I went to a fitter and like everyone says, and working in a jig, we got my self to fit on a size 58 domane. I bought the bike and road it couple days , and just felt too big , not sporty while I could reach the controls and all , bars prolly to wide and cranks prolly too long , so I returned it. I test road the 56 couple days ago, while the reach on 56 felt tad long, it felt more appropriate sizing for a road bike. Like more sporty .
I’m 5’11 just under 33 inseam.

Should I listen to my own instincts ?

Also when I tried a 54 it felt like it would be perfect with a 100mm stem. The 56 may require 90 or 90+ shorter reach handlebars

Should I listen to my own instincts and not follow fitters recommendation ?
should I consider a 54?
