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.

Notes on the source

SECOND-HAND NUMBERS: copied from Bike Insights (https://bikeinsights.com/bikes/5b8dc892bd9e870015f4d072-cannondale-bikes-topstone-alloy?version=2022&build=1), 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.cannondale.com/en-eu/bikes/road/gravel/topstone-alloy/topstone-1. 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: 1. Bike Insights files it as Road Bike / Mixed-terrain Road Bike / All-road/Gravel. Trail is left null: Bike Insights computes its own and the maker's is not on the page. The aluminium Topstone before the Topstone CAAD of MY2027 (cannondale-topstone-caad.json, sized 47 to 61). Bike Insights holds the same numbers for 2020 (citing a Cannondale US product page), 2021 (no source cited) and 2022. Seat angle 73.1 on every size. 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.
