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.

How I read the maker's table
the image file is named cy26 and sits in the my27 folder). The data feed carries Geometry null for every variant, so the image is the only table. The GB range also sells the Topstone CAAD 2/3 CUES 1x, the EQ, the Lefty build and a flat-bar build on the same frame; the flat-bar build is not a drop-bar bike and is not the reason for this file. SIZE LABELS: the table header prints 47.0/51.0/54.0/56.0/58.0/61.0; the shop's size selector says 47/51/54/56/58/61, which is what size_label holds. UNITS: lengths printed in centimetres to one decimal; every length here is the printed value x 10, angles as printed. The diagram draws a Q (axle to crown) but the table has no Q row. STACK DATUM: O is drawn to a horizontal through the top of the head tube where G starts. tyre_width_mm 45 is the Topstone CAAD 1's stock tyre ("WTB Vulpine TCS Light, 700x45c"), not a table number. stock_stem_length and stock_bar_width are that build's stem and bar per frame size.
