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 Most makers do not publish it, so I assume 15 mm and add 6 mm to the band, which on its own is enough to hold an answer at "probably" rather than "fits".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

How I read the maker's table
Primary table: https://www.canyon.com/en-gb/productpdf/geometry/?pid=4069 (Ultimate CFR Di2, en-gb, JSON-LD 'Year':'2026' on the product page https://www.canyon.com/en-gb/road-bikes/race-bikes/ultimate/cfr/ultimate-cfr-di2/4069.html). Cross-checked identical frame rows on: CF SLX 8 Di2 pid 4372 (product page Year 2027) https://www.canyon.com/en-gb/productpdf/geometry/?pid=4372 ; CF SLX 7 Di2 pid 4370 ; CF SLX 8 AXS pid 4371 and pid 4067 ; CFR AXS pid 4071 ; CFR Frameset pid 3860 ; CFR LTD pid 3863 (Year 2025, CP0018 cockpit) ; DE page pid 4066. Only difference between CFR and CF SLX pages: 2XL top tube 610 (CFR pages) vs 609 (CF SLX pages). Canyon row labels: Seat Tube Length (b), Top Tube Length (c), Head Tube Length (d), Head Tube Angle (e), Seat Tube Angle (f), Chainstay Length (g), Wheel Base (h), Stack (i), Reach (j), Stand-over Height (k), Bottom Bracket Offset (l) = BB drop. UNITS: all mm and degrees as published; decimal commas converted to points (73,25 -> 73.25). NOT PUBLISHED BY CANYON (set null): fork offset/rake, trail, front centre, whether the seat tube angle is effective or actual (Canyon just says 'Seat Tube Angle'), and a single stock bar width (Canyon publishes an adjustment range 390-440 mm per size for the PACE bar, so stock_bar_width is null; the CP0018-era value was 390 mm for 3XS-S and 410 mm for M-2XL). Secondary, unverified: Escape Collective review (https://escapecollective.com/the-prince-and-the-pauper-2023-canyon-ultimate-cf-sl-7-vs-ultimate-cfr-review/) says trail is 'less than 59 mm for a medium' and 'bottom bracket drop ... 73 mm for the 700c-equipped sizes (the 3XS and 2XS sizes use smaller 650b wheels)' - MY2023 statement; a search-engine summary claimed a 41.5 mm fork offset but I could not find that figure in the article text, treat as UNVERIFIED. SIZES: current CFR and CF SLX en-gb pages list 2XS-2XL (7 sizes). 3XS exists for CF SLX (not CFR) per BikeRadar 2023 launch article https://www.bikeradar.com/news/2023-canyon-ultimate ('eight frame sizes (seven for the CFR, which drops the 3XS size)', 'SLX frame only gets 650b wheels in the 3XS size'); the 3XS row I include comes from the older US CF SLX 8 Di2 geometry page https://www.canyon.com/en-us/productpdf/geometry/?pid=3320 (no model year shown; CP0018 era) and is labelled as such. GEOMETRY CHANGED BETWEEN TABLES (important for the app): older CP0018-era tables (US pid 3320 CF SLX 8 Di2, US pid 3325 CFR Di2) show 2XS with HTA 71.5, chainstay 405, wheelbase 965 (pid 3325) or 975 (pid 3320), BB drop 60, wheel size 27.5in, and M HTA 73.3; the current tables (and already the MY2025 CFR LTD pid 3863) show 2XS with HTA 70, chainstay 410, wheelbase 975, BB drop 73, 28in wheels, and M HTA 73.25. Which model year the 2XS switch to 700c happened is uncertain (between MY2023 and MY2025). Also the US pid 3320 page lists seat tube angle 73.9 for 2XS-XL (73.5 for 3XS and 2XL) whereas every other page lists 73.5 for all sizes - treat 73.9 as an anomaly/uncertain. EXTRA ROWS USEFUL FOR CONTACT-POINT MODELLING: Canyon 'Effective Stack (o)' / 'Effective Reach (p)' = BB to hand position on the hoods including the shipped headset spacers (per https://www.canyon.com/en-us/road-bikes/pace-bar/).
