The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 56 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. A dashed tube is a number the maker left out (est.).
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 the maker's table
model_year taken from it), six sizes 48, 51, 54, 56, 58, 61. The P-Series before the current one (cervelo-p-series.json, 44 cells differ). Cervelo's row labels on this triathlon page: Reach, Stack, Head Tube Angle, Front Center (front_centre), Bottom Bracket Drop, Head Tube Length, Standover Height, Trail (printed, kept), Wheel Size, Fork Offset, Wheelbase, Chainstay Length, "Effective Top Tube @75 Deg Seat Tube" and "Effective Top Tube @79 Deg Seat Tube". Cervelo does not publish a seat tube length (null). Cervelo does not state the stack datum (null). The 12 cells that differ from Bike Insights are this choice: its 2022 P-Series entry records the 75 degree position (seat angle 75 and the @75 top tube) on all six sizes; every other compared cell agrees.
