I have been using a Giant Contend 2 for over 2 years and I am really comfortable with its geometry.
Now, I want to purchase online a Fuji Feather, with a similar fit, but I got a bit confused with their size recommendations.
The Giant Contend 2 size I am using is 535 (ML), which has 560mm top tube length. When I compare that with the Feather sizes, it corresponds to somewhere in L. The confusing part is that Giant recommends 535 (ML) for riders between 180~190cm, while Fuji recommends L for up to 180cm.
I am not an expert on bike geometries, but my guess is that I shouldn't decide the equivalent geometry based on the top tube alone, probably because the Feather has a more vintage geometry.
What other measurements should I be looking at? How can I select a size for the Feather that has a similar fit to the Contend 2?
The geometry for the Feather 2021 and 2022 is different, but I have no preference over the model year.
My height is 186cm.
