Geometry, every size, from Bike Insights
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.

Notes on the cockpit
Kept whole, as I read it off bikeinsights.com.Not recorded for the drop-bar builds: the only complete Bike Insights build for 2022 is the flat-bar "20 Flat Bar", whose stem and bar are not the drop-bar bike's; no bar is named.

SECOND-HAND NUMBERS, NOT CHECKED AGAINST THE MAKER: Bike Insights' record of the Genesis Croix de Fer, version "2022", build "20 Flat Bar" (disc, steel frame, drop bar on Bike Insights), 5 sizes XS, S, M, L, XL. Source: aggregator (Bike Insights): version "2022", build "20 Flat Bar", numbers read from the page's __NEXT_DATA__ data script; the maker serves its site only through scripts and this generation has been replaced
How I read Bike Insights' table
Genesis serves its own site only through scripts (every page returns the same empty shell with the data fetched by script), so even the current table cannot be read, and Tredz and Sigma Sports list no Genesis bikes. This is the previous generation: Bike Insights files a newer, different geometry (2024, 2025 and 2026 versions with sizes XS/SM/MD/LG/XL, stack 552 to 623) for the current bike, so this table is no longer the maker's and Bike Insights is the source of last resort (D4 second amendment). Bike Insights cites as its source: https://www.genesisbikes.co.uk/genesis-croix-de-fer-20-flat-bar-vargn21030. Field mapping from Bike Insights: stack, reach, head_tube_angle, seat_tube_angle (from its seat_tube_angle field), head_tube_length, top_tube_effective (from effective_top_tube_length_center_center), seat_tube_length (from seat_tube_length_center_st_top, the first of centre-to-top, centre-to-top-tube, centre-to-centre that it holds), chainstay_length, wheelbase, bottom_bracket_drop, fork offset, front_center, and from its base build the standover height, stem length and handlebar width (a width recorded in cm is converted to mm). Bike Insights stores no published trail (only its own computed one), so trail is null. Its base build lists a 622 mm rim and a 40 mm tyre. Bike Insights' 2020 and 2021 versions match this 2022 record on every compared cell. Its 2016 version (source: Genesis catalogues) has the same stack and reach but a BB drop of 69/69/66/66/63 against 73 here; its 2017 version (source: an Evans-hosted 2017 geometry chart PDF) differs by 10 mm of head tube and 1-2 mm of stack on M to XL; its 2015 and 2011-2014 versions cite Geometry Geeks and were not used. The only complete build Bike Insights holds for 2022 is "20 Flat Bar" (its drop-bar "40" build has the XL only, partly filled; "50" was not fetched); the frame numbers are the frame's whichever bar is fitted, but the build's stem length and bar width belong to the flat-bar bike, so stock_stem_length and stock_bar_width are left null.
