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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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

In the maker's words
Kept whole, as I read it off vitusbikes.com.Two-piece: "Prime Primavera Carbon Aero UD Carbon" handlebar (the spec prints "Rise: 78mm", which reads as the bar's reach) on a "Prime 3D forged, Bar Bore 31.8mm, +/- 5 degrees" stem; the 2026 spec gives no per-size lengths or widths, but the geometry chart's Stem length row prints 90/100/110/110/120/120 mm and its Handlebar Width row 380/400/420/420/440/440 mm (XS to XXL).

How I read the maker's table
footer "2026 Vitus"). Product page for the Vitesse EVO Force AXS Road Bike 2026, six chart sizes XS to XXL (the page's size selector offers S, M, L, XL for this build). Vitus prints no trail (null) and does not say where stack is measured to, so stack_datum is null. Units ("mm", "°") were stripped by the parser. The same chart, cell for cell, sits on Vitus's older Vitesse EVO CRS Ultegra product page (Ultegra R8000 build, also checked on 2026-10-20), so the frame is unchanged since that build. Fork rake 51 mm on XS and S, 45 mm from M up (size-specific fork), which is why the M front centre (591) and wheelbase (991) sit 1 mm under the S. Max tyre 700 x 30c; the page says up to 32c depending on rim and tyre. Seatpost 27.2 x 300/300/350/350/400/400 mm.
