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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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

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.

How I read the maker's table
The table has NO size column: Pinarello names a frame size by its seat tube centre-to-centre length in cm (the Dogma F page's weight line reads "Weight in size 53"; the CC column prints 530 on that row), so size_label is the CC column written in cm (CC 430 -> "43", 465 -> "46.5"); nothing else is derived. Column mapping: CE (seat tube centre to end) -> seat_tube_length; CC (centre to centre) -> size label; L -> top_tube_effective; A -> seat_tube_angle; B -> head_tube_angle; P -> chainstay; T -> head_tube_length; D -> bb_drop; R (fork rake) -> fork_offset; G (fork height, axle to crown) not in the schema; REACH -> reach; STACK -> stack. The legend beside the table reads "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". TOP TUBE: the drawing beside the table draws L horizontal at head tube top height from the seat tube line to the head tube line, so L is recorded as top_tube_effective. STACK DATUM: the drawing (read only for its letters and datums, not stored) takes STACK from the bottom bracket centre up to a horizontal line at the top of the head tube under the stem, and REACH to the same point; no words say whether a headset cover is included, so stack_datum is null. Not published, so null: wheelbase, front centre, trail, standover, stock stem and bar per size. Model year is not printed on the page (null). The previous X1 and X3 pages print this identical table (P chainstay 415, G 373, T 2 mm longer than the X5/X7/X9 table; stack, reach and angles the same). Stock tyre "Pirelli P7 26-622" (tyre_width_mm 26). model_year 2023 is the first Bike Insights version of this table ("X" 2023, sourced from this X1 page); the X1 and X3 predate the 2023 X5/X7/X9 launch and the maker prints no year.
