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 Most makers do not publish it, so I assume 10 mm and add 6 mm to the band beside every answer.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

Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
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.
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Generic stem and barAssumedNo bar is listed for this frame.

How I read the maker's table
The frame is no longer on Winspace's live store (its product sitemap, fetched 22 Oct 2026, lists no SLC2); the archive holds the Shopify page from Apr 2025 to Mar 2026 and the older WordPress page (https://www.winspace.cc/product/slc2-frameset/) from Nov 2022, so the frame was on sale from at least 2022 to early 2026; model_year 2025 is the year of the capture used. The page sells it in rim brake (USD 1480) and disc brake (USD 1580) versions; one table covers both. TABLE (the first description image, a letter drawing over a table, XS/S/M/L/XL): A Seat Tube Length, B Stack (drawn vertically from the BB centre to the head tube top), C Reach (horizontal to the head tube top), D Top Tube Length (drawn horizontal, recorded as top_tube_effective), E Head Tube Length, F Wheelbase, G Chainstay Length, H BB Drop, I BB Height 269 every size (not in the schema), J Seat Tube Angle, K Head Tube Angle, L Fork Length 366 every size (not in the schema), M Fork Rake, N Trail (maker-published, kept; no tyre named), O Seatpost Length 300 and P Seatpost Setback 0 every size (the post supplied; not in the schema, and not recorded as posts because the frame takes any 27.2 mm round post), and a last row "O. Standover Height" (lettered O a second time; the drawing's letter for standover is Q: a label slip, numbers kept). SECOND TABLE ON THE SAME PAGE, NOT USED FOR sizes: the 15th description image (https://cdn.shopify.com/s/files/1/0912/6101/0215/files/15_9d2e2f96-bfe0-435d-aed4-4cde81463e96.jpg?v=1753347259, 1000x300 px, an older brochure strip in Winspace's earlier style, "Sizes: 450/470/490/520/550/580mm, Weight: 780g+/-30g (470mm), Bottom Bracket: Pressfit BB86, Group Set: Mechanical, Di2, EPS, Included: FSA Headset, Original Carbon Seatpost") prints six sizes, read by eye: size 450/470/490/520/550/580; A seat tube 450/470/490/520/550/580; B top tube 505/520/535/550/575/595; C head tube 100/115/130/150/175/200; D chainstay 406/406/406/406/410/410; E head angle 70.5/71.5/72/72.5/73/73; F seat angle 75/74.5/74/73.5/73/72.5; G BB drop 70; H front centre 575/578/584/595/605/619; I fork length 370; J wheelbase 971/973/980/991/1005/1019; K rake 45; reach 372/378/383/392/399/406; stack 495/513/529/550/575/599 (its drawing labels reach "RECAH"). The two tables differ by 1 mm in stack and head tube on most sizes, chainstay 408 against 406, wheelbase by up to 3 mm, and L reach 387 against 392; the first table is the one used because it is the page's main chart and closes on every size (L: 387 + 549 / tan 73.5 = 549.6 against the printed 550), where the strip's L reach 392 misses its own top tube by 5 mm (392 + 550 / tan 73.5 = 554.9 against 550). The strip also has a 580 size the main chart does not. Bike Insights' SLC 2.0 (2021) holds the strip's numbers (see cross_check); listed for Carl. The page's text says "Sizes: Seat Tube 440/470/490/520/550/580mm" (440 where both tables print 450).
