2021 Trek Fx sport 4 geometry and sizing
I bought a 2021 Trek Fx sport 4 carbon (new) in 2023 , to add to my n+1 which is a 2020 fx 3 and I always been confused about this generation fx sport carbon bike geometries. The Large Fx 3 bike, has a similar reach and stack to that of Medium 2021 Fx sport 4 carbon, why is the FX sport carbon (2021) one size larger almost for a given size ?
Is 2021 Fx Sport Carbon size Medium = Trek Fx 3 Large, interns of sizing ? I'm 6' feet tall and 32.5inseam

The FX is for beginners who like to be upright so short top tubes and taller head tubes.
