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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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
Look prints decimals with both commas and points (486,2 and 525.2) in one row; converted by script, numbers unchanged. No stack datum is stated in words (stack_datum null). Frame "LOOK 795 BLADE 2 RS disc"; table heading "795 blade rs frameset", "Wheels diameter : 682 mm". model_year 2023 from the product slug ("795-blade-rs-2023-frameset") and the drawing's folder (products-bikes-2023); the page sits under Blade RS 2 beside the current Blade RS 3. MAKER DISCREPANCY: the XL head tube prints 198,5 here and 189,5 on the Blade RS 3 page, whose table is otherwise identical; the table's own stack steps point to about 187, so 198,5 reads as a transposition of 189,5; kept as printed, listed for Carl. No Standover row on this page. Rows kept here only: L - Fourche 368 on every size. "COMPATIBLE WITH TIRES WITH A MAXIMUM SIZE OF 32 mm (DISC BRAKE VERSION ONLY)". Frameset only: no stock tyre (tyre_width_mm null). stock_stem_length and stock_bar_width are the frameset spec's Combo Aero sizes per frame size. CROSS-CHECK NOTE: Bike Insights files this table under version 2025 (its 2023 version holds the first-generation 795 Blade RS numbers, stack 505 on XS); against 2025 it differs on chainstay (415 there, 410 on every size here) and on the XL head tube (189.5 there, citing Look Iconic Edition frameset page, against 198,5 here), which supports the transposition reading above.
