These numbers are second-hand, from Bike Insights. I have not checked them against the maker's own table. Bike Insights cites planetx.co.uk.

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 L/520mm 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.

SECOND-HAND NUMBERS, NOT CHECKED AGAINST THE MAKER: Bike Insights' record of the Planet X Kaffenback, version "2022", build "SRAM Rival 1 x 11" (disc, steel frame, drop bar on Bike Insights), 4 sizes S/480mm, M/500mm, L/520mm, XL/540mm. Source: aggregator (Bike Insights): version "2022", build "SRAM Rival 1 x 11", numbers read from the page's __NEXT_DATA__ data script; the maker no longer publishes this table
How I read Bike Insights' table
Planet X's own site (planetx.co.uk, its current range read on 2026-10-21) no longer carries this generation's table, so Bike Insights is the source of last resort (D4 second amendment). The current generation, from the maker, is planet-x-ec-130.json, planet-x-london-road.json, planet-x-pro-carbon-xv.json, planet-x-reiver.json, planet-x-tempest.json. Bike Insights cites as its source: https://www.planetx.co.uk/i/q/CBPXKBAPEX1/planet-x-kaffenback-sram-apex-1-bike. 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 32 mm tyre.
