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.
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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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.
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.
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.

Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 53 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.

In the maker's words
Kept whole, as I read it off pinarello.com, from the Internet Archive's copy of 2021.The Nytro Road Ultegra build ships with the handlebar "Jaguar XA Aero Di2" and the stem "Tiger Alu Aero Di2" (the page's COCKPIT section).
Cockpit and seatpost, in the maker's words · 52 words
The Nytro Road Ultegra build ships with the handlebar "Jaguar XA Aero Di2" and the stem "Tiger Alu Aero Di2" (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 "Nytro Road Ultegra" (https://pinarello.com/global/en/bikes/road/supercharged/nytro-road/nytro-road-ultegra) as the Internet Archive captured it on 2021-09-18: the first Nytro e-road bike (Fazua Evation Ride 50 motor, 250 Wh battery, TorayCa T700 frame), which the TQ-motored Nytro E Road (pinarello-nytro-e-road.json) replaced.

How I read the maker's table
the live site no longer has it. The table has NO size column: size_label is the CC column written in cm (CC 465 -> "46.5"), as in the other Pinarello files. 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; L -> top_tube_effective; A -> seat_tube_angle; B -> head_tube_angle; T -> head_tube_length; D -> bb_drop; R -> fork_offset (50 on every size); G (fork height, 370) not in the schema; REACH; STACK. TWO SLIPS ON THE MAKER'S TABLE, FOR CARL: (1) the P column, labelled chainstay, prints 582, 582, 591, 600 and 615 mm, which no road chainstay is (they rise with the size, as a front centre would); chainstay is therefore null on every size and the printed P values are kept here. (2) The 46.5 and 50 rows are the same in every column but CE and CC (L 525, A 74, B 71.4, T 130, D 72, reach 370, stack 531), so one of them was probably copied over the other; both are recorded as printed, which leaves stack and reach flat from the 46.5 to the 50. STACK DATUM: not stated, null. Not printed, so null: wheelbase, standover, front centre, trail, stock stem and bar per size, stock tyre width ("Pirelli P7 black 60 tpi Nylon breaker, Max Tyre Size 28mm (width as measured)"). MODEL YEAR: the page prints none; 2021 is the year of the capture and the page's footer ("© 2021 - CICLI PINARELLO SRL").
