The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 55.5cm 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.

How I read Bike Insights' table
Kinesis UK's own store (kinesisbikes.co.uk, its framesets and bikes collections 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 kinesis-4s.json. Bike Insights cites as its source: https://www.kinesisbikes.co.uk/Catalogue/Models/Racelight/4S-DISC. 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_ht_top), 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 28 mm tyre.
