L: TOP TUBE CENTER - CENTER, A[deg]: SEAT TUBE ANGLE, B[deg]: HEADTUBE ANGLE, P: CHAINSTAY, T: HEADTUBE, D: BB DROP, R: FORK RAKE, G: FORK HEIGHT, REACH, STACK"): CE -> seat_tube_length (and the label); L -> top_tube_effective (drawn horizontal on Pinarello's pages); A -> seat_tube_angle; B -> head_tube_angle; P -> chainstay; T -> head_tube_length; D -> bb_drop; R -> fork_offset; G (fork height, 367 on every size) not in the schema; REACH; STACK. As printed: reach is 384 on both the 53 and the 54, and 396 on the 57.5 against 395 on the 59.5 (reach falls one size up). Close to the Gan table but not the same: stacks and reaches differ by a millimetre on most sizes, the chainstays are 410 to 412 (Gan 408 to 412) and the 53 head tube is 144 (Gan 139). STACK DATUM: not stated, null. Not printed, so null: wheelbase, standover, front centre, trail, stock stem and bar per size, stock tyre width. The one page sells the disc and the rim-brake Razha with one table: "Max Tyre Size 28mm (width as measured)" on the disc tyre line and 25mm on the rim one, axles "Pinarello Axle 12x100 & 12x142" on disc and quick release on rim, so tyre clearance, axles and brake mount are left out of frame_facts (two values each). Frame line: "TorayCa T600 UD, Internal Cable Routing, Italian BB, UCI Approved"; fork "Razha Onda Fork with ForkFlap, Tapered head tube". Category road race: the Razha sits in Pinarello's road endurance menu but its table is the Gan's race geometry. MODEL YEAR: the page prints none; 2021 is the year of the capture and the page's footer ("© 2021 - CICLI PINARELLO SRL").
