Differing materials is largely what we are testing.
Geometry often does stay the same.
Trek make these frames:
Domane AL - entry level endurance bike, only sold as a complete bike (with Claris, Sora, Tiagra or 105)
Domane SL/SL Disc - carbon endurance frame with Isospeed suspension
Domane SLR/SLR Disc - carbon endurance frame with adjustable suspension, fancier carbon fibre
Emonda ALR/ALR Disc - lightweight alloy frame
Emonda SL/SL Disc - lightweight carbon frame
Emonda SLR/SLR Disc - ultra-light carbon frame in either H2 (standard) or H1 (lower headtube, more aggressive fit)
Madone SL - aero frame, sold only as complete bike
Madone SLR/SLR Disc - fancier carbon etc.
So the Domane AL2 (https://www.trekbikes.com/gb/en_GB/bike ... Code=black
), which is £595 all-in, has the same geometry as the
Domane SLR, which is £4k+ as a full bike, except that they seem to be selling it as frameset-only this year, the complete bikes being only disc modelshttps://www.trekbikes.com/gb/en_GB/bike ... grey_black
(note that the Domane SLR is presumably nicer to ride due to its suspension)
I am not sure the Emonda frames have identical geometry, but they are at least designed for the same purpose; it wouldn't be unreasonable to compare between ALR and SLR.
Obviously you get lighter materials on pricier bikes.
