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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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 52 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 Angliru 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 "Angliru Tiagra" (https://pinarello.com/global/en/bikes/road/endurance/angliru/angliru-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 Angliru. The table has NO size column. SIZE LABELS, FOR CARL: as on the Razha page (pinarello-razha-2021.json), the CC column here runs exactly 20 mm over the CE column on every row (CC 450, 480, 510, 540, 555, 570, 590; CE 430, 460, 490, 520, 535, 550, 570); on the Razha it is the CE column that matches the size names Pinarello sold, so size_label here is the CE column written in cm (CE 430 -> "43") and the CC values are recorded in these notes, not in the schema. No other source names the Angliru's sizes (Bike Insights does not list the model), so this labelling is a reading of the table, not a printed label. 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 (47 on every size); G (fork height, 373 on every size) not in the schema; REACH; STACK. As printed: reach 370 on the 49 and 371 on the 52 (a 1 mm step against 12 to 13 mm steps either side), with the stack rising 28 mm there. 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 Angliru 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 "Angliru Onda Fork with ForkFlap, Tapered head tube". MODEL YEAR: the page prints none; 2021 is the year of the capture and the page's footer ("© 2021 - CICLI PINARELLO SRL").
