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. 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.

Notes on the source
SECOND-HAND NUMBERS: copied from Bike Insights (https://bikeinsights.com/bikes/5ee24ea69fbe2900175bd569-argon-18-gallium?version=2020&build=base), not read off the maker's own table. Source: aggregator (Bike Insights)
How I read Bike Insights' table
Bike Insights cites the maker's page: https://www.racycles.com/final-sale/frames/argon-18-gallium-disc-frameset-17184. The maker no longer publishes this table, so these numbers have not been checked against it; the seed stores this version as an aggregator source and caps its band (D17, D4 second amendment). Build: Base. Bike Insights files it as Road Bike / Paved Road Bike / Performance Road. Where it measures differently: top_tube_effective is its effective_top_tube_length_unknown. Trail is left null: Bike Insights computes its own and the maker's is not on the page. Not checked against the maker's archived page: web.archive.org blocked this machine on 22 Oct 2026; a later pass should read the capture and upgrade this file to the maker's numbers. Bike Insights cites a retailer (racycles.com) for this entry and lists every size twice with the same numbers, read here once.
