Geometry, every size, from the maker's table

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.

In the maker's words

Kept whole, as I read it off ribblecycles.co.uk.
Ribble builds are configured at order: the page's geometry panel lists the default bar/stem per size where the model has an integrated bar (recorded in notes), otherwise the stem and bar come from the build selected (Level 1-5 or Ribble's own alloy/carbon bars); stock fields are null.

Spacer heights, top-cover height and maximum spacer stack are not published on the model page. Integrated bar defaults per size: XS 360/400 x 80, S 360/400 x 100, M 360/400 x 100, L 360/400 x 100, XL 380/420 x 120 (hood/drop width x stem length, mm).

How I read the maker's table
ODDITY AS PRINTED: front centre 518 mm on the XS against 575 on the S (with wheelbase 981 vs 975), which cannot both be right - recorded as printed and flagged; the same cell appears on the Ultra SL page. Standover and trail are not published (null). Ribble does not date its geometry (model year null); the page is the current listing on the fetch date.
