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.
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.
