The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 54.5cm 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. 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.

Cockpit and seatpost, in the maker's words · 146 words
Two-piece bar and stem, chosen in the build configurator. The page's sizing guide, written per rider size and separate from the geometry table, reads: "X-Small | 5'2" - 5'5" - 157.5-165cm | Crank Length: 170mm | Stem: 9cm | Bar Width: 42cm | Small | 5'6" - 5'7" - 167.5-170cm | Crank Length: 170cm | Stem: 10cm | Bar Width: 42cm | Medium | 5'8" - 5'9" - 172.5-175cm | Crank Length: 172.5mm | Stem: 11cm | Bar Width: 44cm | Large | 5'10" - 5'11" - 177.5-180cm | Crank Length: 172.5mm | Stem: 12cm | Bar Width: 44cm | X Large | 6'0" - 6'4" - 182.5-193cm | Crank Length: 175mm | Stem: 12cm | Bar Width: 46cm". Because the guide is not a row of the geometry table, stock_stem_length and stock_bar_width are left null rather than paired with the table's sizes by the collector.

How I read the maker's table
the menu lists it as "ADX Rim Frameset"; "compatibility with 25mm tyres"), five sizes 50.5cm to 58.5cm. The "Sizing & Geometry" HTML table prints, by letter: A Head Angle, B Head Tube Length (mm), C Effective Top Tube Horizontal (mm), D Seat Angle, E Seat Tube Length Center To Top (mm), F Stack (mm), G Reach (mm), WB Wheel Base. Some cells print one decimal (73.0) and some none (73), recorded as printed. Not printed, so null: chainstay, BB drop, fork offset, front centre, standover, trail. Model year: not printed (null).
