Geometry, every size, from the maker's table

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The ML 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.

Two-piece cockpit: Giant Contact SLR Aerolight stem (-10 deg, 31.8 mm bar clamp, D-shaped OverDrive Aero 1 1/4 in steerer clamp, stack height 44 mm, 123 g at 100 mm) + Giant Contact SLR carbon handlebar. Stem lengths per official stem page spec line: 70/80/90/100/110/120/130/140 mm (the same page's feature text says "eight lengths from 80mm to 140mm" - the page is internally inconsistent about 70 mm) - https://www.giant-bicycles.com/us/contact-slr-aerolight-stem--10--2024. Contact SLR handlebar (2025) widths drop-to-drop 360/380/400/420/440 mm, hood-to-hood 340/360/370/390/410 mm, drop 125 mm (120 mm for 360/380), reach 72 mm (68 mm for 360/380), flare 11 deg for 400/420/440 (8 deg for 360/380), 165 g at 420 mm - https://www.giant-bicycles.com/gb/contact-slr-handlebar--2025-. Stock combos per size (geometry table row O/N plus the SL 0 Red spec): XS 80 mm x 37/40 cm, S 90 x 37/40, M 100 x 39/42, M/L 110 x 39/42, L 110 x 41/44, XL 120 x 41/44 (hood/drop widths). Spacers: D-shaped OverDrive Aero spacers; individual spacer heights, max spacer stack and top cap height are NOT published on any Giant page I could read - unknown.

How I read the maker's table
the identical table appears on https://www.giant-bicycles.com/ca/tcr-advanced-sl-0-da-2025 and https://www.giant-bicycles.com/us/tcr-advanced-sl-0-red-2025. Page states model year MY25 (2025); Giant showcase page calls it the 10th generation TCR (https://www.giant-bicycles.com/global/showcase/tcr-advanced-sl). Sizes XS, S, M, M/L (labelled ML in the table), L, XL. Rider height guide on the same page: XS 157-169 cm, S 165-175, M 171-181, ML 177-187, L 183-193, XL 189-199. Giant rows: A seat tube length, B seat tube angle, C top tube length, D head tube length, E head tube angle, F fork rake, G trail, H wheelbase, I chain stay, J BB drop, K stack, L reach, M standover, N handlebar width, O stem length, P crank length, Q wheel size (700C). SEAT TUBE ANGLE: Giant does not say effective or actual; the diagram (https://static.giant-bicycles.com/Images/Giant/GlobalFrames/giant-onroad-geo.png) draws angle B at the BB between the seat tube line and horizontal. Top tube row is labelled "Top Tube Length"; Giant does not say horizontal/effective, but the diagram draws C as a horizontal line from the head tube to the seatpost axis, so it is treated as effective (uncertain). FRONT CENTRE: not published - null. STANDOVER, TRAIL, BB DROP: published, values above. COCKPIT: Giant markets an "integrated cockpit" (OverDrive Aero D-shaped steerer, internal routing, integrated top cap/spacers) but the stem (Contact SLR Aerolight, -10 deg) and bar (Contact SLR, 11 deg flare) are separate parts, so integrated_cockpit=false (two-piece, swappable). Handlebar width row N in the geometry table is the drop-to-drop width (400/400/420/420/440/440); the SL 0 Red spec line gives hood/drop widths XS 37/40, S 37/40, M 39/42, M/L 39/42, L 41/44, XL 41/44 cm. stock_bar_width uses the geometry-table (drop) figure. SPACERS / TOP CAP: no Giant page I could read publishes OverDrive Aero spacer heights, max spacer stack or top cap height - unknown; a forum search snippet mentions 5 mm and 10 mm "transition" spacers but I could not read the thread (Weight Weenies returned 403) so treat as unverified. SEATPOST: integrated seatpost (ISP, cut to length); clamp offset -5/+15 mm, standard and long clamp versions (frameset page); ISP adjustment range not published. Crank lengths (2025): 170/170/172.5/172.5/175/175. Max tyre 33 mm (SL 0 Red extras). SL 0 DA build (CA) lists only sizes S, M, M/L, L; frameset and SL 0 Red list XS-XL; availability varies by country. MY2026 NOTE: the current frameset page https://www.giant-bicycles.com/us/tcr-advanced-sl-frameset (titled 2026) keeps identical stack, reach, angles, HT, TT, CS, wheelbase and stem lengths but changes trail (72.1/64/59.2/59.2/59.2/59.2), BB drop S and M (70 vs 69.5), standover (719/734/752/768/786/803), stock bar widths (420/420/440/440/440/440) and crank lengths (165/165/170/170/172.5/172.5) - the values returned here are the 2025 table. Units: all mm and degrees as published (Giant also lists inches; mm taken directly, no conversion). SAME NUMBERS AS THE 2022 TABLE, CHECKED 2026-08-29: this page and the 2022 TCR Advanced Pro Disc page were read again from giant-bicycles.com on 29 August 2026 and each matches its own file cell for cell, so the repetition is Giant's and not a copied file. Giant publishes the same stack, reach, head angle, head tube, top tube, seat angle, chainstay, wheelbase, fork rake, bar width and stem length for the 9th and 10th generation TCR in every size; the two tables differ only in seat tube length (this table prints the integrated seatpost height, 680 to 830 mm, against the 2022 frame's 425 to 560 mm seat tube), standover (703/722/743/771/798/822 here against 706/725/747/773/800/816), bottom bracket drop on S and M (69.5 here against 70) and the rounding of trail (72/59 here against 72.1/59.2).
