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) |
|---|---|---|---|---|---|---|---|---|
| XS (460) | 509 | 366 | 70.7 | 74.9 | 108 | 407 | 971 | 725 |
| S (480) | 520 | 372 | 71.3 | 74.4 | 118 | 407 | 976 | 741 |
| M (500) | 536 | 382 | 72 | 74 | 130 | 407 | 980 | 759 |
| L (530) | 556 | 389 | 72.3 | 73.5 | 150 | 407 | 991 | 784 |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The M (500) 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.

How I read the maker's table
the page HTML has no text geometry table. Table headers as printed: A Seat Tube Length, B Stack, C Reach, D Top Tube Length, E Head Tube Length, F Wheelbase, G Chainstay Length, H BB Drop, I BB Height (271 all sizes), J Seat Tube Angle, K Head Tube Angle, L Fork Length (371 all sizes), M Fork Rake, N Trail(32C), O Seatpost Length (320/320/360/360/360), P Seatpost Setback (0/0/15/15/15), Standover Height, Tire (700C*32 all), STR (1.391/1.398/1.403/1.429/1.456), Rider height (XS 155-163 cm, S 163-171, M 171-179, L 179-186, XL 186-193). All lengths in mm, angles in degrees, no conversion needed. Winspace size labels: XS(460), S(480), M(500), L(530), XL(550); the number is the seat tube length. Top tube: Winspace labels it only "Top Tube Length"; in the diagram D is drawn as a horizontal line from the head tube top to the seat tube axis, so it appears to be the effective/horizontal top tube (uncertain, not stated). Trail is published for a 32C tyre only. Front centre NOT published (null). Stock stem length / bar width per size NOT published: Winspace lets the buyer choose the cockpit size on complete bikes (FAQ on the 105 Di2 page: "only crank length and handlebar size are available for selection"; EU/US warehouse pre-assembled bikes have limited or no choice), so per-size stock values are null. Max spacer height / headset cap height NOT published (unknown). Other official specs (brochure page 2 + complete-bike spec text): head tube 1-1/2 in / 1-1/2 in "FSA ACR system"; headset "Integrated, 51.8mm/40mm (45x36 deg)" (Ultegra page: "51.8 x 40 x 8 x 45 deg x 36 deg"); fork full carbon 1-1/8 in (28.6 mm OD1) steerer, 51.8 mm crown race; BB86 press-fit 86.5 mm; round 27.2 mm seatpost; flat-mount disc; 12 mm thru-axles F119 / R163; max tyre 700x32C; frame 699 g size M unpainted. Integrated cockpit: yes on complete bikes (Zero SL), frameset sold without a bar; full internal routing through the bar. Model year is not stated anywhere by Winspace. SECONDARY CROSS-CHECK: Bike Insights (https://bikeinsights.com/bikes/66ca192dccd3eb001a3b1ac8-winspace-cycle-co-slc3?version=2024&build=frameset, labelled 2024, cites winspace.cc) reprints identical stack/reach/HTA/STA/HT/TT/ST/chainstay/wheelbase/BB drop/rake/standover values; its trail (68.2/64.4/64.1/62.2/60.3) and front centre (575/579.9/583.9/594.8/609.7) are its own calculations and differ from / are absent in the official table, so they are NOT used here.
