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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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

How I read the maker's table
Product page "Razor Womens Road Bike Claris" (rim brake), tagged "Model Year: 2020" and "Geometry Page: razor-womens-geometry"; the 2020 "Razor Womens Disc Road Bike Claris" page prints the same table, so this file is the 2020 women's Razor frame in both brake versions. Four sizes XS to L (the table header carries two empty columns, ignored). It is not the 2020 Razor table (vitus-razor-2020): its M and L stack and reach (511.2/373, 537.2/384) are the Razor XS and S, with its own head tubes (100 to 137) and seat tubes. The later Razor W (2022 page) prints the 2021 Razor table plus an XXS instead. Standover and trail not printed (null); stack datum not stated. POSSIBLE MAKER SLIP, kept as printed: the Virtual TT row (510/535/545/555) is the Razor XS to L row, and it does not close with this table's own stack, reach and seat angle (S: 368 + 503.8 / tan 75 = 503.0 against 535 printed); seat_angle_check shows it. Stems: table 80/80/90/90, specification list XS:70 S:80 M:90 (flagged, table recorded).
