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 Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".
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 bar is than your saddle.
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 54 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.

Orome AeroEvo one-piece carbon bar/stem (sold separately, "EVO HANDLEBAR REQUIRES ADDITIONAL PAYMENT"). Spec sheet image on the bar page (https://ueeshop.ly200-cdn.com/u_file/UPAU/UPAU610/2302/17/photo/EVO1-c2ff.jpg) lists 12 combos as stem length x width c-c in drops (hoods are 10 mm narrower): 90x360, 90x380, 90x400, 100x380, 100x400, 110x380, 110x400, 110x420, 120x400, 120x420, 130x400, 130x420. The store dropdown (https://store.elvesbike.com/products/elves-falath-evo-frame-one-piece-carbon-handlebar-orome-aeroevo, format width/stem) lists 17: 360/90, 360/100, 360/110, 380/90, 380/100, 380/110, 380/120, 400/90, 400/100, 400/110, 400/120, 400/130, 420/90, 420/100, 420/110, 420/120, 420/130. Bar spec: stem angle -10 deg, reach 70 mm, drop 125 mm, stack 34 mm, flare 3 deg, 1-1/8 in steerer, 410 g (400x90). Spacers: frameset ships with three 10 mm integrated handlebar spacers (store page text); max spacer height not published. A cable-routing stem adapter for standard bars is included. Separate Orome AeroEvo stem (31.8 mm clamp, intended for AeroRay TT bars) exists but no lengths are published on its page.

How I read the maker's table
Table columns: Seat Tube, Top Tube, Reach, Stack, Standover, RC (chainstay), WB, CA (seat angle), HA, BB (drop), HT. Units mm and degrees as printed, no conversion needed. NOT IN THE 2025 TABLE (set null): front centre (diagram labels FC but table has no FC column), trail, per-size stem/bar (frameset only, bar sold separately), seat tube measurement convention (c-t vs c-c not stated), whether CA is effective or actual (diagram draws CA at the BB between a dashed seat-tube axis line and horizontal, so probably the seat-tube axis angle, uncertain). Fork offset 45 mm comes from the separate official spec sheet image (https://ueeshop.ly200-cdn.com/u_file/UPAU/UPAU610/2508/26/photo/EVO202502.jpg, saved as EVO202502.jpg), one value for all sizes; that sheet also gives steerer 300 mm, headset bearings 1-1/2 in x 7 mm upper and lower, seatpost 350 mm with 25 mm offset, max tyre 700x32c, frame weights S46 1090 g / M49 1100 / L52 1120 / XL54 1150 / 2XL56 1180 / 3XL59 1220 / 4XL61 1260 (unpainted). Headset cap/stack height not published; the AU dealer headset drawing (Feb 2023, https://cdn.shopify.com/s/files/1/0246/4323/9985/files/Falath_EVO_Headset_Feb2023_2_1024x1024.jpg) shows top 7 mm and bottom 8 mm bearings, which differs slightly from the 2025 spec sheet. ODDITIES AS PRINTED: wheelbase size 46 = 985.2 is longer than size 49 = 984.4; standover in the geometry table (768/781/802.6/817.2/831.5/853.7/873) disagrees with the EU dealer "Falath EVO+ 2025 size guide" image on eu.elvesbike.com (738/760/790/810/826/850/870, saved as eu_Screenshot2024-12-12.png) - table values used. That size guide gives rider heights: 46 158-168 cm, 49 165-173, 52 168-175, 54 170-178, 56 173-184, 59 176-186, 61 184-192. Store copy: 2025 Evo+ has "15mm longer top tube, 15mm longer wheel base, 20mm lower standover" vs the previous Evo and a T47 BB.

AU dealer also advises to "size down and use a longer stem" because the Evo has high stack and short top tube. Geometry Geeks 2025 page was fetched but its numbers came back scrambled (site obfuscation), so it was not used.
