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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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 table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
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.

Complete Gen 5 bikes ship with Cannondale's one-piece SystemBar Road; the frame takes Cannondale's Delta steerer ("1-1/8" to 1-1/4" Delta steerer") and both SystemBars route "electronic shifting only". The LAB71 frameset page sells two of them beside the frame. (1) SystemBar Road (https://www.cannondale.com/en-gb/gear/components/handlebars/carbon-handlebars/systembar-road-carbon-handlebar): one-piece carbon bar/stem; bar reach 80 mm; drop 130 mm; flare 40 mm (printed in mm); stem angle -6 deg; stem lengths 90/100/110/120/130/140/150 mm; widths 340/360/380 mm (sizes 340x90, 340x100, 360x100 to 360x150, 380x100 to 380x120); 375 g. On the SuperSix EVO 1 SMU it is specified as "90x340mm (44-52cm), 100x360mm (54-56cm), 110x380mm (58-61cm)". (2) SystemBar Road SL (https://www.cannondale.com/en-gb/gear/components/handlebars/carbon-handlebars/systembar-road-sl-carbon-handlebar): lighter one-piece carbon bar/stem; bar reach 80 mm; drop 130 mm; flare 40 mm; stem angle -6 deg; stem lengths 90/100/110/120/130 mm; widths 380/400 mm (sizes 380x90 to 380x110, 400x100 to 400x130); 265 g. Seatpost: Cannondale C1 Aero 40 Carbon V2, 365 mm, "0mm offset (44-54cm), 15mm offset (56-61cm)" (frameset and SuperSix EVO 1 SMU specs).

How I read the maker's table
The geometry section of the LAB71 frameset page (SalsifyId 1015-COLL2026), the Hi-MOD frameset page (7642-COLL2026) and the SuperSix EVO 1 SMU page (0548-COLL2026-SMU) all show the same image, c26_supersixevo_geotable, headed "SuperSix EVO Gen 5.", so this one file covers the LAB71 (Series 0 carbon) and the Hi-MOD frames: one geometry table. The site's product data feed (/en-gb/api/products/<id>) carries Geometry null for every variant, so the image is the only table. The page says of Gen 5: "Compared to Gen 4, we've lowered the stack by 10 mm across all sizes and replaced the former size 51 with new 50 and 52 options". UNITS: the table prints lengths in centimetres to one decimal (49.5); every length here is the printed value x 10 (495 mm), angles as printed. Wheel Size row: 700c. STACK DATUM: O is drawn from the bottom bracket centre up to a horizontal through the top of the head tube, where G starts; no headset cover is drawn. Sizes 56, 58 and 61 take a 73.0 deg head angle and a 45 mm rake fork (the frameset spec: "55mm offset (44-54cm), 45mm offset (56-61cm)"), so the 56's wheelbase (99.5) and front centre (59.5) are shorter than the 54's (101.0, 61.1); checked against the table's own numbers (front centre and chainstay against wheelbase, and stack, reach, head angle and rake against front centre) and consistent, so it is as designed, not a misprint. Trail is printed to 1 mm (6.0/5.8 cm); the tyre it assumes is not stated. tyre_width_mm 29 is the stock tyre of the SuperSix EVO 1 SMU ("Vittoria Corsa Pro, 700x29c"), not a table number. stock_stem_length and stock_bar_width are the SuperSix EVO 1 SMU's SystemBar Road sizes per frame size (90x340mm 44-52, 100x360mm 54-56, 110x380mm 58-61); other builds may differ, and the frameset ships without a bar. posts: the C1 Aero 40 Carbon V2 seatpost offsets the frameset spec lists per size (0 mm 44-54, 15 mm 56-61). Model year 2026 from the product data feed (ModelYear "2026"). Category from the maker's menu (Road > Race).
