How I read the maker's table
Product page "Substance SRS 1 Adventure Road Bike" (Reynolds 725 heat-treated cro-mo steel frame, carbon fork, SRAM Apex 1), tagged "Model Year: 2020", "Material: Steel" and "Geometry Page: substance-steel-geometry"; fitted with 650b x 47 tyres, "compatible with 700c" (wheel_size records the fitted 650b). It is a different frame from the aluminium Substance (vitus-substance): stack and reach within 0.5 mm of it, but head tubes 4 mm shorter (108 to 180 against 112 to 184), fork rake 43 against 48 and wheelbases about 7 mm shorter; Bike Insights files this steel table as its Substance 2019. Standover and trail not printed (null); stack datum not stated. Frame facts from the specification list: 12 x 142 mm rear and 100 x 12 mm fork thru-axles, BSA threaded 68 shell, 27.2 mm seatpost, mudguard, rack and three bottle mounts, external routing.
