Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.| Size | Stack (mm) | Reach (mm) | Head angle (deg) | Seat angle (deg) | Head tube (mm) | Chainstay (mm) | Wheelbase (mm) | Standover (mm) |

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.
In the maker's words
Kept whole, as I read it off winspace.cc.Winspace sells its frames bar-less or as "bundles" with its own one-piece bars (HYPER Integrated Handlebar, Zero K, Zero SL, HYPER 2 Riser; Adventure Integrated Handlebar for the gravel frames); the frame page lists no per-size stock bar or stem, so stock_stem_length / stock_bar_width are null.

How I read the maker's table
every number was read from the image by the collector. The stack, top tube, wheelbase and trail rows are printed to two decimals (e.g. stack 504.72, wheelbase 969.11, trail 64.97) and are recorded exactly so; BB Height 271 all sizes; Fork Length 370 all sizes; seatpost 320/320/360/360/360 with setback 0/0/15/15/15; STR 1.39/1.40/1.40/1.44/1.48; no height row on this table (the separate "Winspace Road Height Guide" image was not read). Front centre not published (null). ODDITY AS PRINTED: trail falls to 60.26 on S then rises to 63.28 on M because the rake drops from 50 to 44 mm at M (as on the T1600 and SLC5). Consistency check (mine, not published): with a 350 mm wheel radius the printed head angles and rakes give trail 62.1 / 57.8 / 61.4 / 58.6 / 56.4, i.e. 2.4 to 2.9 mm LESS than the printed Trail(32C) row on every size, which would need a wheel radius of about 358 mm; the maker's basis is not stated beyond "32C", so the row is kept as printed and this is only noted. MODEL YEAR: not stated (Shopify product published 2025-01-02; the previous T1550 generation is a different frame and is not in this file); null. Category aero road (the page: "Born to race ... retains the aggressive geometry"; T-series aero frame). No aggregator consulted.
