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.

In the maker's words

Kept whole, as I read it off cube.eu.
TIME TRIAL COCKPIT, not a drop bar: "CUBE Aerium C:68X Cockpit System, XS-S LOW, M-L HIGH"; the Ergonomics table prints Stem length 81, Angle stem -18 deg and Handlebar width 400 on every size (stock_stem_length and stock_bar_width carry them).

How I read the maker's table
Collected on the coordinator's instruction under the brief's time trial rule, with the BB figure kept as printed. SIGN OF THE BB FIGURE, FOR CARL: row H prints -78 on every size, while every other Cube table read in this round (Agree, Attain, Litening, Nuroad, Cross Race) prints the same row as a positive drop (63 to 74). bb_drop holds -78 exactly as printed; read with the other Cube tables' sign it would mean the bottom bracket sits 78 mm ABOVE the axles, which no road frame does, so the minus is almost certainly the maker's sign convention slipping on this one table and the frame's drop is 78 mm. Not changed: Carl decides. The Aerium C:68 TT frameset (https://www.cube.eu/cube-aerium-c-68x-tt-frameset-carbon-n-prism/131110, UCI approved, fetched 2026-10-20) prints a different table (chainstay 408, wheelbase 977/990/1013/1041, standover 782/798/818/840, reach 396 on XS, stack 498/518/540 on S to L) with the same -78; it is not covered by this file. Stock tyre "Continental Grand Prix 5000 TT TR, Kevlar, 28-622" (tyre_width_mm 28); "Width tire maximum 30". Headset "Acros Integrated, Top 1 1/8", Bottom 1 1/4""; frame "Aerium C:68X Monocoque Advanced Twin Mold Technology, Twin Head Tube, Full Internal Cable Routing, Flat Mount Disc, 12x142mm, AXH". CROSS-CHECK NOTE: the 4 differing cells are this sign only: Bike Insights (Aerium 2025 base, citing a cube.eu Aerium C:68X page) holds +78 where the maker prints -78; every other compared cell agrees.
