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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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

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 M 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.
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 page's hidden data (GEOMETRY_DEFAULT) holds an older or partial table: sizes S, M, L, XL; it differs from the drawing in 27 cells: S T1: chart 517, page data 540; S H/T: chart 115, page data 133; S A: chart 69, page data 68; S B: chart 76, page data 74; S F: chart 629, page data 642; S WB: chart 1070, page data 1083; S STACK: chart 608, page data 620; S REACH: chart 365, page data 362; M T1: chart 541, page data 570; M H/T: chart 140, page data 153; M B: chart 75,5, page data 73.5; M F: chart 651, page data 657; M WB: chart 1092, page data 1098; M STACK: chart 630, page data 644; M REACH: chart 378, page data 379; L T1: chart 563, page data 600; L H/T: chart 155, page data 173; L B: chart 75, page data 73; L F: chart 668, page data 682; L WB: chart 1109, page data 1123; L STACK: chart 646, page data 663; L REACH: chart 390, page data 397; XL T1: chart 598, page data 620; XL H/T: chart 180, page data 193; XL B: chart 74,5, page data 72.5; XL STACK: chart 669, page data 682; XL REACH: chart 410, page data 405. Size labels as the source prints them. R (fork offset) is printed "45/50" on every size (two offsets), so fork_offset is null and both are named here. Not published, so null: fork offset, standover, trail, stock stem length, stock bar width. Model year not printed (null).
